The Neotropical species of the rarely collected genus Bolitogyrus (Coleoptera: Staphylinidae: Staphylininae: Staphylinini) are revised. The genus exhibits an uncommon, disjunct distribution between the Neotropical and Oriental Regions and is of unknown phylogenetic position within Staphylinini. Morphological evolution remarkable for Staphylinini was discovered within Bolitogyrus, including sexually dimorphic modifications of the pronotum that may be involved in male competition for females. rSEM interactive animations were used to establish morphological species boundaries between two highly variable species and are provided to illustrate diagnostic characters of the genitalia in unconventional views. The genus is redescribed based on the world fauna and twenty-eight Neotropical species are considered valid. Of these, nineteen are described as new to science: Bolitogyrus ashei sp. n.; B. apicofasciatus sp. n.; B. brevistellus sp. n.; B. bufo sp. n.; B. cheungi sp. n.; B. cornutus sp. n.; B. divisus sp. n.; B. falini sp. n.; B. gracilis sp. n.; B. inexspectatus sp. n.; B. longistellus sp. n.; B. marquezi sp. n.; B. newtoni sp. n.; B. pseudotortifolius sp. n.; B. pulchrus sp. n.; B. silex sp. n.; B. thomasi sp. n.; B. tortifolius sp. n.; and B. viridescens sp. n. Bolitogyrus sallei (Kraatz), stat. r. is removed from synonymy with B. buphthalmus (Erichson) and the following new synonyms are proposed: Cyrtothorax cyanescens Sharp, 1884, syn. n. = Quedius buphthalmus Erichson, 1840; C. nevermanni Scheerpeltz, 1974, syn. n. = C. costaricensis Wendeler, 1927. A summary of all available bionomic and distributional data, as well as an illustrated identification key to and diagnoses of all Neotropical species are provided.

Bolitogyrus
Chevrolat (Staphylinidae:
Staphylininae:
Staphylinini)
is a rarely encountered genus of rove beetles that
exhibits a widely disjunct distribution in the northern
Neotropical and Oriental regions. This distribution
pattern is uncommonly reported in insects but is found
elsewhere in the rove beetle tribe Staphylinini
between sister genera Alesiella
Brunke and Solodovnikov (Oriental) and Quediomacrus
Sharp (northern Neotropical), and within the genus Misantlius
Sharp. The disjunction between Alesiella
and Quediomacrus
was attributed to vicariance following the Early Eocene
climatic optimum when subtropical forests were more
widespread, allowing for broad ‘boreotropical’
distributions across land bridges in the Atlantic and
Pacific oceans (
Despite the vivid coloration and relatively large size
(> 1 cm) of some species (Figs 1–2), Bolitogyrus
is poorly known taxonomically and rare in collections. It
is a member of the diverse (> 5700 species (A. Newton,
unpublished database)) and globally distributed rove
beetle tribe Staphylinini
(Staphylininae)
but its sister and genus group relationships remain
unclear. Recent molecular and morphological phylogenetic
analyses of Staphylinini

The monophyly of Bolitogyrus
has never been rigorously tested but

Specimens without GIS coordinates on their labels were
georeferenced using either Google Earth or Fuzzy
Gazetteer (http://isodp.hof-university.de/fuzzyg/query/).
Localities published in the Biologia Centrali-Americana
(Sharp 1888) were georeferenced using
All specimens were examined using a Leica MZ APO stereomicroscope. Specimens to be dissected were relaxed in distilled water and then the genital segment (and sometimes abdominal segment VIII) was removed. Genitalia were cleared in a 10% potassium hydroxide solution and then washed with distilled water, then with 70% alcohol and finally placed in glycerin for observation. Genitalia were placed in glycerin-filled vials for long-term storage, which were pinned with their respective specimen.
Line illustrations were digitally drawn from reference photographs in Adobe Illustrator CS v5.1. All photographs were taken using a Leica DFC 420 camera attached to a Leica MZ16A microscope with the help of Leica Application Suite (Leica Microsystems). Photomontage was accomplished using Zerene Stacker (Zerene Systems LLC) and photos were edited in Adobe Photoshop CS v5.1.
Specimens for examination using scanning electron
microscopy were first cleaned of extraneous tissue,
dehydrated in 96% ethanol, then acetone and air dried
before mounting. Specimens were secondarily mounted on an
SEM stub using aluminum tape and sputter coated with
platinum/palladium. rSEMs of genitalia were created using
the methodology outlined in
Distribution maps were created using QGIS (2013), with Natural Earth (naturalearthdata.com) vector layers for countries and states/provinces, and a raster background layer (cross blended hypsometric tints with shaded relief and water) to highlight topographical patterns. Specimens with only country or state-level locality data or considered mislabeled were not included in distribution maps. Cases of suspected mislabeling or incorrect locality names are discussed individually under their respective species.
All measurements were made using an eyepiece ocular micrometer placed in the abovementioned microscope. Measurements were taken as listed below, but only proportional (HW/HL, PW/PL, EW/EL, ESut/PL, PW/HW) and forebody measurements were stated directly in descriptions due to a wide variability in body size. Total body length is generally not diagnostic of Bolitogyrus species and was not measured due to the contractile nature of the abdomen. Measurements of the eyes were taken but as very few consistent interspecific or sexual differences were found, these values are not given. In most species, eyes generally occupied a larger proportion of the head width in females but much overlap in variation was observed.
HL: Head Length, at middle, from the anterior margin of frons to the nuchal ridge.
HW: Head Width, the greatest width, including the eyes.
PL: Pronotum Length, at middle.
PW: Pronotum Width, greatest width.
EL: Elytral Length, greatest length taken from level of the anterior most large, lateral macroseta to apex of elytra (this seta can be seen in Fig. 9B, C and F). This length approximates the length of the elytra not covered by the pronotum and therefore contributing to the forebody length.
ESut: Sutural Length, length of elytral suture.
Forebody: HL + PL + EL.
A specimen level dataset was made available as a Darwin Core Archive (http://ipt.pensoft.net/ipt/resource.do?r=neobolito1) and was deposited in GBIF.
A revision of the Neotropical Bolitogyrus species resulted in the discovery of 19 new species, 2 new synonyms and the revalidation of Bolitogyrus sallei (Kraatz), resulting in a total of 28 valid species. The species were organized into five putative species groups to facilitate comparisons between species. Four of these five species groups were included inside a larger lineage concept, the ‘Bullatus Lineage’ (see checklist below). Three species were not placed to any of the species groups and monotypic groups were avoided. Currently, the country with the greatest number of species is Costa Rica with 13 species, followed by Mexico and Panama with 9 species each. However, the available material from each of the latter countries is a third or less of that available from Costa Rica. As far as known, the number of putatively endemic species is greatest in Costa Rica with 8 species known only from that country.
Bolitogyrus
is distributed in two widely disjunct areas. In the
Oriental region, we have seen specimens from southern
India, Meghalaya, Nepal and West Bengal, Myanmar south to
Java and Borneo, north to Taiwan and Mainland China. The
genus was not previously known from Myanmar but several
widespread southeast Oriental species occur there
(Brunke, unpublished data). The northernmost
Oriental specimen known is from northeastern Sichuan
province, China (
Very early on in the taxonomic history of the genus, it
was known that species of Bolitogyrus
were found in or on fungus or fungus covered, rotten logs
(e.g.,
Although specimens are occasionally collected passively by Malaise or flight intercept traps, far greater success has been achieved by low scale insecticide ‘fogging’. The method involves placing a white cloth sheet underneath or beside a rotten log and spraying the log with a pyrethrum or pyrethroid-based insecticide (those advertising residual activity on the label were not used). Almost immediately afterward, arthropods can be found on the sheet and placed into alcohol or another killing agent. Just over half of all specimens included in the present revision were collected by this method (50.8%, 363/715) compared to flight-intercept (11.2%, 80/715) or Malaise traps (5.5%, 39/715). The remaining specimens were mostly collected by hand from fungusy wood. The Neotropical Bolitogyrus species apparently do not normally inhabit the leaf litter layer as only 1.5% (11/715) of specimens were collected by sifting leaf litter or processing it in a Berlese funnel. The use of fogging in the Neotropics is limited to relatively few localities and has primarily been utilized by staff at SEMC (Kansas, U.S.A) (e.g., J. S. Ashe, Z. Falin) and by P.N. Thomas (Illinois, U.S.A), with most collecting events in Costa Rica. It is therefore unsurprising that the majority of material included herein (81.9%) is derived from these two sources alone.
Morphological terminology generally follows that of
Sculpture of the forebody
Unlike the Oriental species, the Neotropical Bolitogyrus possess several raised areas of the cuticle that are diagnostic of species, species groups or large lineages within the genus. On the dorsal side of the head there may be a central protuberance (Fig. 6A) and a pair of posterior head protuberances (Fig. 6A) that are delimited by impressed areas of the cuticle. In most species of Bolitogyrus, the frons has a Y or X-shaped frontal impression though it is weakly impressed in the Neotropical species (Fig. 6A) compared to the Oriental species. Anterior to this impression are minor protuberances that are generally not diagnostic, as they may exhibit wide intraspecific variation. In all Neotropical species, there is a pair of medial depressions on the pronotum (Fig. 7B) and in most species, a pronotal protuberance between them that is best observed in lateral view (Fig. 7E–H, 8A–E). The elytra may possess elytral protuberances (e.g., Fig. 8E) but the size and shape of these are rather variable within species and were generally not found to be of diagnostic value.
Sexual dimorphism of the pronotum
The pronotal protuberance can be developed in the
following states: absent in both sexes (e.g., Bolitogyrus
bechyneorum
Scheerpeltz); distinct in males but barely visible in
females (e.g., Bolitogyrus
costaricensis
Wendeler) (Fig.
7E–F); more or less equally well developed in both sexes
(e.g. Bolitogyrus
divisus
Brunke, sp. n.) (Fig. 7G–H); or produced into a horn in
males but not in females (e.g. Bolitogyrus
bufo
Brunke, sp. n.) (Fig. 8A–B). In Bolitogyrus
cornutus, a
male was observed with a ‘female-like’ pronotum (Fig. 8D),
demonstrating polymorphism for these traits (Fig. 8C–E).
An analogous pattern of male polymorphism is known in
dung beetles (Scarabaeidae:
Scarabaeinae)
where female-like, smaller males gain access to
copulations with females by avoiding male-male
competition (
Margin of the pronotum
The pronotal margin of all Bolitogyrus species is more or less expanded and explanate, at least narrowly (Fig. 7A–D); only in some Oriental species does it become strongly expanded basally and basolaterally (Fig. 7A). In many Neotropical species, the lateral portions of the pronotum have become strongly explanate rather than the margin itself (Fig. 7B–D).
Abdomen
In all Neotropical species of Bolitogyrus, the anterior transverse basal carina of each abdominal tergite is extended posteriad and reaches or exceeds the level of the spiracles (Fig. 12B, E; 13E–F). In the Oriental species, this line is transverse or, rarely, sinuate (Fig. 12A). If demonstrated to be synapomorphic, this character would indicate a single origin of the Neotropical species.
Division of the median lobe of the aedeagus
In some Neotropical species, the median lobe has become divided into two lateral lobes (Fig. 19K; 20A, H) or bears a median suture in its apical third (e.g., Fig. 21L) (Divisus and Cornutus Groups), which may indicate a re-fusion of the lateral lobes. In Bolitogyrus cornutus, the median lobe bears a medioapical notch and more strongly sclerotized areas that trace an outline similar in shape to the lateral lobes (Fig. 21J).
Female genital segment
In many Bolitogyrus species, female tergite X is typical of Staphylinini and entirely separate from laterotergal sclerites IX (Fig. 25A–L; 26A–F). In these species the disc of tergite X may be raised above the plane of the lateral portions to create a shape that is often diagnostic (e.g., Fig. 26A). The basal margin of female tergite X in other species (e.g., Bullatus Lineage) may be thickened and fused with the basal margin of laterotergal sclerites IX (Fig. 26H). This fused structure may be expanded posteriad to form an accessory sclerite (Fig. 26G), which can become independent of laterotergal sclerites IX (e.g., the Divisus and Cornutus Groups) (Fig. 27C). Some species with an accessory sclerite may have the basal half of tergite X strongly reduced (Fig. 27C). The medial margins of laterotergal sclerites IX in the Bullatus Lineage have become variably expanded toward the center, covering portions of tergite X (Fig. 27C). In Bolitogyrus cheungi Brunke, the laterotergal sclerites have expanded and fused overtop tergite X, which is reduced to an anchor-shaped sclerite (Fig. 27F). Species with complex female genitalia tend to have males with complex aedeagi and the functional morphology of these characters warrants further research.
The first instance of the genus group name ‘Bolitogyrus’
was in
Fauvel (1858) was the first to recognize that the genus
also occurred in the Oriental region and described Cyrtothorax
vulneratus
from ‘Cochinchine’ (= southern Vietnam) and Cyrtothorax
carnifex
from Cambodia. In the Biologia Centrali Americana,
Unfortunately, no Neotropical species of Bolitogyrus
have been described or otherwise treated since
Bolitogyrus
can be easily recognized among other Staphylinini by
its characteristic habitus (Figs 1–2) and
the following five characters: antennomeres I–V without
dense, tomentose pubescence (Fig.
5A–E); lateral face of hind tibia without spines, only
setae (Fig.
11F); eyes strongly convex and occupying nearly entire
lateral head length (Fig.
6A–G); disc of head and pronotum without
microsculpture (sometimes fragments of microsculpture
present around roughly sculptured areas); elytral
punctures not limited to discrete rows and without
appressed setae typical of Staphylinini,
punctures asetose except those bearing erect (usually
long and coarse) macrosetae in a sutural, discal and
lateral row (best visible in Fig. 9B
and 10D).

This species group includes those Neotropical species without the central protuberance on the head and with a median lobe that is sharply constricted in parameral view (e.g., Fig. 15A) (Bolitogyrus buphthalmus, Bolitogyrus costaricensis, Bolitogyrus erythrurus, Bolitogyrus fulgidus, Bolitogyrus pulchrus, Bolitogyrus sallei, Bolitogyrus salvini). Although Bolitogyrus erythrurus and Bolitogyrus fulgidus are known only from females, they are provisionally placed here based on a combination of the first character, habitus and overall similarity of female tergite X to others of this group. This species group is widespread and occurs from Mexico to Panama.

Figure
29A. Bolitogyrus
buphthalmus
is known from Puebla and Veracruz in Mexico, and in
southern Guatemala. It is likely that the distribution
in Mexico extends much further south but more
collecting is needed in Oaxaca and Chiapas. The record
for Oaxaca given by
Bolitogyrus buphthalmus has been collected in tropical and cloud forests from 487–1737m, in association with fungusy or rotten logs. Specimens have been collected in February to March and May to July.
Bolitogyrus buphthalmus is most similar to and is only reliably separated from Bolitogyrus costaricensis by characters on the male genitalia. The pigmented area of female tergite X on the available, male-associated females is distinctly more incised at the apicolateral margin than in Bolitogyrus costaricensis. All confirmed specimens of Bolitogyrus buphthalmus south of Mexico (in Guatemala) are deep purple on the forebody, indicating that this population may be partially or entirely isolated from the population in Mexico. One male seen from Guatemala (Cerro Zunil) is metallic bronze-green and possesses peg setae fields characteristic of Bolitogyrus buphthalmus but the median lobe in lateral view is recurved dorsad as is characteristic of Bolitogyrus costaricensis. This specimen is difficult to assign to a species but may represent a hybrid between Bolitogyrus buphthalmus and Bolitogyrus costaricensis within the overlap of these two species’ distributions. Alternatively, the shape of the parameral peg setae fields may be shown to be unreliable with the study of additional material; this specimen would then be assigned to Bolitogyrus costaricensis based on the median lobe. All other males studied from Guatemala were unambiguously identified as either species.

Morphology as in Bolitogyrus buphthalmus, differing only in the following: metallic reflections of body bronze to greenish or grayish-bronze or violet to violet-blue; median lobe in lateral view recurved dorsad (Fig. 15F); peg setae fields broad and circular at base of parameral lobe (Fig. 15G–H); male sternite IX with apical emargination deeper (Fig. 23B); female tergite X with strongly pigmented area not or weakly incised lateroapically (Fig. 25A–D).
Figure 29A–B. Bolitogyrus costaricensis is known from Guatemala, Honduras, Nicaragua and Costa Rica, west to the northern part of the Talamanca Cordillera. Two females from Belize were seen that might belong to this species or Bolitogyrus buphthalmus. The specimen from Limón province in Costa Rica was almost certainly collected from elsewhere as Parismina is a city located on the Caribbean coast, situated at sea level, which is distinctly outside the elevational range of this species.
Most specimens of Bolitogyrus costaricensis have been collected by pyrethrum fogging of fungusy logs, while others were collected from bracket fungi, dried mushrooms, small crustose polypores, fungi in the family Xylariaceae, various woody debris and in FIT or Malaise traps; one slightly teneral specimen came to light. Bolitogyrus costaricensis has been collected in forests at elevations ranging from 600-2062 m in every month of the year.
Bolitogyrus costaricensis is most similar to Bolitogyrus buphthalmus and can only be separated from it by characters on the aedeagus (see above).

Similar to Bolitogyrus buphthalmus and differing only in the following: legs bicolored or not (legs of syntype not distinctly bicolored, possibly discolored due to killing agent or age); with metallic reflections as in Bolitogyrus costaricensis; narrow apex of segment VII, segment VIII and genital segment yellow to orange, distinctly contrasting with previous segment; female tergite X with raised area more elongate and widest near base; outline of female tergite X widest near middle.
Figure 29B. Bolitogyrus erythrurus is known from the Talamanca Mountain Range: southern Puntarenas in Costa Rica and the adjacent province of Chiriquí in Panama.
Specimens were collected from May-June at elevations ranging from 1300–1350m. One specimen was pyrethrum-fogged from a fungusy log.
The female syntype and three other females studied
differ from others of the Buphthalmus Group by the
pale abdominal apex, bicolored antennae and overall
shape of female tergite X. The shape of female tergite
X is roughly similar to that of Bolitogyrus
buphthalmus,
Bolitogyrus
costaricensis
and Bolitogyrus
sallei
but some slight differences were observed (see
Description). Previous authors, including Kraatz,
apparently overlooked the pale abdominal apex of the
holotype, which was partially retracted into the
preceding segments and less noticeable due to the
teneral coloration of the remaining abdomen. This dark
red coloration on abdominal segments V–VII described

Similar to Bolitogyrus buphthalmus and differing only in the following: head with metallic green to greenish-bronze reflections; pronotum varying from bright orange-red to dark reddish brown with a metallic greenish-bronze reflection and broadly reddish margins; elytra with metallic blue to greenish-bronze reflection, epipleuron and extreme base of elytra partly reddish; abdominal segments III–V reddish, with variable amounts of darkening both dorsally and ventrally; entire abdominal segment VI and base of VII dark brown, apex of VII onward, including genital segment, yellow to orange, distinctly paler than previous segments; antennomeres XI or X–XI paler than preceding segments; legs not distinctly bicolored: coxa light reddish-brown and remainder of legs either equally pale or gradually darkened to dark brown, toward apex of tibia; median frontal impression weak; head with impunctate area in middle of disc; last segment of labial palpus distinctly setose, setae more numerous and longer than in Bolitogyrus buphthalmus; pronotum with pair of depressions but without distinct protuberance in lateral view; surface of elytra relatively even, without distinct protuberances; disc of tergites III–V and sometimes VI, impunctate at middle; sternites III–IV and usually V with basal transverse lines sharply projected posteriad at middle; female tergite X transverse to weakly transverse, sharply produced apically, with beveled apex (Fig. 26E–F); female gonocoxite distinctly swollen at base (Fig. 27H).
Figure 29C. Bolitogyrus fulgidus is known from Nicaragua and Costa Rica (not east of the Central Cordillera).
Bolitogyrus fulgidus has been collected in April, October and December/January at elevations ranging from 50–1550 m (but see below). All specimens with collecting data were captured in Malaise traps. Currently only females have been collected and nothing is known about this species’ microhabitat preferences. It is notable that this species was never collected by fogging fungusy logs or from other fungi. It is possible that this species normally occurs in a forest stratum higher than accessed by most collecting efforts.
Bolitogyrus fulgidus is most similar to Bolitogyrus pulchrus and Bolitogyrus salvini but may be easily distinguished by the bicolored antennae and pale base of the elytra. Four recently collected female specimens Bolitogyrus fulgidus from Costa Rica are included in this species concept based on the shape of female tergite X, though in one specimen (SM0694452), the tergite is distinctly more elongate (Fig. 26F), antennomere X is not paler than the preceding segments, the pronotum-to-head width ratio is slightly greater, and the elytra are slightly longer. This specimen was also collected at a much higher elevation (1550 m) than the other specimens including the holotype (50-620 m) and from a locality on the Pacific slope of the continental divide in Costa Rica. Bolitogyrus fulgidus is otherwise known from the Caribbean lowlands of Nicaragua and Costa Rica. Additional collecting in Costa Rica will hopefully determine the identity of this specimen from the Pacific cloud forest, especially if males of this species are discovered from both side of the divide.

Figure 29C. Known from the Talamanca Cordillera in Costa Rica and in adjacent Panama (Chiriquí province).
This species has been collected in May and June/July at 1150 and 2150 m from a flight intercept trap and by hand collecting. Nothing is known about this species’ habitat preferences.
The species epithet means ‘beautiful’ in Latin and refers to the striking combination of metallic purple and non-metallic red in this taxon.
Bolitogyrus pulchrus is most similar in habitus to Bolitogyrus fulgidus but can be distinguished by the dark antennae and abdominal apex, the more uneven elytral disc and the differently shaped female tergite X. The female specimen is from a much lower elevation on the Caribbean slope of the Panamanian portion of the Talamancas and differs from the male holotype in abdominal and head coloration. Both specimens share a dark genital segment and the unique, entirely dark antennae and legs. However, the female specimen is excluded from the type series as it may represent another undescribed species closely related to Bolitogyrus pulchrus.

Figure 29D. Bolitogyrus sallei is known only from the Mexican states of Hidalgo and Veracruz.
Bolitogyrus sallei has been collected from cloud to deciduous forest, in June and July, at elevations ranging from 841-1115 m. One specimen was collected from a rotting log and another from a flight intercept trap.
Bolitogyrus
sallei
is most similar to and sympatric with Bolitogyrus
buphthalmus
from which it differs in the smaller size of the
forebody (overlapping but rarely), the partially pale
forecoxa in females and the morphology of the
aedeagus. It is rare for very similar and thus
presumably closely related species of Bolitogyrus
to occur sympatrically but future collecting will
hopefully establish whether Bolitogyrus
sallei
and Bolitogyrus
buphthalmus
share the same habitat or microhabitat.

The male and female syntypes are identical in color and are easily separated from other species of the Buphthalmus Group based on male and female genitalia, though considerable variation exists within the present species concept. To provide nomenclatural stability for this name, the male syntype was selected and is here designated as the lectotype, as male sexual characters provide more reliable diagnostic characters than those of females in Bolitogyrus.

Similar to Bolitogyrus buphthalmus and differing only in the following: head and pronotum metallic green to greenish bronze or black, without metallic reflection; elytra reddish or black with greenish to bronze metallic reflections, base of elytra concolorous with disc; abdominal segments III–V reddish or completely dark; abdominal segments VIII and genital segment yellow to yellow-orange, distinctly contrasting with previous segments, or entirely dark and not contrasting; legs distinctly bicolored (as in Bolitogyrus buphthalmus), with dark procoxa in females, or entirely reddish (the lectotype and paralectotype); median frontal impression weak to moderately impressed (morphotype 3); head impunctate in middle of disc or not (lectotype and paralectotype); disc of tergites III–V impunctate at middle, disc of VI punctate; median lobe in lateral view recurved dorsad; apical portion of median lobe constricted at base but weakly such that base is relatively wide; paramere with arms relatively flat, not curved around median lobe, arms divergent and peg setae as illustrated, varying from dense to sparse; male sternite IX similar to Bolitogyrus buphthalmus but median emargination deeper; female tergite X distinctive, narrow at base, raised area on disc contiguous with base and not strongly converging to apex; strongly pigmented area variable at apex.
Figure 30A. This species is known from southern Mexico, Guatemala and central Nicaragua (Matagalpa and Jinotega).
All specimens were either swept from foliage or collected from Malaise/flight intercept traps during May and June. As in Bolitogyrus fulgidus, very few males are known and it is possible that this species normally occurs in a forest stratum higher than accessed by most collecting efforts. Bolitogyrus salvini has been collected from a wide range of forested habitats: from wet lowland forest (180 m) to cloud forest (1470 m).
The relatively large amount of morphological variation observed in Bolitogyrus salvini indicates that a complex of species is likely to be involved but with the material currently available, a broad concept of Bolitogyrus salvini (wide median lobe in parameral view, elongate female tergite X) is preferred. There are three different morphotypes discernable from the material at hand that will need re-assessment in the future. The male and female types (Guatemala) represent morphotype 1: reddish elytra; pale apex of the abdomen; weak median frontal impression; without impunctate area on dorsal surface of the head. Morphotype 2 is represented by four females (southern Mexico, Nicaragua): dark elytra with green to greenish bronze metallic reflections; pale apex of abdomen; weak median frontal impression; with impunctate area on dorsal surface of head. Morphotype 3 is represented by two males and one female (Mexico, north of second morphotype): dark elytra with bronze metallic reflection; dark apex of abdomen; moderately deep median frontal impression; impunctate area on dorsal surface of head. The first and third morphotypes have males available and can be distinguished (at present) by the peg setae on the paramere: morphotype 1 with distinctly fewer peg setae (therefore sparser) than morphotype 3 (Fig. 16F versus 16G–H).
The species included in this lineage all share a raised, circular protuberance on the vertex, between the eyes (Fig. 6A), a feature not found in any other taxa in the tribe Staphylinini. This relatively large group of Neotropical species likely forms a monophyletic lineage of the genus and is a useful concept to contain other, smaller species groups. The Bullatus Lineage is distributed across the entire Neotropical range of Bolitogyrus, from Mexico to Ecuador.

Figure 30B. Bolitogyrus bullatus occurs along the Tilarán, Central and Talamanca Cordilleras (Costa Rica and western Panama).
Bolitogyrus bullatus has been collected using a variety of passive collecting methods (Malaise, FIT), fogging fungusy logs and by sifting leaf litter and decaying wood debris, which were sometimes processed in Berlese funnels. Specimens were also hand collected directly from fungi including ‘small white gilled’ and ‘orange gilled’ mushrooms, ‘Clistocybe?’ and ‘Favolus hexagonus’. This species has been collected in mid-elevation forests at elevations ranging from 1050-2460 m, in all months of the year.
Among species of similar distribution, Bolitogyrus bullatus is most similar in habitus to Bolitogyrus falini and the dark species from the Ashei Group. It can be easily distinguished by the single puncture in the dorsal row of the pronotum. Within its distribution, Bolitogyrus bullatus is the most commonly collected species of the Bullatus Lineage. Given the wide elevational occurrence of Bolitogyrus bullatus, the populations of the Tilarán, Central and Talamanca Cordilleras appear to be, at most, weakly isolated from each other. However, the specimens from west of the Central Cordillera are all females and males are needed to fully confirm the occurrence of Bolitogyrus bullatus there. This species shows a wide range of external morphological variation, none of which corresponds with the observed variation of the paramere and median lobe. Only color appears to be geographically correlated: an extreme color morph exists in some Panamanian populations where the abdomen is solid red ventrally except for the apex of sternite VII and entire VIII. However, intermediates between the typical red striped and solid individuals were observed from Panama and also Costa Rica.

Figure 30B. Known from Chiapas, Mexico and Quetzaltenango, Guatemala.
Specimens were collected in cloud and mesophil forests at 1520–1620 m, by beating vegetation and from an Auricularia (jelly) fungus, during May and June.
The specific epithet means ‘apical band’ and refers to the dark color band of the hind femur, which is situated distinctly closer to the apex than in Bolitogyrus bullatus.
Within its distribution, Bolitogyrus apicofasciatus cannot be confused with any described species of Bolitogyrus.
The species of the Ashei Group (Bolitogyrus ashei, Bolitogyrus pseudotortifolius, Bolitogyrus tortifolius) share an asymmetrical, somewhat leaf-shaped paramere (e.g., Fig. 19A, D) and a relatively short and truncate female tergite X that is unmodified at the base and is distinctly shorter than the laterotergal sclerites (about half the length) (Fig. 26K); both of these characters are unique to this group in the Neotropical Bolitogyrus. The Ashei Group is endemic to Costa Rica as far as known.

The male holotype was fogged from a fungus-covered log in July, at 1150 m and the female specimen was collected in a Malaise trap during February-March at a similar elevation.
It is our pleasure to dedicate one of the most
spectacular species of Bolitogyrus
to the late Dr. James Stephen (“Steve”) Ashe
(1947–2005). The Bolitogyrus
material from the University of Kansas (SEMC) insect
collection has proven critical to the present
revision, and Steve was the driving force behind and
co-collector of the majority of these specimens. His
passion for Staphylinidae,
including Bolitogyrus
is remembered in
Bolitogyrus ashei cannot be confused with any other member of the Bullatus Lineage. The female specimen was not included in the type series as it differs in coloration (completely orange head, purple elytra) and was collected on the Caribbean side of the continental divide in Costa Rica. As both specimens were collected at relatively low elevations (1050-1150 m), they may each represent allopatric species on either side of the continental divide. Additional specimens, especially males, are needed to re-evaluate this hypothesis.

Bolitogyrus tortifolius has been collected in May and June, by FITs and on a white Crepidotus sp. fungus. Specimens have been found at elevations of 1515–1610 m.
The species epithet refers to the paramere of the aedeagus, which is similar to a curled leaf.
Among species of overlapping distribution, Bolitogyrus tortifolius is most similar in habitus to Bolitogyrus divisus and Bolitogyrus bullatus. It can be easily distinguished by the pronotum with two punctures in the dorsal row. At present, the only male-associated female of Bolitogyrus tortifolius can be distinguished from females of Bolitogyrus pseudotortifolius by the shape of female tergite X, which is wider and more truncate at the apex than in the previous species.

Figure 30C. Bolitogyrus pseudotortifolius occurs along the Central and Talamanca Cordilleras in Costa Rica and Panama, on the Caribbean side of the continental divide.
Bolitogyrus pseudotortifolius has been collected in March-June, at 1050-1200 m (once at 1340 m), by fogging logs and using passive traps (FIT, Malaise). The specimen from Cartago, Costa Rica is not included in the distribution map as it was collected from cut logs that appeared to have originated from elsewhere (P.N. Thomas, pers. comm.). One relatively pale specimen may be teneral and was collected by processing forest litter in a Berlese funnel. This specimen may indicate the litter layer as a site for pupation or even a larval habitat.
The specific epithet refers to the similarity of Bolitogyrus pseudotortifolius with Bolitogyrus tortifolius.
Among species of overlapping distribution, Bolitogyrus pseudotortifolius is most similar in habitus to Bolitogyrus falini and Bolitogyrus bullatus. It can be easily distinguished by the pronotum with two punctures in the dorsal row. The available specimen data on Bolitogyrus pseudotortifolius and Bolitogyrus tortifolius suggest that these two species are allopatric and that, the former may be broadly distributed along the Caribbean foothills of the continental divide in Costa Rica and Panama.
The species of this group exhibit a marked sexual dimorphism of the pronotum in which the male pronotal protuberance is developed into a rounded or blunt ‘horn’ (Fig. 8A–F). Most females of species in the Cornutus Group can be identified as such by the pronotum with four punctures in the dorsal row and with lateral margins strongly converging anteriad. Bolitogyrus cornutus has only two punctures in the dorsal row but females can be identified to species by external characters given in the key and in the corresponding diagnosis below. The Cornutus Group is the most speciose group within the Bullatus Lineage and the only one to occur in South America. This species group is distributed from Costa Rica to Ecuador.

Figure 31A. Known from the foothills of the Andes in Columbia and Ecuador. Bolitogyrus cornutus is the only species of the genus known to occur in South America and may occur farther north in Venezuela.
Specimens of Bolitogyrus cornutus have been collected from elevations ranging from 700-1375 m, from fungus-covered logs and from Malaise traps during February to March and May to October.
The species epithet refers to the strongly developed pronotal protuberance of male Bolitogyrus cornutus. This species possesses the most strongly modified pronotum in the genus Bolitogyrus.
Bolitogyrus cornutus is currently the only species of the genus known from South America and thus, can be recognized by distribution alone. One unassociated female (BMNH) from the vicinity of the type locality may belong to this species but, as it was collected at a substantially higher elevation (1700 m), remains unidentified.
The sexual dimorphism of the pronotum observed in this species is striking and the most pronounced in the entire genus (Fig. 8C–F). However, one male specimen from Columbia was observed with some female-associated characters including a pronotum with a small and rounded protuberance (Fig. 8D) and a less transverse head (1.90 versus 1.98–2.10 in other males). It is also smaller than the other males but size was not found to be sexually dimorphic in this species (see measurements). Its aedeagus is identical to that of other males from the same collecting event, suggesting that males of Bolitogyrus cornutus may be polymorphic for secondary sexual traits and possibly any behavior related to them.

Figure 30D. Known only from the type locality in Veraguas province, Panama.
Bolitogyrus brevistellus has been collected from a fungusy log in June at an elevational range of 1110–1210 m.
The species epithet means ‘short constellation’ and refers to the relatively short fields of peg setae (like a constellation of stars) on the paramere, a character that separates it from the similar Bolitogyrus longistellus.
As far as currently known, Bolitogyrus brevistellus is not sympatric with any species of the genus but is extremely similar to Bolitogyrus longistellus from Panama province, Panama. The forebody of Bolitogyrus brevistellus is distinctly paler than the holotype of Bolitogyrus longistellus but identifications should be based on dissected males until more specimens are available.

Bolitogyrus bufo has been collected at elevations ranging from 1150-1600 m, using flight traps and by fogging fungus covered logs. Collections are known from March, May-July and October-November.
The species epithet is the Latin word for toad. It refers to the similarity between the roughly sculptured, light brown cuticle, typical of Bolitogyrus bufo and the rough, warty skin of a true toad (Bufonidae). It is to be used as a noun in apposition.
Within its distribution, Bolitogyrus bufo is not easily confused with any other species due to the pale coloration and coarse sculpture. It is extremely similar to Bolitogyrus thomasi from the Caribbean side of the continental divide in Heredia, Costa Rica but can be distinguished by the differently shaped emargination of male sternite VII and the differently shaped paramere.

Bolitogyrus cheungi has been collected from fungusy logs at an elevational range of 1200–1350 m in June.
The first author dedicates this species to his partner, David K.-B. Cheung. His support and understanding during this project, while away from home and family, were greatly appreciated.
The relatively small pronotal protuberance of the male paratype compared to that of the holotype may indicate some interesting polymorphism in this trait, similar to that of Bolitogyrus cornutus (see discussion under ‘Natural History’) but too few specimens are known to confirm this. Bolitogyrus cheungi is not sympatric with any other known species of Bolitogyrus but is most similar to Bolitogyrus longistellus. At present, it can only be reliably separated by the distinctively bilobed aedeagus. The lateral lobes of the aedeagus in Bolitogyrus cheungi differ in shape from those of the Divisus Group and it is uncertain whether they are homologous to those of the latter. Phylogenetic analyses using a variety of morphological character systems may resolve this in the future and ascertain whether the Divisus and Cornutus Groups are natural lineages.

Bolitogyrus gracilis has been collected from fungusy logs at an elevational range of 1000-1250 m in May and June.
The species epithet means ‘slender’ and refers to the slender habitus created by the relatively long and thin abdomen, especially of male specimens.
Bolitogyrus gracilis is not sympatric with any species that could be confused with it due to the pale coloration and coarse sculpture but is most similar in habitus to Bolitogyrus bufo, Bolitogyrus thomasi, Bolitogyrus brevistellus and Bolitogyrus cheungi. Without distributional information, males of Bolitogyrus gracilis should be dissected to confirm their identity.

The holotype was collected in tropical rainforest at 370 m in June.
The species epithet means ‘long constellation’ and refers to the relatively long fields of peg setae (like a constellation of stars) on the paramere, a character that separates it from the similar Bolitogyrus brevistellus.
As far as known, Bolitogyrus longistellus is not sympatric with any other species of Bolitogyrus but is most similar in habitus to other members of the Cornutus Group. Without distributional information, it can be reliably separated only by the characteristic paramere.

Figure 30D. Known only from the type locality on the Caribbean foothills of Barva Volcano in the Central Cordillera, Costa Rica.
The holotype was captured by a flight intercept trap at 1050-1150 m in March.
The first author would like to dedicate this species to his colleague Paul N. Thomas (Chicago, Illinois, U.S.A.), whose collecting expeditions in Costa Rica resulted in a significant and dominant portion of the material studied for the present revision.
Bolitogyrus thomasi is most similar to other species of the Cornutus Group, especially Bolitogyrus bufo. However, none of these species are sympatric with it. Without distributional information, males may be identified by the deep emargination on sternite VII, which is about as deep as wide.
The three members of this group (Bolitogyrus divisus, Bolitogyrus falini and Bolitogyrus inexspectatus) share the following characters: lateral margins of pronotum only weakly convergent anteriad, margins nearly straight in anterior half (Fig. 7D); median lobe divided into two slender arms each bearing a subapical tooth (e.g., Fig. 20A). The median lobe of Bolitogyrus cornutus (Cornutus Group), while entire, does show an indication of the two arms with subapical teeth, traced by faint lines. However, this species was placed with other species of the Cornutus Group due to characters on the pronotum (see Cornutus Group). The Divisus Group is endemic to Costa Rica as far as known.

Coloration: Body dark brown, portions of frons occasionally with faint green-blue metallic reflection, pronotum with faint bronze metallic reflection; pronotum with base narrowly, and lateral portions broadly and distinctly paler, dark orange, pronotal protuberance often paler, pale lateral areas sometimes joining with that on pronotal protuberance; elytra reddish brown with epipleuron distinctly paler, yellowish, apex of elytra indistinctly paler; dorsal abdomen with segments III–V reddish brown, VI–VII darker, dark brown, tergite VII with variably shaped, apical, orange marking, tergite VIII usually entirely pale, yellow, sometimes yellow at base and dark at apex; genital segment of both sexes pale, yellow; antennomeres I–V pale, yellowish brown, some segments sometimes slightly darker, antennomeres VI–X dark brown, apical antennomere distinctly paler than previous, yellow to pale yellowish-white; maxillary and labial palpi yellow-brown; legs yellow to yellowish brown, femur with dark subapical band, profemur with dark band weakly formed, nearly absent on some specimens, tibia with darkened lateral face.
Head with median frontal impression present as a pair of subparallel lines forming the anterior margin of central protuberance, impression often obscured by sculpture; frons relatively coarsely sculptured, slightly glossy; base of head with well-developed posterior protuberances, surface smooth, glossy, with several coarse, sparsely distributed, asetose punctures; microsculpture absent dorsally except as broken lines on frons and well-developed, fine lines on temples.
Pronotum with disc smooth, glossy, with scattered fine to coarse micropunctures on disc; lateral areas with moderately impressed, irregularly spaced, asetose punctures, often contiguous; pronotal protuberance distinct in lateral view but slightly less pronounced in females; lateral margins of pronotum only weakly convergent anteriad, sides nearly straight in anterior half; with three punctures in dorsal row; scutellum with a few separated, moderately impressed, asetose punctures; elytra slightly to weakly transverse, suture shorter than pronotum at midlength; macrosetae of elytra relatively long and erect, distinct from overall surface sculpture in lateral view.
Median lobe divided apically into two lateral lobes; in lateral view, lateral lobes produced ventrad from their base, with subapical tooth on dorsal face, tooth conical and not flattened, apex of lateral lobe not flanged, evenly cylindrical (Fig. 17E; 32A); lateral lobes in parameral view convergent apically, touching or not, forming acute to broadly rounded emargination at their base (Fig. 17A); paramere distinctly shorter than median lobe, at most, slightly divided apically but always with median suture (Fig. 17A); in parameral view, paramere constricted at midlength, strongly dilated and then constricted subapicad, narrowed very slightly to apex (Fig. 17C–D); apical portion of paramere with sides subparallel or divergent, apex blunt; with peg setae in a pair of lateral fields, strongly broadened at base, narrowed for the majority of their length and slightly widened at apex (Fig. 17F–G). Male sternite VII shallowly but distinctly emarginate and with glabrous area apicomedially, this area slightly to strongly flattened; male sternite VIII with transverse basal line complete medially, with slightly emarginate apex, impressed and glabrous in elongate triangular area near emargination; male sternite IX distinctly asymmetrical at base, with moderately deep emargination at apex (Fig. 24C).
Female tergite X strongly constricted in basal half, evenly rounded at moderately narrow apex, base of female tergite X fused with accessory sclerite formed from the expanded basal margin of the laterotergal sclerites (Fig. 27C); female laterotergal sclerites strongly expanded at base and overlapping with tergite X (Fig. 27C).
Figure 31B. This species occurs along the Guanacaste, Tilarán and Central Cordilleras.
This species has been collected at elevations ranging from 810-1450 m in flight traps, on fungi and by fogging fungus covered logs. Specimens have been collected in January-August and in October.
The species epithet refers to the division of the median lobe into a pair of lateral lobes bearing subapical teeth, a character unique to the Divisus Group of Bolitogyrus within the genus and the entire tribe Staphylinini.
Among species with an overlapping distribution, Bolitogyrus divisus is most similar to Bolitogyrus bullatus and Bolitogyrus tortifolius but is easily distinguished by the pronotum with three punctures in the dorsal row. Bolitogyrus divisus is extremely similar to Bolitogyrus falini and except for the color of the genital segment, cannot be distinguished from it without the dissection of male specimens. The shape of the paramere differs between the two species but is subject to considerable variation. In general, the sides of the apical portion are subparallel or even slightly divergent, and the apex is rather blunt in Bolitogyrus divisus. In Bolitogyrus falini, the sides are convergent and the apex is narrower. The study of the lateral lobes of the aedeagus at unconventional angles, at high magnification and resolution using rSEM animations was critical in the development of the species concept used herein. rSEM animations revealed differences in the subapical teeth and the apices of the lateral lobe that perfectly coincided with the groups created using the color of the genital segment (see descriptions of Bolitogyrus divisus and Bolitogyrus falini). All other variation observed in the aedeagi was overlapping between species when most specimens had been dissected. Although the shape of the subapical tooth and of the lobe apex are difficult to observe at lower magnifications, the color of the genital segment should allow the identification of nearly all specimens without dissection.

Bolitogyrus falini has been collected in March, May and June, and November, at elevations ranging from 1300-1660 m, from fungusy wood and using an FIT.
This species is dedicated to our colleague Zack Falin (SEMC), who collected many specimens of Bolitogyrus during extensive fieldwork in Central America.
Bolitogyrus falini is sympatric with and similar to Bolitogyrus bullatus and Bolitogyrus pseudotortifolius but can be distinguished by the pronotum with three punctures in the dorsal row. Bolitogyrus falini and Bolitogyrus divisus appear to be sister species and are widely allopatric in Costa Rica. For details on their separation, see under Bolitogyrus divisus.

The holotype was collected in February, at a relatively low elevation from a log overhanging a creek (‘Rio Chavez’) running through a ravine (P.N. Thomas pers. comm.).
Bolitogyrus inexspectatus externally resembles Bolitogyrus tortifolius and Bolitogyrus pseudotortifolius and it was initially thought that these species could be closely related. The species epithet refers to the ‘unexpected’ discovery of the distinct aedeagal characters of the Divisus Group in this species.
Of the species sympatric with Bolitogyrus inexspectatus, Bolitogyrus bullatus is the only similar species. It can be readily distinguished from it by the pronotum with two punctures in the dorsal row.
This group is composed of three species (Bolitogyrus strigifrons, Bolitogyrus silex and Bolitogyrus viridescens), which share a strigulose patch on the elytra (Fig. 9F), dense yellow abdominal setae (Fig. 13E–F) and the basal elytral ridge reconnected to the humerus (Fig. 10F). The strigulose patch on the elytra and the dense, yellow abdominal setae are unique within Bolitogyrus. This group is currently known from Mexico and Guatemala.

Figure 31C. Known only from Hidalgo and Veracruz states in Mexico.
One specimen was found in a rotten log during August at 1830 m.
Among potentially sympatric species, Bolitogyrus strigifrons is similar to Bolitogyrus viridescens but is easily distinguished by the strigulose sculpture on the head. The non-type male was received pre-dissected but, unfortunately, the tip of the paramere was missing. Despite this, I am reasonably confident that this specimen belongs to Bolitogyrus strigifrons based on the sculpture of the head and the general shape of the median lobe.

Specimens were collected in cloud forests at elevations ranging from 1430–1600 m, in flight traps, by sifting litter and on ‘crustose mushrooms’, during May and June.
The species epithet is a Latin noun meaning ‘stone’ or ‘flint’ and refers to the pair of heavily sclerotized sclerites of the internal sac that appear weighty, like stones. It is to be used as a noun in apposition.
Among sympatric species, Bolitogyrus silex not easily confused with any other species and is easily recognized by the strigulose patch on the elytra.

Bolitogyrus bechyneorum has been collected at a wide range of elevations (334-2350m) from leaf litter, dead wood and within a log with mushrooms. Most specimens were collected during June to August but one specimen each was taken in February and April.
Among sympatric species, Bolitogyrus bechyneorum is most similar to Bolitogyrus marquezi but can be easily distinguished by the metallic blue forebody and the coarse punctation of the elytra. The holotype of Bolitogyrus bechyneorum was collected from ‘Finca La Paz’ near the double-coned volcano San Vicente, which has one cone in San Vicente state and one in La Paz. ‘Finca La Paz’ could not be located but it is assumed that the holotype was collected somewhere near a coffee plantation on the western cone, which is located in La Paz state.

Figure 31D. The locality of one paratype could not be georeferenced due to vague label data (‘71 km NE Atoyac de Alvarez’). Bolitogyrus marquezi is known from Morelos and Guerrero states in Mexico.
Specimens of this species were collected at 1700–2450 m, in March and July, in treefall litter and in an oak-pine forest on fallen logs.
The first author would like to dedicate this species to his colleague Dr. Juan Márquez Luna (MZFC), the collector of the holotype and female paratype, and someone who shares an interest in this genus.
Bolitogyrus marquezi is most similar to and sympatric with Bolitogyrus bechyneorum but can easily be distinguished by the greenish-bronze forebody and finer punctation of the elytra. The holotype and paratype from Morelos state differ markedly from the male paratype from Guerrero in the abdominal microsculpture, punctation of the forebody and the coloration of the apical antennomere. However, the aedeagi of the males are very similar and differ only slightly in the shape of the parameral apex. Further study may reveal Bolitogyrus marquezi to be a complex of species but more male specimens are needed to readdress this.

Figure 31D. Bolitogyrus newtoni is known from northern Chiapas in Mexico and from Suchitepéquez state in southern Guatemala.
Specimens were collected from the forest floor and from a cluster of mushrooms on a log, at 1550–1676 m. The holotype was collected in a dung trap but an association of this species with the dung community is unlikely. Specimens were collected in June and August.
The first author would like to dedicate this species to Dr. Alfred (Al) Newton (FMNH), a friend and mentor. While collecting the holotype of Bolitogyrus newtoni, Al was sampling for Platydracus (Staphylininae: Staphylinina), a genus that he is currently revising and the subject of our first collaborative project.
Bolitogyrus newtoni is most similar to and sympatric with Bolitogyrus buphthalmus and the dark individuals of Bolitogyrus salvini (morphotype III). However, it may be distinguished by the apical antennomere which is not paler than the previous segments and the sparse, microsculpture on the ventral abdomen.
PANAMA: Darien, Cana Biological Station, 7°45'18"N, 77°41'6"W, 500-550 m, ex. fungusy log, 3.VI.1996, J. Ashe and R. Brooks, PAN1AB96 009, SM0042289, 1 ♀ (SEMC).
This single female from eastern Panama is similar to Bolitogyrus newtoni in habitus and small size, and also lacks the median frontal impression. Unlike in Bolitogyrus newtoni, the forebody has a violet-blue metallic reflection, the procoxae are pale, the hind legs are entirely dark brown, the ventral abdominal microsculpture is extremely fine and the form of female tergite X is different. It is almost certainly belongs to an undescribed species but without characters of the male aedeagus, describing a species from such a poorly collected region may create taxonomic problems in the future.
MEXICO: Jalisco: Tequila, Volcán de Tequila, bosque mesófilo [=cloud forest], ex. bajo musgo [=under moss] 2350 m, 20.II.1994, J. L. Navarrete col., 1 ♀ (CZUJ). Morelos: Cuernavaca, Ocuilan, VII.1992, A. Pérez, 1 ♂ [missing aedeagus] (CZUJ).
The male and female specimens, each from Mexico, are similar to Bolitogyrus bechyneorum in habitus, and to Bolitogyrus newtoni as they lack a median frontal impression. Unlike these two species, the elytra and abdomen, except for the apex of the latter, are reddish. The male is unfortunately missing the aedeagus and this species cannot be described.
