Abstract

The genus Urgleptes Dillon (1956) is reviewed for Hispaniola. Five new species of Urgleptes from the Dominican Republic are described herein: U. charynae Ravin & Lingafelter, sp. n. (La Vega province), U. conjunctus Ravin & Lingafelter, sp. n. (Peravia Prov.), U. curtipennis Ravin & Lingafelter, sp. n. (Independencia Prov.), U. marionae Ravin & Lingafelter, sp. n. (Monseñor Nouel Prov.), and U. obliteratus Ravin & Lingafelter, sp. n. (Pedernales Prov.). Two additional, previously described species are newly recorded for Hispaniola: U. puertoricensis Gilmour and U. sandersoni Gilmour. It is established that U. haitiensis Gilmour is a new synonym of U. sandersoni. Thus there are seven species of Urgleptes recorded for Hispaniola. For all species photographs, illustrations, full descriptions, distribution maps, and a dichotomous key are included for their identification.

Introduction

The genus Urgleptes is among the largest in the Acanthocinini (Lamiini) with 79 described species (Monné 2015). Of these, 11 species were described from the Caribbean region. These include: Urgleptes borikensis Micheli and Micheli (2004) from Puerto Rico, U. chamaeropsis (Fisher, 1926) from Cuba and the Bahamas, U. clarkei Chemsak (1966) from Peter Island and Antigua, U. cobbeni Gilmour (1963) from the Lesser Antilles, Curaçao, Bonaire, and Barbados, U. gahani Chalumeau (1983) from St. Vincent, U. guadeloupensis (Fleutiaux & Sallé, 1889) originally described from Guadeloupe, and reported from throughout the Lesser Antilles and Greater Antilles, U. haitiensis Gilmour (1963) from Haiti, U. hummelincki Gilmour (1968) from Aruba, U. leopaulini Touroult (2004) from Guadeloupe, Martinique, and Saint Lucia, U. puertoricensis Gilmour (1963) from Puerto Rico, and U. sandersoni Gilmour (1963) from Puerto Rico (Monné 2015; Tavakilian and Chevillotte 2015).

Urgleptes Dillon (1956) is very similar to the even larger genus, Lepturges Bates (1863). Species of Urgleptes have distinct punctures limited to a row along the basal transverse sulcus extending behind the lateral pronotal spines (Fig. 8e). In Lepturges, punctures along the basal transverse sulcus do not extend behind the lateral pronotal spines and there are other scattered, large punctures on the pronotal disk (Dillon 1956; Lingafelter 2007).

Results of these studies demonstrate that seven species of Urgleptes occur in Hispaniola. These include five endemic species described as new herein: U. charynae, U. conjunctus, U. curtipennis, U. marionae, U. obliteratus, and two formerly described species that represent new country records for the Dominican Republic: U. puertoricensis and U. sandersoni. We provide justification for the new synonymy of U. haitiensis with U. sandersoni.

Materials and methods

The material consulted in this study is primarily the result of expeditions from the Smithsonian Institution (second author), Carnegie Museum (John Rawlins, Robert Androw, and Robert Davidson), Florida State Collection of Arthropods (Paul Skelley and Michael Thomas), and The West Indian Beetle Fauna Project (Michael Ivie), along with the individual collections of Edmund Giesbert, Kelvin Guerrero, Charyn Micheli, Julien Touroult, Robert Turnbow, James Wappes, Norman Woodley, and many others.

Holotypes of new species described herein are deposited in the USNM and maintained on the online image database of Lingafelter, et al. (2015) following the standards and methods of Lingafelter, et al. (2014). Label data are mostly verbatim, but redundancy among paratypes is minimized by not repeating identical localities from specimens from the same institution. Specimen data are grouped in alphabetical order by provinces (which are not repeated for brevity). Haiti records are listed after Dominican Republic Records. Species description format follows Lingafelter and Micheli (2009).

Specimens were photographed with a Zeiss AxioCam HRc camera attached to a Zeiss Discovery.V20 stereomicroscope™ with a PlanApo™ 0.63X objective and Dolan-Jenner MI-150 Fiber Optic Illuminators™ with gooseneck fiber optic and ring light attachments. Image stacking was achieved by a combination of Axiovision™ and Adobe Photoshop CS6™ software.

Results and discussion

Urgleptes puertoricensis Gilmour, 1963

Figs 1, 8b, 15

Diagnosis

This species can be distinguished easily by the mostly dark brown scape, slightly flavous at the base (in U. sandersoni the scape is darkened apically with a subapical pale ring). This species is most similar to the highly variable U. sandersoni by the elytral maculae (most specimens have a darkened periscutellar region and a zigzag pubescent fascia extending from the lateral margin obliquely toward the middle combined with variable subapical maculae). The posthumeral macula never attains the base in U. puertoricensis, whereas in U. sandersoni this macula originates basally and extends along the epipleuron.

Distribution

This species was originally described from Puerto Rico and has also been recorded from the Virgin Islands (Monné 2015). Hispaniola and the Dominican Republic represent new island and country records, respectively, for this species. This species is uncommonly collected but wide ranging (Fig. 15) throughout the Dominican Republic. Most specimens have been collected by beating vegetation from May through July.

Diagnosis

The elytral maculae of this species are more variable than any other species in the genus. As discussed above, U. sandersoni is most likely to be confused with U. puertoricensis, but they can be distinguished most easily by the scape that is apically darkened with a subapical, flavous ring in U. sandersoni (mostly dark brown, without a subapical, pale ring in U. puertoricensis.) The presence of dark brown to black maculae at the base of the humeri, often extending through the epipleuron (only occurring posthumerally in U. puertoricensis) may also be used to differentiate between the two. The primarily Lesser Antillean U. guadeloupensis (Fleutiaux & Sallé) is much paler and lacks a marmorated pubescent pattern on the elytra (see Remarks for further discussion of this species).

Redescription

Measurements: body length: 3.3–6.3 mm; body width: 1.2–2.3 mm; elytral length: 2.3–4.6 mm; elytral width: 0.6–1.2 mm; pronotal length: 0.6–1.0 mm; pronotal width: 1.0–1.7 mm; body length/pronotal length: 5.3–6.1; elytral length/elytral width: 4.0; pronotal length/pronotal width: 0.6–0.7.

Head: covered in fine vestiture of golden or pale brown appressed hairs; denser along eye margins and antennal tubercles; relatively sparse on occiput and anterior margin of frons. Narrow median-frontal line mostly visible, extending from frons through vertex, and posteriorly to occiput. Frontal-genal line extending from anterior tentorial pits along anterior margin of genae to base of mandible; mostly obscured by dense, golden, appressed pubescence. Antenna: mostly pale brown; covered with short, appressed, fine pubescence, not obscuring surface. Antennomeres 1–8 with distinct, narrowly dark brown apices; scape also with second, diffusely dark annula at apical two-thirds; antennomeres 9–11 vaguely darkened apically. Antennae considerably longer than body; extending beyond elytral apices by 4–5 antennomeres; scape extending to posterior margin of pronotum. Eye: Lower eye lobe over twice height of upper eye lobe; extending over half distance between antennal tubercle and frontal margin; lobes connected by 3–4 rows of ommatidia at narrowest point, in most specimens. Upper eye lobes separated by 1.5 times greatest width of scape. Mouthparts: frontoclypeal margin sparsely pubescent; lacking pubescent fringe; clypeus without pubescence except for few long setae originating at base. Labrum sparsely pubescent, with 8–10 long, suberect, translucent setae.

Thorax: pronotum broadly rounded at sides to posteriorly directed, short, acute tubercles on posterior fourth; constricted along posterior fifth behind lateral tubercles; constriction demarcated with row of large, separate punctures across disc, continuing behind base of tubercles, down sides; pronotum otherwise impunctate except for uniform micropunctures visible only under high magnification. No distinct calli present on disc. Pronotum with uneven vestiture of golden pubescence concentrated at sides of disc, around lateral tubercles, and, often, in two anteromedial spots on disk; elsewhere, pubescence is sparse. Integument mostly light brown, becoming darker at middle of disc, often extending to anteromedial and posteromedial margins. Prosternum smooth, impunctate, covered with uniform, appressed, golden or translucent pubescence. Prosternal process narrow between procoxae (less than one-sixth width) and greatly expanded behind procoxae. Mesosternum smooth, impunctate, covered with uniform, appressed, golden or translucent pubescence. Mesosternal intercoxal process broader than prosternal process, separating mesocoxae by about one-fourth width of mesocoxa. Metasternum smooth, impunctate, covered with uniform, appressed, golden or translucent pubescence. Integument of ventral sclerites mostly light brown, becoming dark brown at sides. Scutellum dark brown with mixture of dark, translucent, and golden pubescence; broadly rounded posteriorly. Elytra: densely, coarsely punctate; coated with moderately dense, appressed pubescence; with mottled light and dark appearance; lacking tubercles and erect setae. Highly variable in distribution of maculae and pubescence, often with a correspondence between integumental color and setal color. Nearly all specimens with very dark brown to black periscutellar region (occasionally extending posteriorly along most of suture). This region often surrounded by lighter brown integument covered in gray or translucent pubescence. Nearly all specimens with an oblique narrow post-medial macula extending from near the sutural margin anterolaterally toward lateral margin (sometimes complete, sometimes extending only one-third to one-half across elytral disk). This black macula bordered by white or gray setae. Humeri slightly projecting anterolaterally, usually with black or very dark macula at base and often poorly-demarcated epipleural region. Elytral apex obliquely truncate; lacking spines. Legs: femora mostly light yellowish-brown with variably sized dark maculae on mesal and lateral face (most pronounced on mesofemora; least pronounced on metafemora); femora mostly uniformly pubescent with combination of fine, appressed, white, translucent, and dark brown setae. Tibiae light yellowish-brown at base, dark brown to piceous at apical half to two-thirds. Tibiae with setae suberect and more stout, particularly. Mesotibiae with dorsal concavity lined with stout, dark, bristle-like setae. Tarsi, with exception of base of first segment, mostly dark brown to piceous on most specimens.

Abdomen: ventrites covered with fine, appressed, golden and translucent pubescence; light brown, becoming darker on basal segments and sides. Fifth ventrite distinctly longer than fourth in both sexes; with weak middle notch fringed by longer setae.

Distribution

This species was originally described from Puerto Rico. We record it from the Dominican Republic (new country record). This is the most widespread and common species on the island of Hispaniola, having been collected at nearly every sampled locality (Fig. 16). We also record this species for Jamaica (new country record) and Navassa Island which lies between Jamaica and Hispaniola. Specific locality data are included for those islands below.

Remarks

Urgleptes sandersoni and Urgleptes haitiensis were each described in Gilmour (1963) on the basis of one specimen; therefore, he was unable to assess intraspecific variation when he defined both species. He stated for U. haitiensis that it differs from U. sandersoni “in being of a general much darker colour and its marmorated appearance”, but shares the pale annulate antennal scape. We have studied hundreds of specimens from Hispaniola and Puerto Rico and found that this is a single, variable species. We demonstrate that the elytral markings vary tremendously (Fig. 9) and without a geographical basis. Figure 9a most closely matches the holotype of U. sandersoni (described from Puerto Rico). Figure 9f most closely matches the holotype of U. haitiensis (described from Haiti). The scape coloration, however, with the presence of the pale apical annulation in an overall darker apical half, is constant for the species as is the elytral punctation and general coloration of the femora, tibiae, and tarsi, described above. We therefore consider U. haitiensis Gilmour (1963: 82) a new synonym of U. sandersoni Gilmour (1963: 79). This species is most similar to U. guadeloupensis (Fleutiaux & Sallé), another highly variable species described from Guadeloupe. According to Gilmour (1963), that species is much paler without a marmorated appearance. Some authors (e.g., Peck 2005) have recorded U. guadeloupensis from the Greater Antilles (Cuba) but other authors (e.g, Micheli 2010) concluded it was not present in Puerto Rico. We agree with Micheli’s concept of U. sandersoni; however, further study and discovery of additional characters may support synonymy of U. sandersoni under U. guadeloupensis.

Urgleptes charynae Ravin & Lingafelter, sp. n.

Figs 3, 8c, 10, 17

Diagnosis

This species is recognized by the mostly uniform, light ferruginous integument covered by mostly uniform pubescence. The elytra have slightly denser patches of white pubescence postmedially extending across the disk (sometimes forming circular patches). Underneath these pubescent patches, the integument is slightly darkened. The pronotum has dense, white pubescence anterolaterally, extending to the lateral tubercles. The only other species with mostly uniform integument color and mostly lacking dense pubescent patches is U. obliteratus. That species is easily distinguished by its much paler integument and typically bold, black, postmedial elytral and pronotal spots. Additionally, U. charynae has the scape uniformly brown, slightly darker apically, unlike other species which usually contain a subapical spot or flavous base.

Urgleptes conjunctus Ravin & Lingafelter, sp. n.

Figs 4, 8f, 11, 18

Diagnosis

The coarsely punctate elytra and narrow longitudinal darkened macula running parallel to the suture make this species readily identifiable. The mesofemora and mesotibiae of this species are distinctly darker than in other species. The antennae are most distinct in that the scape is antemedially darker than the base, and the third and fourth segments contain suberect bristle-like, apicomesal setae. Both the procoxal and mesocoxal processes are very narrow in U. conjunctus and barely separate the coxae.

Urgleptes curtipennis Ravin & Lingafelter, sp. n.

Figs 5, 12, 18

Diagnosis

The proportions of this species are distinctive. The elytra are relatively much shorter compared to overall body length than all other Hispaniolan species. Further, the elytral maculations are well defined and contrast strongly from the dense, ashy, white pubescence that is otherwise present. With the exception of the pedicel and third antennomere being mostly flavous and darkened apically, all remaining antennomeres are gradually darker until the distal segments which are mostly uniform in coloration. Unlike U. sandersoni, U. puertoricensis, and U. conjunctus, this species has a light periscutellar region.

Urgleptes marionae Ravin & Lingafelter, sp. n.

Figs 6, 8g, 13, 19

Diagnosis

The elytra of this species each have an oblique postmedial macula extending anterolaterally from near the suture to middle lateral margin, somewhat similar to U. sandersoni, U. puertoricensis, and U. curtipennis. However U. marionae is unique in that faint, longitudinal, darker maculae are present on the elytra, extending posteriorly from the base, much less defined than in U. conjunctus, and there are three irregular, longitudinal fasciae of pale pubescence. The femora are flavous and densely covered in mostly golden pubescence, with the pro- and mesofemora each containing a medially darkened ring along the dorsal and mesal margins. The mesocoxal process in U. marionae is much broader than in U. conjunctus.

Urgleptes obliteratus Ravin & Lingafelter, sp. n.

Figs 7, 8d, 14, 19

Diagnosis

This species is easily identified by the three dark, circular elytral maculae, originating mediolaterally and extending toward the suture. This dark circular pattern is repeated on the pronotum which usually contains two posteromedial spots, in some specimens, an additional two are located at the base of the lateral tubercles. The elytral suture is narrowly dark brown. Otherwise, the integument is mostly uniform in color, although in U. obliteratus it is much paler yellow or flavous than in U. charynae. Unlike other species, the scape is uniformly pale, with antennomeres light, gradually becoming darker at apices. The femora are also mostly pale, with the tibiae usually darker postmedially.

Head: covered in uniform pale to golden pubescence, denser at posterior margin of eyes and inner eye notch margin. Antenna: scape extending to posterior fourth of pronotum; pale-flavous, weakly darker apically; covered in fine, pale to golden pubescence. Remaining antennomeres pallid, darkened apically; covered in brown pubescence, with thickened bristle-like setae at apices; mesal surface of third and fourth segments of most specimens usually with thickened setae. Antennae extending beyond elytral apices by approximately five segments. Eye: lower eye lobe about 2.5 times height of upper eye lobe; lobes narrowly connected by about 5 rows of ommatidia in most specimens. Upper eye lobes separated by twice width of upper eye lobe. Mouthparts: clypeus pallid; lacking distinct pubescence. Labrum pallid; anteriorly fringed with long, golden setae; and basal, longer, suberect, dark brown setae. Mandibles light brown, distinctly darkened on apical halves.

Thorax: pronotum broadly rounded at sides to posteriorly directed, short, acute tubercles on posterior fourth; constricted along posterior fifth behind lateral tubercles; constriction demarcated with row of large, separate punctures across disc, continuing behind base of tubercles and down sides; no other distinct punctures visible. Integument mostly light brown; coated in moderately dense vestiture of white pubescence. Pronotal disc with dark anterolateral and posteromedial fasciae. No distinct calli present on pronotal disc. Prosternum impunctate; covered in moderately dense white pubescence. Prosternal process extremely narrow and greatly expanded posteriorly; procoxal cavities nearly touching. Mesepimeron toward metepisternal margin coated with dense, appressed, white pubescence becoming thinner ventrally. Mesosternal intercoxal process about 3–4 times broader than prosternal process. Integument of ventral sclerites mostly light brown, with margins of coxal cavities darkened. Scutellum dark brown; with white, longitudinal fascia. Elytra: moderately, densely punctate; elytral disc mostly pale-orange with suture dark brown from scutellum to apices. Periscutellar region slightly swollen; coated in white to translucent pubescence extending throughout disc; epipleuron slightly darker than surrounding region. Elytron with three, dark, distinct, circular maculae, originating mediolaterally, obliquely extending toward, but not reaching suture. Some specimens with faint, irregular macula extending anteriorly from apex but not reaching circular maculae. Elytral apex subtruncate, with outer apical angle slightly more produced posteriorly than sutural angle. Legs: femora mostly pallid; uniformly covered with golden to translucent pubescence. Protibiae uniformly pallid; meso- and metatibiae darker apically with thickened, bristle-like setae. Mesotibiae with dorsal concavity apically that is lined with dark, bristle-like setae. Tarsomeres dark brown; coated with long, suberect, dark setae.

Abdomen: ventrites covered with fine, appressed, white pubescence; integument mottled brown, posteriorly lighter, apical margin of all ventrites slightly lighter. Fifth ventrite one and a half times longer than fourth. Last tergite strongly narrowed and projecting beyond last ventrite.

Distribution

Endemic to Hispaniola, this species has been collected only in low elevation (less than 700 meters) coastal areas of the country (Fig. 19) from May through December.

Etymology

The epithet, obliteratus, refers to the nearly absent maculae on the elytra, unlike most other species of the genus.
