Heerz lukenatcha Marsh

Heerz distinguishes from other doryctine genera by the following combination of features: (1) frons excavated (Fig. 2D), (2) propodeum with a longitudinal median carina followed by a pentagonal areola (Figs 2C, 3D), (3) second metasomal tergite entirely or partially sculptured, contrasting with third one, which is smooth, polished and with a transverse furrow (Figs 2C, 3D), (4) vein r-m of fore wing present (Fig. 2F), (5) vein M+CU of hind about as long as vein 1M, (6) vein cu-a of hind wing straight or slightly curved apically towards wing apex, (7) male hind wing without pterostigma, and (8) hind coxa with a distinct basoventral tooth. Species of Heerz are very similar in habitus to those of Lissopsius, all having a body mostly smooth and shiny, propodeum with a longitudinal median carina followed by a pentagonal areola, and vein M+CU of hind wing slightly shorter to larger than vein 1M. However, Heerz differs from Lissopsius by having the vein r-m of fore wing present (Fig. 2F) (absent in Lissopsius), hind coxa with a basoventral tooth (absent in Lissopsius), and ovipositor distinctly sclerotised apically (uniformly slcerotised in Lissopsius).

Brazil, Costa Rica and Mexico.

The two new species of Heerz described below considerably modify the previous concept of the genus. The two previously described species, Heerz lukenatcha and Heerz tooya Marsh, are characterised by their smooth mesosoma, dusky wings and relatively large body size. The Mexican species, on the other hand, have a coriaceous mesoscutum, uniformly hyaline wings and are considerably smaller, especially Heerz ecmahla. Moreover, frons excavation is more conspicuous in the two new species compared to Heerz lukenatcha and Heerz tooya. Despite these morphological differences, our comparisons with type material and our DNA sequence data (see below) led us to include the new species within Heerz.

Heerz ecmahla distinguishes from the remaining species of the genus by the uniformly coriaceous sculpture on the first and second metasomal tergites (Fig. 2C). It also distinguishes from the Central and South American species, Heerz tooya and Heerz lukenatcha, by its entirely hyaline wings (Fig. 2A) [wings partially or totally infuscate in the latter two species (Fig. 2B)], and from Heerz macrophtalma by its relatively smaller eyes (Fig. 2D) [considerably large in Heerz macrophtalma (Fig. 3B)] and distinctly longer ovipositor (Fig. 2A) [about 0.5 times as long as metasoma in Heerz macrophtalma (Fig. 3A)].

The specific epithet is an anagram of Chamela, the type locality of this species.

Heerz macrophthalma distinguishes from the remaining species of the genus by its considerably larger eyes (Fig. 3B).

Lissopsius flavus Marsh, 2002.

This genus distinguishes from other recognised doryctine genera by the following combination of features: (1) body mostly smooth and polished (Figs 4A-E, 5B-F), (2) propodeum with a median longitudinal carina followed by a pentagonal areola (Figs 4B, 5D), (3) vein r-m of fore wing absent (Fig. 4F), (4) vein M+CU of hind wing larger than vein 1M (Fig. 4F), (5) vein cu-a of hind wing curved at apex towards wing tip (Fig. 4F), (6) hind coxa angled at base, without distinct tubercle or tooth, and (7) ovipositor uniformly sclerotised and with a single nodus (Fig. 4G). Lissopsius is closely related to Heerz (see above) and both are morphologically similar, with a body mostly smooth and polished, propodeal areola present and vein M+CU of hind wing slightly shorter to longer than vein 1M. However, Lissopsius differs from Heerz by having the vein r-m of fore wing absent (always present in Heerz), hind coxa without basoventral tooth (present in Heerz), and ovipositor uniformly sclerotised (strongly sclerotised at apex in Heerz).

Small size, 2.3-4.5 mm; eyes large, emarginated opposite antennal sockets; occipital carina present, ending before reaching hypostomal carina; labrum distinctly concave; hypoclypeal depression small and round; clypeus short; malar suture absent; maxillary palpi 5-segmented, labial palpi 4-segmented; head, mesosoma and metasoma mostly smooth and polished; mesoscutum declivous anteriorly; prepectal carinae present; precoxal sulcus shallow and almost indistinct; surface of propodeum smooth on anterior half, slightly rugose on posterior half, with median longitudinal carina anteriorly and pentagonal areola posteriorly; metapleural flange present; fore tibia with a row of at least 10 spines along anterior edge (Fig. 4H); hind coxa angled at base, without basoventral tooth; vein m-cu of fore wing considerably antefurcal to vein 2RS, vein (RS+M)b present; vein 1cu-a considerably postfurcal to vein 1M; vein r-m of fore wing absent; first subdiscal cell of fore wing open at apex; vein M+CU of hind wing equal to or slightly longer than vein 1M; males without stigma-like enlargement on hind wing; basal sternal plate (acrosternite) of first metasomal tergite about 0.25 length of tergite.

Costa Rica and Mexico.

In their study describing new ovipositor diagnostic features for the subfamily Doryctinae, Quicke et al. (1995) proposed two potential morphological synapomorphies for the group: the presence of a double nodus on the dorsal valve of the ovipositor and a strongly sclerotised apex. These characters, however, despite being present in most doryctines, have apparently been reduced or lost in species of various genera (Quicke et al. 1995), including the two of the species of Heerz described here (a single or lack of nodus) and the three described known species of Lissopsius (uniformly sclerotized apex). The two new species described below represent the first records of the genus outside Costa Rica, and therefore for the Mexican territory. All the specimens of Lissopsius included in this work were only collected with light traps, and most of them were collected during three nights in June 2009 and belong to Lissopsius pacificus sp. n. The colour of the body in the sequenced specimens of the two species of Lissopsius described here became slightly darker after carrying out their DNA extractions, since we used the whole individuals and a non-destructive DNA extraction technique.

This new species distinguishes from Lissopsius jaliscoensissp. n.and Lissopsius flavus in having a second metasomal tergite mostly smooth, only slightly costate basally (Fig. 4E) [distinctly costate basally, remaining area smooth in Lissopsius flavus; distinctly costate basomedially, remaining area smooth in Lissopsius jaliscoensissp. n.(Fig. 5F)]; ventral part of mesopleuron, precoxal sulcus and venter of mesosoma darker that the rest of the body (Fig. 4A) [mesosoma completely yellow in Lissopsius flavus and Lissopsius jaliscoensis (Figs 5A, B)]; and notauli ending before first half of mesoscutum (Fig. 4B) [ending after first half of mesoscutum in Lissopsius flavus and Lissopsius jaliscoensissp. n. (Figs 5B, D)]. Lissospius pacificus also distinguishes from Lissopsius flavus in having a very short ovipositor, about 0.25 times as long as metasoma (Fig. 4A, G) [ovipositor as long as metasoma in Lissopsius flavus (Fig. 5A)]; a triangular, longitudinally rugose area in the posteromedian area of mesoscutum (Fig. 4B) [smooth in Lissopsius flavus (Fig. 5B)]; and smooth third metasomal tergite (Fig. 4E) (third metasomal tergite smooth with weak transverse scrobiculate groove apically in Lissopsius flavus).

Female. Colour: head yellow, ventral part of mesopleuron, precoxal sulcus and venter of mesosoma light brown, remainder part of mesosoma yellow; metasoma yellow with some areas light brown; pedicel and flagellum yellow to light brown; legs yellow, hind tarsi light brown; wings hyaline, veins and pterostigma brown, tegula yellow. Body length: 3.4 mm. Head: entirely smooth, vertex and temple pilose, face strongly pilose; eyes large, malar space about 0.2 times eye height; ocello-ocular distance about 1.5 times diameter of lateral ocellus; eye 1.2 times higher than wide (lateral view); antennae broken, with at least 20 flagellomeres; scape with the same length as first flagellomere; first flagellomere longer than second. Mesosoma: length of mesosoma 1.7 times its maximum height; pronotum smooth dorsally, slightly rugose ventrally, pronotal groove slightly scrobiculate; mesoscutal lobes smooth, sparsely pilose medially, with a triangular longitudinal rugose area in the posteromedian area of mesoscutum; notauli deep and scrobiculate, not joining, ending before anterior half of mesoscutum; posterolateral sides of scutellum rugose, remaining areas smooth; scutellar sulcus deep and scrobiculate, with five longitudinal carinae; mesopleuron smooth, posterior mesopleural sulcus distinct and scrobiculate, subalar groove puctate; precoxal sulcus shallow and smooth, ending on anterior half of mesopleuron; metapleuron smooth, propodeum smooth on basal half, slightly rugose on apical half, with a median longitudinal carina followed by a distinct pentagonal areola. Legs: hind coxa smooth, protruding forward in ventro-anterior corner, about 1.4 times longer than its maximum width. Wings: Fore wing length 3.2 times its maximum width, length of pterostigma 2.9 times its maximum width, vein m-cu clearly antefurcal to vein 2RS, vein 1cu-a clearly postfurcal to vein 1M; hind wing vein M+CU 1.4 times longer than vein 1M; vein cu-a curved at apex toward wing tip. Metasoma: first metasomal tergite short, about 0.8 times as long as its apical width, medially smooth, laterally slightly costate-punctate; second metasomal tergite slightly costate basally, remaining area smooth; suture between second and third metasomal tergites poorly defined; remaining metasomal tergites smooth and polished; ovipositor very short, about 0.3 times length of metasoma.

The two new species of Lissopsius described in this study apparently have nocturnal habits, since all their specimens were only collected with light traps. These species appear to be generalist parasitoids of various species of lepidopterans according to an ongoing study (Zaldívar-Riverón et al. in prep.) that is being carried out based on molecular analyses of parasitoid linkages (MAPL; Rougerie et al. 2010).

The specific name refers to the area where the species was collected, which is situated near the Mexican Pacific coast.

This species distinguishes from Lissopsius pacificus and Lissopsius flavus by having the second metasomal tergite distinctly costate basomedially (Fig. 5F) [mostly smooth, only slightly costate basally in Lissopsius pacificus (Fig. 4D); distinctly costate basally, remaining area smooth in Lissopsius flavus]. Lissopsius jaliscoensis is morphologically very similar to Lissopsius pacificus, but differs from this species by having the mesosoma entirely yellow (Fig. 5C) [ventral part of mesopleuron, precoxal sulcus and venter of mesosoma darker that the rest of the body in Lissopsius pacificus (Fig. 4A)], and notauli ending after first half of mesoscutum (Fig. 5D) [ending before first half of mesoscutum in Lissopsius pacificus (Fig. 4B)].

Ondigus bicolor Braet, Barbalho & van Achterberg

This genus distinguishes from the remaining doryctine genera by having the following combination of features: (1) first six metasomal tergites sculptured, fourth to sixth granulate (Figs 6B, F); (2) suture between the second and third metasomal tergites wide, deep, scrobiculate and slightly sinuate (Figs 6B, F); (3) third metasomal tergite with a deep, scrobiculate transverse groove (Figs 6B, F); (4) first subdiscal cell of fore wing open at apex (Figs 6E, G); (5) hind coxa with a distinct basoventral tooth; hind wing vein M+CU approximately the same length of vein 1M (Figs 6E, G); (6) all femora with subbasal tubercles (Fig. 6A).

Moderate size, female 5.6–6.1 mm, male 4.2 mm; eyes large, moderately emarginated opposite antennal sockets; maxillary palpi 5-segmented, labial palpi 4-segmented; face densely setose; occipital carina present and complete; hypoclypeal depression elliptic; clypeus short and wide; malar suture absent; mesosoma setose and mostly coriaceous; mesoscutum declivous anteriorly; notauli distinct anteriorly, scrobiculate, obscured at half of mesoscutum in a longitudinally rugose area; prepectal carinae present; metapleural flange present; all femora with a subbasal protuberance; fore tibia with a row six to eight spines along anterior edge; hind coxa granulate, pilose, with a basoventral tooth; only known male with pterostigma on hind wing; vein m-cu of fore wing interstitial or slightly antefurcal to vein 2RS; vein 1cu-a considerably postfurcal to vein 1M; vein r-m of fore wing present; second submarginal cell of fore wing long; first subdiscal cell of fore wing open at apex; hind wing vein M+CU equal to or slightly longer than vein 1M; first metasomal tergite about 1.1–1.2 times longer than its apical width; suture between second and third metasomal tergite wide, deep, scrobiculate and slightly sinuate; third metasomal tergite with a deep, scrobiculate transverse groove; basal sternal plate (acrosternite) of first metasomal tergite about 0.2 length of tergum.

French Guyana, Mexico.

The new species of Ondigus described here differs in some of the morphological features originally proposed by Braet et al. (2003) to define the genus. These features include a striate vertex, propodeum without longitudinal median carinae and areola, and second metasomal tergite without a pair of sublateral depressions. The above species and Ondigus bicolor, however, share a number of diagnostic features on wing venation, legs and sculpture of metasomal tergites. The majority rule consensus tree derived from the Bayesian analysis performed recovered Ondigus bicolor and our new species in separate clades; the relationships involved, however, were weakly supported. Based on the above morphological similarities and the unclear phylogenetic relationships obtained, we have decided to place the new species within Ondigus until additional help us to confirm the conspecificity of the taxa involved.

This species differs from the other described species of the genus, Ondigus bicolor by having a vertex striate (smooth in Ondigus bicolor), propodeum without a median longitudinal carina and areola (Fig. 6C) [both present in Ondigus bicolor (Fig. 6F)], dorsolateral carinae of first metasomal tergite ending before its anterior half (Fig. 6B) [running through the apical end of first metasomal tergite in Ondigus bicolor (Fig. 6F)], and second metasomal tergite without a pair of sublateral depressions (Fig. 6B) [present in Ondigus bicolor (Fig. 6F)].

Female. Colour: head and mesosoma dark brown, eye orbits honey yellow; scape and pedicel brown, flagellomeres brown, turning black to apex; palpi pale yellow; first metasomal tergite dark brown, with a semicircular area yellow apically; remaining metasomal tergites yellow, with brown irregular areas laterally; fore, middle and hind coxae, trochanter and trochantellus pale yellow, femora and tibiae pale yellow with irregular specks medially and apically, tarsi light brown to brown; wings hyaline, veins and pterostigma light brown, tegula pale yellow. Body length: 5.6 mm; ovipositor 2.5 mm. Head: face, frons and vertex striate, temple and gena smooth; malar space about 0.2 times eye height; occipital carina ending just before reaching hypostomal carina; ocello-ocular distance about the same length than diameter of lateral ocellus; eye 1.2 times higher than wide (lateral view); antennae broken, with at least 31 flagellomeres; scape longer than first flagellomere; first flagellomere longer than second. Mesosoma: length of mesosoma about 2.0 times its maximum height; pronotum rugose dorsally and ventrally, pronotal groove scrobiculate; mesoscutal lobes coriaceous, slightly transversally rugose at the edges of notauli; notauli deep and scrobiculate, joining before mesoscutum in a rugose area; scutellar disc coriaceous; scutellar sulcus large, deep and scrobiculate, interrupted by scutellar disc, with at least nine longitudinal carinae on each side; mesopleuron porcate-coriaceous dorsally, coriaceous medially and ventrally; precoxal sulcus complete, wide, deep and scrobiculate; venter of mesopleuron coriaceous; posterior mesopleural sulcus narrow and scrobiculate; metapleuron rugose-areolate with coriaceous microsculpture, propodeum longitudinally rugose with coriaceous microsculpture, with a median longitudinal carina on apical half. Legs: hind coxa, femur and tibia coriaceous, about 1.4 times longer than its maximum width. Wings: Fore wing length 3.7 times its maximum width, length of pterostigma 2.7 times its maximum width, vein m-cu interstitial to vein 2RS, vein 1cu-a clearly postfurcal to vein 1M; hind wing vein M+CU about the same length as vein 1M. Metasoma: first metasomal tergite about the same length as its apical width, costate with rugose microsculpture, with dorsolateral carinae ending before its anterior half; second metasomal tergite costate with rugose microsculpture; third metasomal tergite longitudinally striate with granulose microsculpture, with a deep, wide and scrobiculate transversal groove basally; suture between third and fourth metasomal tergites wide, deep, scrobiculate and sinuate; fourth metasomal tergite granulate with basal longitudinal striae; fifth to seventh metasomal tergites granulate, remaining ones smooth; ovipositor long, about 1.7 times length of metasoma.

Male. Smaller than female, body length 4.2 mm; vertex dark brown, rest of head honey yellow; mesopleuron and dorsal and lateral areas of pronotum dark brown to black, remaining part of mesosoma and basal two thirds of first metasomal tergite brown; 30 flagellomeres (complete); vein m-cu antefurcal to vein 2RS; hind wing with stigma; suture between second and third metasomal tergites straight.
