Crassomicrodus oaxaquensis Figueroa, Romero & Sharkey ZBK sp. n. Fig. 12 a–e
Description female.
Body. Length. 7.10-7.65 mm. Color (Fig. 12e). Integument black except yellowish-orange as follows, ocelli, fore tibia, two-thirds apical areas of fore and middle femur, two-thirds basal areas of middle tibia and metasoma; medial area of mandible yellow reddish; eyes silver; wing veins dark brown; forewing almost hyaline. Sometimes first metasomal tergite black, and the yellowish-orange of legs is reduced to only the apical area of fore and middle femora and apical area of fore tibia. Head (Fig. 12ab). Triangular in frontal view; face with weak longitudinal ridge dorsomedially; eye height/width = 1.34-1.45; eye height 0.60 –0.62× inter-ocular distance; area between antennal sockets with a median pyramidal-shaped elevation and two weakly defined tubercles; frons excavated with a pair of microfoveolate grooves that diverge towards the ocellar area; posterior surface of antennal sockets rugulose; groove between lateral ocelli smooth; median ocellus separated from lateral ocellus by smooth groove; gena not bulging; malar space 0.55 –0.58× as long as eye height; clypeus 2.25 –2.44× wider than high; length of ventrolateral margin of clypeus almost similar to diameter of tentorial pit; antenna with 38-39 flagellomeres; setae at base of mandible slightly longer than setae on rest of body surface; face very setose. Mesosoma (Fig. 12cde). Pronotum punctate; lateral pronotal margins with weakly crenulate groove; notauli impressed; anterolateral edges of scutellum lacking small acute projection; scutellar disc slightly convex with sparse setae from 0.15 to 0.16 mm in length; scutellar disc sloped posteriorly and rounded; lateral scutellar depression rugulose and punctate; carinae of central metanotal area forming a triangular cell; propodeum reticulate rugulose with abundant sparse setae on lateral areas; subalar lobe separated from mesopleuron by wide rugose groove, width almost of similar size to subalar lobe; metapleuron reticulate rugulose in its ventral half and smooth or punctuate in its dorsal half. Legs. Inner spur of middle tibia 0.68 –0.73× length of basitarsus; inner spur of hind tibia 0.58 –0.66× length of basitarsus; metabasitarsus 1.25 –1.32× length of tarsomeres III, IV, and V combined; hind tibia 2.33 –2.38× longer than basitarsus; hind femur length 4.64 –4.76× its maximum width. Wings. Forewing length/width = 2.57-2.76; stigma 2.91 –3.33× longer than maximum width; forewing vein R1 0.65 –0.70× as long as vein RS; vein RS sinuate; vein r arising before middle of stigma; second submarginal cell triangular, with petiole 0.08-0.09 mm long; vein M+CU distinctly pigmented throughout; hind wing length/width = 3.70-3.73; hind wing vein 1M 1.79 –1.82× longer than 1r-m; hind wing with 5 hamuli. Metasoma. Apical width of petiole (tergum 1) 3.00 –3.41× wider than basal width; minimum width of petiole 0.46 –0.47× apical width; length of ovipositor sheath 0.22-0.26 mm.
Male.
Similar to female except metasomal tergite has the color dark brown, antenna with 39 or 40 flagellomeres, and hind wing with 4 or 5 hamuli.
Host.
Unknown.
Distribution.
Mexico.
Diagnosis.
Distinguished from other Crassomicrodus species by the following combination of characters: area between antennal sockets with a median pyramidal-shaped elevation, head triangular in frontal view, posterior surface of antennal sockets rugulose, face very setose, setae at base of mandible slightly longer than setae on rest of body surface, subalar lobe separated from mesopleuron by wide rugose groove, head and mesosoma black, and wings almost hyaline.
Remarks.
This species is near to Crassomicrodus jalisciensis , but differs in that Crassomicrodus jalisciensis has areas of mesosoma yellowish orange, wings infumate, face without longitudinal ridge dorsomedially, and a median elevation between antennal sockets without defined lateral tubercles.
Etymology.
Crassomicrodus oaxaquensis is after Oaxaca, in reference to the known geographical distribution of the species.
