Crassomicrodus azteca Figueroa, Romero & Sharkey sp. n. Fig. 2 a–d

Description female.

Body. Length. 5.20-5.50 mm. Color (Fig. 2d). Integument black except yellowish-orange as follows, medial area of mandible, tegula, femora, anterior and middle tibiae and tarsomeres, and metasoma; eyes silver; ocelli translucent honey yellow; wing veins dark brown; forewing slightly infumate with a hyaline spot on the first submarginal cell that is similar in size to the parastigma. In some specimens the first metasomal tergite blackish. Head (Fig. 2ab). Triangular in frontal view; face with weak longitudinal ridge dorsomedially; eye height/width = 1.43-1.45; eye height 0.59 –0.63× inter-ocular distance; area between antennal sockets with a median pyramidal-shaped elevation; frons excavated with a pair of microfoveolate grooves that diverge towards the ocellar area; posterior surface of antennal sockets slightly rugulose; groove between lateral ocelli smooth; median ocellus separated from lateral ocellus by smooth groove; gena not bulging; malar space 0.60 –0.63× as long as eye height; clypeus 2.27 –2.35× wider than high; length of ventrolateral margin of clypeus similar to diameter of tentorial pit; antenna with 31-33 flagellomeres; setae at base of mandible slightly longer than setae on rest of body surface. Mesosoma (Fig. 2bcd). Pronotum punctulate with setae; lateral pronotal margins with a shallow, crenulate groove; notauli impressed; anterolateral edges of scutellum lacking small acute projection; scutellar disc convex with sparse setae from 0.13 to 0.14 mm in length; scutellar disc sloped posteriorly and rounded; lateral scutellar depression smooth, sometimes with microfoveolate grooves in its ventral and dorsal margins; carinae of central metanotal area almost circular shaped, sometimes triangular; propodeum reticulate rugose with abundant setae in its lateral areas; subalar lobe separated from mesopleuron by narrow rugulose groove, width distinctly of smaller size than the subalar lobe; metapleuron reticulate rugulose in its ventral half and smooth in its dorsal half. Legs. Inner spur of middle tibia 0.65 –0.70× length of basitarsus; inner spur of hind tibia 0.58 –0.64× length of basitarsus; metabasitarsus 1.05 –1.16× length of tarsomeres III, IV, and V combined; hind tibia 2.41 –2.67× longer than basitarsus; hind femur length 3.50 –4.00× its maximum width. Wings. Forewing length/width = 2.50-2.55; stigma 3.00 –3.23× longer than maximum width; forewing vein R1 0.61 –0.68× as long as vein RS; vein RS slightly straight; vein r arising before middle of stigma; second submarginal cell triangular, with petiole 0.07-0.12 mm long; vein M+CU weakly pigmented in 0.75 of its basal length; hind wing length/width = 3.37-3.38; hind wing vein 1M 1.44 –1.70× longer than 1r-m; hind wing with 4-5 hamuli. Metasoma. Apical width of petiole (tergum 1) 3.46 –3.71× wider than basal width; minimum width of petiole 0.53 –0.59× apical width; length of ovipositor sheath 0.13-0.28 mm.

Male.

Similar to female, but the posterior surface of antennal sockets smooth.

Host.

Copitarsia sp. ( Lepidoptera : Noctuidae ) in Brassica oleraceae L. (cauliflower).

Distribution.

Mexico.

Diagnosis.

Distinguished from other Crassomicrodus species by the following combination of characters: area between antennal sockets with a median pyramidal-shaped elevation, malar space 0.60 –0.63× as long as eye height, setae at base of mandible slightly longer than setae on rest of body surface, body length 5.20-5.50 mm, head and mesosoma black, and forewing slightly infumate.

Remarks.

This species is similar to Crassomicrodus nigrithorax , but differs in that Crassomicrodus nigrithorax has gena bulging; area between antennal sockets with a median transverse elevation; groove between lateral ocelli with small foveolae; and malar space 0.38 –0.47× longer than eye height.

Etymology.

The specific epithet is a noun in apposition to Crassomicrodus , which is reference to some of the indigenous people of Mexico.
