Integument black except yellowish-orange as follows, basal area of mandible, pronotum, mesonotum, subalar lobe, tegula, metasoma, femora, basal area of hind tibia, anterior and middle tibia and tarsomeres; mandible apex, basal area of hind tibia; tarsomeres blackish; wing veins dark brown; forewing infumate with a hyaline spot on the first submarginal cell that is similar in size to the parastigma. Specimens range from black to yellowish - orange on the head, propleuron, metanotum, propodeum, mesopleuron, metapleuron and hind coxa. Head (Fig. 1ab).

Mesosoma (Fig. 1 c–f). Pronotum smooth; lateral pronotal margins with weakly crenulate groove; notauli impressed; anterolateral edges of scutellum with a small acute projection; scutellar disc convex with sparse setae from 0.16 to 0.17 mm in length; scutellar disc sloped posteriorly and rounded; lateral scutellar depression rugose and foveolate; carinae of central metanotal area forming a triangular cell; propodeum reticulate rugose, more pronounced on lateral margins; subalar lobe separated from mesopleuron by narrow rugulose groove, width distinctly of shorter than subalar lobe; metapleuron rugose with reticulate-foveolae. Legs. Inner spur of middle tibia 0.76 –0.83× length of basitarsus; inner spur of hind tibia 0.59 –0.69× length of basitarsus; metabasitarsus 1.18 –1.25× length of tarsomeres III, IV, and V combined; hind tibia 2.00 –2.21× longer than basitarsus; hind femur length 3.38 –4.12× its maximum width. Wings. Forewing length/width = 2.46-2.51; stigma 2.69 –3.50× longer than maximum width; forewing vein R1 0.60 –0.66× as long as vein RS; vein RS sinuate; vein r arising slightly before middle of stigma; second submarginal cell triangular, with petiole 0.07-0.13 mm long; vein M+CU distinctly pigmented throughout; hind wing length/width = 3.37-3.52; hind wing vein 1M 1.65 –1.80× longer than 1r-m; hind wing with 4-5 hamuli. Metasoma. Apical width of petiole (tergum 1) 2.90 –3.21× wider than basal width; minimum width of petiole 0.58 –0.60× apical width; length of ovipositor sheath 0.17-0.30 mm.

Male.

Similar to female.

Host.

Unknown.

Distribution.

Canada, Mexico, and USA.

Diagnosis.

Distinguished from other Crassomicrodus species by the following combination of characters: area between antennal sockets with a median transverse elevation, anterolateral edges of scutellum with a small acute projection, groove between lateral ocelli with small foveolae, and head and mesosoma black with some areas yellowish-orange.

Remark.

This species is near to Crassomicrodus nigrithorax , but differs in that Crassomicrodus nigrithorax has the mesosoma black; anterolateral edges of scutellum lacking small acute projection; eye height 0.69 –0.70× inter-ocular distance; malar space 0.38 –0.47× longer than eye height; inner spur of middle tibia 0.89 –0.95× length of basitarsus; and scutellar disc convex with sparse setae from 0.14 to 0.15 mm in length.
