Crassomicrodus costaricensis Figueroa, Sharkey and Romero ZBK sp. n. Fig. 4 a–e
Description female.
Body. Length. 8.10-8.70 mm. Color (Fig. 4e). Integument black except eye silver, ocelli translucent yellow (Fig. 1d); medial area of mandible yellow-reddish; metasoma dark brown; forewing strongly infumate with a hyaline spot on the first submarginal cell that is similar in size to the parastigma. Head (Fig. 4ab). Triangular in frontal view; face with longitudinal ridge dorsomedially; eye height/width = 1.41-1.42; eye height (lateral view) 0.75 –0.77× inter-ocular distance (anterior view); area between antennal sockets with a median pyramidal-shaped elevation; frons excavated with a little longitudinal groove; posterior surface of antennal sockets smooth; groove between lateral ocelli smooth; median ocellus separated from lateral ocellus by smooth groove; gena not bulging; malar space 0.47 –0.51× as long as eye height; clypeus 2.13 –2.32× wider than high; length of ventrolateral margin of clypeus similar to diameter of tentorial pit; antenna with 41 flagellomeres; setae at base of mandible distinctly longer than setae on rest of body surface. Mesosoma (Fig. 4cde). 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 0.12 to 0.14 mm in length; scutellar disc sloped posteriorly and rounded; lateral scutellar depression smooth with punctures or rugosities in its ventral border; carinae of central metanotal area almost circular shaped; propodeum reticulate rugulose, more pronounced on lateral margins; subalar lobe separated from mesopleuron by wide rugulose groove, width almost of similar size to subalar lobe; metapleuron smooth, only reticulate rugulose one-fourth of ventral area. Legs. Inner spur of middle tibia 0.76 –0.89× length of basitarsus; inner spur of hind tibia 0.62 –0.72× length of basitarsus; metabasitarsus 1.02 –1.18× length of tarsomeres III, IV, and V combined; hind tibia 2.04 –2.38× longer than basitarsus; hind femur length 4.07 –4.17× its maximum width. Wings. Forewing length/width = 2.58; stigma 4.54 –5.00× longer than maximum width; forewing vein R1 0.60 –0.64× as long as vein RS; vein RS sinuate; vein r arising before middle of stigma; second submarginal cell triangular, with petiole 0.13-0.20 mm long; vein M+CU distinctly pigmented throughout; hind wing length/width = 3.48-3.65; hind wing vein 1M 1.01 –1.08× longer than 1r-m; hind wing with 6-7 hamuli. Metasoma. Apical width of petiole (tergum 1) 2.86 –2.91× wider than basal width; minimum width of petiole 0.49 –0.59× apical width; length of ovipositor sheath 0.28-0.41 mm.

Distribution.
Costa Rica and El Salvador.
Diagnosis.
Distinguished from other Crassomicrodus species by the following combination of characters: area between antennal sockets with a median pyramidal-shaped elevation, eye height 0.75 –0.77× inter-ocular distance, antenna with 41 flagellomeres, body length 8.10 to 8.70 mm, hind wing vein 1M 1.01 –1.08× longer than 1r-m, head and mesosoma black, metasoma dark brown, and wings strongly infumate.
Remark.
Specimens from Costa Rica are homogeneous in their measurements, but the specimen from El Salvador differs significantly. Nonetheless it is considered conspecific here due to similarity in other characters. More specimens and molecular data should easily test this hypothesis in the future.
Etymology.
The specific name is a noun in apposition to Crassomicrodus and is chosen because of the locality where the holotype was collected, Costa Rica.
