Colocistis pilosa Krombein 1942

Calif. (San Diego).

Male (Figs 27, 28). Body length 11–12 mm. Head (Fig. 7). Compound eyes not enlarged, barely extending beyond temples, inner margins slightly evenly curved; ocelli small, diameter of lateral ocellus 0.5× OOL; without impressed line between lateral ocelli; antennal socket rim slightly thickened ventrolaterally; clypeus with median tubercle visible in lateral view, apex bounded laterally by strong teeth; gular carina not raised; LID 0.85× UID; flagellomere I length 2.4× breadth; flagellomeres II-X missing; occipital carina strong but incomplete ventrally, with carina extending from foramen magnum to hypostomal carina medially; mandible narrowest submedially. Mesosoma. Pronotum nearly vertical anteriorly, sloping posteriorly, punctures deep, largely contiguous, shoulders well-developed, not produced laterally; forefemur without stout spines; foretibia without spines, except apically; basitarsus with three spines on outer surface; tibial spur 0.9× length of basitarsus; hindcoxa without longitudinal dorsal carina tooth-like basally; mesonotal and mesopleural punctures contiguous; scutellum strongly arched dorsally much above level of propodeum, punctures 0.5–1.5 puncture diameters apart, with small, polished impunctate area medially; postscutellum punctures large, contiguous; propodeum dorsal surface coarsely rugulose, separated from posterior face by distinct carina, posterior face punctures contiguous laterally, becoming more widely separated toward midline, except for small dorsomedial impunctate area, punctures becoming small toward petiole, laterally punctures 0.5 puncture diameter apart to contiguous; forewing with 3 submarginal cells, costa extending along wing margin beyond stigma. Metasoma. Tergum I without transverse carina; sternum II with anterior portion slightly raised and separated from remainder of sternum by transverse declivity. Genitalia (Figs 47, 55). Gonostylus slightly emarginate ventrally before tip in lateral view; aedeagus evenly curved, simple at apex in lateral view. Color. Head and body unicolorous, black, with extensive long, erect pale, yellowish setae, setae more than half as long as eye height. Female unknown.
