This is one of three species, including Colocistis castanea and Colocistis oaxacana, which have three submarginal cells and the second metasomal sternum simple. It can be distinguished from both by the tuberculate clypeus.
Description. Male.
Body length. 8–15 mm.
Head (Fig. 8). Compound eyes enlarged, extending well beyond temples; ocelli enlarged, diameter of lateral ocellus at least 0.7× OOL; impressed line present between lateral ocelli; antennal socket rim only slightly thickened ventrolaterally; clypeus with median tubercle visible above mandible in lateral view, apex not bounded laterally by strong teeth; gular carina not raised; LID 0.7× UID; flagellomeres I-II length 2.3–2.4× breadth; flagellomere IX length 5× breadth; occipital carina strong but, complete ventrally; hypostomal carina not raised; mandible narrowest submedially, apically broad and teeth subequal in length.
Mesosoma. Pronotum nearly vertical anteriorly, punctures deep, 0.5 puncture diameter apart to contiguous, shoulders well-developed, not produced laterally; forefemur without stout spines; foretibia without spines except apically; basitarsus with two spines on outer surface; tibial spur 0.9× length of basitarsus; hindcoxa without basally tooth-like longitudinal dorsal carina; scutal punctures 0.5–2.0 puncture diameters apart; mesopleural punctures contiguous; scutellum flattened dorsally nearly planar with level of propodeum, punctures 0.5–1.0 puncture diameters apart, with small, polished impunctate area medially; postscutellum densely punctate; propodeal dorsal surface separated from posterior and lateral surfaces by carina, dorsal surface with longitudinal medial trough, surface shallowly rugose, posterior surface nearly impunctate, lateral surface densely punctate dorsally, impunctate ventrally; forewing with 3 submarginal cells; costa extending along wing beyond stigma.
Metasoma. Tergum I without transverse carina; sternum II without raised area basally.
Genitalia (Figs 48, 56). gonostylar apex nearly straight in lateral view; aedeagus abruptly decurved before apex, without dorsally projecting process.
Color. Head and body unicolorous, castaneous; vestiture whitish to pale yellow.
Female unknown.
