Name
Colocistis brevis (Cresson) – Wikispecies link – Pensoft Profile
- Brachycistis brevis Fox, 1899:285. Holotype male; USA: California (ANSP).
Diagnosis
This is one of three species in Colocistis, with two submarginal cells, including Colocistis eremi and Colocistis chemsaki, and one of two (Colocistis eremi) with the costal vein not extending beyond the stigma. It can be distinguished from Colocistis eremi by the hypostomal carina not elevated anteriorly (strongly elevated in Colocistis eremi) and the aedeagus in lateral view slightly decurved (not decurved in Colocistis eremi).
Description
Male.
Body length. 5–11 mm.
Head (Fig. 1). Compound eyes enlarged, extending laterally far beyond temples, inner margins somewhat emarginate; ocelli enlarged, diameter of lateral ocellus at least 0.7× OOL; vertex with impressed line between lateral ocelli absent or reduced to a row of punctures; postvertex not visible behind ocelli in frontal view; lateral ocelli separated from vertex by 0.5 or less one ocellar diameter in frontal view; clypeus raised medially and visible above mandibles in lateral view, apex not bounded laterally by strong teeth; gular carina gradually elevated anteriorly.; LID 0.8× UID; flagellomere I length 2.3–2.5× breadth; flagellomere II length 2.5× breadth; flagellomere IX length 5.5–6.0× breadth; occipital carina strong, complete ventrally, with strong carina extending from foramen magnum to hypostomal carina medially; mandible narrowest submedially.
Mesosoma. Pronotal punctures deep, contiguous; forefemur without stout spines; foretibia without spines except apically; basitarsus with three spines on outer surface; tibial spur as long as basitarsus; hindcoxal longitudinal dorsal carina basally angulate; mesopleural punctures contiguous; scutellum not strongly elevated above level of propodeum; scutal and scutellar punctures 1–4 puncture diameters apart; postscutellum densely punctate; propodeum dorsal surface densely irregularly rugose, with irregular longitudinal submedial and sublateral carinae, posterior surface transversely, densely ridged, with large, dense punctures laterally; lateral surface impunctate ventrally becoming densely punctate dorsally; forewing with two submarginal cells, costa not extending along wing margin beyond stigma.
Metasoma. Tergum I without transverse carina; sternum II without raised area anteriorly.
Genitalia (Figs 42, 50). Gonostylus evenly curved to tip, aedeagus slightly decurved in lateral view.
Color. Head and body concolorous castaneous; vestiture brown.
Female unknown.
Distribution

USA: Arizona: Maricopa, Pima, Yuma counties; California: Imperial, Inyo, Riverside, San Bernardino, San Diego counties; Nevada: Lincoln, Nye counties; Texas: El Paso County; Mexico: Baja California, Baja California Sur, Sonora; 990 males were examined including the type (BME, EMEC, KSBS, LACM).
