Colocistis castanea (Cresson)Wikispecies linkPensoft Profile


The simple second metasomal sternum distinguishes Colocistis castanea, Colocistis oaxacana and Colocistis thermarum from other species of Colocistis. Colocistis castanea and Colocistis oaxacana share a flattened clypeus in profile (elevated and tuberculate in Colocistis thermarum). The concolorous body color and unmodified vertex will distinguish Colocistis castanea from Colocistis oaxacana. No structural features, only color could be found to distinguish Colocistis stygia from Colocistis castanea.


Body length. 10–15 mm.
Head (Fig. 2). Head: compound eyes enlarged, extending laterally far beyond temples, inner margins somewhat emarginated; ocelli enlarged, diameter of lateral ocellus at least 0.7× OOL, removed from vertex by 0.5 or less one ocellar diameter in frontal view; impressed line present between lateral ocelli posteriorly; clypeus nearly flat, not visible above mandibles in lateral view, without projecting tubercle, apex not margined by strong teeth; antennal socket rim only slightly thickened ventrolaterally; LID 0.7× UID; flagellomere I length 2.3–2.5× breadth; flagellomere II length 2.5–2.6× breadth; flagellomere IX length 4.5–5.0× breadth; occipital carina strong but incomplete ventrally; mandible narrowest submedially, tapering apically toward ventroapical tooth (Fig. 17).
Mesosoma. Pronotal punctures deep, contiguous, shoulders well developed, not produced laterally; forefemur without stout spines; foretibia without spines except apically; basitarsus with row of three spines on outer surface; tibial spur 0.9× length of basitarsus; hindcoxa with longitudinal carina on ventral surface (Fig. 15), longitudinal dorsal carina not tooth-like; scutal, scutellar and mesopleural punctures large, separated by 1–3 puncture diameters; scutellum elevated above level of propodeum, with polished impunctate area medially; postscutellum densely punctate; propodeum dorsal surface coarsely rugose, with irregular, shallow, longitudinal medial groove, posterior surface separated from dorsal by transverse ridge, posterior surface polished, nearly impunctate, lateral surface dorsally with contiguous punctures becoming sparsely punctate to impunctate ventrally; forewing with 3 submarginal cells; costa continuing along wing margin beyond stigma.
Metasoma. Tergum I without transverse carina (Fig. 20); sternum II without raised area basally.
Genitalia (Figs 42, 49). Gonostylar apex arcuately excavate in lateral view; aedeagus not decurved before apex.
Color. Head and body concolorous castaneous to black; vestiture light brown.
Female unknown.
