Colocistis sulcata (Mickel & Krombein) – Wikispecies link – Pensoft Profile
- Aglyptacros sulcata Mickel & Krombein, 1942:674. Holotype female; USA: Texas, Valentine (KSBS).
Diagnosis
Colocistis sulcata most closely resembles Colocistis paxillata based on the incomplete occipital carina and simple gular carina. It can be distinguished from Colocistis paxillata by the gular carina extending laterally beyond where the occipital carina would join if extended and metasomal sternum I medial longitudinal trough narrow and deep anteriorly, becoming broad and shallow posteriorly; parallel-sided in Colocistis paxillata.
Male unknown.
Description
Female.
Body length. 7–12 mm.
Head. Twice as wide as long in anterior view; vertex with lateral fovea a row of circular punctures; occipital carina meeting transverse carina at nearly right angle, transverse carina extending laterally further than occipital carina (Fig. 12).
Mesosoma. Notal punctures deep, scattered, 1–5 puncture diameters apart; pronotal disk 0.5× as long as broad in dorsal view, punctures 3–5 puncture diameters apart; propleura coarsely rugosopunctate; forefemur without stout spines; foretibia without spines except apically; basitarsus with row of three spines on outer surface; tibial spur as long as basitarsus; hindcoxal ventral carina extending half length of coxa; dorsal longitudinal carina broadly elevated and lobe-like basally; meso-metapleural suture at most indicated by faint indentation.
Metasoma. Sternum I with medial groove narrowest anteriorly, broadened posteriorly, extending length of sternum.
