Colocistis segredentata (Mickel & Krombein) Figures 11 , 24 , 31, 32 , 38

Aglyptacros segredentata Mickel & Krombein, 1942:671. Holotype female; USA: Arizona, Benson (MCZ).

Diagnosis.

This might be the female of Colocistis castanea . It shares a number of characteristics with Colocistis eureka as discussed under that species. Colocistis castanea can be distinguished by the meso- metapleural suture absent or faint and incomplete and the medially interrupted transverse carina posterior to the gular carina.

Male unknown.

Description.

Female ( Figs 31, 32 ).

Body length 7.0-10.5 mm.

Head. Wider than long in anterior view; vertex with lateral foveae consisting of row of large, deep punctures; occipital carina meeting hypostomal carina at a right angle, hypostomal carina forming sharp angle on either side of midline; transverse carina short, irregular ( Fig. 11 ).

Mesosoma. Pronotal disk 0.4 × as long as broad in dorsal view; punctures widely separated, 2-10 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 0.9-1.0 × as long as basitarsus; hindcoxal ventral, longitudinal carina extending half length of coxa; dorsal longitudinal carina broadly elevated and lobe-like basally.

Metasoma. Sternum I with medial groove short, not extending much beyond base of sternum, or absent ( Fig. 24 ).

Color. Reddish brown; vestiture whitish to pale yellow.

Distribution
