Glyptometopa eureka Banks, 1912:202. Holotype female; USA: Arizona, Palmerlee (MCZ).

Diagnosis.

Colocistis eureka shares the strongly elevated gular carina with Colocistis segredentata . However, in Colocistis eureka the carina is strongly biangular or bidentate versus medially uninterrupted and the meso- metapleural sulcus is faint but distinct, versus absent or incomplete in Colocistis segredentata .

Maleunknown.

Description.

Female.

Body length. 9.5-10.0 mm.

Head. Wider than long in anterior view; vertex with lateral foveae consisting of row of large, shallow punctures; occipital carina ( Fig. 10 ) meeting transverse carina at obtuse angle, transverse carina irregular, notched medially between submedial teeth, subtended by irregular rugae toward occiput.

Mesosoma. Pronotal disk 0.4 × as long as broad in dorsal view, nearly impunctate, with several scattered punctures; propleura densely punctured; foretibia with two spines laterally; basitarsus with two spines on outer surface; tibial spur 0.9 × length of basitarsus; hindcoxa ventral carina extending 0.5 length of coxa, dorsal longitudinal carina broadly elevated basally.

Metasoma. Sternum I without medial groove ( Fig. 21 ).

Color. Reddish brown; vestiture whitish to pale yellow.

Distribution
