lacking a white blotch in the upper hind corner of the mesopleuron. 
The sparse 2nd gastric punctures (separated mostly by 1-3X their 
diameters) also separate C. teres from other members of its species 
group (2nd gastric punctures subadjacent to adjacent). 
Field Notes. The unique holotype was swept from semishaded 
undergrowth along a dry river bed at Simbal near Trujillo, Peru. 
This locality, at the lower extreme of a fertile valley in the north 
Peruvian Coastal Desert, has a natural vegetation dominated by 
Prosopis, Acacia, Opuntia, Cereus, and much other Thorn Scrub 
(Sonoran-Chaquenan) vegetation. 
Specific Name. From the Latin adjective teres, “polished, 
rounded, elegant.”
