Diagnosis

Females of this species are very similar to those of A. inornatus , with T1 punctate but punctures not strongly impressed. It differs from A. inornatus by the mesoscutum disc sparsely punctate, interspaces more than puncture diameters, surface mostly polished. Males are easily recognized by the submarginal rows of long (= 2od) recurved setae on S4–5 ( Fig. 8G ).

Etymology

A god of the underworld, punisher of broken oaths in Italic and Roman mythology. Orcus was portrayed in paintings in Etruscan tombs as a hairy, bearded giant. The name is used as a proper noun in apposition.
