Digonocryptus arcaeus Aguiar et Ramos, 2011

Morphological variation. In one female ( French Guiana, 05.XI.2010) the dorso basal yellow spot on the hind coxa is entirely lacking, so the coxa is fully reddish. Fore and mid tibiae vary from fully yellowish brown to almost entirely dark brown, sometimes even for specimens from close locations. For example, of 11 female specimens examined from the Nouragues Reservation, one shows fore and mid tibia fully yellowish brown, while for all other they are 50–90% dark brown. The T2 of a female from Cochabamba ( Bolivia) shows a faint, thin yellow stripe apically, contrasting with T2 entirely orange on all other observed specimens.

Comments. The absence of a yellow area or spot on the hind coxa was unknown for this species, and will conflict with couplet 34 in the key by Aguiar and Ramos (2011), but it does seem, however, to be an unusual record for the species. See also comments for D. diversicolor .
