Circocerus perplexus Motschulsky, 1855 View in CoL

Circocerus perplexus Motschulsky 1855 View in CoL . Type locality: Obispo, Panama. Specimens examined: 2 females: // Circocerus perplexus View in CoL m Obispo/ [gold circle]/ C. Motschulsky/ SYNTYPES Circocerus perplexus Motschulsky View in CoL // [ZIN]. Two males: //[green label] Obispo/ [green label] ♂ / Circocerus perplexus Motsh. View in CoL Panama / SYNTYPES Circocerus perplexus Motschulsky View in CoL // [ZMUM]. Newton and Chandler 1989: 58 (as type species of genus). Chandler 1992: 353.

Length 1.50–1.76 mm. This species is among the smallest of Circocerus View in CoL seen from Panama and Costa Rica. My notes on the male types of C. perplexus View in CoL record a moderately developed, oblique apical spine on the protrochanters and no additional spines on the forelegs. However, there are two apparent species from Panama and Costa Rica that fit this description, that differ slightly in the form and angle of the protrochanteral spine. At this time, the exact identity of C. perplexus View in CoL is uncertain.
