BRIEF DESCRIPTIVE NOTES (after Chamberlin [1955] and Kraus [1956]). Length 45 mm, width 5.0– 5.3 mm (♂, ♀). Coloration dull red-brown to chocolate brown with contrasting yellow paraterga and a moderately wide, light, axial stripe; legs light brown. Paraterga well-developed and strongly rimmed, anterior corners stronglY rounded, calluses clearlY set off from a smooth lateral rim; caudal corners mostly rounded and only slightly drawn past straight rear tergal margins ( Fig. 11A ). Epiproct short, cylindrical, slightly curved ventrad. Hypoproct roundly triangular with two thick setigerous knobs at caudal margin. ♂ legs ventrallY with prefemora carrYing apical swellings, and tibiae with apical chelae.

Gonopods ( Fig. 11B–F ) with prefemoral process (PfP) considerably longer than acropodite (A), both highly complex and strongly armed; PfP subrectangular in shape, with an elongated projection in its middle portion, ending in a bifid projection; apical portion of PfP slightly bipartite, with two acute branches directed laterally; A broad, with an irregularly shaped apex featuring several indentations; internal margin near apex with a small invagination subsequently forming a small subacute process; solenomere (sl) simple, subflagelliform and only slightly curved.
