Male abdomen: Sternite 5 as long as sternite 4 medially, posteromedial area pale with a very pale central strip flanked by about 7 inclinate, short, stout bristles on each side; posteromedial margin with a straight comb of about 20 closely appressed flat bristles. Subanal plate complete, unusually high, fringed with short bristles on each side; ventral part of cercus projecting well below subanal plate, with one long and several shorter bristles. Surstylus broadly ovate, with a single long, narrow anteroventrally directed lobe bristle behind a posteriorly directed fingerlike lobe; fingerlike lobe with a smaller pale apical bristle. Distiphallus very narrow, tubular, tapered. Postgonite long and narrow, curved in apical third. Basiphallus frame-like, projecting posteriorly beyond distiphallus base for a distance almost equal to width of distiphallus base.
