Valve triangular; wider than 2x median length. Subgenital plate triangular; with single row of 11–12 macrosetae laterally; with several long fine setae laterally. Style lateral arm produced anteriorly; preapical lobe very slight; apophysis thick; apex blunt slightly pointed laterad. Connective-aedeagus without any processes. Aedeagus robust, U-shaped; without processes. Phragma not forming distinct bulbous lobes; membranous, with short setae throughout. Segment X membranous.
