) general characters: genitalia elongate, length ca. 5x greatest width, basal piece shorter than parameres (ratio ca. 11/14); paramere tips extending beyond aedeagus tip, medial margins beyond aedeagus tip parallel, plsa small, lateral margins between plsa and apex straight, length unusually long; in lateral view paramere tips slightly arcuate toward dorsad, very sharply pointed apically; aedeagus wide, agw at ca. midlength, where aedeagus ca. 4x as wide as paramere, alm slightly emarginate between agw and distal end; basal piece in dorsal/ventral views nearly parallel-sided, in lateral view very slightly arcuate, orifice almost symmetrical, margin sclerotized.
