Male genitalia
: Cephalic region of pygophore with prominent tergal apodemes, tergum with dorsal marginal thickening which is broken at point of articulation with segment X, beyond this with a mesal inflexion which holds the body of aedeagus in place. Segment X stout, dorsal half sclerotized, with a caudoventral bifid process. Subgenital plate and valve as in generic diagnosis. Aedeagus placed more dorsally, most of shaft placed beyond dorsal margin of pygophore. Aedeagus broadest in middle, with anteriorly directed welldeveloped dorsal apodeme, shaft abruptly turned dorsally almost at right angles, narrowed distally with a pair of lateral toothlike processes at mid length and another pair adjacent to gonopore, anterodorsally compressed, spatulate near apex, gonopore subapical with a narrow laminar ridgelike extension on either side; preatrium of aedeagus produced into ventrocaudally directed paraphyses.
