Segment IX rounded anteriorly in lateral view, deeply incised on posterodorsal margin; in dorsal and ventral view with deep lateral incisions posteriorly, deep mesal incision anteriorly. Segment X in lateral view rectangular, narrowing posteroventrally, thin median process from dorsum; dorsally trilobed, lateral lobes acute flaring outward to acute apices, mesal lobe short and tubular. Inferior appendages in lateral aspect widening distally from narrow base; in ventral view, narrow basally and widely separated, bearing elongate lateral seta, gradually widening posteriorly and turned outward at pointed apices. Subgenital plate in lateral view narrow and sinuate, sclerotized on dorsal margin; in ventral view triangular, narrow point mesally and bearing pair of stout setae. Phallus with basal section elongate, narrowing subapically, apical section elongate, wide basally narrowing distally and curving; ejaculatory duct thin, and slightly longer than phallic shaft; short paramere encircling shaft below juncture of apical and basal sections of phallus.
