Gonostyli elongate, twice as long as broad, with apex broadly rounded and dorsal and ventral margins subparallel in lateral view (Fig. 15); strong hook-shaped tooth under dorsal margin close to pygofer, curved ventro-posteriorly and prolonged by a small rounded lobe on gonostylus wall dorsoposteriorly (Fig. 15).
