Hypandrium long, narrow, with a wide based, elongate, stout, curved acuminate posterior projection in the middle ( Fig. 34 ).

Paraprocts broad, setose, with a long, stout, acuminate mesal prong, bearing a small denticle in the middle of the inner edge. Sensory fields with 18–20 trichobothria in basal rosettes ( Fig. 32 and 33 ).
