HABITAT AND LIFE HISTORY TRAITS. — We recorded this species in anthropized localities (pasturelands, villages, roadsides) near the shore. Willemse (1925) recorded it from Chuuri 300-600 m and Hog Harbour, open forest.

DESCRIPTION COMPLEMENT

Stridulatory file ( Fig. 11E View FIG ) with c. 57 lamellar teeth and numerous spinules on both sides of the file (already illustrated by Bailey [1979]).
