Description.

Length of antennal segment II slightly longer than the width of the head across eyes. Hemelytra in macropterous form surpassing the apex of abdomen, in brachypterous form reaching eight segment. Paramere very similar to Nabis faminei , but with the blade slightly more widened and the base more constricted. Female genitalia with the styloid less thickened than in Nabis faminei .
