Description.

Eyes prominent; antennae and legs longer than in the others species of the complex. Length of first antennal segment equal or slightly shorter than the distance between the eyes.

Paramere distally shorter and more thickened than in Nabis faminei and Nabis punctipennis . Paramere with a thickening on the inner margin of the blade and a protuberance on the outer margin of the blade. Female genitalia with the styloid constricted basally and sharp distally.
