Endites with thickened tip bearing rounded protrusion. Abdomen without pigment patches. Embolus long, sinuous, with recurved tip.

FEMALE (PBI_OON 382, figs. 354–383, 391–400): Total length 1.51. Dorsum of abdomen with traces of dark pigment patches visible through cuticle. Anterior genitalic process very wide, situated on oval base followed posterior by strongly sclerotized, procurved ridge.
