Endites with anteriorly narrowed, triangular anterior process. Leg spination: tibiae III, IV v0-0- 1p. Embolar region dorsoventrally elongated, embolus relatively short, small; retroventral projection of bulb with distally bent tip (figs. 198–202).

FEMALE (PBI_OON 31164, figs. 203– 212): Total length 1.77. Leg spination: tibiae: III v0-0-1p; IV v0-0-2; metatarsi IV v0-0-2. Anterior genitalic elements with short median and two longer paramedian anterior extensions, latter extension expanded anteriorly (figs. 211, 212).
