General appearance as in Fig. 14A . Carapace oval, very high. Coloration of carapace dark brown to blackish, in some specimens traces of light line along its middle, vicinity of eyes black. Very short prostrate hairs on carapace, their coloration brownish and grey, only near eyes long brown bristles. Clypeus clothed in white hairs.

Abdomen oval, dark brown, venter dark too. Some long brown hairs at anterior abdominal margins. Spinnerets brown. Legs dark brown, their hairs delicate, brown and greyish. Spines long. Pedipalps small, brown, with long hairs. Cymbium narrow, its retrolateral edge rolled up ( Fig. 14C, D ). Bulbus irregularly shaped, with long apical lobe and very thin horizontal process at embolus base ( Fig. 14C, E ). Embolus at tip of bulbus, long and thin, forming large loop. Embolus base wide, membranous ( Fig. 14D ). Palpal tibia short, with two apophyses; retrolateral of them rather small, almost horizontal; dorsal one thin, quite flat and very long ( Fig. 14C, D ).
