Sternum as long as wide, with oval field of clavate setae, covering about half of sternum width (fig. 25). Cheliceral fangs directed posteriorly forming a V shape, elongated, about O of paturon long, tips distally widened. Abdomen ovoid, epigastric scutum slightly protruding. Cymbium-bulb complex ovoid, bearing a long, medially bent embolus with a biarticulate basal apophysis (figs. 171–173).
