Prosoma longer than wide, covered with short and conical setae. Both anterior and posterior eyes disposed in two recurved rows; ALE almost two times larger than the other eyes; ocular macrosetae may be present only above the ALE or on the MOQ area; sternum heart-shaped with concave anterior border, and clypeus with a pair of macrosetae; labium trapezoidal and endites with rounded edges, longer than wide. Opisthosoma with two projections of different sizes, shapes and angles in relation to the opisthosomal axis, varying from rounded and short ones, disposed horizontally/posteriorly, or long, acute and vertically oriented (Figs 2
