Diagnosis

Scutum outline alpha-type, scutum flattened in lateral view, lateral border in posterior view following the general body curvature. Protoglyph guards are triangular. Mesotergal grooves are shallow, straight. Scutal areas I–IV are each armed with a pair of small flat tubercles which are white, sharply contrasting with the brown background, area V with a transverse row of a few such tubercles. Cheliceral hand is somewhat swollen in male, and the basichelicerite of male is clearly stouter, with a coarsely tuberculate posterior rim. Coxa IV with oblique orientation. Femur IV sexually dimorphic, clavate in males, in female thinner and curved proximally. Basitarsus I thickened in male. Tarsal counts: 5(3)/8–9(3)/6–7/7. Male genitalia: VP subrectangular. Wattle is complete. MS D1 is clearly smaller than C. Two long lateral patches of microsetae T4 without midfield.
