Chelicerae: mastidia absent; stridulatory striae rows compressed and evenly spaced ( Fig. 39A ). Legs: dorsal proximal macroseta on tibia IV 3.1 times diameter of tibia; Tm I: 0.34. Pedipalp: patella prolateral proximal vertical macrosetae absent; tibia with one prolateral, two retrolateral trichobothria; TPS slightly scaly, distalretrolaterally pointed; TPA absent; TRA apically oriented ( Fig. 52B ); PC median-sized, base not visible from dorsal view, distal setae close to distal clasp, distal clasp without striae, clasp directed slightly apically; T without papillae, PT with small papillae, TS as long as PT, without papillae; MSA present ( Fig. 52A ); DSA tip anteriorly oriented; EM flat, anterior margin without papillae, exceeds ARP ( Fig. 52B ); ARP pointed, angled ventrally; LER without striae, extended dorsal to E; VRP absent; TP tip narrow; E retrolaterally spiral, anterior margin at base slightly wavy ( Fig. 52B, C ).
