Palp (Figs 4 A – D View Figure 4 ). Patella as long as tibia, ventrally grooved, dorsally with long thick spine. Tibia cone-shaped, with two retrolateral and one dorsal trichobothria, retrolateral margin with nine thick spines. Cymbium with an ectal process wider than long, half the length of tibia, with bifurcated tip, both rami are almost equal in size and shape with blunt end; retrolateral margin of cymbium with thumb-shaped projection extending ventrally with blunt tip. Paracymbium bowl-shaped, apically hook-shaped, with median margin edge curved inward. Tegulum large, apically tapering. Conductor membranous, almost half the length of patella, present on apical end of tegulum. Embolus circular with fine tip, embolic flap horn-shaped, curved with pointed tip, embolic process sclerotized, apically with pointed tip, extending towards ventral side of tegulum.

Epigyne (Fig. 5 A – D View Figure 5 ). Epigynal plate wider than long. Most of the atrium divided by septum. Ventral plate oval, anteriorly grooved, posterior margin wavy. Copulatory openings present within atrium. Dorsal plate somewhat triangular, with broad tip posteriorly. Copulatory ducts sinuous, forming three curved loops before entering spermathecae. Spermathecae round, separated by distance equal to three times their diameter. Fertilization ducts present mesally.
