Short general description of the species PROSOMA. With few dispersed long and short setae; lateral prosoma borders provided with very short setae, anterior clypeal border with long setae; clypeus with a proximal central long seta; ocular area with a long seta just above AE; chelicerae with one proximal median long seta; coxae with dorsal setae. OPISTHOSOMA. Few dispersed long and short setae (only short setae in female). LEGS. Pa III & IV without dorsal spines. PALP. Tibia of male palp with 1 dorsal and 3 prolateral spines; RTA with hooked tip; VTA inconspicuous. Embolus with retrolateral origin, slowly curled at tip. Cymbium without tutaculum or tutacular groove. EPIGYNE. Atrium with sclerified anterior and lateral borders and raised hood, small spermathecal organs conspicuous, close to epigynal fold ( Fig. 2C); vulva with irregularly shaped spermathecae with mesal spermathecal organs, thick curled copulatory tubes ( Fig. 3A). This species shows variation in colour among males and between males and females. There is, however, no specific distribution pattern of the three kinds of colour patterns.
