Type material.

Holotype: ♂, near the entrance of Phra Kha Yang Cave (10°19.568'N, 98°45.908'E, elevation 6 m), Kraburi District, Ranong, Thailand, 28 October 2014, P. Wongprom leg. Paratypes: 1♂, 2♀♀, same data as holotype.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

The species resembles Savarna tesselata (Simon, 1901) (see Huber 2005: 78, figs 129-130, 138-140), but can be distinguished by absence of median apophyses on male clypeus (Fig. 2E), by relatively wide pedipalpal tibia subproximally (Figs 1 A–B), and by shape of bifurcated distal apophysis on bulb (Fig. 1A).

Description.

Male (holotype). Total length 2.97 (3.13 with clypeus), prosoma 1.04 long, 1.34 wide, opisthosoma 1.93 long, 1.44 wide. Leg I: 27.73 (7.63 + 0.55 + 7.05 + 9.94 + 2.56), leg II: 18.52 (5.45 + 0.48 + 4.62 + 6.50 + 1.47), leg III: 13.52 (4.04 + 0.47 + 3.27 + 4.77 + 0.97), leg IV: 18.36 (5.64 + 0.48 + 4.49 + 6.73 + 1.02). Habitus as in Fig. 2E. Dorsal shield of prosoma yellowish, with black margins and a narrow, dark median line behind ocular area; sternum black. Legs brownish, but slightly whitish on femora (distally) and tibiae (distally), with slightly darker rings on femora (subdistally). Opisthosoma yellowish, with black spots. Distance PME-PME 0.20, diameter PME 0.12, distance PME-ALE 0.04, AME absent. Ocular area slightly elevated and separated from rest of prosoma. Thoracic furrow distinct and deep. Sternum slightly wider than long (0.87/0.78). Chelicerae as in Fig. 2D, with a pair of proximo-lateral apophyses. Pedipalps as in Figs 1 A–B; trochanter with a curved ventral apophysis lying against femur; procursus simple proximally but complex distally; bulb with a proximal sclerite and a bifurcated distal apophysis. Retrolateral trichobothrium of tibia I at 9%; legs with short vertical hairs on tibiae, without spines and curved hairs; tarsus I with more than 30 distinct pseudosegments.

Variation. Tibia I in another male: 6.73.

Female. Similar to male, habitus as in Figs 2 F–G. Tibia I (n=2): 6.22, 6.35. One of the specimens measured: Total length 2.69 (2.81 with clypeus), prosoma 0.89 long, 1.13 wide, opisthosoma 1.80 long, 1.47 wide; tibia I: 6.22. Distance PME-PME 0.18, diameter PME 0.12, distance PME-ALE 0.03, AME absent. Epigyne (Figs 2 A–B) strongly protruding, without pockets. Vulva (Fig. 2C) with a pair of pore plates.
