Types.
Holotype: ♂ (IZCAS), Indonesia, East Kalimantan, Penajam, Camp of International Timber Corporation of Indonesia, 1°5.2915'S, 116°41.0938'E, 64 m, 16.VIII.2014, H. Zhao & Z. Yao.
Etymology.
The species name is an adjective referring to the type locality.
Diagnosis.
The male of P. penajamensis sp. nov. can be recognized by the structure of laminar apophysis of the bulb that arises distally, bearing the embolus and bulge (Fig. 17B View Figure 17 ) (vs. absence of laminar apophysis in congeners), a relatively short clypeal protrusion in which the length does not exceed the anterior tip of the carapace (vs. a clypeal projection that exceeds the anterior tip of carapace).
Description.
Male (Holotype). Total length 1.20; carapace 0.50 long, 0.60 wide; abdomen 0.70 long, 0.50 wide. Carapace round and brown, with 3 longitudinal dark brown bands, median band and lateral bands nearly the same width (Fig. 16B View Figure 16 ). Chelicerae brown (Fig. 29A View Figure 29 ). Clypeus dark brown, bearing few setae, with short medial projection, length does not exceed the anterior edge of carapace, (Fig. 16A, B View Figure 16 ). Endites brown. Labium dark brown. Sternum dark brown. Abdomen elongated, dorsum with dark brown patches concentrated posteriorly (Fig. 16B View Figure 16 ), antero-ventrally dark brown with complex patterns (Fig. 16C View Figure 16 ). Legs uniformly brown; measurements: I-III missing, IV 6.30 (1.56, 0.16, 1.90, 1.80, 0.88). Palp (Fig. 17A-D View Figure 17 ): femur slender, 3 times longer than patella; patella not swollen; tibia 1.5 times shorter than femur; cymbium almost as long and wide as tibia, protrusion darkens distally; bulb pale yellow, pyriform with bulge, laminar apophysis and embolus arise distally; laminar apophysis sheet-like, almost as long as width of tegulum; laminar apophysis adjacent to embolus, embolus dark short, and pointed; blunt bulge adjacent to embolus (Fig. 17B View Figure 17 ).
Female. Unknown.
