Type material.
Holotype ♂ (IZCAS-Ar 41036) Vietnam: Cat Ba National Park, Hai Phong Province, in leaf litter of natural forest (20.80133°N, 107.00353°E; 116 m alt.), 23.IX.2007, D. Pham leg.
Etymology.
The specific epithet derives from the type locality; noun in apposition.
Diagnosis.
This new species differs from other Patu species with the exception of P. damtao sp. nov. by having a long, sclerotised conductor dorsally on the bulb (Figs 1D View Figure 1 and 4D View Figure 4 ). It can be distinguished from P. damtao sp. nov. by the blunt conductor swollen basally, the shorter embolus forming no more than one loop and the presence of a median apophysis (Fig. 1D View Figure 1 and E View Figure 1 ) vs. a sharp conductor constricted basally, a longer embolus forming more than one loop and the absence of a median apophysis (Fig. 4D View Figure 4 and E View Figure 4 ).
Description.
Male (IZCAS-Ar 41036). Total length 0.56. Carapace 0.24 long, 0.28 wide, 0.32 high. Clypeus 0.14 high. Sternum 0.16 long, 0.16 wide. Abdomen 0.40 long, 0.36 wide, 0.40 high. Length of legs: I 0.74 (0.20, 0.10, 0.16, 0.12, 0.16); II 0.66 (0.20, 0.10, 0.12, 0.10, 0.14); III 0.50 (0.12, 0.08, 0.08, 0.08, 0.14); IV 0.56 (0.12, 0.10, 0.12, 0.10, 0.12).
Somatic characters (Fig. 1A-C View Figure 1 ). Colouration: carapace brown, nut brown at margins, ocular base black, thoracic region reticulated medially. Chelicerae, endites and labium dark brownish. Sternum nut brown. Legs brownish to dark yellow, except femur I yellow. Abdomen brown and grey, with dense, light dots. Prosoma: carapace wider than long, nearly pyriform. Eyes with ocular tubercles, PME> ALE> PLE, ALE protruded, PER recurved. Sternum slightly swollen, smooth and glossy, sparsely punctate. Legs: with 1 dorso-distal seta on each patella and 1 seta on each tibia sub-proximally. Tibia II with 2 subdisto-ventral clasping spines. Opisthosoma: dorsally rounded, laterally nearly ovoid. Spinnerets brown, darker at edges.
Palp (Fig. 1D View Figure 1 and E View Figure 1 ): large, ~ ⅓ size of carapace. Femur slightly swollen, patella ~ ½ length of tibia, tibia flat. Cymbium translucent, membranous, surrounds bulb prolaterally, with a finger-like extension, with 2 distal, long setae. Bulb subovate. Tegulum smooth. Median apophysis short, not extending beyond apex of bulb. Conductor long, finger-like, sclerotised, basally swollen, distally blunt. Embolus ca. 2 × length of conductor, ribbon-like, middle portion embedded in tegulum, distal portion looped at the apex of bulb.
Female. Unknown.
