Type material.

Holotype ♂: Thailand, Tak Province, Umphang District, Mae Klong Subdistrict, field, 16°14.642'N, 98°59.914'E, 1228 m, 17 XI 2016, H. Zhao, Y. Li & Z. Chen.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

Small-sized Pseudopoda species. Male has long spiral embolus that resembles P. parvipunctata Jäger, 2001 (see Jäger 2001: 94, figure 49 e–l) and P. spirembolus Jäger & Ono, 2002 (see Jäger and Ono 2002: 112, figs 11-14). It can be distinguished from the two congeners by the following combination of characters: 1. tegulum small, leaning towards the retrolateral margin of cymbium (Figure 12B); 2. embolic projection long, arising from the basal part of embolus at 9 o’clock position, forming a semicircle with its basal part running along with embolus and covering a part of it like a sheath (Figure 13A, B; absent in P. spirembolus and P. parvipunctata ); 3. embolus extremely long, forming five loops (Figure 13A, B; forming three loops in P. spirembolus ; two in P. parvipunctata ); 4. cymbium flattened and broadened without any bulges (Figure 12 A–C; elongated and with one bulge on the retrolateral margin in P. parvipunctata ; broadened and with one bulge on the retrolateral margin in P. spirembolus ).

Spination: palp 131, 101, 2101; legs: femur I-II 323, III 333, IV 331; patella I-IV 101; tibia I-IV 2026; metatarsus I-II 1014, III 2024, IV 3037. Measurements of palp and legs: palp 8.4 (3.0, 0.8, 1.2, -, 3.4), leg I 21.9 (5.9, 2.4, 6.4, 5.4, 1.8), leg II 23.4 (6.4, 2.5, 6.7, 5.8, 2), leg III 17.2 (5.1, 1.8, 4.8, 4.1, 1.4) leg IV 21.5 (6.2, 1.8, 5.5, 6.2, 1.8). Promargin of chelicerae with three teeth, retromargin with four teeth. Cheliceral furrow with ca. 38 denticles.

Palp as in diagnosis. Cymbium large. RTA arising basally from tibia. Both vRTA and dRTA flattened and blunt in ventral view (Figure 12 A–C). Sperm duct S-shaped, running retrolaterally in tegulum. Embolus arising from tegulum at 9 o’clock position, extremely elongated. Conductor large and elongated, arising from the tegulum at 10 to 12 o’clock position (Figure 13A, B).

Coloration in ethanol: carapace yellow. Radial furrows and fovea brown. Dorsal opisthosoma yellowish to reddish brown. Legs yellow, with randomly distributed brown dots (Figure 13C, D).

Female. Unknown.
