Type material.

Holotype ♂: Myanmar, Kachin State, Putao, road to Ziradum Village, 27°33.617'N, 97°06.567'E, 1003 m, 13 XII 2016, J. Wu.

Etymology.

The specific name is derived from the Chinese Pinyin word for 'large size' ( dà xíng), referring to the relatively large body size of the species; noun in apposition.

Diagnosis.

Median-sized Pseudopoda species. Male resembles those of P. contraria Jäger & Vedel, 2007 ( Jäger and Vedel 2007: 31, figs 114-119) and P. semiannulata Zhang, Zhang & Zhang, 2013 (see Zhang et al. 2013a: 279, figs 13-24) by: 1. embolus extremely expanded, covering nearly half of tegulum; 2. embolus plate-like, with embolic projection on its prolateral margin (Figure 9A, B). It can be distinguished from the two congeners by the following combination of characters: 1. sperm duct running near the prolateral margin of embolus (Figure 9A, B; running near the retrolateral margin in P. contraria ); 2. tip of embolus and embolic projection slightly bent, pointing distally (Figure 9A; both much more strongly bent in P. semiannulata , tip of embolus pointing prolaterally, embolic projection pointing basally).

Description.

Male (holotype). Body length 12.4, DS length 6.0, DS width 5.4, OS length 6.4, OS width 3.2. Eyes: AME 0.30, ALE 0.41, PME 0.36, PLE 0.37, AME-AME 0.22, AME-ALE 0.08, PME-PME, 0.26, PME-PLE 0.46, AME-PME 0.44, ALE-PLE 0.43, CH AME 0.57, CH ALE 0.41. Leg formula: II-IV-I-III. Spination: palp 131, 101, 2111; legs: femur I-III 323, IV 321; patella I-IV 001; tibia I-IV 2026; metatarsus I-II 1014, III 2024, IV 3036. Measurements of palp and legs: palp 9.4 (3.1, 1.4, 1.8, -, 3.1), leg I 29.3 (8.3, 3.0, 7.8, 7.8, 2.4), leg II 32.1 (8.7, 3.2, 9.0, 8.5, 2.7), leg III 25.1 (8.0, 2.6, 6.5, 6.0, 2.0), leg IV 29.4 (8.5, 2.5, 7.3, 8.5, 2.6). Pro margin of chelicerae with three teeth, retromargin with four teeth. Cheliceral furrow with ca. 25 denticles.

Palp as in diagnosis. Cymbium slender, with retrolateral bulge. RTA arising basally to mesially from tibia, dRTA hook-like, vRTA broad (Figure 8 A–C). Sperm duct running submarginally retrolaterally in tegulum, then near the prolateral margin of embolus, meandering like a river flowing around mountains. Embolus arising from tegulum at 9 o’clock position. Conductor arising from tegulum at 12 o’clock position, leaning prolaterally (Figure 9A, B).

Coloration in ethanol: carapace yellowish brown. Radial furrows and fovea dark brown. Dorsal opisthosoma reddish brown. Ventral opisthosoma with a pair of longitudinal bright lines. Legs yellowish brown, with randomly distributed brown dots (Figure 9C, D).

Female. Unknown.
