Other material examined.
1♂ 1♀ (NHMSU-HA123) China: Yunnan Province, Lushui County, Pianma Township, Changyanhe River , 9.3 km of ESE Pianma , mixed broadleaf deciduous and evergreen forest, in leaf litter (25.99363°N, 98.66651°E; 2470 m alt.), 10.VIII.2018, Y.

Lin et al. leg GoogleMaps .
Diagnosis.
The male of P. xiaoxiao can be distinguished from other congeners, with the exception of P. woodwardi , by the stout bulb lacking a conductor or median apophysis and having a finger-like tegular process (Fig. 14A View Figure 14 and B View Figure 14 ). It differs from P. woodwardi by having the entire embolus completely embedded in the bulb (cf. Fig. 14A View Figure 14 and B View Figure 14 and fig. 120 in Forster 1959). Females of P. xiaoxiao differs from those of other congeners by having a wide, triangular parmula, dumb-bell-shaped spermathecae separated by ~ 1.5 × their width and arranged longitudinally in parallel, the copulatory ducts coiling into a loop and connecting to the postero-lateral corner of the spermathecae, the fertilisation ducts begin latero-medially on the spermathecae (Fig. 14C-E View Figure 14 ).
New morphological data.
Male (NHMSU-HA123). Total length 0.56. Carapace 0.28 long, 0.28 wide, 0.28 high. Clypeus 0.12 high. Sternum 0.20 long, 0.20 wide. Abdomen 0.36 long, 0.36 wide, 0.44 high. Length of legs: I 0.80 (0.20, 0.10, 0.20, 0.12, 0.18); II 0.72 (0.20, 0.10, 0.14, 0.12, 0.16); III 0.58 (0.14, 0.08, 0.14, 0.10, 0.12); IV 0.66 (0.18, 0.10, 0.14, 0.12, 0.12).
Somatic characters (Fig. 13A-C View Figure 13 ). Colouration: carapace light brown, thoracic centre and margin with darker patches. Mouthparts nut brown, endites and labium black. Sternum black, with a few light, small dots. Leg colour light yellow gradually grading to very dark brown, tibia darkest brown. Abdomen dorsally light grey, laterally dark greyish, ventrally and posteriorly charcoal black. Prosoma: carapace as long as wide, nearly round. Cephalic part vertical anteriorly and sloped posteriorly. Eyes, subequal in size. PER slightly recurved, ALE protruded. Chelicerae anterior surface flat. Labium semi-circular, wider than long. Sternum smooth, slightly plump. Legs: each patella with 1 disto-dorsal seta, 1 proximal and 1 disto-dorsal seta on each tibia. Tibia II with 2 ventral clasping spines. Opisthosoma: dorsally globose, laterally ovoid, clothed with black, long setae, cuticle rough with dots of varying shades and sizes. Spinnerets dark brown.
Palp (Fig. 14A View Figure 14 and B View Figure 14 ): size ~ ¼ of carapace. Femur swollen, wider than patella, patella as long as ~ ½ length of tibia. Tibia flat and lamellar. Tegulum smooth, with finger-like apical process. Embolus long, starting at retrolatero-medial part of tegulum, coiled into 2 loops inside bulb. Tip of embolus hidden within tegulum, not extended from top of bulb.
Female. Total length 0.56. Carapace 0.28 long, 0.28 wide, 0.24 high. Clypeus 0.08 high. Sternum 0.20 long, 0.20 wide. Abdomen 0.36 long, 0.32 wide, 0.40 high. Length of legs: I 0.70 (0.20, 0.06, 0.16, 0.14, 0.14); II 0.62 (0.14, 0.08, 0.14, 0.12, 0.14); III 0.52 (0.12, 0.06, 0.12, 0.08, 0.14); IV 0.60 (0.12, 0.08, 0.16, 0.10, 0.14).
Somatic characters (Fig. 13D-F View Figure 13 ). Colouration: as in male, except lighter mouthparts and sternum. Prosoma: carapace longer than wide, pear-shaped. Eye arrangement as in male. PER straight. Cephalic part lower than in male. Legs: spination as in male, except for lack of clasping spines on tibia II. Opisthosoma: subovoid in dorsal view, cuticle. Spinnerets dark grey.
Epigyne (Fig. 14C-E View Figure 14 ): faintly sclerotised, internal structures nearly invisible via the cuticle. Parmula triangular, length equal to ca. ½ width, slightly protruded. Spermathecae nearly dumb-bell-shaped, longitudinally parallel, separated by ~ 1.5 × their width. Copulatory openings large. Copulatory ducts translucent, their width equal to ca. 2.5 × width of fertilisation ducts and folded at middle, distal part connected with postero-lateral part of spermathecae. Fertilisation duct shorter than a spermatheca length, narrow, originates from the lateral central position of spermathecae.
Distribution.
China (Yunnan) (Fig. 23 View Figure 23 ).
Remarks.
Patu xiaoxiao was described, based on three females. Based on supplementary materials from the type locality collected in 2018, the male is described for the first time here.
