Type specimens: Holotype : ♂ , China , Guizhou , Guiyang City , Wudang District , Guizhou Education University ( 26°38′53.138”N , 106°48′15.84”E , 755 m a.s.l. ), 16.VI–17.VII.2017 (leg. Z. X. Li and H. B. Wan ) ; Paratypes : 20 ♂♂ and 6 ♀♀ , same data as holotype ; 1 ♂ and 1 ♀ , same locality, 20.IV–3.V.2017 (leg. H. Yu and H. B. Wan ) ; 6 ♂ , same locality, 1–15. VIII.2017 (leg. Z. Q. Zeng and N. N. Lu ) . Diagnosis: Males easily distinguished from those of all other species of Mallinella , except M. kunmingensis ( WANG et al. 2009a : 51; Figs 13–21 ), by the digitiform retrolateral tibial apophysis, needle-shaped lateral ramus of embolus and by the general shape of median apophysis, but differ from the latter by: (1) median apophysis without tooth but with three denticles in M. kunmingensis (cf. Figs. 7, 16–18; WANG et al. 2009a : 52, fig. 20); (2) tip of the median apophysis not bifid and with folded apicoRprolateral process, vs. bifid and not folded in M. kunmingensis (cf. Figs. 16–18 ; WANG et al. 2009a : 52, fig. 20); (3) shape of the embolic tip (subterminal fold of mesal ramus point ventrally in M. pseudokunmingensis sp. n. , vs. point prolaterally and partly covered by embolic apex in M. kunmingensis ) (cf. Figs. 9 , 24; WANG et al. 2009a : 52, fig. 21); (4) abdominal pat- tern (1 st pair of spots fused to form trigonal patch in M. pseudokunmingensis sp. n. , vs. 1 st pair separated in M. kunmingensis ) (cf. Fig. 1 ; WANG et al. 2009a : 51, fig. 13). Female of M. pseudokunmingensis most similar to those of M. annulipes ( Thorell, 1892 ) by having V-shaped epigynal plate, swelling and reniform spermathecae but can be distinguished by: (1) wider lateral border (width-length ratio approximately 0.77 in M. pseudokunmingensis vs. 0.43 in M. annulipes ) (cf. Figs. 19–20 , 34–35 ; DANKITTIPAKUL et al. 2012 : figs. 733–734); (2) spermathecae with wrinkled and ribbed appearance in M. pseudokunmingensis , instead of smooth in M. annulipes (cf. Figs. 21–23 , 36–38 ; DANKITTIPAKUL et al. 2012 : figs. 737–738); (3) femora and tibiae without distal annulations (cf. Fig. 5; DANKITTIPAKUL et al. 2012 : Fig. 103); (4) dorsal pattern of abdomen (almost all pairs of spots fused together in M. pseudokunmingensis vs. all spots situated far apart in M. annulipes ) (cf. Fig 2 ; DANKITTIPAKUL et al. 2012 : fig. 713). Description : Male ( holotype ): Total length 7.86; carapace 3.46 long, 2.49 wide; abdomen 4.39 long, 2.76 wide.

Scale bars = 0.1 mm (24, 25–27, 28–30, 31–33). Epigyne as in Figs. 19, 21–23 , 34, 36–38 . Epigynal plate ( EP ) narrow and V-shaped, flanked with triangular lateral borders. Lateral border ( LB ) about 1.3 times longer than wide, terminally sharp about 30 degrees. Both lateral borders projecting inwards, separated by 1/2 length. Copulatory openings (CO) indistinct, located on anterolateral margin of epigynal furrow ( EF ) which situated on inner margin of lateral borders. Insemination ducts (ID) about as long as epigynal plate width, anteriorly thin, posteriorly thick, running transversely and then connecting with spermathecae. Spermathecae (S) reniform, about two times longer than wide, separated by two diameters, provided with subapical depression and posterolateral hump. Intraspecific variation: There were almost no differences between the paratype males from the holotype . Meanwhile, some intraspecific variations were found in females, most- ly related to different shape of epigynal plate and lateral borders. Epigynal plate typically V-shaped and lateral borders sharp, with acute angle (about 30 degrees) in some specimens ( Figs. 19 , 34 ), while epigynal plate more or less human lip-shaped and lateral borders blunt in other females ( Figs. 20 , 35 ). Distribution : Known only from the Guizhou Province of China ( Fig. 39 ).
