Diagnosis

The male of Toxeus fodingensis sp. nov. closely resembles that of T. hainan Wang & Li, 2022 in the general shape of the habitus and palp, but it can be distinguished by the following: (1) the paturon having a small distal apophysis on the outside margin ( Fig. 53H ), whereas absent in T. hainan ( Wang & Li 2022b: fig. 18j); (2) the palpal tibia being about 1.5 times as long as wide in retrolateral view ( Fig. 52C ), whereas about 2.4 times as long as wide in T. hainan ( Wang & Li 2022b: fig. 17b). The female also resembles that of T. hainan in having very similar epigyne, but it can be easily distinguished by the epigynal hood, which is about three-fifths the spermathecal width ( Fig. 53A–B ), whereas about 1.3 times the spermathecal width in T. hainan ( Wang & Li 2022b: fig. 18b).

Etymology

The species name is derived from the name of the type locality, Foding Mountain National Nature Reserve; adjective.

Male (holotype)

MEASUREMENTS. Total length 6.51. Carapace 3.11 long, 1.67 wide. Abdomen 3.29 long, 1.27 wide. Eye sizes and inter-distances: AME 0.54, ALE 0.30, PLE 0.29, AERW 1.53, PERW 1.67, EFL 1.31. Legs: I 6.06 (1.95, 0.90, 1.78, 0.93, 0.50), II 5.06 (1.53, 0.75, 1.35, 0.93, 0.50), III 5.65 (1.65, 0.75, 1.30, 1.40, 0.55), IV 8.12 (2.28, 0.88, 2.13, 2.25, 0.58).

HABITUS. Carapace red-brown, with dark anterior and lateral margins, and sub-square cephalic region ( Fig. 53D–E ). Chelicerae with small distal apophyses on outside margins of paturon, and six teeth on both retromargin and promargin ( Fig. 53H ). Sternum about 2.6 times as long as wide ( Fig. 53F ). Legs yellow to red-brown except femora I dark brown, with one, five, and two pairs of ventral macrosetae on patellae, tibiae, and metatarsi I, respectively ( Fig. 53D ). Abdomen elongated, slightly constricted at anterior two-fifths, dorsum yellow-brown to dark brown, with pair of muscle depressions and several indistinct arc-shaped, transverse streaks, covered by big scutum posteromedially; venter with broad, longitudinal yellow-brown band medially ( Fig. 53D–F ).

PALP. Tibia about 1.5 times as long as wide in retrolateral view; RTA broadened at base, and continue bifurcated into reduced ventral ramus and sclerotized, tapered dorsal ramus twisted into an S-shape in ventral view, curved into pointed tip directed towards cymbium in retrolateral view; bulb flat, almost round; embolus flat, coiled with about two spirals, tapered to pointed tip at distal half ( Fig. 52 ).

Female (paratype, TRU-JS 0578)

MEASUREMENTS. Total length 6.45. Carapace 2.72 long, 1.36 wide. Abdomen 3.59 long, 1.60 wide. Eye sizes and inter-distances: AME 0.49, ALE 0.26, PLE 0.25, AERW 1.38, PERW 1.46, EFL 1.15. Legs: I 5.83 (1.78, 1.00, 1.70, 0.85, 0.50), II 4.86 (1.48, 0.75, 1.28, 0.85, 0.50), III 5.69 (1.63, 0.75, 1.38, 1.38, 0.55), IV 7.84 (2.20, 0.88, 2.05, 2.13, 0.58).

HABITUS. Similar to that of male except with dark thorax, and five cheliceral teeth on both retromargin and promargin ( Fig. 53G, I ).

EPIGYNE. With sub-square posterior hood; atria paired, round; sclerotized portions of copulatory ducts swollen into sub-cube at beginning, and then ascending as arc-shape to connect to posterior edges of sub-oval spermathecae; fertilization ducts originate from anterior edges of inner sides of spermathecae, slightly curved medially ( Fig. 53A–C ).

Distribution

China (Guizhou) ( Fig. 57 ).
