Phoroncidia cibagou Gan, Mi & Wang sp. nov. Figs 5 C, D, 6, 7, 8 Type material. Holotype • ♂ (TRU -XZ-THR-0065), China: Xizang Autonomous Region, Linzhi City, Chayu County, Cibagou National Nature Reserve (28°36.03'N, 97°4.01'E, c. 2200 m), 22–27.VI.2023, C. Wang leg. Paratypes • 7 ♀ 3 ♂ (TRU -XZ-THR-0066 –0075), same data as for holotype. Etymology. The specific name is a noun in apposition and refers to the type of locality, Cibagou National Nature Reserve. Diagnosis. This species is similar to that of P. septemaculeata O. Pickard-Cambridge, 1873 in having similar copulatory organs, but it can be easily distinguished by the following: (1) origin of the embolus (E) after the embolic base is directed towards about 1 o’clock in retrolateral view (Fig. 6 C) vs towards the 4 o’clock (Nafin et al. 2019: fig. 3 A); (2) end of the prolateral tegular apophysis (PTA) is blunt and flat (Fig. 6 A) vs sharp and slender (Nafin et al. 2019: fig. 4 B); (3) copulatory ducts (CD) are forming a circle on proximal 1 / 3, and extending beyond the anterior-most level of the spermathecae (Figs 5 C, D, 7 B) vs not forming similar circle, and just extending to the median level of the spermathecae (Nafin et al. 2019: fig. 4 F); and (4) female abdomen is about trapeziform (Fig. 7 D) vs quadrate (Nafin et al. 2019: fig. 2 A). Description. Male (holotype; Figs 6, 7 C, E). Total length 2.75. Carapace 1.07 long, 1.03 wide. Abdomen 2.00 long, 1.95 wide. Carapace yellow brown except edge brown; ocular area protrudes more than female and extends forward to upper part of forehead. Chelicerae, endites and sternum yellowish-brown, labium brown, fused with sternum, endites, sternum and labium covered with brown setae. Legs overall yellow except femora, patellae, tibiae I and tibiae IV dark brown, and metatarsi I yellow brown, tibiae I with 5 short spines. Measurements of legs: I 4.37 (1.63, 1.18, 0.88, 0.68), II 2.86 (1.05, 0.88, 0.40, 0.53), III 2.32 (0.75, 0.73, 0.36, 0.48), IV 3.66 (1.40, 1.16, 0.49, 0.61). Abdomen sclerotized, dorsum yellow, covered with circular impressed dots, with eleven symmetrically arranged, circular orange-brown spots, four small and seven larger and edge with seven short and stout spines; later sub-triangular, with five circular orange-brown spots, and brown sclerotized ring encircled spinnarets; venter colored as dorsum. Palp (Fig. 6 A – C): femur yellow, c. 6 times longer than wide; patella and tibia almost equal in length; tibia gradually widened from base to distal end, with several dorso-distal setae; cymbium ~ 2 times longer than wide, with tapered antero-retrolateral hook with blunt tip; embolus (E) slender, originates from upper of retrolateral side of bulb, curved into C-shape at origin, and then extending along edge of bulb to top of conductor; embolic base (EB) sub-oval, with short, spiny, baso-prolateral apophysis; conductor (C) membranous and transparent; prolateral tegular apophysis (PTA) flat and elongated, about one-third cymbial length, end truncated. Female (TRU -XZ-THR-0066; Figs 5 C, D, 7 A, B, D, F). Total length 3.52. Carapace 1.41 long, 1.16 wide. Abdomen 3.03 long, 5.42 wide. Measurements of legs: I 5.10 (2.00, 1.45, 0.81, 0.84), II 3.24 (1.24, 1.00, 0.40, 0.60), III 3.03 (1.08, 1.00, 0.40, 0.55), IV 4.97 (1.86, 1.68, 0.65, 0.78). Habitus (Fig. 7 D, F) generally similar to that of male except bulge and protrusion of head region smaller, femora, patellae I dark brown, tibiae I without spines, abdomen sliver, and more swollen. Epigyne (Figs 5 C, D, 7 A, B): highly sclerotized, except part of anteromedian portion transparent, with sheet-shaped basal plate (BP) beyond epigastric groove; copulatory openings (CO) small, anterior to basal epigynal plate; copulatory ducts (CD) long, anteroprolaterally extending at origin until forming circle at proximal 1 / 3, then extending into invert U-shape, and distal end connected to bottom of spermathecae; spermathecae (S) pear-shaped, separated from each other ~ 1 / 4 their width; fertilization ducts (FD) tilted upwards. Distribution. Known only from the type locality in Xizang, China (Fig. 8).
