Type material.

Holotype ♂ ( TRU - JS 0732 ), China: • Xizang Autonomous Region, Medog County, Beibeng Township , Deergong Village , Yarlung Zangbo National Nature Reserve (29 ° 10.84 ' N, 95 ° 8.67 ' E, ca 1670 m), 25. V. 2024, X. Q. Mi et al. leg GoogleMaps . Paratypes • 1 ♂ 3 ♀ ( TRU - JS 0733–0736 ), same data as for holotype GoogleMaps .

Etymology.

The specific name refers to the type locality, Deergong Village; noun in apposition.

Diagnosis.

Icius deergong sp. nov. resembles I. yadongensis Hu, 2001 in general shape of copulatory organs, especially the invert infundibuliform base of copulatory duct, but can be easily distinguished by the bifurcated retrolateral tibial apophysis ( RTA), the presence of epigynal septum (Se) and proximally touching copulatory ducts ( CD) (Figs 5 B, C View Figure 5 , 6 A – D View Figure 6 ) vs non-bifurcated retrolateral tibial apophysis, lacking septum and copulatory ducts apart from each other proximally ( Hu 2001: fig. 8–247 - 2, 3, 5–7).

Description.

Male (Figs 5 View Figure 5 , 6 E, F, H, I View Figure 6 ). Total length 2.56. Carapace 1.16 long, 0.71 wide. Abdomen 1.43 long, 0.60 wide. Eye sizes and interdistances: AME 0.23, ALE 0.11, PLE 0.11, AERW 0.63, PERW 0.69, EFL 0.51. Legs: I 1.77 (0.53, 0.33, 0.40, 0.28, 0.23), II 1.42 (0.43, 0.25, 0.28, 0.23, 0.23), III 1.47 (0.43, 0.23, 0.30, 0.28, 0.23), IV 1.99 (0.60, 0.30, 0.48, 0.38, 0.23). Carapace elongated, grey-brown except eye field dark, with marginal white scale-like setal stripe; fovea indistinct. Chelicerae with two promarginal teeth and one retromarginal tooth. Legs pale with dark stripes except femora, patellae, and tibiae I dark brown; legs I with thickened femora, patellae, and tibiae, covered with cluster of dark ventral setae on patellae and tibiae. Dorsum of abdomen mainly dark brown, covered with dense dark setae, with several transverse, pale yellow lateral stripes; venter pale.

Palp (Fig. 5 A – C View Figure 5 ): femur length / width ratio ca 2.0; patella slightly wider than long in retrolateral view; tibia ~ 2 / 3 of patellar length in retrolateral view; retrolateral tibial apophysis ( RTA) strongly sclerotized, bifurcated basally with two slender, hook-shaped rami pointed apically; dorsal tibial apophysis ( DTA) tiny, with pointed tip; cymbium ~ 1.35 × longer than wide; tegulum ~ 1.43 × longer than wide, with small, antero-retrolateral bump (TB); embolus (E) originating at ca 9: 30 o’clock position, curved ventrally at base, and with rather blunt tip.

Female (Fig. 6 A – D, G View Figure 6 ). Total length 2.88. Carapace 1.20 long, 0.73 wide. Abdomen 1.78 long, 0.90 wide. Eye sizes and interdistances: AME 0.24, ALE 0.11, PLE 0.11, AERW 0.63, PERW 0.73, EFL 0.55. Legs: I 1.64 (0.50, 0.28, 0.38, 0.25, 0.23), II 1.38 (0.40, 0.25, 0.30, 0.23, 0.20), III 1.49 (0.45, 0.23, 0.30, 0.28, 0.23), IV 2.11 (0.65, 0.35, 0.45, 0.43, 023). Habitus (Fig. 6 G View Figure 6 ) similar to that of male except darker, and without cluster of dark ventral setae on patellae and tibiae I.

Epigyne (Fig. 6 A – D View Figure 6 ) longer than wide; atrium (At) large, occupying most region of posterior 2 / 5, separated by narrow septum (Se); copulatory openings (CO) almost round, touching each other; copulatory ducts ( CD) tapered into invert infundibuliform on proximal half, then acutely narrowed and forming ca 90 ° curves; spermathecae (S) almost spherical, with posteriorly extending portions.

Distribution.

Known only from the type locality in Xizang, China (Fig. 47 View Figure 47 ).
