Type material.

Holotype ♂ ( TRU - JS 0729 ), China: • Yunnan Province, Menghai County, Bameng Village (22 ° 08.1 ' N, 100 ° 31.56 ' E, ca 2030 m), 1. VII. 2023, J. X. Liu et al. leg. GoogleMaps

Etymology.

The specific name is a patronym in honor of the collector; noun (name) in the genitive case.

Diagnosis.

Cheliceroides jinxini sp. nov. resembles C. longipalpis in habitus and palpal structure, but can be distinguished by the following: 1) presence of a raised tegular portion (Fig. 1 A, B View Figure 1 ) vs absent (Lin L. et al. 2024 a: figs 9–11, 16); 2) male palpal tibia ~ 1 / 5 of cymbial length (Fig. 1 A, B View Figure 1 ) vs approx. as long as cymbium ( Lin et al. 2024 a: figs 9–11, 16); 3) embolus (E) originating at ca 4 o’clock position (Fig. 1 A, B View Figure 1 ) vs ca 2 o’clock position ( Lin et al. 2024 a: fig. 10); and 4) chelicerae unmodified, and presence of one retromarginal tooth (Fig. 2 D View Figure 2 ) vs modified, and two retromarginal teeth ( Logunov 2021: figs 2, 4).

Description.

Male (Figs 1 View Figure 1 , 2 View Figure 2 ). Total length 5.40. Carapace 2.60 long, 2.04 wide. Abdomen 2.68 long, 1.64 wide. Eye sizes and interdistances: AME 0.64, ALE 0.36, PLE 0.30, AERW 1.96, PERW 1.80, EFL 1.24. Legs: I 5.99 (1.75, 1.08, 1.45, 1.08, 0.63), II 5.12 (1.58, 0.95, 1.18, 0.88, 0.53), III 5.67 (1.83, 0.88, 1.20, 1.13, 0.63), IV 5.89 (1.83, 0.80, 1.28, 1.35, 0.63). Carapace dark except anterior half of thoracic part red-brown, covered with dense dark and white setae, with clusters of bilateral, dense white scales. Chelicerae red-brown, with two promarginal teeth and one retromarginal tooth. Legs overall yellow except femora I dark brown, patellae, tibiae, and metatarsi I yellow-brown, spiny. Dorsum of abdomen yellow laterally, with anterior, transverse, arc-shaped setal stripes, and central, longitudinal, dark patch; venter pale brown, with dark spots.

Palp (Fig. 1 A, B View Figure 1 ): femur length / width ratio ca 3.32; patella slightly wider than long; tibia short, ~ 2 × wider than long in ventral view; retrolateral tibial apophysis ( RTA) broadened into sub-quadrangular portion at base, then tapered to blunt end slightly curved inward; cymbium flat, ~ 1.5 × longer than wide in ventral view; tegulum almost round, with swollen retrolateral portion; embolus (E) long, arising at ca 4 o’clock position, extending circularly (ca 340 °) along tegulum before strongly curving 180 °, then antero-prolaterally extending into acutely pointed tip at apex of cymbium.

Female. Unknown.

Distribution.

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

Comments.

The new species is considered a member of the genus because it shares a series of characters with C. longipalpis , such as the similar habitus, pattern, and long and whip-like embolus. However it is also obviously different from the latter by the unmodified chelicerae with one retromarginal tooth (vs modified, elongated chelicerae with two retromarginal teeth; Logunov 2021: figs 3, 9), the C-shaped sperm duct (vs S-shaped; Logunov 2021: fig. 5), and only the cymbium bears dense white setae (vs all segments except coxae and femora are densely covered with white setae; Logunov 2021: figs 2, 4). Therefore, the generic position of this species remains uncertain. Discovering its unknown female and obtaining enough molecular evidence could be helpful in confirming this issue.
