Type material.
Holotype ♂ (SWUC -T-LIN-38-01); China, Hunan Province, Changsha City, Yuelu District, Yuelu Mountain, 28°11'33.9"N, 112°56'17.52"E, a. s. l. 208 m, 27.IX.2017, Wang Luyu leg.
Etymology.
The specific epithet is derived from Latin adjective “ denticulatus ” meaning “toothed”, referring to the tegulum apically toothed in the male palp.
Diagnosis.
This new species resembles Weintrauboa yele Hormiga, 2008 in having similar embolus in male palp (Fig. 1 A – D; Hormiga 2008, figs 2 A – C, 3 A – C; Hormiga et al. 2021, fig. 6 A, B), but can be differentiated by the tegular apophysis with teeth in W. denticulata sp. nov. (Fig. 1 B, D; vs teeth absent); embolic process tip grooved in ventral view in W. denticulata sp. nov. (Fig. 1 D; vs hook-shaped); embolic flap like in retrolateral view in W. denticulata sp. nov. (Fig. 1 B; vs almost wing-shaped); proximal ramus of cymbial process two times longer than distal one in W. denticulata sp. nov. (Fig. 1 D; vs both rami almost same in length).
Description.
Male (holotype, Fig. 6 A) total length 5.63. Carapace 2.86 long, 2.23 wide; opisthosoma 2.77 long, 2.13 wide. Eye sizes and interdistances: AME 0.17, ALE 0.16, PME 0.17, PLE 0.14; AME – AME 0.10, AME – ALE 0.09, PME – PME 0.14, PME – PLE 0.16, ALE – PLE contiguous. MOA 0.91 long, front width 0.62, back width 0.51. Clypeus height 0.27. Chelicerae brown, with three promarginal and three retromarginal teeth. Leg measurements: I 11.6 (3.08, 1.11, 2.58, 3.23, 1.60); II 10.96 (2.95, 1.02, 2.53, 3.12, 1.34); III 8.41 (2.47, 0.79, 1.84, 2.32, 0.99); IV 10.26 (2.88, 0.88, 2.45, 2.88, 1.17). Leg formula: 1243.
Palp (Fig. 1 A – D). Patella as long as tibia, ventrally grooved, dorsally with long thick spine. Tibia cone-shaped, with one retrolateral trichobothrium, retrolateral margin with seven thick spines. Cymbium with an ectal process wider than long, with bifurcated tip, proximal ramus hook-shaped, two times longer than distal one with pointed end, distal ramus tongue-shaped with blunt end; retrolateral margin of cymbium with tongue-shaped projection extending ventrally with blunt tip. Paracymbium bowl-shaped, apically hook-shaped, with median margin edge curved inward. Tegulum large, apically with long tegular apophysis with seven teeth, tip membranous. Conductor membranous, as long as patella, present on apical end of tegulum. Embolus circular with fine tip, embolic flap rod-like slightly curved with blunt tip, embolic process sclerotized, apically tip grooved, parallel to tegular apophysis.
Female. Unknown.
Distribution.
Known only from the type locality, Hunan, China (Fig. 7).
