Type material.

Holotype ♂ (IZCAS-Ar40604), China: Yunnan: Xishuangbanna, Mengla County, Menglun Town, Menglun Nature Reserve, Xishuangbanna Tropical Botanical Garden, tropical rainforest (21°55.20'N, 101°16.21'E, ca 550 m), 30.04.2019, Y. Tong et al. leg. Paratype 1♂ (IZCAS-Ar40605), same data as holotype.

Etymology.

The specific name refers to the inflated femur of the male palp; adjective.

Diagnosis.

Chinattus inflatus sp. nov. resembles C. wengnanensis Cao & Li, 2016 in the general shape of the habitus and male palp but can be easily distinguished by the inflated palpal femur, the femoral apophysis and the long embolus. The new species also resembles species of the genus Grayenulla Żabka, 1992 by the inflated palpal femur and the femoral apophysis but can be distinguished by leg III, which is one of the shortest legs rather than distinctly the longest as in species of Grayenulla . Additionally, the clypeus lacks bristles, whereas there are three central bristles in species of Grayenulla ( Żabka 1992).

Description.

Male (Figs 3 , 4 ). Total length 2.72. Carapace 1.53 long, 1.14 wide. Abdomen 1.19 long, 0.92 wide. Clypeus 0.10 high. Eye sizes and inter-distances: AME 0.36, ALE 0.21, PLE 0.17, AERW 1.13, PERW 1.08, EFL 0.57. Legs: I 2.82 (0.85, 1.12, 0.46, 0.39), II 2.38 (0.73, 0.85, 0.41, 0.39), III 2.65 (0.85, 0.85, 0.56, 0.39), IV 2.75 (0.88, 0.85, 0.63, 0.39). Carapace brown, dark in eye field, bearing white, thin setae on the lateral submargin, and golden, thin setae on the cheeks and cephalic region. Clypeus dark. Fovea longitudinal, short, bar-shaped. Chelicerae red-brown, with two promarginal teeth and one retromarginal fissident. Endites, labium and sternum paler than chelicerae. Legs red-brown to dark brown, with pale rings on femora and metatarsi. Abdomen suboval, dorsum brown, speckled, with three pairs of irregular white spots and two pairs of muscle depressions; venter darker than dorsum, with a pair of off-white longitudinal bands laterally and a pair of dotted lines medially.

Palp (Fig. 3A-D ): femur inflated, more than 1.5 times longer than wide, with a subtriangular retrolateral apophysis proximally; tibia wider than long, with a sclerotized, short RTA extending towards the bulb in retrolateral view and almost completely hidden by the bulb in ventral view; posterior lobe well-developed, with oval margin; embolus flat and straight, tapered to a pointed tip.

Female. Unknown.

Distribution.

Known only from the type locality in Yunnan, China.

Comments.

The species is placed into this genus because it generally resembles C. wengnanensis Cao & Li, 2016. It is described only based on males, and so there is a possibility that it is conspecific to one of the congeners known only from females.
