Description
Trochosa adjacens O. Pickard-Cambridge, 1885
Fig. 10C
Trochosa adjacens O. Pickard-Cambridge, 1885: 83 (♀).
Type: holotype ♀ in OUMNH, vial “## faded label, 1680”. Information in the text “Yangihissar, April 1874 ” (= China, Xinjiang).
Note. This species was recognized among the “Yarkand spiders”, a collection lacking species or geographical labels, due to its size, “over 5 lines” (~ 10.5 mm), and pale coloration. In the description, O. Pickard-Cambridge (1885) compared this species with T. terricola Thorell, 1856 and T. ruricola, the generotype.
Description. See O. Pickard-Cambridge (1885). Holotype faded. Measurements of the holotype ♀: total length 11.0; carapace 5.0 long, 4.0 wide; Leg I 11.7 (3.3, 1.9, 2.6, 2.3, 1.6).
Comments. The shape of the epigyne indicates that this species belongs to Trochosa, unlike other species placed by O. Pickard-Cambridge (1885) in this genus. The relationship of T. adjacens with other congeners remains unclear. Most, if not all, females in the genus Trochosa cannot be distinguished from each other, especially singletons. To correctly classify this species, males are required from the type locality.
Distribution. This species is known from the type locality only, Yangihissar Town in SW Xinjiang.
