Xysticus vachoni Schenkel, 1963 Figs 1, 40–42 X. v. Schenkel, 1963: 235, fig. 131 (♂♀). Marusik, 1989: 143 (synonymy with jacuticus ); Ono 2009: 511, figs 138–141 (♂♀). X. jacuticus Utochkin, 1968: 40, figs 126–129 (♂♀). Ono 1988: 81, figs 62–64 (♂). Type material. Holotype ♀ [not examined] with text data “Urga—Tsitsikhar, 1896 ”. Data in introduction “Urga–Zizichar, Mongolei –Mandschurei”. Both labels refer to material collected during a 1300 + km route from Ulaanbaatar (=Urga) to Qiqihar (=Tstsikhar). The type locality may be either in modern Mongolia or eastern Inner Mongolia. Comments. Song et al. (1999) mentioned this species among “ Species inquirendae ” and cited its distribution as Gansu with reference to Schenkel (1963), although the species was described and reported either from eastern Mongolia or eastern Inner Mongolia, far away from Gansu. There are few illustrations of X. vachoni in the literature and therefore we provide figures of this species together with figures of the sibling, X. triangulosus Emerton, 1894, known from the Nearctic. Males of the two species clearly differ by the shape of the ventral tibial apophysis and the shape of the tutaculum. The epigynes in both species are variable in shape, and may appear identical (cf. fig. 703 in Dondale & Redner 1978). : Published as part of Marusik, Yuri M. & Omelko, Mikhail M., 2014, Reconsideration of Xysticus species described by Ehrenfried Schenkel from Mongolia and China in 1963 (Araneae: Thomisidae), pp. 275-289 in Zootaxa 3861 (3) on pages 286-287, DOI: 10.11646/zootaxa.3861.3.5, http://zenodo.org/record/252642 : {"references": ["Schenkel, E.
