Schenkel, 1963 : 221, figs 125a–e (♂♀). Logunov & Marusik 1994 : 184, figs 3–5 (♂). X. amuricus Seyfulina & Mikhailov, 2004 : 251 , figs 1–2 (♂). Type material. Syntypes 2♂ and 1♀ [not examined], text data “Urga = Tsitsikhar, 1896”; data in introduction: “Cn 2, Urga-Zizichar, Mongolei-Mandschurei, Chaffanjon, 1896” which means that syntypes were collected during a long (over 1300 km ) trip from Urga (=Ulaanbaatar) to Tsitsikhar (=Qiqihar). Comments . There is no evidence that male and female syntypes were collected together during the 1300 km trip. While males of this species are very similar to X. insulicola Bösenberg & Strand, 1906 , the syntype female of X. ferrugionoides has an epigyne very different from those of X. insulicola and has a septum like in X. audax (Schrank, 1803) . The septum is lacking in X . insulicola as well as in related species such as X. ephippiatus and X. emertoni Keyserling, 1880 . In our opinion, the syntype males and female are not conspecific. The male was well redescribed by Logunov & Marusik (1994) , although types were not examined. The male of this species may be conspecific with X. davidi , X. excavatus or X. hotingchiehi . Here we refrain from providing synonymies because we have no males and females collected from the same locality. Xysticus ferrudinoides is related to X. insulicola which was originally described from Japan , and is now known also from Russia , China and Korea ( Song et al. 1999 ). The two species differ by the shape of the lower part of the tegular apophysis.
