Type material. Xysticus davidi : 4 ♀ syntypes [examined], one herewith designated as a lectotype and the epigyne dissected: “Mus Paris, Kion-Kiang a. David 1198-74”. Text data: “Kiukiang, V 1873: 1 ♀” indicates only one specimen. Data in introduction “Dd 5 Kiu-kiang, Kiangsi”—which refers to modern Jiangxi Province, Jiujiang.

Xysticus excavatus : holotype ♀ [examined] with dissected epigyne: labels: “Potanin 43”, “43” and “Потанинъ” which refer to: Gansu “Kloster Kadigel” 26.05.1885. Text data “Kloster Schine... Sume, Ordos, 9 IX 84: 1 ♀” which refers to Potanin’s number 10.

Xysticus hotingchiehi : holotype ♀ [examined] without legs, only with left femur I, abdomen separated from prosoma, epigyne dissected; vial label “Wuchang Ho Tingthich”. Text data “Wuchang, 1937: 1 ♀”. Data in introduction: “Wu - Wuchang, Hupei, Mr. Ho-Ting-Chich, 1937” (=Wuhan, Hubei Privince).

Xysticus pentagonius : holotype ♀ and paratype ♀ [examined] from ZMMU, RUSSIA, Amur Area, Tambovski Distr., Muraviovka Park, July 2001 (R. Seyfulina).

Comments. All synonymised species have the same shape of epigyne, are of a similar size and have similar markings. It is possible that this species is conspecific either with X. ferruginoides Schenkel, 1963 or X. insulicola Bösenberg & Strand, 1906 .

Xysticus ferruginoides was described on the basis of both sexes, but the female was mismatched and the true female remains unknown. Additional evidence that X. ferruginoides can be a senior synonym of X. davidi comes from fact that the holotypes of Xysticus amurensis Seyfulina & Mikhailov, 2004 (♂, = ferruginoides ) and X. pentagonius Seyfulina & Mikhailov, 2004 (♀, = X. davidi ) were collected in the same locality. Because 1) female of X. ferrugionoides is unknown, 2) epigyne and vulva of X. insulicola were not properly illustrated, 3) type localities of X. davidi and X. hotingchiehi lie in coastal areas, while the type locality of X. excavatus lies in mountains, there is a possibility that X. davidi and X. hotingchiehi can be synonyms of X. insulicola , but that X. excavatus can be a synonym of X. ferruginoides .
