‘OEDOTHORAX’ TRILINEATUS SAITO, 1934 INCERTAE SEDIS

Oedothorax trilineatus Saito, 1934: 311 , pl. 13, fig. 18, pl. 15, fig. 61 (Df).

Oedothorax trilineatus, Saito, 1959: 79 , fig. 84a–c (f).

Material: Japan: Nemuro , 4♀, leg. S. Motoda, 15.vii.1931, not examined. No type material was designated .

Diagnosis:

Females: This species can be distinguished by the black prosoma, the black opisthosoma with three oblique white markings at the sides, and the white/ black annulated legs and palps.

Males: unknown

Distribution: Japan: Nemuro.

Remarks: According to Saito (1934), this species has prosoma and opisthosoma uniformly black in colour, and legs are white annulated with black, different from the yellow to dark-brown coloration of Oedothorax and Mitrager species. Furthermore, according to his description, three out of four specimens have leg II as the shortest leg, in comparison to leg III as the shortest leg in Linyphiidae in general. Therefore, this species is most likely not a linyphiid.
