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.
