A phrurolithid spider species, Phrurolithus splendidus Song & Zheng 1992, is newly recorded from Japan. This species resembles P. pennatus, but can be distinguished from the latter by male tibial apophysis with thin finger-shaped apex, and spermathecae located behind openings.

We report the occurrence of a gynandromorph of the funnel-web spider Allagelena opulenta collected by a Malaise trap set in a Japanese cedar plantation on Mt. Aikodake, Yakushima Island, Japan. This specimen presents a transverse gynandry, with the anterior half of the body male and the posterior one female. The epigyne is abnormally developed, and the shape of the epigynal opening is deformed compared to that in normal females. This is the first case of gynandromorphy observed in this genus.

A new species of the spider genus Anyphaena (Araneae: Anyphaenidae), Anyphaena yoshitakei sp. nov., is described on the basis of specimens obtained from the Ryukyu Islands, Japan. The male palpal structure of this species is similar to those of males of A. taiwanensis and A. pugil, but this species can be distinguished by the lack of palpal femur spines. The female can be easily distinguished from females of Asian congeneric species by the shape of the longitudinal middle furrow of the epigyne.

A new species of the genus Marpissa (Araneae: Salticidae), Marpissa mashibarai sp. nov., is described using specimens obtained from Yamaguchi and Tokyo Prefs., in Honshu Island, Japan. This species exhibits poorly marked sexual dimorphism in body size and coloration. Both sexes have the black median line on dorsum of abdomen, allowing us to distinguish it from the other congeneric species.
