Remarks

Compared to the material of Chace (1983), the number of ventral rostral teeth for this species is more variable in our specimens. It ranges from one to seven. Atyopsis spinipes occurs from Philippines and eastern Lesser Sunda Islands (ca. 120 ° 009E) northwards to Taiwan and as far as Tokuno-shima in the Ryukyus, and eastwards as far as Samoa ( Chace 1983).

Distribution

West Pacific.
