• Parabetaeus culliereti Coutiere, 1896, the type species of the genus Parabetaeus Coutiere, 1896, is redescribed and illustrated based on recently collected specimens from southern Japan and Papua New Guinea, and the taxonomic status of the genus Parabetaeus Coutiere is clarified. Parabetaeus culliereti appears to exhibit large variation in the development of the rostrum and orbital teeth. This type of variation has not been previously reported in the family Alpheidae. As a result, the genus Neoalpheopsis Banner, 1953 is synonymized with Parabetaeus, and a new combination, Parabetaeus euryone (De Man, 1910) is proposed. Differences between P. culliereti and P. euryone are also discussed.
