| Abstract: | The poorly known alpheid shrimp Betacopsis indicus (De Man), originally described from Lombok, Indonesia, is reported here for the first time: from the waters of Taiwan and northern Australia. Examination of the new material has shown that the monotypic Hamalpheus Bruce & Hiffe, is a junior synonym of Betaeopsis Yaldwyn. Three of the four diagnostic features used to separate Hamalpheus from other alpheid genera, tire present in both B. indicus and the type species B. aequimanus (Dana). These features include the peculiar hook-like spines on the uropods. Betaeopsis, now containing three: species, is redefined, while detailed redescriptions and synonymies are provided for B. aequimanus and B. indicus. The relationships of Betaeopsis to Betaeus Dana are discussed. |
