HOSTS AND LOCALITIES: Infesting Synalpheus hastilicrassus Coutière, 1905 , S. tumidomanus tumidomanus (Paul’ son, 1875) ( Alpheidae ), Indonesia (?), Andaman Islands, Hong Kong, 2–9 fathoms (= 3.7–16.5 m).

REMARKS: Markham (1985a) transferred the type species of Paraphrixus , Phryxus subcaudalis Hay, 1917 , to Eophrixus , synonymizing the two genera. However, Markham (1990, 1992a) continued to use the combination Paraphrixus brevicauda while admitting (1990) that “ Paraphrixus is no longer a valid name, but revision of the genus is not appropriate here.” It is clear that, based on current data, Hemiarthrus brevicauda must be placed in Eophrixus , as this is the genus with which it shares the most characters and, as a synonymized genus, it cannot be used as a valid name. Rediscovery of E. brevicauda is desirable in order to determine whether it really belongs in Eophrixus , as Chopra’ s (1923) description is incomplete and the type specimens are inaccessible.
