Popis: Galathea amboinensis De Man, 1888 and G. inflata Potts, 1915, both known as associates of shallow water co- matulid crinoids, are reported for the first time from Japan. In the Ryukyu Is­ lands, Galathea inflata was found on 13 species of crinoids but most commonly on Comanthus parvicirrus (Miiller) and Comaster schlegelii (Carpenter). Gala­ thea amboinensis was recorded from 10 crinoid species but more often on Capil- laster multiradiatus (Linnaeus) than on other crinoids. Heterosexual pairs of G. inflata were found on 26.3 % of host crinoids (n=57), and all females were ovigerous. Megalopae of both galatheids were found on hosts, indicating that the larvae settled on crinoids at the megalopa stage.
