Abstract:
Glossobius Schiœdte & Meinert, 1883 is currently one of the most species-poor and yet most variable isopod genera parasitizing marine fishes. The genus was recently redefined and revised by Bruce & Bowman (1989) and more recently by Martin et al. (2015), and now contains eight species (WoRMS, 2018). To date, two species of the genus have been reported from Indian waters, namely, Glossobius auritus Bovallius, 1885 and Glossobius hemiramphi Williams & Williams, 1985 (cf. Aneesh et al., 2017). Recently, a cymothoid isopod identifiable as Glossobius impressus (Say, 1818), was collected in Indian waters. This collection constitutes the first Indian record of G. impressus, also from a new host, the Coromandel flyingfish Hirundichthys coromandelensis (Hornell, 1923) (Pisces: Exocoetidae), which is the third species of this isopod genus known from the country. In this note, the specimen is briefly described, and the known hosts and geographical records of the species are reviewed. A key to the three species of Glossobius from India is also given.
