Type and type locality. The syntypes of Glossobius auritus Bovallius, 1885 are held at the Swedish Museum of Natural History, Stockholm ( SMNH) ( RMS Isopod no. 4971, 3475 and 3476), from an unknown locality ( Bruce & Bowman 1989).

Remarks. Aneesh et al. (2017a) provided a detailed description of Indian specimen G. auritus . Glossobius auritus can be identified by the rhomboid-like body, cephalon not being immersed in pereonite 1, pereonite 1 with minute anterolateral margins or margins projecting laterally, pleopods with transverse ridges, endopods with weak proximomedial lobes, endopods 2–5 with depressions and expanded posterior margin of pereopods 4–7 bases. The brood pouch of G. auritus formed by 5 pairs of overlapping oostegites arising from the bases of pereopods 1–4 and 6.

Ravichandran et al. (2011) figure of Ceratothoa angulata ( Richardson, 1910) from the host Hyporhamphus dussumieri (Valenciennes, 1847) . But this is a misidentification and refers to Glossobius auritus . The sub-rhomboid body, dark coloration with black anterior becoming lighter toward posterior, pereonite 1 anterolateral margins forming two “bosses” (in reference to prominent lateral lobes) which project laterally, rostrum truncate in dorsal view, pleotelson posterior margin truncate with median emargination, and uropod curving medially with endopod slightly longer than exopod are important characteristics that define the species ( Bruce & Bowman 1989; Martin et al. 2015b).

Dana’s (1853) figures of species referred to the Glossobius crassa (as Ceratothoa crassa ) and the he body shape, pleonites 2–5 width and length, and truncate pleotelson are in agreement with Glossobius anctus Bruce & Bowman, 1989 . As it is impossible to resolve the species identity without thentype specimen, thus the G. crassa was placed into nomen dubium by Martin et al. (2015b).

Distribution. The species has been recorded from the western Pacific: ( Trilles 1973; Bruce & Bowman 1989; Nunomura 1992), Atlantic ( Trilles 1973; Bruce & Bowman 1989; Kononenko 1986) and Indian Ocean ( Trilles 1973; Bruce & Bowman 1989; Ravichandran et al. 2011; Aneesh et al. 2017a).

Host. Glossobius auritus is restricted to beloniform fishes. In most records, the host was not identified; reported host fishes include clearwing flying fish Cypselurus comatus (Mitchill, 1815) ( Bruce & Bowman 1989) , Japanese flying fish Cheilopogon agoo (Temminck & Schlegel, 1846) (see Bruce & Bowman 1989), the Mediterranean flying fish Cheilopogon heterurus ( Kononenko 1986) and Cypselurus angusticeps Nichols & Breder, 1935 (see Nunomura 1992). The Indian material is from Slender Garfish Hyporhamphus dussumieri (Valenciennes, 1847) (see Ravichandran et al. 2011) and large scale flying fish Cypselurus oligolepis (Bleeker, 1865) ( Aneesh et al. 2017a) .
