Glossobius hemiramphi Williams & Williams, 1985: 147 , figs 1–25.— Bruce & Bowman, 1989: 19, figs 13, 14.— Bakenhaster, McBride & Price, 2006: 283, fig. 5.— Martin, Bruce & Nowak, 2015b: 345–346. Aneesh, Helna, Sudha, & Anilkumar, 2017a: 3–17, figs 7–14 .

Type and type locality. The holotype ( USNM 213532), allotype ( USNM 213533) and paratypes ( USNM 213534– 213541) were collected offshore Guanica Bay, Puerto Rico from host ballyhoo Hemiramphus brasiliensis ( Linnaeus, 1758) and are deposited at The National Museum of Natural History, Smithsonian Institution, Washington.

Remarks. Glossobius hemiramphi is identified by the subparallel body shape; rostrum subacute, antennula and antenna stout, lack of bulbous lobe on pereonite 1, pleotelson posterior margin emarginate and broad carinae on pereopod 7 basis.

Glossobius hemiramphi is most similar with G. anctus and Glossobius parexocoetii Kononenko & Mordvinova, 1988 in having a subparallel body shape, antennula and antenna stout, and similar uropod morphology. Glossobius hemiramphi differs from G. anctus in having broader anterior margins of coxae, posterior margins of pereonites 1–7 deeply concave, and a rounded rostrum; G. parexocoetii differs from G. hemiramphi in the less prominent lateral lobes on pereonite 1, pereonite 4 subrectangular, pleonites 1–5 with concave posterior margins, antenna with 9 segments (compared to 8 segments), and pleotelson posterior margin rounded ( Kononenko & Mordvinova 1988).

Distribution. This species distributed from Western Atlantic to Indian Ocean. Western Atlantic: Georgia, Florida, Bermuda, Bahamas, Haiti, Puerto Rico, Virgin Islands, Yucatan Peninsula, Mexico; Eastern Atlantic: Dakar, Senegal, Angola, Liberia, Sierra Leone, Guinea, Ghana (see Bruce & Bowman 1989) and Indian Ocean: Malabar Coast, India (see Aneesh et al. 2017a).

Hosts. Known only from the family Hemiramphidae : Hemiramphus brasiliensis ( Linnaeus, 1758) (see Williams & Williams 1985), Hemiramphus bermudaensis Collette, 1962 (see Bruce & Bowman 1989) and Hemiramphus lutkei Valenciennes, 1847 (see Aneesh et al. 2017a).
