Glossobius hemiramphi Williams & Williams, 1985: 147 , figs. 1–25.— Bruce & Bowman, 1989: 19, figs. 13,14.— Bakenhaster, McBride & Price, 2006: 283, fig. 5.

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 anctus and G. parexocoetii are the most similar species to G. hemiramphi 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. Glossobius parexocoetii differs from G. a n c t u s in having narrower anterior margins of coxae, pleonites posterior margins linear and pleotelson posterior margin rounded.

Bakenhaster et al. (2006) described the annual life cycle and defined terms and characteristics for each developmental phase for G. hemiramphi . Important developmental stages by Bakenhaster et al. (2006) are as follows; embryo (marsupial stage occurring before shedding of embryonic membrane layers; may have limbs; lack distinct appendages); pre-manca or pullus I (first marsupial stage; has distinct appendages; lacks uropodal and pleotelsonic setae); manca or pullus II (final marsupial; free swimming and infective stage; six pairs of spinose pereopods; setose pleopods, uropods and pleotelson); male (reduced pigmentation, penes and pereopods 7 present; lack setation); ovigerous female (bearing marsupiumites).

Distribution. 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).

Hosts. Hemiramphus brasiliensis (Linnaeus, 1758) (see Williams & Williams 1985) and Hemiramphus bermudaensis Collette, 1962 (see Bruce & Bowman 1989).
