Glossobius parexocoetii Kononenko & Mordvinova, 1988

Glossobius parexocoetii Kononenko & Mordvinova, 1988: 103 , figs. 1–3.

Type and type locality. The holotype ( ZMMU No.Mc 1033) and paratype ( ZMMU No.Mc 1034) were collected off Conakry, Guinea, from sailfin flyingfish Parexocoetus brachypterus (Richardson, 1846) and deposited at The Zoological Museum of Moscow University ( ZMMU).

Remarks. Glossobius parexocoetii is identified by the subparallel body shape, rostrum subacute, slender antennula and antenna, lack of bulbous lobe on pereonite 1, rounded pleotelson posterior margin and subequal uropod rami.

Kononenko & Mordvinova (1988) provided figures of the antennula, antenna, mouthparts and uropods of the female and male G. parexocoetii type. The female and male share similar morphological characteristics: 3 maxillula setae, 7 antennula segments, 9 antenna segments and subequal uropod rami lengths. The female differs from the male by having: maxilliped article 3 with 2 setae (compared to 1 seta), maxilla with 10 setae (compared to 4 setae), and the article 3 of the mandibular palp is without a setae (compared to 1 seta).

Glossobius parexocoetii differs from G. impressus 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. Reported from the tropical eastern North Atlantic Ocean ( Kononenko & Mordvinova 1988).

Hosts. Reported from Parexocoetus brachypterus ( Kononenko & Mordvinova 1988) .
