Catoessa gruneri Bowman & Tareen, 1983

Catoessa gruneri . — Aneesh, Helna & Sudha, 2016: 1270–1277, fig. 1f. — Ravichandran, Vigneshwaran & Rameshkumar, 2019: 15, figs 1d–f.

(Misidentification) Joryma brachysoma . —Anandkumar, Rameshkumar, Ravichandran, Nagarajan, Prabakaran & Ramesh, 2017: 55–60, fig. 2f.

Type material. Female holotype, National Museum of Natural History (USNM 191070). For other paratypes see Bowman & Tareen (1983).

Type locality. South of Faylaka, Kuwait Bay, Arabian Gulf .

Type host. From the gills of Aurigequula fasciata (Lacepède, 1803) (formerly Leiognathus fasciatus).

Host. Leiognathidae, Terapontidae and Pristigasteridae: Leiognathus fasciatus [currently Aurigequula fasciata (Lacepède, 1803)] (see Bowman & Tareen 1983), Ilisha melastoma (Bloch & Schneider, 1801), Terapon puta (Cuvier, 1829), Leiognathus daura (currently accepted as Karalla daura) (Cuvier, 1829) and Eubleekeria splendens (Cuvier, 1829) (see Aneesh et al. 2016; Ravichandran et al. 2019).

Distribution. Arabian Gulf, Kuwait (Bowman & Tareen 1983); India (Aneesh et al. 2016; Ravichandran et al. 2019); Malaysia, off the coast of Miri (Anand Kumar et al. 2017).

Remarks. Catoessa gruneri can be readily identified by a pyriform cephalon with rounded rostral tip; pereopods basis without carina; coxae 2–6 shorter than their respective pereonites; pereonite 7 partly to nearly completely overlapping pleonite 1; pleonite 1 narrower than rest of pleon, pleonites 2–5 as wide as pereonite 7; epimera laterally directed; posteriorly narrowed pleotelson; uropods extending to posterior pleotelson end (Ravichandran et al. 2019).

According to Aneesh et al. (2019b), and Anandkumar et al. (2017), the figure of Joryma brachysoma (Pillai, 1964) from the host Netuma bilineata in Sarawak, Malaysia is a misidentification and refers to Catoessa gruneri based on its morphological characteristics.
