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.
