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

Type and type locality. The holotype, deposited at National Museum of Natural History, Smithsonian Institution ( USNM 191070), from South of Faylaka, Kuwait Bay (Persian gulf).

Remarks. Catoessa gruneri can be identified by the body symmetrical, lateral margin of pereon nearly parallel; cephalon pyriform, narrowed anterior to eyes, reflexed ventrally into rounded lobe separating antennula; coxae 2–6 much shorter than their pereonites, coxa 7 only slightly shorter; pleonite 1 partly to nearly completely overlapped by pereonite 7, narrower than rest of pleon; pleonite 1 partly to nearly completely overlapped by pereonite 7, narrower than rest of pleon, pleonites 2–5 about as wide as pereonite 7; epimera directed laterally, narrower than central parts of pleonites, more or less separated from one another by gaps; rounded rostral point and posteriorly narrowed pleotelson; pereopods have without carina on basis; pleonites 2–5 subequal in width, epimera directed laterally; uropods reaching posterior end of pleotelson.

The subsequent reports of Joryma brachysoma are either misidentification or unconfirmed records; Anandkumar et al. ’ s (2017) figure of Joryma brachysoma ( Pillai, 1964) from the host Netuma bilineata (Valenciennes, 1840) is a misidentification and refers to C. gruneri based on the morphology.

Distribution. Recorded from the Arabian Gulf, Kuwait ( Bowman & Tareen 1983) and most recently reported from the southwest coast of India ( Aneesh et al. 2016a).

Hosts. Recorted from Leiognathus fasciatus (Lacepède, 1803) , Ilisha melastoma (Bloch & Schneider, 1801) (as Ilisha indica ), Terapon puta Cuvier, 1829 (as Therapon puta ), Leiognathus daura (Cuvier, 1829) ( Bowman & Tareen 1983) and Eubleekeria splendens (Cuvier, 1829) ( Aneesh et al. 2016a) .
