Type and type locality. Holotype, ovig. female (22 mm), held at the French National Museum of Natural History ( MNHN 6289 About MNHN ), Muttam, Southwestern coasts of India from Sardinella sp.

Material examined. Holotype: ovig. female (22 mm) Muttam, 09 June 2009, from Sardinella sp. coll. G. Rameshkumar ( MNHN 6289 About MNHN ).

Paratypes: 1 non ovig. female (13 mm), Muttam, 09 June 2009, from Stolephorus commersonnii Lacepède, 1803 , coll. G. Rameshkumar ( CAS / MBRM C- 19). 2 non ovig. females (14, 15 mm), Muttam, 09 June 2009, from Hilsa kelee (Cuvier, 1829) coll. G. Rameshkumar ( CAS / MBRM C- 20) all from southwestern coasts of India.

Non-type: 8 ovig. females (18–22 mm), Mandapam, 18 August 2016, from on Hilsa kelee , coll. P. Vigneshwaran (CAS/MBRM C 240–C 247).

Remark. Rameshkumar et al. (2011) provided a detailed diagnosis and description of the type material. Joryma hilsae has an asymmetrical body twisted to one side (2.1 times as long as greatest width), pereonite 1 produced on each side into slightly bilobed processes reaching the anterior margin of cephalon, posterior margin of pleonite 5 bisinuous. All pereopods are without spines. Pleotelson 1.2 times as wide as long, smoothly rounded with caudomedial lobe, uropods rami equal, mandibular palp with 3 segmented, antenna with 9 articles, maxilliped with 4 recurved spines. Similar to that of other Joryma species, the body twisting of the female is either toward left or right according to their occupation of the branchial cavity respectively.

Colour. Body pale tan with large dark stripes on lateral parts of pereonites 6 and 7 and pleonites 1–5 ( Rameshkumar et al. 2011).

Size. Non ovig. females 13–15 mm; ovig. females 18–22 mm ( Rameshkumar et al. 2011).

Distribution. Known only from the Muttam, Southwestern coasts of India ( Rameshkumar et al. 2011).

Hosts. Known only from the type hosts, Sardinella sp., Hilsa kelee and Stolephorus commersonnii Lacepède, 1803 ( Rameshkumar et al. 2011).
