Type and type locality. The holotype, deposited at National Museum of Natural History, French ( MNHN 6288), from Vedaranyam, the Southeastern coast of India, on Thryssa mystax (Bloch & Schneider, 1801) .

Material examined. Holotype: 1 ovig. female (26 mm) Vedaranyam, 8 September 2009, from Thryssa mystax , coll. G. Rameshkumar ( MNHN 6288 About MNHN ).

Paratypes: 1 ovig. female (20 mm) Vedaranyam, 08 September 2009, from Thryssa mystax , coll. G. Rameshkumar ( CAS / MBRM C-17 ) .

Nontype: 1 ovig. female (24 mm) Parangipettai, 29 May 2017, from Thryssa mystax , coll. S. Ravichandran (ZSI/MBRC D1-546), the southeastern coast of India.

Remarks. Rameshkumar et al. (2011) provided a detailed diagnosis and description of the type material. Nerocila poruvae can be recognised by coxae 5–7 longer than a segment, much wider and longer than coxae 2–4, with posterior margin acute; lack of posterolateral pereonal processes; ventrolateral margins of pleonites 1–2 strongly produced, posteriorly directed, expending beyond pleonite 5. Pleotelson heart-shaped, longer than wide; pleonites 4 and 5 subequal and longer than 1–3; slender and long pereopods 1–5 with dactyli well-developed; the darkness of posterolateral part of pereon, all pleon and anterior part of pleotelson and uropods. Uropods slender and long, extending largely beyond the distal margin of the pleotelson, exopod much longer than endopod. Some specimens from the RMNH, already reported by Trilles (1979), i.e, female (ovig., 22 mm), West India (RMNH no. 3). Latter, the specimen is designated as N. poruvae by Rameshkumar et al. (2011).

Colour. Body pale tan with coxae 6–7, posterior part of pereonite 7, all pleonites, anterior part of pleotelson and uropods dark ( Rameshkumar et al. 2011).

Size. Ovig. females 20–30 mm ( Rameshkumar et al. 2011).

Distribution. Southeastern coasts of India and Java Sea ( Rameshkumar et al. 2011). A specimen held in the RMNH, labelled from West Indian, host unknown, was already mentioned by Trilles (1979).

Hosts. Record from the type locality, Thryssa mystax (Engraulidae) and Trichiurus lepturus (Trichiuridae) ( Rameshkumar et al. 2011).
