Type material. Female syntype, Rijksmuseum von Natuurlijke Historie (RMNH n. 12; see Ravichandran et al. 2019) .

Type locality. Eastern Indonesia, Amboina (Bleeker 1857) .

Type host. Host type unknown.

Host. Various species: [ Thryssa mystax, Otholithus ruber, Serranus sp., Pellona indica, Therapon jarbua and Sardinella fimbrita (west coast of India), Carangoides malabaricus, Ilisha melastoma, Olithes ruber (southeast coast of India), Selaroides leptolepis, Terapon puta, Opisthopterus tardoore and Pomadasys maculatus (see Ravichandran et al. 2019)].

Distribution. Indian Ocean: Arabian Sea (Chidambaran & Menon 1945), Persian Gulf (Bowman 1978), Bay of Bengal (see Ravichandran et al. 2019), Red Sea and northern Indian Ocean (Bruce 1982), Pacific Ocean: (see Bowman 1978), East Malaysia (Miers 1880).

Remarks. Nerocila sundaica has cephalon anterior margin narrowly rounded or with an indistinct medial point; pereonite 7 posterolateral corners produced backward into pointed process, reaching to pleonite 5 anterior margin; uropod exopod tilted inward, full width, and not seen from dorsal view; endopod reaching or extending slightly beyond pleotelson posterior margin.

Bowman (1978) redescribed this species in great detail, and it is one of the most common Indo-Pacific species of Nerocila . Rameshkumar et al. (2015, 2016) reported the prevalence of Nerocila sundaica from the host Olithes ruber on two separate occasions, with a prevalence of 42.2 % and mean= 1 in 2015, and another separate record in 2016 with a prevalence of 26.08 % and mean= 1.

Bruce (1987b) examined the type material for Nerocila laevinota Miers, 1880, and concluded, without giving detailed remarks, that it was a junior synonym of N. sundaica .
