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 .
