Type and type locality. The holotype Cymothoa parupenei ( TINRO AGK 75026) were collected from northwestern Australia ( Avdeev 1979a) from Parupeneus spilurus (Bleeker, 1854) but the specimen could not be located.

Material examined. 2 ovig. females (22, 27 mm), Nagapattinam, 23 April 2013, from Upeneus sulphureus Cuvier, 1829 , coll. G. Rameshkumar ( CAS / MBRM C- 101– C- 102). 1 ovig. female (25 mm), Parangipettai, 29 July 2017, from Upeneus sulphureus , coll. S. Ravichandran ( ZSI / MBRC D1-533 ) . All localities from the state of Tamil Nadu, southeast coast of India .

Remarks. Martin et al. (2016) redescribed and diagnosed C. parupenei from the female paratype (TINRO АPK 75027). Cymothoa parupenei can be recognized by the subrectangular body; wide anterolateral margins on pereonite 1 extending beyond the anterior margins of cephalon; semi-circular cephalon anterior margin, frontal margin rounded to form blunt rostrum; pleonite 1 almost entirely overlapped by pereonite 7; uropods reaching posterior margin of the pleotelson; Pleotelson 0.5 times as long as anterior width, anterior margin not trisinuate, lateral margin weakly concaved, posterior margin subtruncate and irregular, without median point. pereopod 7 basis with smooth and moderately raised carina, ischium inferior distal margin with slight bulbous projection.

Figures given by Martin et al. (2016) of the male showed a coxae 2–7 with rounded posteroventral margins; pleonites posterior margin moderately irregular; pleonites 3–5 progressively wider; pereopods 3–5 similar to pereopod 2, gradually increasing in size, without robust or simple setae; exopod extending past endopod, 3.6 times as long as greatest width, apically rounded, lateral margin straight, terminating without setae, mesial margin weakly straight. The ovig. female pleopod 1(illustrated by Avdeev 1979a) has rami of subequal size with the endopod mesial margin deeply oblique and distally straight, lateral margins deeply convex, with proximal margins extending beyond peduncle.

Cymothoa parupenei can be distinguished from C. indica in having weakly developed or undeveloped amphicephalic processes of pereonite 1. Cymothoa parupenei is host specific to Mullidae and has an Indo–Pacific distribution, whereas C. indica is known from a variety of fishes and has a Pacific and Indian Ocean distribution ( Martin et al. 2016). Martin et al. (2016) reported that the C. parupenei resembles Cymothoa oestrum ( Linnaeus, 1758) in the semi-circular cephalon, pereonites 1–6 posterior margin smooth and pleonites 3–5 becoming progressively wider.

Colour. Light brown in ethanol ( Martin et al. 2016), ivory white in live specimen.

Size. Ovig. females: 22–27 mm.

Distribution. Cymothoa parupenei distributed in northwestern Australia ( Avdeev 1979a; Kensley 2001; Martin et al. 2016) and India ( Rameshkumar et al. 2013d).

Hosts. Known from family Mullidae : Parupeneus spilurus ( Avdeev 1979a) and sulphur goatfish Upeneus sulphureus ( Rameshkumar et al. 2013d) .
