Remarks. Cymothoa selari is most readily identified by the acute anterolateral margins of pereonite 1; the free cephalon (anterolateral projections not touching the cephalon); the rounded rostrum; short uropods; and large carina on the basis of pereopod 7. Avdeev (1978) described C. selari from the Red Sea, comparing it to the South American species C. ianuarii and C. brasiliensis. Cymothoa selari was subsequently recorded from Madagascar but without specific data or illustrations (Trilles 2008). This record increases the geographical range of this species substantially. We were unable to locate or obtain type material for this species during the course of this study for a redescription or comparison to Trilles’ (2008) material. Hosts. Selar crumenophthalmus (Bloch, 1793) (previously as Caranx crumenophthalmus) (see Avdeev 1978; Trilles 1979). Distribution. Known from the Red Sea (Avdeev 1978; Trilles 1979) and Madagascar (Trilles 2008).Published as part of Hadfield, Kerry A., Bruce, Niel L. & Smit, Nico J., 2013, Review of the fish-parasitic genus Cymothoa Fabricius, 1793 (Isopoda, Cymothoidae, Crustacea) from the southwestern Indian Ocean, including a new species from South Africa, pp. 152-176 in Zootaxa 3640 (2) on page 164, DOI: 10.11646/zootaxa.3640.2.2, http://zenodo.org/record/21957

Type and type locality. The holotype Cymothoa bychowskyi, held at Russian Pacific Federal Fisheries Research Institute, Vladivostok (TINRO АGK 75011) from northwestern Australia, red cornetfish Fistularia petimba Lacépède, 1803. Material examined. 1 ovig. female (27 mm), Agatti Island, Lakshadweep, 20 April 2011, from Strongylura leiura (Bleeker, 1850), coll. G. Rameshkumar (CAS / MBRM C- 87). Reamarks. Cymothoa bychowskyi can be identified by the body 2.4 times as long as wide; pereonite 1 with broad anterolateral margins reaching half the length of cephalon; coxae 2–4 posteroventral margins rounded, coxae 5–7 posteroventral margins project laterally in dorsal view; pleonites subequal in length, pereonite 7 posterolateral margin extending to pleonite 4; pleotelson posterior margin rounded; uropods not extending beyond posterior margin of the pleotelson and pleopod 2 of female holotype with an appendix masculine. Avdeev (1979a) originally described C. bychowskyi from Australia and included information on the male specimen. Avdeev (1979a) made a comparison to C. parupenei Avdeev, 1979a and also mentioned the deposition of the paratypes at TINRO (AGK 75012 –75021). Cymothoa bychowskyi is currently known to parasitise only the red cornetfish, Fistularia petimba and occurs in a small geographical range. This species has only been collected least and would require more collections for a more informative analysis. Cymothoa bychowskyi has high host specificity and the infrequent reports would suggest low occurrence. Rameshkumar et al. (2013) reported 7.9% prevalence (3 of 38 hosts) of the species from Agatti Island, Lakshadweep, southeastern India. Distribution. Northwestern and Western Australia, precise locality not given (Avdeev 1979a; Kensley 2001). Also reported from Guam, Micronesia (Williams et al. 2000), Okinawa, Japan (Williams et al. 2000), Lakshadweep and India (Rameshkumar et al. 2013). Hosts. Known only from family Fistulariidae: Fistularia petimba, Lacepède, 1803, (see Avdeev 1979a; Williams et al. 2000; Rameshkumar et al. 2013d) and bluespotted cornetfish Fistularia commersonii Rüppell, 1838 (Williams et al. 2000).Published as part of Ravichandran, S., Vigneshwaran, P. & Rameshkumar, G., 2019, A taxonomic review of the fish parasitic isopod family Cymothoidae Leach, 1818 (Crustacea: Isopoda: Cymothooidea) of India, pp. 1-99 in Zootaxa 4622 (1) on pages 18-19, DOI: 10.11646/zootaxa.4622.1.1, http://zenodo.org/record/337989

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).Published as part of Ravichandran, S., Vigneshwaran, P. & Rameshkumar, G., 2019, A taxonomic review of the fish parasitic isopod family Cymothoidae Leach, 1818 (Crustacea: Isopoda: Cymothooidea) of India, pp. 1-99 in Zootaxa 4622 (1) on pages 23-24, DOI: 10.11646/zootaxa.4622.1.1, http://zenodo.org/record/337989

Type material. Holotype: ovig. ♀ (28 mm), off northwestern Australia, from red cornetfish Fistularia petimba Lacépède, 1803 (TINRO АGK 75011). Paratypes: 4 ovig. ♀ (TINRO АPK 75012 –75015), 1 non-ovig. ♀, (TINRO АPK 75016), 4 mature ♂ (TINRO АPK 75017 –75020), 1 immature ♂ (TINRO АPK 75021); same data as holotype. Remarks. No material of this species was examined. A loan request for the types was made, but the specimens could not be located. Cymothoa bychowskyi can be identified by the body 2.4 times as long as wide; pereonite 1 with broad anterolateral margins reaching half the length of cephalon; coxae 2–4 posteroventral margins rounded, coxae 5–7 posteroventral margins project laterally in dorsal view; pleonites subequal in length, pereonite 7 posterolateral margin extending to pleonite 4; pleotelson posterior margin rounded; uropods not extending beyond posterior margin of the pleotelson and pleopod 2 of female holotype with an appendix masculina (0.7 times as long as pleopod 2 exopod length). Avdeev (1979 a) briefly compared C. bychowskyi to C. parupenei Avdeev, 1979 a. Both species have a subtruncate cephalon, and are widest at pereonite 5. Cymothoa bychowskyi is distinguished from C. parupenei by the elongate body, 2.4 times longer than wide (compared to the 1.7 longer than wide body in C. parupenei); anterolateral margins of pereonite 1 projecting forward (compared to the broader anterolateral margins of pereonite 1 curved mesially towards cephalon), and the rounded posterior margin of pleotelson (compared to the subtruncate posterior margin of C. parupenei). Cymothoa bychowskyi has high host specificity and the infrequent reports would suggest low occurrence. Rameshkumar et al. (2013) reported 7.9 % prevalence (3 of 38 hosts) of the species from Agatti Island, Lakshadweep, southeastern India. Distribution. Northwestern and Western Australia, precise locality not given (Avdeev 1979 a; Kensley 2001). Also reported from Guam, Micronesia (Williams et al. 2000), Okinawa, Japan (Williams et al. 2000) and Lakshadweep, India (Rameshkumar et al. 2013). Hosts. Known only from family Fistulariidae: Fistularia petimba, previously Fistularia villosa Klunzinger, 1871 (see Avdeev 1979 a; Williams et al. 2000; Rameshkumar et al. 2013) and bluespotted cornetfish Fistularia commersonii Rüppell, 1838 (Williams et al. 2000).Published as part of Martin, Melissa B., Bruce, Niel L. & Nowak, Barbara F., 2016, Review of the fish-parasitic genus Cymothoa Fabricius, 1793 (Crustacea: Isopoda: Cymothoidae) from Australia, pp. 1-72 in Zootaxa 4119 (1) on pages 6-7, DOI: 10.11646/zootaxa.4119.1.1, http://zenodo.org/record/25850

Avdeev’s (1979 a) illustration of the ovigerous female also included: simple maxillula, with 3 terminal setae; lateral lobe of maxilla partly fused to mesial lobe, with 1 and 2 recurved setae on mesial lobe and lateral lobe respectively; weakly segmented maxilliped, terminal article 3 with 2 recurved setae; pleopod 2 with appendix masculina present, exopod bigger than endopod, convex endopod mesial margin, distally rounded, deeply convex lateral margins, without proximal margins extending beyond peduncle. Cymothoa rotunda is similar to C. hermani and C. borbonica from the subtriangular cephalon and rounded pleotelson posterior margin (and bulbous ornamentation in C. hermani). Cymothoa hermani differs from C. rotunda from the less rounded body, 1.8 to 1.9 times longer than wider (compared to the 1.4 times longer than wide body), dorsally visible coxae and trisinuate posterior margin of pleonites 2–5. The female paratype of C. hermani has 4 robust setae on the maxillula and pleopod 2 without an appendix masculina (Hadfield et al. 2011) compared to the 3 robust setae on maxillula and pleopod with an appendix masculina of C. rotunda (Avdeev 1979 a). Cymothoa borbonica does not have the unique bulbous ornamentation on pereonite 1, body sub-parallel, pleonites not subequal in width, and coxae 2–7 posteroventral margins acute and dorsally visible. Distribution. Western Australia (Avdeev 1979 a); known only from the original description. Hosts.

Endopod 3.0 times as long as greatest width, apically rounded, lateral margin weakly convex, terminating without setae, mesial margin straight. Colour. Light brown in ethanol (present study), ivory white in Rameshkumar et al. (2013). Remarks. Cymothoa parupenei can be identified by the wide anterolateral margins on pereonite 1 extending beyond the anterior margins of cephalon; semi-circular cephalon anterior margin (subtruncate cephalon in holotype); pleonite 1 almost entirely overlapped by pereonite 7; uropods reaching posterior margin of the pleotelson; pereopod 7 basis with smooth and moderately raised carina, ischium inferior distal margin with slight bulbous projection; and pleotelson 2.1 times wider than long (2.6 times wider than long in holotype). Avdeev’s (1979 a) illustration of the ovigerous female showed a maxillula with 3 terminal setae; lateral lobe of maxilla partly fused to mesial lobe, with 1 recurved seta on each mesial and lateral lobe; a weakly segmented maxilliped, terminal article 3 with 3 recurved robust setae; pleopod 1 rami of subequal size; endopod mesial margin deeply oblique and distally straight, lateral margins deeply convex, with proximal margins extending beyond peduncle. The male pleopod 2 (illustrated by Avdeev 1979 a, fig. 5) has an appendix masculina half the exopod length; exopod lateral margin weakly convex, with medial margin distally rounded and weakly convex. Cymothoa parupenei resembles Cymothoa oestrum (Linnaeus, 1758) in the semi-circular cephalon, pereonites 1–6 posterior margin smooth and pleonites 3–5 becoming progressively wider. Cymothoa oestrum differs from C. parupenei in having anterolateral margins of pereonite 1 that project forward (compared to the more broad and concave anterolateral margins of C. parupenei) and pereopods 5–7 basis have sharp carinae visible in lateral view (see Thatcher et al. 2003) compared to blunt carina of Avdeev’s (1979 a) specimens. Cymothoa parupenei is host specific to Mullidae and has an Indo-Pacific distribution, whereas C. oestrum is known from a variety of fishes and has a western Atlantic distribution (Thatcher et al. 2003).

Cymothoa epimerica Avdeev 1979
No full textCymothoa epimerica Avdeev, 1979 (Fig. 5 A–D) Cymothoa epimerica.— Bruce, Lew, Ton & Poore, 2002: 175.— Hadfield, Bruce & Smit, 2013: 157.— Martin, Bruce & Nowak, 2016: 10, figs 3–8. Cymothoa pulchra.— Yu & Li, 2003a: 228, fig. 5; 2003b: 267. Type material. Female holotype, Russian Pacific Federal Fisheries Research Institute, Vladivostok (TINRO АGK 75023) (Martin et al. 2016). Type locality. Indian Ocean off Australia (Martin et al. 2016). Type host. Malabar blood snapper Lutjanus malabaricus (Bloch & Schneider, 1801) (Martin et al. 2016). Material examined. 2 ovig. ♀ (range: 3.92 mm TL, mean: 20.27 mm TL; range: 3.7 mm W, mean: 9.18 mm) (UMT Crus 01164, 01165), 5 mature ♁ (range: 1.6 mm TL, mean: 13.34 mm TL; range: 1.79 mm W, mean: 5.45 mm W) (UMT Crus 01166, 01169, 01167, 01168, 01170), 4 juveniles ♁ (range: 2.1 mm TL, mean: 8.02 mm TL; range: 0.96 mm W, mean: 3.32 mm W) (UMT Crus 01171, 01174, 01172, 01173); leg 4, ST 121, EEZ, 04º 19’ 38” N; 103º 43’ 50” E, 18 June 2016 via bottom trawl. Host. Host species were not recorded by the SEAFDEC expedition crew; previously recorded from the family Serranidae: Epinephelus coioides (Hamilton, 1822) (Martin et al. 2016) and family Lutjanidae: Lutjanus malabaricus (Bloch & Schneider, 1801) (Avdeev 1979a). Distribution. Australia, Northern Territory (Martin et al. 2016); South China Sea, Peninsular Malaysia (present material). Remarks. Cymothoa epimerica is here newly recorded for Malaysian waters and identified by ovoid body; subtriangular cephalon deeply immersed in pereonite 1; pereonite 1 anterolateral margins deeply curved towards cephalon; pereopods 5–7 superior proximal margin with acute carinae, dorsally visible; coxae 6 and 7 posteroventral margins acute, dorsally visible (Martin et al. 2016) (not as prominent in Cymothoa eremita or Cymothoa pulchrum). Cymothoa epimerica and C. curta with similarly ovoid body, pleotelson posterior margin rounded and cephalon immersed in pereonite 1. Cymothoa curta differs from C. epimerica in small, acute anterolateral pereonite 1 margin; posterolateral coxae margins rounded, not dorsally visible; pereopod 6 basis superior proximal margin rounded; pereopod 7 basis highly raised, broad; uropodal rami broader than C. epimerica, uropod apices rounded; smooth mesial and lateral pleopod 1–5 margins (Martin et al. 2016). Cymothoa epimerica from Seychelles (SMF-76) and the Red Sea (SMF-567 and SMF-572) without host association or illustrations has been documented by Trilles (2008), who briefly mentioned the similarities between Cymothoa epimerica and Cymothoa curta.Published as part of Martin, Melissa B., Tuah, Alia, Muhamad, Juariah H. & Bruce, Niel L., 2022, A review of the family Cymothoidae (Isopoda: Cymothooidea) infesting marine fishes from Malaysian waters, with new host and geographical records, pp. 1-36 in Zootaxa 5222 (1) on pages 9-10, DOI: 10.11646/zootaxa.5222.1.1, http://zenodo.org/record/745638
