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).
