Size. Present material: Ovigerous female: 35 – 15 mm (mean= 23.3 mm, N= 63), pre-ovigerous female: 26 mm, mature male: 8–29 mm (mean= 22.3 mm, N= 27), immature male: 6–16 mm (mean= 11.9 mm, N= 24). Remarks. Ceratothoa imbricata can be identified by the rhomboid body shape with pereonites 1–4 progressively increasing in width, each pereonite with straight lateral margins; pereonites 5–7 progressively decreasing in width, each pereonite with convex lateral margins, convex anterolateral margins of pereonite 1, posterior margins of pereonites dark brown, and pleotelson narrower than pereonite 7. Ceratothoa imbricata is most similar to C. banksii and C. trigonocephala , all three species with the antennula more stout than the antenna, pereonite 1 anterolateral margin pronounced or narrow, broad carina on pereopods 5– 7 basis and uropods extending to or slightly beyond the pleotelson margin. C. imbricata can be distinguished from C. trigonocephala by the rhomboid-shaped body (narrow subparallel body shape in C. trigonocephala ); pleonite and pleotelson width similar or less than pereonite 7 and darker colouration on the posterior regions of the pereonites. The holotype of Ceratothoa banksii has body proportions 1.6 times as long as greatest width (2.1 times as long as greatest width in C. imbricata and 2.4 times as long as greatest width in C. trigonocephala ), a rough dorsal surface and subtruncate pleotelson posterior margin. Ceratothoa trigonocephala has a distinctly subtriangular cephalon anterior margin, narrow and elongated body (pereonite 2–4 similar length), and subparallel body lateral margin. The differences mentioned for the above three species are those of ovigerous females and such body proportions very greatly according to the reproductive state of the female. Ceratothoa imbricata is host specific to Trachurus declivis and Trachurus novaezelandiae (family Carangidae) whereas C. banksii occurs on several host taxa (see section on C. banksii ). The preferred hosts and geographical distribution of C. trigonocephala remain unknown (Hadfield et al . 2014 a). Cymothoa approximans White, 1847 was recorded from Calcutta, without description, drawing, or hostassociation and is a nomen nudum . Miers (1884) regarded Cymothoa approximans as a junior synonym of Ceratothoa imbricata . It is here excluded from synonymy as there is no further information about this species. Hurley (1961) in a footnote compared Filhol’s (1885) figures of Ceratothoa huttoni with Hale’s (1926) description of C. imbricata and considered that the species were the same. After reviewing Filhol’s (1885) drawings of C. huttoni , the distinctive rhomboid-shaped body and small pleotelson confirms this species as a junior synonym of C. imbricata . Avdeev’s (1979 a) drawings of C. trillesi are similar to the holotype illustrations of Hadfield et al . (2014 a) and our present non-type material, showing characteristics of the pleotelson being narrower than pereonite 7, strong carina on pereopod 7 basis, body lateral margins subparallel from pereonites 1–3 and an increase from pereonites 4 and 5, relative decrease of width from pereonite 6 and 7. We requested a loan of the type material of C. trillesi , but the specimen could not be located. Avdeev’s (1979 a) description, illustrations, and the host association with Trachurus declivis nonetheless support a synonymy with C. imbricata . Adult female specimens (MTQ W 34276) from Coquimbo from the host Trachurus murphyi are morphologically identical to the Australian specimens of Ceratothoa imbricata . Avdeev (1992) postulated that C. gaudichaudii and C. trigonocephala ( C. trigonocephala illustrations in Avdeev (1992) are here identified as C. imbricata ) had transoceanic distributions, with both species using the host genus Trachurus . Trachurus murphyi is known to occur from South America to the Tasman Sea and off South Island, New Zealand (Avdeev 1992). Figures for C. gaudichaudii given by Szidat (1966) and Avdeev (1992) are also in agreement with the holotype of C. imbricata and the Australian material examined herein and identified as C. imbricata . Ceratothoa gaudichaudii is here regarded as species inquirenda (p. 36). C. imbricata is known to occur on the host Trachurus murphyi from the eastern Pacific. Codonophilus argus Haswell, 1881 was described from a manca from the bell of the jellyfish Rhizostoma Cuvier, 1800 from Port Jackson (Haswell 1881) and from the jellyfish Catostylus mosaicus (Quoy & Gaimard, 1824; as Crambessa mosaica Haeckel, 1880). Codonophilus argus was later synonymised with Ceratothoa imbricata by Hale (1926). Identification of a manca to species level is nearly impossible without an associated adult female, and the association with a jellyfish as a host is likely to be accidental. We have here excluded Codonophilus argus from synonymy until further verification of the species is made (i.e. molecular identification). Distribution. Present material from Australia: Port Lincoln, South Australia; Port Jackson, Cape Jervis, Broken Bay, Pyrmount and Caloundra, New South Wales; Wilson’s Promontory, Victoria; Tasman Sea and St. Helens, Tasmania. Previous reports include New Zealand (Fabricius 1775; 1793). Hosts. Present material was taken from Trachurus declivis and Trachurus novaezelandiae . Previous accounts have reported C. imbricata on Trachurus declivis (Hale 1926, 1929; Stephenson 1976; Avdeev 1979 a; Maxwell 1982; Hooper 1983; Hine et al. 2000), Trachurus novaezelandiae (Hewitt & Hine 1972; Stephenson 1976; Hine et al. 2000); Trachurus mccullochi (Hooper 1983).
