Paradeontacylix sanguinicoloides McIntosh, 1934

Host species: Seriola hippos Günther, 1876 (Carangidae) .

Locality: Greenly Island, offshore from Port Lincoln , South Australia (34º38’29’’S, 134º47’28’’E) .

Site: Heart.

Infection details: number of infected fish = 1; prevalence 25%; intensity 1; host sizes 1160 FL (1120–1160 FL, n = 4). This Samson fish was also parasitised by a Paradeontacylix sp. (see below).

Material deposited: 1 voucher specimen SAMA AHC 28910.

Previous records: S. lalandi : blood vessels of the gills, Atlantic Ocean, off Miami, Florida, USA (holotype: USNPC 34329, McIntosh 1934); heart, Sir John Young Banks, New South Wales, Australia (34º56’52’’S, 150º55’45’’E) (voucher: SAMA AHC 28909, Diggles & Hutson 2005).

Remarks

The single specimen of P. sanguinicoloides from S. hippos in South Australia and a single specimen recovered previously from S. lalandi in New South Wales (see Diggles & Hutson 2005) were identified following McIntosh (1934) and from digital images of the holotype provided by the USNPC. The specimen of P. sanguinicoloides from S. hippos in South Australia shared characters with the holotype including 4 posterior longitudinal rows of large tegumental spines each comprising 3 rose­thorn­shaped spines, a maximum number of 14 marginal tegumental spines per row and a large testicular field relative to total body length. An accurate count of testes could not be determined for this specimen. Shared characters between the holotype and the specimen of P. sanguinicoloides from S. lalandi in New South Wales included a maximum number of 14 marginal tegumental spines per row, a large testicular field relative to total body length and 60 testes. In contrast to the type specimen and the specimen of P. sanguinicoloides from S. hippos , the specimen of P. sanguinicoloides from S. lalandi had an extra posterior spine in each row i.e. 4 posterior longitudinal rows of large tegumental spines each comprising 4 rose­thornshaped spines. Table 1 presents a comparison of important morphological characters between the original report of P. sanguinicoloides by McIntosh (1934) and the specimens reported here.
