Rhadinorhynchidae [1] is a family of parasitic worms from the order Echinorhynchida.

Species

Rhadinorhynchidae has 4 subfamilies (Golvanacanthinae, Gorgorhynchinae, Rhadinorhynchinae, and Serrasentoidinae) and the following species: [2] [a]

Golvanacanthinae Paggi and Orecchia, 1972

Golvanacanthus

GolvanacanthusPaggi and Orecchia, 1972 contains one species:

  • Golvanacanthus blenniiPaggi and Orecchia, 1972

Gorgorhynchinae Van Cleave & Lincicome, 1940

Australorhynchus Lebedev, 1967

Cleaveius Subrahmanian, 1927

Edmondsacanthus Smales, 2009

Gorgorhynchus Chandler, 1934

G. occultus has been found parasitising the Cobbler wobbegong (Sutorectus tentaculatus) in Bunbury, Western Australia. The proboscis of this worm has 18 to 20 rows of 8 or 9 hooks followed by a well-developed neck. The body contains irregular circles of small spines in a single anterior portion. The male reproductive system limited to the posterior quarter of the trunk. There are three cement glands. [3]

R. decapteri is a parasite of the marine fish Round scad (Decapterus punctatus) and is found coastal waters of Brazil. It has 10 longitudinal rows of 22–26 hooks. The species name decapteri was derived from the genus (Decapterus) of the type host. [8]

R. mariserpentis parasitizes the Oarfish, Regalecus russelii and has been collected near Wakamatsu-ku, Kitakyūshū, Japan.

R. trachuri is one of the most widespread acanthocephalans infesting fish from the Eastern Pacific, Western Pacific, and Indian Oceans. On the South pacific coast of Vietnam, it was found infesting the Frigate tuna (Auxis thazard), and the Torpedo scad (Megalaspis cordyla). [13]

Notes

  1. ↑ A binomial authority in parentheses indicates that the species was originally described in a genus other than the present genus.
  2. ↑ Gymnorhadinorhynchus decapteri was combined with Rhadinorhynchus decapteri based on genetic analysis. [10] The original family and genus names are a combination of the Greek word gymnos (naked) and Rhadinorhynchidae/ Rhadinorhynchus , a family/genus of similar morphology, but lacking somatic spines. [8] A phylogenetic analysis had been conducted to confirm that Gymnorhadinorhynchus is a well supported clade within the monophyletic order Echinorhynchida [8] but the new analysis superseded this one. Previously, Gymnorhadinorhynchidae can be distinguished from other families of Echinorhynchida by the combination of the following morphological characteristics: a cylindrical proboscis with longitudinal row of hooks, basal circle of hooks larger than anterior hooks, an absence of trunk spines, asymmetry of hook shape, four cement glands, and a spineless trunk. [9]
  3. ↑ Genetic analysis resulted in the move of Gymnorhadinorhynchus mariserpentis to the genus Rhadinorhynchus [10]
