Arhythmacanthidae ia a family of parasitic worms from the order Echinorhynchida.[1]

Species

There are 8 genera in the family Arhythmacanthidae which contains the following species:[2][a]

Acanthocephaloides Meyer, 1932

  • Acanthocephaloides claviformis Araki & Machida, 1987

Found off Japan. The proboscis has 14 rows each of 6 hooks and 2 spines and the trunk has an anterior swelling. The apical hooks are the smallest; posterior hook largest, reaching up to 74 um. Hook and spine roots (when present) invariably simple, posteriorly directed, without manubria. Trunk spines markedly smaller, with variable distributionSpines on the trunk are only on the anterior side.[3]

  • Acanthocephaloides cyrusi Bray, Spencer-Jones & Lewis, 1988

A. cyrusi has been found parasitizing the fish: Blackhand sole (Pegusa nasuta referred to by its synonym Solea bleekeri) and the Small-spotted grunter (Pomadasys commersonnii) in Lake St. Lucia, Natal, South Africa. It is distinguished from the other species in the genus Arhythmacanthidae by the more greater sexual dimorphism in length, differing arrangement of hooks, the proboscis with the longest hooks at the anterior-most part and the larger size of proboscis hooks and body spines.[4] Specifically, the proboscis hook rows with 3 spines and 3 hooks that increase in size anteriorly. Apical hook reaches 83–101 or 118–137 um in length and has root with large, oblique, anterior manubrium. Posterior spines rootless. Whole trunk with regular transverse rows of uniform, acuminate, 13–22 um long spines.[3]

  • Acanthocephaloides delamuri (Parukhin, 1989) Amin, 2013
  • Acanthocephaloides distinctus Golvan, 1969

Found off Senegal.[3]

  • Acanthocephaloides geneticus (Buron, Renaud & Euzet, 1985)

Found off the Mediterranean coast of France.[3]

  • Acanthocephaloides ichiharai Araki & Machida, 1987

Found off Japan. The proboscis has variable 13–14 (rarely 12 or 16) hook rows of 10–12 hooks/spines (9 hooks and 3 rootless spines in 1 specimen). Hook and spine roots (when present) invariably simple, posteriorly directed, without manubria with the apical hook being the smallest; posterior hook largest, and reaching up to 74 um. The trunk is cylindrical and has spines only on the anterior portion smaller than probiscus hooks and variable in their distribution.[3]

  • Acanthocephaloides irregularis Amin, Oğuz, Heckman, Tepe & Kvach, 2011[3]

A. irregularis is found parasitizing the Combtooth blenny (Parablennius zvonimiri) in the Gulf of Odessa, Ukraine, the Mushroom goby (Ponticola eurycephalus) in the Sukhyi Estuary, in the Black Sea, and the Tubenose goby (Proterorhinus marmoratus) and Black-striped pipefish (Syngnathus abaster) in both locations. The species is named for its irregular distribution of trunk spines. A. irregularis is most similar to its closest relative, A. propinquus in proboscis shape and armature as both have 12 longitudinal rows of 5 hooks each and the shape of the trunk, reproductive system and lemnisci. A. irregularis differs from A. propinquus in having randomly distributed trunk spines that are organised in circular rings of individual spines separated by aspinose zones. A. irregularis is also unique in having an anterior trunk collar, a very large triangular cephalic ganglion, nucleated pouches at the posterior end of the proboscis receptacle, and hooks and spines with roots bearing anterior manubria. It is the tenth species of the genus to be described.[3]

S. kostylewi was found parasitizing Solea vulgaris in the bay of Gemlik, Turkey. The body was between 7404 and 7854 µm long and 739 and 1040 µm wide. The anterior part of the body was wider than the posterior. The proboscis was cylindrical and armed with 16 rows of hooks each with 5 or 6 hooks the longest hooks being in the middle of the proboscis. The smallest basal spinelike hooks were unrooted. The testes were located centrally in the body distant from the six cement glands. The eggs measured between 42 – 64µm long and between 12 and 20µm wide.[5]

  • Solearhynchus soleae (Porta, 1905)[b]

S. soleae was found parasitizing Solea vulgaris in the bay of Gemlik, Turkey. The body was from 5382 to 20328 µm long and 693 to 1200 µm wide. The proboscis was from 224 – 320 µm long and the proboscis sac was between 277 and 480 µm long. The proboscis has 12 – 14 rows of hooks each comprising 5 or 6 hooks. The longest hooks were in the middle of the proboscis and the smallest basal hooks were unrooted and resembled spines. The lemnisci were longer than the proboscis sac, measuring between 312 and 350 µm and between 312 – 349 µm long. Males had two testes in the posterior part of the body distant from six piriform cement glands. The eggs measured between 56 and 68 µm long and between 12 and 20 µm wide.[5] This species was also recorded in the Black Sea by Belofastova and Korniychuk (as the synonym Acanthocephaloides rhytidotes).[5] The species name soleae derives from the genus name of the host, the Adriatic sole (Originannly named Solea impar, now named Pegusa impar).[5]

Notes

  1. ^ A binomial authority in parentheses indicates that the species was originally described in a genus other than the present genus.
  2. ^ Solearhynchus soleae, was originally described as Echinorhynchus soleae by Porta in 1905 and re-described by Meyer in 1933 as Acanthocephaloides soleae. De Buron and Maillard later (1985) placed it in the genus Solearhynchus.[5]
