Taxonomic revision of the genus Cloacina von Linstow (Nematoda : Strongyloidea) from macropodid marsupials.

Abstract

The strongyloid nematode genus Cloacina von Linstow,parasitic in the stomachs of macropodid marsupials, is revised andmorphological taxonomic characters are analysed. Ninety species arerecognised, including 48 which are new. A key to the species is provided.

New species are as follows: C. aedon,C. antigone,C. antiope,C. ares,C. artemis, C. caenis,C. cloelia, C. clymene,C. cybele, C. dindymene,C. dirce,C. dis,C. dryope,C. echidne, C. eileithyia,C. enyo, C. eos,C. epona, C. feronia,C. hebe, C. hecuba,C. hera,C. herceus,C. hermes,C. hestia,C. hypsipyle,C. io, C. ips,C. ixion, C. leto,C. littoralis,C. lityerses,C. maia, C. metis,C. nike, C. niobe,C. papillatissima, C. petronius,C . phaeax, C. phaedra,C. phaethon, C. polyxena,C. polyxo, C. selene,C. themis, C. tyche,C. typhon and C. tyro.

Cloacina clarkae Mawson is treated as a synonym ofC. similis Johnston & Mawson, whileC. vestibulata Johnston & Mawson becomes a synonymof C. obtusa Johnston & Mawson.C. dubia Johnston & Mawson,C. inflataJohnston & Mawson andC. typica (Johnston & Mawson) are treated asspeciesinquirendae. An annotated checklist of parasites and hosts is provided.
