Taxonomy and description

Phylogenetic analysis has been conducted.[1]

Species

There are three genera and six species in the family Transvenidae:[2][3][lower-alpha 1][lower-alpha 2]

Paratrajectura

Paratrajectura Amin, Heckmann et Ali, 2018 contains one species:

  • Paratrajectura longcementglandatus Amin, Heckmann et Ali, 2018

Sclerocollum

Sclerocollum Schmidt and Paperna, 1978 contains three species:

  • Sclerocollum robustum (Edmonds, 1964)
  • Sclerocollum rubrimaris Schmidt and Paperna, 1978
  • Sclerocollum saudii Al-Jahdali, 2010

Trajectura

Trajectura Pichelin & Cribb, 2001[6] contains two species: Trajectura is distinguished by the possession of only two cement glands and an anterior conical projection (function unknown) on the females.[6]

  • Trajectura ikedai (Machida, 1992)[7]

Diplosentis ikedai was found to share similar anatomical features (only two cement glands and an anterior conical projection on females) was renamed T. ikedai.[6]

  • Trajectura perinsolens Pichelin and Cribb, 2001

T. perinsolens Was found parasitising the New Guinea wrasse Anampses neoguinaicus from the Great Barrier Reef, Queensland, Australia.[6]

Transvena

Transvena Pichelin & Cribb, 2001[6] contains one species:

  • Transvena annulospinosa Pichelin and Cribb, 2001

Hosts

Notes

  1. A binomial authority in parentheses indicates that the species was originally described in a genus other than the present genus.
  2. Pararhadinorhynchus Johnston & Edmonds, 1947[4] including Pararhadinorhynchus magnus.[5] Pararhadinorhynchus is sometimes classified within the Diplosentidae.[5]
