Taxonomy and description

Phylogenetic analysis has been conducted.[2]

Species

There are three genera and six species in the family Transvenidae:[3][4][lower-alpha 1][lower-alpha 2]

Paratrajectura Amin, Heckmann et Ali, 2018

  • Paratrajectura longcementglandatus Amin, Heckmann et Ali, 2018

Sclerocollum Schmidt and Paperna, 1978

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

Trajectura Pichelin & Cribb, 2001[1] Trajectura is distinguished by the possession of only two cement glands and an anterior conical projection (function unknown) on the females.[1]

  • Trajectura ikedai (Machida, 1992)

Diplosentis ikedai was found to share similar anatomical features (only two cement glands and an anterior conical projection on females) was renamed T. ikedai.[1]

  • Trajectura perinsolens Pichelin and Cribb, 2001

T. perinsolens Was found parasitising the New Guinea wrasse Anampses neoguinaicus from the Great Barrier Reef, Queensland, Australia.[1]

Transvena Pichelin & Cribb, 2001[1]

  • Transvena annulospinosa Pichelin and Cribb, 2001

Hosts
  • Hosts for Transvenidae species
  • Anampses neoguinaicus swimming
    The New Guinea wrasse (Anampses neoguinaicus) is one of the hosts of T. perinsolens

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[5] including Pararhadinorhynchus magnus.[6] Pararhadinorhynchus is sometimes classified within the Diplosentidae.[6]
