Water Pythons and Australian Olive Python


Vandpytoner og Olivenpyton

1842 Liasis Gray (type species: Liasis mackloti Dumeril & Bibron 1844; see International Commission on Zoological Nomenclature 1988: Opinion 1514)
1849 Lisalia Gray (type species: Liasis olivaceus Gray 1842; syn. Williams & Wallach 1989)
1993 Apodora Kluge (type species: Liasis papuanus Peters & Doria 1878; syn. Reynolds, Niemiller & Revell 2014)
2000 Katrinus Hoser (type species: Liasis fuscus Peters 1873; syn. Kaiser, Crother, Kelly, Luiselli, O'Shea, Ota, Passos, Schleip & Wüster 2013)
Contents: 6 species, of which 3 (50.0%) are endemic.
Endemism: 0% 100%
Remarks: Underwood & Stimson (1990) regarded Liasis as a synonym of Morelia. Kluge (1993) retained Liasis as a valid genus with two species (mackloti, olivaceus), and placed four species (childreni, maculosus, perthensis, stimsoni) in the separate genus Antaresia, one (papuanus) in the new genus Apodora, and another (albertisii) in Leiopython. Most recently, Apodora has been synonymized with Liasis again, and Leiopython has been synonymized with Bothrochilus (Reynolds, Niemiller & Revell 2014).
Distribution: Australia, New Guinea and satellites.
Reported from: Australia (Northern Territory, Queensland [incl. Torres Strait Islands], Western Australia), East Timor, Indonesia (Alor, Biak, Misool, Rote, Savu, Semau, West Timor, Western New Guinea, Wetar), Papua New Guinea (d'Entrecasteaux Islands [incl. Fergusson], Eastern New Guinea).

Liasis dunni

Liasis fuscus

Katrinus fuscus cornwallisius Hoser 2004
1885 Nardoa crassa Macleay (Stimson 1969)

Remarks: McDowell (1975) suggested that the differences between fuscus and mackloti are too subtle to warrant recognition as separate species, but he examined too few specimens to present a detailed analysis. Most authors have retained fuscus as a separate species (e.g., Cogger, Cameron & Cogger 1983; Cogger 1996; O'Shea 1996; Schleip & O'Shea 2010; Lang 2011), whereas others have followed McDowell in treating fuscus as a synonym or subspecies of mackloti (e.g., Kluge 1993; Aplin & Smith 2001; Wilson & Swan 2003). A single record from East Timor (Ferreira 1898) is regarded as doubtful (Lang 2011).
Distribution: Australia (Northern Territory, Queensland [incl. Torres Strait Islands], Western Australia), Indonesia (Western New Guinea), Papua New Guinea (Eastern New Guinea).
