This article appears to be a hoax. I can find no evidence for this name in any of the literature, and the sources cited here do not mention the name.

I am very familiar with the taxonomic literature for this group and I am confident the name has no basis in reality. The cited authority, Tate & Archbold (1941), does not include this name. There is a corresponding Wikispecies article that I got deleted; it attributed the name to Laurie (1952) instead, which doesn't include the name either. Neither does it appear in Flannery's (1995) book on the Mammals of New Guinea, Van Dyck (2002) who reviewed this group, Groves (2005) a major taxonomic compendium, Krajewski et al. (2007) a recent paper about this group, or the American Society of Mammalogists' Mammal Diversity Database.

I found two online references to the name:

• A forum thread that references xenochromus as a subspecies.
• A picture on Commons that purports to be the holotype of xenochromus. However, specimen BMNH 1911.11.29.10 is actually the holotype of Phascogale venusta rubrata (=Neophascogale lorentzii), a different New Guinea dasyurid (BMNH catalog). If you zoom in on the picture, you can indeed see a handwritten label Phascogale venusta rubrata.
  • Edit: The picture is an altered copy of commons:File:Speckled dasyure (Neophascogale lorentzii) .jpg, with the name edited and the colors changed. Ucucha (talk) 20:16, 27 January 2023 (UTC)[reply]

• Comment I deleted this file on Commons as fake. All other images were deleted as copyvios by another admin. Yann (talk) 21:51, 28 January 2023 (UTC)[reply]

• Delete I've dug quite deep now, and it appears that every mention of the name on the web can ultimately be traced back to WP. Note, the taxon was also present at Dasyuridae, inserted by the same author [1], before being removed last December [2]. One peculiar exception: the forum thread linked above predates WP appearance of the name by three years. Still, overall it sure does look like a hoax. --Elmidae (talk · contribs) 12:24, 28 January 2023 (UTC)[reply]

  @Elmidae Does this cast doubt on that author's other uploads to Commons? See https://commons.wikimedia.org/wiki/Special:Contributions/Big_baboon_272 🇺🇦 Fiddle^Timtrent Faddle^Talk to me 🇺🇦 13:04, 28 January 2023 (UTC)[reply]

I would say it does, but maybe Ucucha may be placed to identify these guys by habitus? --Elmidae (talk · contribs) 13:46, 28 January 2023 (UTC)[reply]

I wouldn't be confident identifying these, as many of these dasyurids look quite similar and I don't have experience with the animals themselves, only their names, but based on the pictures in Flannery (1995) the identifications look solid. For example, Murexia rothschildi indeed has a broad black stripe, and Murexia melanurus has a yellow rump and black tail.

I'm a bit skeptical about the sourcing for these images though, given what we now know about the author. They claim the pictures were own work, but these are hard-to-find tiny mammals living in a remote place (New Guinea); there aren't a lot of people who really would be able to have pictures of them in the wild. So we should seriously investigate the possibility that the pictures were taken from somewhere else. Notice that commons:File:Murexia_habbema.jpg has an "(a)", suggestive it was part of a multi-part figure in some source. The most likely candidate would probably be the marsupial volume of Handbook of Mammals of the World, but I don't own a copy so can't check. Ucucha (talk) 13:59, 28 January 2023 (UTC)[reply]

Actually, found the source. I'll continue this discussions over on Commons. Ucucha (talk) 14:03, 28 January 2023 (UTC)[reply]

• Delete should never have been accepted at AfC as the sources are not about claimed subject. I can find no evidence of existence and the manipulated image shows this is clearly a deliberate hoax. KylieTastic (talk) 15:04, 28 January 2023 (UTC)[reply]

Anyone got the energy to go through the rest of the users edits as I'm sure well find more issues - unless they were not the origin of the hoax but took this from another source that was the hoax. KylieTastic (talk) 15:08, 28 January 2023 (UTC)[reply]
