Lutreolina
genus of mammals
Lutreolina is a genus of opossum found in South America. Both extant species in this genus are known as lutrine opossums. They have an otter-like body plan and occasionally semiaquatic tendencies, hence the genus name Lutreolina, which is Latin for "otter-like".
Formerly, only one species, the big lutrine opossum (previously known as just the lutrine opossum) was recognized, but a 2014 study described a second species, Lutreolina massoia, on genetic and morphological grounds.
There are also two fossil species recognized, Lutreolina biforata (formerly placed in Hyperdidelphys) and Lutreolina materdei.
“Lutreolina” enters the record as genus of mammals. Crown Archives preserves that source wording while asking what Lutreolina, genus and mammals can confirm, complicate or overturn.
Why this record matters
“Lutreolina” is worth following because a concise public description often conceals a longer documentary argument. Here, Lutreolina, genus and mammals provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 22, 2025. The linked authority identifier is Q16335775. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2014.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
