Source-derived summary

The Michoacan pocket gopher (Zygogeomys trichopus) is a species of rodent in the family Geomyidae. It is monotypic within the genus Zygogeomys. It is endemic to Mexico where its natural habitat is temperate, high-altitude forests. Its numbers are declining and it is listed by the IUCN as "endangered".

Description

The Michoacan pocket gopher is a small animal with short, dense, black, lustrous fur and a hairless tail. The eyes are small and deep-set and there is a pad-like region of bare skin just behind the nostrils. It is docile when caught, making no attempt to bite as do other pocket gophers.

Distribution and habitat

The Michoacan pocket gopher is endemic to the Trans-Mexican Volcanic Belt mountain range in central southern Mexico, where it occurs in four discrete locations near west of Lake Pátzcuaro at altitudes over 2,200 metres (7,200 ft). The fossil record shows that members of the genus Zygogeomys, including two other now extinct species, were widespread in the late Pliocene epoch in the southwestern United States. Its typical habitat is mixed forests of spruce, pine, and alder with deep friable soil suitable for burrowing.

Editorial summary

The public source identifies “Michoacan pocket gopher” as species of mammal. This brief keeps that definition visible, then builds a research path around Michoacan, pocket and gopher.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 186-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Michoacan, pocket and gopher providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Michoacan pocket gopher”, the useful work is to connect “species of mammal” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 26, 2026. The linked authority identifier is Q973229. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
