Source-derived summary

The visored bat, (Sphaeronycteris toxophyllum), is a bat species from tropical South America. It is the only species in the genus Sphaeronycteris. Although visored bats have some unique characteristics, they are thought to be most closely related to little white-shouldered bats and wrinkle-faced bats.

Description

Visored bats range from 52 to 63 millimetres (2.0 to 2.5 in) in head-body length. They have greyish-brown fur becoming paler towards the front of the body, grey or brownish-white underparts, and white spots on each shoulder and just below the ears. They have a rounded head, with a short, hairless, snout, a wide mouth, and bulging golden-brown eyes. The ears are triangular, with a narrow tragus. Their most distinctive feature, however, is the presence of the "visor" for which they are named - a structure not found in any other bat species.

The visor consists of a horny outgrowth above and behind the horseshoe-shaped nose-leaf. In females it is a relatively small ridge-like structure, and located above the centre of each eye, from where it connects to a central ridge behind the nose-leaf.

Editorial summary

Begin with the source’s own compact description: “Visored bat” is species of mammal. The dossier treats that line as a proposition to test through Visored, species and mammal, not as a finished interpretation.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 179-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Visored, species and mammal is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of mammal” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 6, 2026. The linked authority identifier is Q332153. None of the 0 selected statements returned an explicit reference.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
