Scutalus phaeocheilus altoensis Breure & Mogollón Avila, 2010
Distribution
Peru
Scutalus phaeocheilus phaeocheilus occurs in south of the Lambayeque Region.
Description
When describing the nominate taxon, Haas already noted the relationship with Scutalus proteiformis. He stated that this species ‘seems to lack the granules entirely’. According to Pilsbry (1897), who copied the original description, the ‘granulation [is] confined to the last whorl’. However, Scutalus phaeocheilus altoensis is smaller and slightly stouter than Scutalus proteiformis and is also slightly more granulose than this species, especially visible in fresh specimens. Moreover, Scutalus proteiformis is said to have the aperture dark brown coloured. Scutalus proteiformis species, which has not been figured, was mentioned by Weyrauch (1967) from northern Peru without further information.
Scutalus phaeocheilus altoensis
The subspecific name altoensis refers to El Alto, the type locality.
Scutalus phaeocheilus altoensis is characterized by the whitish colour, the sculpture of growth striae and inconspicuous granules on the last whorl, the broadly expanded lip and the orange colour of the aperture inside.
The public source identifies “Scutalus phaeocheilus” as species of mollusc. This brief keeps that definition visible, then builds a research path around Scutalus, phaeocheilus and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Scutalus phaeocheilus”, the useful work is to connect “species of mollusc” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Feb 19, 2023. The linked authority identifier is Q7439553. The first chronological checks are 2010, 1897 and 1967.
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.
