Ordo: Stylommatophora
Familia: Orthalicidae
Genus: Quechua
Name
Quechua olmosensis (Weyrauch, 1967) stat. n. – Wikispecies link – Pensoft Profile
- Thaumastus (Quechua) salteri maximus Weyrauch 1967[1]: 347, fig. 135; Ramírez et al. 2003[2]: 282; Barbosa et al. 2008[3]: 272; Breure 2012a[4]: 10.
- Thaumastus (Quechua) maximus; Neubert and Janssen 2004[5]: 217, pl. 2 fig. 13.
Type locality
“Norte de Perú interandino, Peña Blanca, en el camino de herradura de Sócota a San Andrés, 25 km NE Cutervo, 2600 m”.
Type material
SMF 156381, holotype.
Additional type material
FML 3202 (1), paratype.
Diagnosis
Differs from the nominal taxon by the larger size and the darker aperture.
Dimensions
Shell height 99.4, diameter 47.3 mm.
Distribution
Peru, Dept. Cajamarca, Peña Blanca.
Ecoregion
Peruvian Yungas [NT0153], Marañon dry forests [NT0223].
Remarks
This taxon was described as a subspecies of Quechua salteri (Sowerby III, 1890); Neubert and Janssen (2004)[5] considered it as a distinct species. Upon comparison with both the types from Quechua salteri and Quechua olmosensis (Zilch, 1954), it appears very similar in its external morphology to the latter, and quite distinct to the former. Given the difference in size and the dislocation of the type locality, Weyrauch’s taxon is now considered as Quechua olmosensis maxima (stat. n.).
