Thaumastus (Paeniscutalus) crenellus ; Ramirez et al. 2003 : 282; Breure and Mogollon 2010: 16. Type locality. "Peru, hacienda de Unigambal". Type material. Not located. Additional material. ANSP 180677, holotype, and ANSP 411182 (1), paratype of Megalobulimus (Microborus) incarum Pilsbry; FMNH 51925, holotype of Strophocheilus (Microborus) tenuis Haas. Diagnosis. See above. Dimensions. Shell height 35, diameter 21 mm ( incarum Pilsbry), respectively 30.1 and 18.8 mm ( tenuis Haas). Distribution. Peru, Dept. Ancash, Shaurama near Huaraz (Pilsbry 1944); ibid., Yungay (Haas 1955); ibid., Carhuaz ; ibid., hacienda Llaguen , Potrero Nuevo; ibid., between Huaraz and Caraz ; ibid., near Colcabamba; ibid., hacienda Damian , Paja; ibid., Pacap; ibid., Tapacocha; ibid, near Cajacay; ibid., N of Chiquian , Aquia (all Breure 1978 ); ibid., 3 km S Macara (Breure, unpublished data); Dept. La Libertad, Unigambal ( Philippi 1867 ); Dept. Lima, Autisha; ibid., near Yanac ; ibid., near Matucana; ibid., near San Bartolome (all Breure 1978 ); ibid., Magdalena (Breure and Mogollon 2010). Ecoregion. Sechura desert [NT1315]. Remarks. This species has been considered as a member of the Strophocheilidae due to its general shell shape, with a relatively low spire ( Pilsbry 1944c , Haas 1955b ). The anatomy and phylogenetic data, however, clearly shows it belongs to the superfamily Orthalicoidea . The mentioning by Schileyko (1999 : 282) of "2 spp." within this genus is erroneous as all described taxa are synonymous.
