Plekocheilus (Eurytus) episcopalis auriformis (Da Costa, 1904)

(Figs 9 C, 10H–K)

Strophocheilus (Eurytus) auriformis Da Costa 1904: 5, pl. 1 fig. 1. Type locality: Colombia, Bogotá. Holotype BMNH 1907.11.21.112. Plekocheilus auriformis (Da Costa); Richardson 1995: 303 (references).

Material. Cundinamarca, Valle de Tensa [sic, Tenza, 1500–1700 m], Hno. Apolinar María leg.: ANSP 174434; Cordillera de Bogotá [?], Hno. Apolinar María & V. Guevara leg./1933: ANSP 164576; Bogotá: UMMZ 147714 (partim, ex Tomlin & Caziot).

Remarks. These are the first precise localities for this taxon, which is now considered by us a subspecies of P. episcopalis . Cordillera de Bogotá may refer to the mountainous belt on the eastern side of Bogotá, part of the Cordillera Oriental. This belt is known as Los Cerros Orientales de Bogotá, or Bosque Oriental de Bogotá (2600–3550 m), and is protected by regional legislation. P. episcopalis auriformis differs from the nominate form by (1) the less rounded last whorl; (2) the stronger columellar fold; (3) the ear-shaped aperture. Valle de Tenza is ca. 40 km NE of Gachetá, the nearest record of P. episcopalis corticosus .
