Altitudinal range. The few confirmed precise localities give an available range of 1800-2400 meters.
Ecology. Occurring in Cauca Valley and Magdalena Valley montane forests ecoregions. Collected in secondary rain forest, on moss-covered tree trunks (San Antonio de Prado, Antioquia).
Remarks. Mousson described Bulimus trivittatus without figuring it; L. PFEIFFER (1874 [1870-1876]: pl. 130 figs 3-4) figured it for the first time. The type material in Zurich is probably lost (E. Neubert, pers. comm.). This species was hitherto only known by the original description, until NEUBERT & JANSSEN (2004) located a possible syntype. The SMF specimen is not completely in agreement with L. Pfeiffer's figure; the shells on which L. Pfeiffer based his figures are probably lost (DANCE 1966, but see RICHLING & GLAUBRECHT 2008). On the basis of L. Pfeiffer's figures, we tentatively refer the material listed above in this taxon. Relatively constant in shape, specimens vary significantly in colouration, some specimens having a predominant pattern of dark concentric bands over a light background, whereas in other specimens the axial colour bands are more pronounced than the concentric pattern.
Body colouration olive green on the side of mantle and foot, increasingly darker dorsally; sole and eye-stalks lightly coloured (beige). The material from Cauca is tentatively assigned to this taxon, as this locality is substantially farther south than the rest of the available records, mainly in Central Colombia; however, we cannot observe any differences when comparing this material with the shells from Cundinamarca, and further collecting is needed to resolve this disjunct distribution. See also BORRERO & BREURE (2011: 3) for comments on Wallis' localities. The record by PiLSBRY (1898 [1897-1898]: 246) for Bogota was supposedly based on material from Wallis, but the latter author did not give Bogota as a locality, and we have not been able to locate this material. The locality near Laguna de Pedro Palo (ICNB 3519) shows specimens that could be interpreted as intermediates between Drymaeus (D.) smithii and D. (D.) felix. A lot (DMNH 183910, six shells from "Bogota"), labeled as D. felix, is not this species. Relying on museum databases, LINARES & VERA 2012:186 listed additional lots from Bogota, which belong to several other species; they also listed records from localities in Meta, near Villavicencio, that we consider different at the subspecific level (see below).
