Plekocheilus (Aeropictus) cathcartiae (Reeve, 1848)

(Figs 5 S–U, 9A)

Bulimus cathcartiae Reeve 1848: pl. 42 fig. 265. Type locality: “ New Granada, Prov. Mérida” [Venezuela]. Lectotype BMNH 1975288 (Breure 1979). Plekocheilus cathcartiae (Reeve); Richardson 1995: 324 (references; see remarks).

Material. Norte de Santander, 18 km S of Cúcuta, Carriker leg./1947: USNM 590661.?, Colombia, ex H.C. Fulton: USNM 532645 (as Eurytus cathcartiae Reeve, “cotype”); New Granada: ZMUZ 511654 [not seen], BMNH Acc. no. 1829 (Cuming Colln). Venezuela, Mérida: BMNH 1975288; “ Venezuela,” van Lansberge leg.: RMNH.

Remarks. USNM 590661 is the first record for this species with a precise locality in Colombia, although an elevation cannot be assessed with certainty. However, locations at approximately the stated distance from Cúcuta in a S and SW direction range 400 to under 1500 m. We consider this a low elevation in comparison with other species of P. (Aeropictus); it is also possible that the locality data are not accurate. Richardson (1995) grouped P. cathcartiae (Reeve) and P. quadricolor (Pfeiffer) together with P. veranyi (Pfeiffer) . However, P. veranyi is always smaller than P. cathcartiae and confined to the Mérida area in Venezuela; P. quadricolor is different in shell shape, being more elongate.
