摘要：

An aquatic hydrobiid cavesnail from Andes Mountains of Colombia and Ecuador is described (Andesipyrgus sketi, new genus, new species). The genus is placed in the Cochliopinae based on females having a sperm tube separated from the glandular gonoduct. Diagnostic features of Andesipyrgus include a minute, near-pupiform shell with thickened aperture; unpigmented animal (except for eyespots); reduced ctenidium; female genitalia featuring complex histology of glandular gonoduct, oviduct coiled onto right side of albumen gland, and absence of seminal receptacle; and male with simple, slender penis. Andesipyrgus does not closely resemble other cochliopinids having a simple penis, and appears remotely related to other South American hydrobiid fauna.
