The Amphibulimidae (Mollusca: Gastropoda: Orthalicoidea) from Colombia and adjacent areas Author Borrero, Francisco J. Author Breure, Abraham S. H. text Zootaxa 2011 3054 1 59 journal article 46210 10.5281/zenodo.278895 3498da36-33bd-4135-a475-9c978c7f7abc 1175-5326 278895 Plekocheilus ( Eurytus ) phoebus (Pfeiffer, 1863) Remarks. Studying the lectotype (BMNH 1975143), we noticed that the shape of the shell is unlike other Plekocheilus species. It has an acute spire with the nucleus of the protoconch sunken, the last whorl slightly angulated at the periphery and a bi-colored band below the suture. The protoconch is entirely smooth and it probably belongs to the Orthalicidae (sensu Breure et al. 2010) .
