Laevapex vazi is a species of small, freshwater, air-breathing limpet, an aquatic pulmonate gastropod mollusc or micromollusc in the family Planorbidae, the ram's horn snails and their allies.
[1] The species name honours Dr. Jorge Faria Vaz of the Superintendency of Control of Endemic Diseases (SUCEN) of the state of São Paulo.
[2] At the time of the original species description its characteristic features of a smooth shell apex and an ejaculatory complex without a flagellum fitted better in the description for the genus Laevapex; however, the species is in need of taxonomic revision for the establishment of its true identity, since its shell and musculature do not fit in the characteristics of the genus.
The apex is rounded, slightly projected and bent to the right, reaching the edge of the shell or extending beyond it.
The protoconch shows a shallow apical depression and appears smooth under optical microscopy.
