A new species of the micro snail genus Heleobia (Caenogastropoda, Cochliopidae) from Bahia, Brazil

Abstract

The prey of a recent described characid fish, so far endemic of the small lake Pratinha (Iraquara, Bahia, Brazil), a small (~2.5 mm) lentic gastropod, revealed to be a new (possible endemic) species. It is herein formally described as Heleobia brucutu sp. nov. The description includes anatomical features, revealing interesting idiosyncrasies such as egg laying attached to shell, and penis lacking glands, but with terminal papilla. The new species appears to be endemic of that small lake as much as its fish predator. As the species is now formally described and named, protective efforts must be implemented.

Stapafurdius, a new genus of Bulimulidae (Mollusca, Eupulmonata) from Bahia, Brazil, with two new species

“…30). This present discovery joins several recent ones describing new species and even new genera (e.g., Simone, 2013, in press;Simone & Oliveira, 2021;Simone & Salvador, 2021), showing how weak is the knowledge on the Brazilian malacofauna. Possibly protective efforts must be implemented to preserve such species and environments.…”
