Comments on snails of the genus Zoniferella from Ecuador (Mollusca: Achatinidae)

The genus Zoniferella includes six taxa of land snails from Colombia and Ecuador, for which little has been published beyond their original descriptions. In this paper, we present new records of Zoniferella vespera (Jousseaume, 1887), expanding its range across northwestern Ecuador. We provide the first description of the colouration in life for Zoniferellasnails. We comment on the taxonomy of some species of Zoniferella, recognising the synonymy of Z. riveti (Germain, 1907) with Z. vespera but calling for further integrative taxonomic analyses before recognising further synonyms between species of the genus.
