A new species of Haminoea in Brazilian coast (Cephalaspidea, Haminoeidae) as part of H. elegans group

Abstract

Haminoea maray is introduced as a replacement for what was previously identified as H. elegans, now recognized as a complex comprising several species found on both sides of the Atlantic. This descriptive paper presents a comprehensive phenotypic study based on specimens collected from Ceará to São Paulo, Brazil, and had been previously recognized as a molecular variant. The newly described species inhabits estuarine environments with low salinity, exhibiting distinct conchological and anatomical features compared to other populations of H. elegans and related congeners. https://zoobank.org/936AAD86-91A6-459D-A6ED-9C3DC7F2E8FF.
