Abstract

Life Sciences & Biomedicine Marine & Freshwater Biology Science & Technology Zoology
Phylogenetic analyses confirm the monophyly of a group of Drymaeus s.l. species that are characterised by tones of bluish or greenish colours of their bodies. This group is now considered as Antidrymaeus L. Germain, 1907, which was recently elevated from synonymy to generic status. Species of this group have been found from Florida to Brazil and Peru, but further fieldwork may show that more species belong to this genus than hitherto known. The following new taxa are described: Antidrymaeus multifasciatus nevisensis Robinson & Breure and Antidrymaeus multifasciatus luciae Robinson & Breure. The genus Antidrymaeus now includes A. dormani (W.G. Binney, 1857), A. gereti (C.M.F. Ancey, 1901), A. immaculatus (Reeve, 1850), A. inusitatus (Fulton, 1900), A. multifasciatus christopheri (Pilsbry, 1899), A. multifasciatus laticinctus (Guppy, 1868), A. multifasciatus luciae Robinson & Breure, 2024, A. multifasciatus multifasciatus (Lamarck, 1822), A. multifasciatus nevisensis Robinson & Breure, 2024, A. pinchoti (Pilsbry, 1930), A. stramineus (Guilding, 1824), and A. sulphureus (L. Pfeiffer, 1857). Additionally, several species of Drymaeus Albers, 1850 and Mesembrinus Albers, 1850 that also have bluish or greenish colours in their body are treated here. The hypothesis is posed that these also might be members of Antidrymaeus; however, this can only be corroborated through future phylogenetic studies.
