A new species of Drymaeus endemic from Currais Archipelago, Paraná, Brazil (Pulmonata, Bulimulidae)

Abstract: The new bulimulid species, Drymaeus currais sp. nov., is described based on shell and anatomical features. It is endemic of Guapirá Island, belonging to the Currais Archipelago, a small protected area off Paraná coast. The species is thus, based at least on endemicity, endangered. It has as closest species D. castilhensis, another endemic species of Castilho Island, ~70 km northwards. Its main exclusivities are a banded shell (except for periumbilical area); a ureter ~1/3 opened (furrow); an external anus; a s… Show more

“…The central nervous system (nerve ring) has shown relatively conservative in both genera studied here, all of them are similar (e.g., Fig 24C ), varying only in some small details and proportions, as reported above. At least in its main features, the nerve ring of the studied species is very similar to that of the megalobulimines [ 10 ] and even of the Bulimulidae (e.g., [ 31 ]).…”

“…Luego, se continuó con una línea de corte a través del tegumento dorsal de la cabeza hacia delante de la misma, para descubrir el sistema nervioso central, parte anterior del sistema digestivo y reproductor. A partir de aquí se procedió a separar los sistemas.Particularmente el abordaje del sistema reproductor se realizó siguiendo la terminología propuesta por Simone y Amaral (2018) ySimone et al (2020).Especialmente la delimitación de las partes que componen el complejo peniano se realizó siguiendo la caracterización morfo-histología descripta por Rezende yLanzieri (1964);Lanzieri y Rezende (1965); Van Mol (1971, fig. 13);Breure (1979, fig.…”
