Morphological redescription and neotype designation of Sulcospira paludiformis (Yen, 1939) from Hainan, China

ABSTRACT

Semisulcospira paludiformis, collected from Hainan Island, China, was described by Yen in 1939. While the type specimens of S. paludiformis were destroyed in World War II, the systematic classification of this species has remained dubious because of the lack of further study. In 2015 we collected fresh specimens from near the type locality, based on which we have described the morphology and have designated a neotype. The anatomy shows that the species belongs to the genus Sulcospira Troschel, 1858 (family Pachychilidae).
