Key Points

A new species, Ostracolethe penevi, was identified in North Vietnam, expanding the knowledge of local biodiversity.
The study confirms the validity of Ostracolethe fruhstorfferi and discusses its unique torus-toroid structure.
A comprehensive key for identifying helicarionoid genera aids in the classification of slugs and semi-slugs.
This research emphasizes the ecological significance of the superfamily helicarionoidea in their natural habitat.

Abstract

A list of species of slugs and semi-slugs of the superfamily Helicarionoidea collected in North Vietnam in 2023 is presented. A new species of the genus Ostracolethe Simroth, 1901, Ostracolethe penevi Dedov & Vu, sp. nov. , is described, which was collected from a single locality in North Vietnam. The validity of Ostracolethe fruhstorfferi Simroth, 1901 is confirmed, and the unusual torus-toroid structure is discussed. A key for the determination of the helicarionoid genera of slugs and semi-slugs from North Vietnam is also provided.
