AI Article Synopsis
- The terrestrial semislug genus, which belongs to the Helicarionidae family, includes nine species found in Thailand and Myanmar, with two species based solely on shell characteristics.
- The taxonomy of these species is discussed using comparative morphology, leading to revised descriptions for four existing species, and the reclassification of another species into this genus.
- Two new species, Pholyotha & Panha, sp. nov., are introduced, and unique shell and genital features are highlighted as distinguishing factors, with only one species lacking a dart apparatus.
Article Abstract
is a terrestrial semislug genus in the family Helicarionidae and currently comprises nine species recorded from Thailand and Myanmar. Two species, and , have been described based only on shell information, while the taxonomy of the remaining seven species is comprehensively treated herein using comparative morphology. Revised species descriptions are given for , , , and ; (previously placed in the ) is moved to this genus; and two species, Pholyotha & Panha, sp. nov. and Pholyotha & Panha, sp. nov., are described as new to science. Based on our findings, the combination of shell characters including shape, size, aperture, and umbilicus; the number of mantle extensions; and the genitalia, especially the penis, epiphallus, and dart apparatus, can be used to distinguish these nine species. Among these nine recognised species, only Pholyotha & Panha, sp. nov. has no dart apparatus.
