Abstract

Material of the giant pill-millipede genus Zephronia Gray, 1832 recently collected from Thailand contains three new species: Zephroniaenghoffi sp. nov., Zephroniagolovatchi sp. nov., and Zephroniapanhai sp. nov. The first Zephronia species recorded for Thailand, Z.siamensis Hirst, 1907, is also redescribed based on new specimens collected both from the type locality in Chonburi Province and from neighboring areas. Morphological characters of all new species, Z.phrain Likhitrakarn & Golovatch, 2021, and Z.siamensis are illustrated, and a distribution map of the confirmed Zephronia species occurring in Thailand is also provided.
