A revision of dragon millipedes II: the new genus Nagaxytes gen. nov., with the description of three new species (Diplopoda, Polydesmida, Paradoxosomatidae)

The ‘acantherpestes’ group of dragon millipedes, formerly placed in the genus Desmoxytes Chamberlin, 1923, is revised and assigned to the new genus Nagaxytes Srisonchai, Enghoff & Panha gen. nov. Desmoxytes acantherpestes Golovatch & Enghoff, 1994 is the type species of the new genus and is redescribed as N. acantherpestes (Golovatch & Enghoff, 1994) gen. et comb. nov. Three new species are described from Thailand: N. erecta Srisonchai, Enghoff & Panha gen. et sp. nov. and N. gracilis Srisonchai, Enghoff & Panha gen. et sp. nov. from Kanchanaburi Province, and N. spatula Srisonchai, Enghoff & Panha gen. et sp. nov. from Tak Province. All new species are endemic to western Thailand and all are restricted to limestone habitats. Complete illustrations of external morphological characters, an identification key, and a distribution map are provided.
