Two new pill millipedes (Diplopoda: Glomerida: Glomeridae) from high mountains of Vietnam

ABSTRACT

Two new pill millipede species, namely Hyleoglomeris hoanglien sp. nov. and H. fanxipan sp. nov., are described from high elevations (approximately 2,800–2,900 m) of the Hoang Lien National Park, northern Vietnam. A new species, H. hoanglien sp. nov. is clearly distinguished by the telopods being short, stout and incrassate, femora strongly condensed, tibia without modifications, syncoxital lobe bifid trapeziform, and syncoxital horns with an apical seta and a spine. Hyleoglomeris fanxipan sp. nov., is diagnosed by the telopods being long and robust, tibia without modifications, syncoxital lobe roundly trapeziform, and syncoxital horns truncated at tip. COI-based DNA barcodes of the two species are also provided for the first time in the genus Hyleoglomeris. The K2P genetic distance between the two new species is 0.148. In addition, an identification key to the Vietnamese Hyleoglomeris species is also provided.
