Review of the pill millipede genus Hyperglomeris Silvestri, 1917 (Diplopoda, Glomerida, Glomeridae) with description of two new species from Laos.

The pill millipede genus Hyperglomeris Silvestri, 1917 is reported from Laos for the first time. Two new species, namely H.bicaudata Likhitrakarn, sp. nov. and H.inkhavilayi Likhitrakarn, sp. nov. , from Houaphanh and Khammouane provinces, northern Laos, are described and illustrated based on morphological characters and molecular analyses. Sequences of COI gene were used as DNA barcoding markers, and successfully supported the accurate identification of other Glomeridae species. Interspecific divergence of the COI uncorrected p-distance between these new species and other Hyperglomeris species ranged from 7.84-13.07%, while the intraspecific divergence was 0.45% in H.inkhavilayi sp. nov. and 5.3% in H.bicaudata sp. nov. The updated status of Hyperglomeris , a map of its distribution, and identification keys for all species are given.
