The genus Hylomus Cook & Loomis, 1924 is
reviewed from Vietnam, with 13 recorded species. Of these, three are
described as new, H. songoku
sp. nov. from Xuan Son National Park, H.
namek sp. nov. from Cuc Phuong National Park, and H. saiyans sp. nov. from Vinh Phuc
and Ha Giang Provinces. The new species, H. songoku sp. nov., is
distinguished by gonopod solenophore with rounded lobuliform lamina
medialis, and well-developed lamina lateralis with a densely setose
area; tip of gonopod tuberculiform. H.
namek sp. nov. is separated from its congeners by its gonopod
femorite being short, parallel-sided, slightly constricted at the
middle; tip of gonopod rounded; and lastly, H. saiyans sp. nov. is diagnosable
by its gonopod femorite being long and enlarged distally, postfemoral
region short, tip bilobuled. The relationship among Hylomus species from Vietnam was
analyzed using a fragment of the 16S rRNA mitochondrial gene. The
analysis supports the monophyly of the genus Hylomus. It is recommended that
more Hylomus species be added
in the analysis to better clarify the phylogenetic relationships in the
Key words: Dragon millipedes, Diplopoda, New
species, Phylogeny, Vietnam.
