Review of Dragon Millipedes (Diplopoda Polydesmida Paradoxosomatidae) inthe Fauna of Vietnam with Descriptions of Three New Species

摘要

The genus Cook & Loomis, 1924 is reviewed from Vietnam, with13 recorded species. Of these, three are described as new, sp.nov. from Xuan Son National Park, sp. nov. from Cuc PhuongNational Park, and sp. nov. from Vinh Phuc and Ha GiangProvinces. The new species, sp. nov., is distinguished bygonopod solenophore with rounded lobuliform lamina medialis, and well-developed laminalateralis with a densely setose area; tip of gonopod tuberculiform. 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, sp. nov. is diagnosable by its gonopod femorite being longand enlarged distally, postfemoral region short, tip bilobuled. The relationship among species from Vietnam was analyzed using a fragment of the 16SrRNA mitochondrial gene. The analysis supports the monophyly of the genus . It is recommended that more speciesbe added in the analysis to better clarify the phylogenetic relationships in thegenus.
