a revision of the thyropygus allevatus group. part v: nine new species of the extended opinatus subgroup, based on morphological and dna sequence data (diplopoda: spirostreptida: harpagophoridae)
The Thyropygus opinatus subgroup (Diplopoda: Harpagophoridae) of the T. allevatus group in Thailand is revised. Based on a phylogenetic analysis of mtDNA sequence data, it is merged with the T. bifurcus subgroup to form an extended T.opinatus subgroup. Nine new species are described: Thyropygus cimisp. nov. and T. forcepssp. nov. from Nakhonsrithammarat Province, T. cultersp. nov., T. planispina sp. nov., T. undulatussp. nov. and T. ursussp. nov.from Krabi Province, T. mesocristatussp. nov.from Songkhla Province, T. navychulasp. nov.from Phang-Nga Provinceand T. sutchariti sp. nov.from Phetchaburi Province.
