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 cimi sp. nov. and T. forceps sp. nov. from Nakhonsrithammarat Province, T. culter sp. nov., T. planispina sp. nov., T. undulatus sp. nov. and T. ursus sp. nov. from Krabi Province, T. mesocristatus sp. nov. from Songkhla Province, T. navychula sp. nov. from Phang-Nga Province and T. sutchariti sp. nov. from Phetchaburi Province.
The Indochinese to southern Chinese millipede genus Tylopus currently comprises 62 species, including eight new ones: T. flavolineatus sp. nov., T. hongkhraiensis sp. nov. from central and northern Thailand, respectively, T. moniliformis sp. nov., T. retusus sp. nov., T. acuminatus sp. nov., T. dorsalis sp. nov., T. thunghaihin sp. nov., all from Laos, and T. punctus sp. nov. from northern Myanmar. A new record of T. baenzigeri Golovatch & Enghoff, 1993, from northern Thailand is given. All these species are richly illustrated, and a modified key to all known species of the genus is also provided.
Two new species of Tetrastigma from Thailand, T. calcicola Kochaiph. & Trias-Blasi sp. nov. and T. jaichagunii C.L.Li ex Kochaiph. & Trias-Blasi sp. nov. are described and illustrated. Tetrastigma calcicola sp. nov. is a slender climber restricted to the open areas on limestone mountains at high elevation in the northern part of Thailand. The other species, T. jaichagunii sp. nov., is similar to T. harmandii Planch., but differs from it by having more densely verrucose young branches, broader leaflets, 4-lobed thick discs, bigger globose berries and oblongoid seeds. This species occurs along streams or in forest margins in evergreen forest and it is widely distributed in several parts of Thailand.
