Review of the genus Tylopus Jeekel, 1968, with descriptions of five new species from Thailand (Diplopoda, Polydesmida, Paradoxosomatidae)

Abstract

The genus Tylopus currently contains 41 species, all keyed and mapped, including five new from northern Thailand: Tylopus bispinosus sp. n., Tylopus grandis sp. n., Tylopus extremus sp. n., Tylopus veliger sp. n. and Tylopus parajeekeli sp. n. Species of Tylopus are predominantly forest-dwellers, especially in montane habitats where up to 9–10 species can coexist per faunule. We expect many more congeners to be discovered in future, in particular from poorly or relatively poorly prospected regions such as Laos (only two species recorded), Cambodia (no species yet), Vietnam (a few species), Myanmar (a few species) and southern China (one species only). Because the genus is so species-rich and as yet so poorly sampled, a phylogenetic analysis of Tylopus would be premature.

“…Tylopus Jeekel, 1968, has long been recognized as one of the largest and widespread millipede oriental genera in the entire family Paradoxosomatidae (Likhitrakarn et al 2010). this genus has been reviewed and rediagnosed several times, chiefly in the context of adding new species (Jeekel 1965(Jeekel , 1968Golovatch & Enghoff 1993;Likhitrakarn et al 2010).…”
