We studied molecular and morphological diversity of Platerodrilini from China. Oriental and Palearctic Platerodrilus were included in a phylogenetic analysis and major lineages are identified using molecular data and morphology. We reinstate Duliticola Mjöberg, 1925 from the synonymy of Platerodrilus Pic, 1921 as a subgenus in Platerodrilus s. 1. Additionally, we propose a new subgenus Zhelongia subgen...

Both genera were previously unknown in Iran. The occurrence of Ovalocephalus represents the earliest sign of westward taxon migration from China towards higher...
