Dactylosternum pui sp. nov. is described from Guangxi, China. It closely related to D. dohertyi Balfour\|Browne but differs from the latter by prosternum very strongly tectiform in middle and sharp carinate medially and with a distinct anteromedian tooth and different aedeagus. The new species can be separable from D. densepunctatum d′Orchymont by tectiform and carinate prosternum and with tooth anteromedially, median femora with dense and short pubescence.
