Delopleurus mencli sp. nov. is described from Socotra Island, Yemen, and its diagnostic characters including external male genitalia are illustrated. The new species can be distinguished from all nine previously known species mainly by the sculpture of the pygidium of both males and females.
Discovery of this new species on Socotra Island links disjunctive Afro-Oriental distribution of the genus Delopleurus Erichson, 1847, previously reported only from the Sub-Saharan Africa and the Indian subcontinent.
