The taxonomy of the genus Hansreia Halffter & Martínez is reviewed. The genus consists of six species, including three new species: H. peugeoti sp. nov., H. grossii sp. nov., H. krinskii sp. nov. Lectotypes are designated for Hansreia affinis (Fabricius 1801), H. oxygona (Perty 1830) [here considered a valid species] and H. coriacea (Schmidt 1922). The species status of H. coriacea is recognized. A detailed literature review, synonymies, description, illustration of key morphological characters…

TLDR
It is shown that Streblopus is a relict genus composed of two currently living species of widely disjunct distribution and an African origin is proposed based on its close phylogenetic relationship with a group of Old World taxa ‒ particularly Circellium Latreille, 1825 and Scarabaeini.
