Pseudischyrus

Pseudischyrus is a small genus of tiny pleasing fungus beetles (family Erotylidae), containing only three described species which are apparently endemic to the USA. Little-known, this genus might just barely range into extreme northeastern Mexico, but probably they do not even reach the lower Rio Grande.

Genus Pseudischyrus is placed in subfamily Tritominae, or – in taxonomic arrangements that prefer a more comprehensive subfamily Erotylinae – in tribe Tritomini of the Erotylinae. It is considered closely related to the highly diverse Tritoma, and may even be embedded therein, making it important for any attempt to review the internal relationships of Tritoma.

Species of Pseudischyrus can only be reliably distinguished by anatomical details – the shape of the prosternum, and some features of their genitalia &ndash'; and seem to form a cryptic species complex.
