Revision of Limnocoris Stål (Heteroptera: Naucoridae) of eastern South America

The genus Limnocoris is the only genus in the New World subfamily Limnocorinae (Naucoridae) and is predominantly neotropical in distribution. Presented here is the fourth and final contribution in a series to revise the genus; the species of eastern South America are revised, including the descriptions of three new species from Brazil: L. diamantinensis sp. nov., L. hirsutus sp. nov., and L. valimi sp. nov. Also, Limnocoris montandoni La Rivers stat. restit. is resurrected from synonymy with L.
