title: Revision of the Neotropical genus Carvalhoiella De Carlo (Heteroptera: Nepomorpha: Naucoridae).
abstract: The genus Carvalhoiella De Carlo, 1963 includes saucer bugs (Heteroptera: Naucoridae) that live predominantly on the vertical rocks next to falls and cascades of waterfalls. Thus far, it has been recorded only in South America and includes three described species. In the present paper, based on type specimens and additional material, we present detailed distributions and diagnostic information of the three described species of Carvalhoiella and the descriptions of two new species from central-western Brazil: C. acuminata sp. nov. and C. helenae sp. nov. An illustrated taxonomic key also is presented.
