The neotropical saucer bug genus Maculambrysus Reynoso & Sites is currently represented by five species from Tabasco, Mxico to Par, Brazil. Presented here is the description of a sixth species, Maculambrysus gallicei n.sp., which was collected from rootmats and leafpacks in an aguaje palm swamp in southeastern Peru. It can be distinguished from most congeners by the concolorous dark-brown hemelytra and the mottled orange-brown pronotum, as well as characteristics of the male accessory genitalic process of tergum VI, and female subgenital plate and laterosternites VI. Other aquatic Heteroptera co-occurring with this new species are given.

Although recent studies have been published on Ambrysinae (Naucoridae) from the Neotropical region, few efforts have been made to improve the taxonomic knowledge of this subfamily in Brazil. Two genera of Ambrysinae containing the greatest number of species in South America were recently established to accommodate species previously classified as Ambrysus Stål: Australambrysus Reynoso & Sites and Maculambrysus Reynoso & Sites. The subgeneric classification of Ambrysus has also changed, including the elevation of Melloiella De Carlo back to full generic status.

The aquatic bug family Naucoridae (Hemiptera: Heteroptera: Nepomorpha) is currently represented in Brazil by 68 species. Although the diversity of the family has been the target of several recent studies, large areas of the country are still unexplored and several species that have been deposited in entomological collections are waiting for a formal description. Aiming to fill these knowledge gaps, a series of expeditions were carried out in six states of eastern Brazil between 2018 and 2023: Alagoas, Bahia, Ceará, Espírito Santo, Pernambuco, and Sergipe.
