DESCRIPTION OF A NEW SPECIES AND NEW RECORDS OF NAUCORIDAE (HEMIPTERA: HETEROPTERA: NEPOMORPHA) FROM EASTERN BRAZIL
Simple Summary: True bugs (Hemiptera: Heteroptera) of the infraorder Nepomorpha are known as aquatic bugs because most of them spend almost their entire life cycle submerged. Naucoridae are the third most diverse family of aquatic bugs, including eight subfamilies, 43 genera, and over 400 species. They are commonly known as saucer bugs, and occur in standing and flowing freshwater courses globally, except for Antarctica and the Pacific oceanic islands. The family is represented in Brazil by 68 species, most of which are endemic. Although the diversity of the family has been the target of several recent studies, large areas of the country are still unexplored and there are several species unknown to science. Aiming to fill these knowledge gaps, a series of expeditions were carried out in seven states of eastern Brazil between 2018 and 2023. In addition, the examination of specimens previously deposited in a national entomological collection resulted in the discovery of a new species and new geographic distribution records for 11 other species and two subspecies of the family.

Abstract
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. The fieldwork targeted protected areas, but surrounding regions were also explored. The material obtained, in addition to specimens previously deposited in a national entomological collection, revealed the existence of Australambrysus margaritifer Jordão, Santos and Moreira, a new species herein described, and new records for other 11 species and two subspecies belonging to the genera Carvalhoiella De Carlo, 1963, Limnocoris Stål, 1876, Maculambrysus Reynoso-Velasco and Sites 2021, and Pelocoris Stål, 1876.
