水生臭虫科Naucoridae(半翅目:异翅目:Nepomorpha)目前在巴西有68种。尽管家庭的多样性一直是最近几项研究的目标,该国的大片地区仍未开发,一些已存放在昆虫学收藏中的物种正在等待正式描述。为了填补这些知识空白,在2018年至2023年之间,在巴西东部的六个州进行了一系列探险:阿拉戈斯,巴伊亚,Ceará,圣埃斯皮里托,伯南布哥州,还有Sergipe.实地调查的目标是保护区,但周边地区也进行了探索。获得的材料,除了先前保存在国家昆虫学收藏中的标本外,揭示了南澳大利亚的存在,桑托斯和莫雷拉,这里描述的一个新物种,以及属于CarvalhoiellaDeCarlo属的其他11种和两个亚种的新记录,1963年,林诺科里斯·斯特尔,1876年,MaculambrysusReynoso-Velasco和Sites2021年,以及PelocorisStál,1876.
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.
