RESUMEN
ABSTRACT The genus Curicta Stål comprises aquatic insects commonly known as water scorpions and typically occurs in habitats associated with marginal mud. It is exclusively distributed in the New World, with 17 species recorded in the Neotropical Region, including 12 in Brazil. In the state of Maranhão, only one species, Curicta montei De Carlo, has been documented to date. Thus, this study aims to explore the diversity of Curicta in the state of Maranhão. A total of 124 specimens were collected, representing three species: Curicta granulosa De Carlo, C. johnpolhemi Keffer, and C. montei. Notably, C. johnpolhemi and C. granulosa are reported here as new distribution records for the state of Maranhão. Previously described based solely on a single female, our investigation of C. johnpolhemi enabled the description of the male, providing additional taxonomic insights for the species. Photographs of one specimen from each species are provided and diagnostic features are illustrated.
RESUMEN
Rhagovelia Mayr, 1865 (Hemiptera: Heteroptera: Veliidae) is a species-rich and widespread genus of semiaquatic bugs, found both in freshwater and coastal marine environments. Despite the considerable number of species recorded from Brazil, the northern and northeastern regions of the country remain poorly explored. We present here the description of a new species of the angustipes complex, Rhagovelia leilae Paiva, Rodrigues & Moreira, sp. nov., and new records for the following species: R. brunae Magalhães & Moreira, 2016; R. evidis Bacon, 1948; R. hambletoni Drake & Harris, 1933; R. humboldti Polhemus, 1997; R. tenuipes Champion, 1898; and R. whitei (Breddin, 1898). These include the first records of species of Rhagovelia from the states of Pernambuco and Tocantins, and also increase the number of known species from the states of Alagoas, Bahia, and Maranhão to six, five and six, respectively.
