Survey of the semiaquatic bugs (Hemiptera: Heteroptera: Gerromorpha) from Alagoas and Sergipe, Northeast Brazil

Abstract

A survey of the semiaquatic bugs (Hemiptera: Heteroptera: Gerromorpha) from Alagoas and Sergipe, Northeast Brazil, is presented. Specimens have been obtained mainly during three expeditions carried out in 2018 and 2019. Individuals of 40 species, representing the following 18 genera and five families have been recorded: Brachymetra Mayr, 1865, Cylindrostethus Mayr, 1865, Limnogonus Stål, 1868, Neogerris Matsumura, 1913, Tachygerris Drake, 1957, Rheumatobates Bergroth, 1892, Halobatopsis Bianchi, 1896, Ovatametra Kenaga, 1942 (Gerridae); Lipogomphus Berg, 1879, Merragata White, 1877 (Hebridae); Hydrometra Latreille, 1797 (Hydrometridae); Mesovelia Mulsant & Rey, 1852 (Mesoveliidae); Husseyella Herring, 1955, Microvelia Westwood, 1834, Rhagovelia Mayr, 1865, Paravelia Breddin, 1898, Platyvelia Polhemus & Polhemus, 1993 and Stridulivelia Hungerford, 1929 (Veliidae). Alagoas and Sergipe have 35 and 31 new records, respectively. Rheumatobates trinitatis (China, 1943) and Rhagovelia plumbea Uhler, 1894 are recorded for the first time from Brazil.

New species and new records of semiaquatic bugs (Arthropoda, Insecta, Hemiptera, Heteroptera, Gerromorpha) from French Guiana

“…Distribution. Guadeloupe (Nieser 1970), Trinidad & Tobago (China 1943, Suriname (Nieser 1970), French Guiana (this work), Brazil (Rodrigues et al 2021b). (Kenaga 1942), Bolivia (Floriano et al 2017a), Argentina (Mazzucconi et al 2022).…”

Dipsas indica (Laurenti, 1768) (Serpentes, Colubridae, Dipsandinae): additional country record, list of voucher specimens, and discussion on distribution in Bolivia

“…Halobatopsis platensis is much more widespread than the previous species, ranging from northeastern Brazil (Rodrigues et al 2012(Rodrigues et al , 2021bMoreira et al 2016;Franco et al 2020Franco et al , 2021 westward to Peru (Floriano et al 2017), and southward to Argentina and Uruguay (Berg 1879;Ruffinelli and Pirán 1959). It is herein recorded from Ouro Preto for the first time, which narrows a gap on the southeastern region of the state.…”

Semiaquatic bugs (Hemiptera, Heteroptera, Gerromorpha) from Rio Grande do Sul, southern Brazil

“…So far, 238 species of Gerromorpha have been recorded from Brazil belonging to the families Gerridae (57 species), Hebridae (9), Hydrometridae (14), Mesoveliidae (7), and Veliidae (151) (Moreira 2021a(Moreira , 2021b(Moreira , 2021c(Moreira , 2021d. Historically, the northern and southeastern regions of the country were the best explored (Moreira et al 2011a), but this has been changing in recent years due to surveys performed by local researchers, especially in the northeastern region (e.g., Franco et al 2020Franco et al , 2021Rodrigues et al 2021).…”
