Alguns aspectos sobre morfologia e ciclo de vida de Limnogonus recurvus (Hemiptera: Gerridae)

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.

Eighteen species from seven genera are recorded from the Amazon River floodplain, Brazil. An identification key, diagnoses, drawings, and taxonomic and biological notes are given for these species. The main features used in the identification key and diagnoses are: body and leg segments proportions, coloration patterns, presence and distribution of setae, and modifications of the apical abdominal segments and external genitalia of the male. Based on material collected in the floodplain streams and lakes, Cylindrostethus bassleri Drake, 1952 is recorded for the first time from Brazil, and new municipality records are presented for Brachymetra lata Shaw, 1933, B. shawi Hungerford & Matsuda, 1957, C. erythropus (Herrich-Schäffer, 1850), C. linearis (Erichson, 1848), C. Palmaris Drake & Harris, 1934, C. regulus (White, 1879), Neogerris lotus (White, 1879), N. lubricus (White, 1879), N. visendus (Drake & Harris, 1934), Ovatametra obese Kenaga, 1942, Rheumatobates crassifemur esakii Schroeder, 1931, R. klagei Schroeder, 1931, and Trepobates taylori (Kirkaldy, 1899). Additional new records from the Brazilian Amazon are presented for B. lata and O. obesa

Gerromorpha (Hemiptera: Heteroptera) comprises more than 2100 species of semiaquatic bugs, most of which have the ability to walk on the surface of the water. So far, 238 species have been recorded from Brazil, but several portions of the country remain poorly explored. The Metropolitan Region of Santarém (MRS), Pará State, Brazil, lacks faunistic and taxonomic studies concerning this group and the local fauna is under threat due to human actions. Aiming to fill gaps concerning the diversity and distribution of Gerromorpha in the Amazon, a survey of the semi-aquatic bugs from the MRS is presented. Collections were made in 33 aquatic ecosystems in the different phytophysiognomies within this area from July 2019 to October 2020. As a result, a checklist with 44 species recorded from the three municipalities of the MRS is presented. Furthermore, three new species of the genus Microvelia Westwood, 1834 (M. belterrensis sp. nov., M. hamadae sp. nov. and M. sousorum sp. nov.) are described, two species are recorded for the first time from Brazil (Microvelia aschnakiranae Makhan, 2014 and Rhagovelia graziae Galindo-Malagón, Morales & Moreira, 2021), two from Pará State (Microvelia longipes Uhler, 1894 and Paravelia dilatata Polhemus & Polhemus, 1984) and 15 from the MRS (Brachymetra lata Shaw, 1933, B. shawi Hungerford & Matsuda, 1957, Tachygerris adamsoni (Drake, 1942), Microvelia pulchella Westwood, 1834, Rhagovelia brunae Magalhães & Moreira, 2016, R. evidis Bacon, 1948, R. jubata Bacon, 1948, Callivelia conata (Hungerford, 1929), Oiovelia cunucunumana Drake & Maldonado-Capriles, 1952, Paravelia bullialata Polhemus & Polhemus, 1984, Stridulivelia alia (Drake, 1957), S. stridulata (Hungerford, 1929), S. strigosa (Hungerford, 1929), S. tersa (Drake & Harris, 1941) and S. transversa (Hungerford, 1929)).
