Abstract. The braziliansavannah, called Cerrado, has the richest flora among the world’s savannahs, and the State of Goiás comprises part of this biome. We present here a checklist for Goiás based on literature and specimens collected, with 18 species of Notonectidae, including new distribution records of Martarega membranacea White, 1879, and first records of Buenoa konta Nieser & Pelli, 1994; Buenoa pseudomutabilis Barbosa, Ribeiro & Nessimian, 2010; Buenoa tarsalis Truxal, 1953; Martarega bentoi Truxal, 1949 and Martarega brasiliensis Truxal, 1949 in the State. This checklist highlights a gap in the knowledge of Notonectidae and a great necessity of works with diversity of backswimmers in Goiás.Lista de espécies e registros novos de Notonectidae (Hemiptera: Heteroptera: Nepomorpha) do Estado de Goiás, BrasilResumo. A savanna brasileira, chamada de Cerrado, possui a maior riqueza de flora dentre as savannas mundiais, e o Estado de Goiás encontra-se dentro dos limites deste bioma.

Esta lista destaca uma lacuna no conhecimento de Notonectidae e a grande necessidade de desenvolvimento de artigos com foco na diversidade de Notonectidae em Goiás.

“…Enitharoides Brooks (Notonectini), exclusively Neotropical, was created as a subgenus of Enithares Spinola to include its Neotropical species, being posteriorly raised to genus by Štys and Říha ( 1975 ). Notonecta (Notonectini) is the only cosmopolitan genus of Notonectidae, with about 40 Neotropical species (Hungerford 1933 ;Mazzucconi et al 2009 ;Barbosa and Nessimian 2013 ). The genus was reviewed by Hungerford ( 1933 ), and few species were described since then.…”

The True Water Bugs (Nepomorpha)

True Bugs (Heteroptera) of the Neotropics

The infraorder Nepomorpha is one of the most specialized groups of heteropterans, with most of its species spending the entire life cycle within the water. True water bugs include ten families, 52 genera, and approximately 730 species in the Neotropical region, which shelters about 30 % of the global diversity of the group. Despite this fact, little is known about their biology, ecology, and geographical distribution in the Neotropics. Several genera need to be revised and many species remain with outdated descriptions. The systematics of the infraorder, although has received little attention in recent years, remains with various unresolved questions, and no phylogenetic study was conducted for any endemic group of this region.

Resurrecting the genus Enitharoides Brooks, 1953 (Heteroptera: Nepomorpha: Notonectidae): description of three new species and redescription of Enitharoides brasiliensis (Spinola, 1837), comb. nov.

The subgenus Enitharoides Brooks, 1953 was erected to include two species of Enithares from South America with asymmetry in the male genital capsule: Enithares brasiliensis Spinola, 1837 and E. duidaensis Brooks, 1953. Enitharoides was elevated to genus in 1975, but neither it nor its species have been redescribed. Here the genus is redescribed, fixing the identity of the type-species as Enitharoides duidaensis, comb. nov. Members of this genus can be recognized by the triangular labrum, pronotum with anterolateral margins foveate, punctate scutellum, fore and middle legs with three tarsomeres, middle femur with an anteapical pointed protuberance, and an asymmetrical genital capsule. We transfer Enithares brasiliensis to Enitharoides; thus, Enitharoides brasiliensis is a new combination. A redescription of E. brasiliensis is given and three new species of Enitharoides are described from Brazil: E. lucasduquei Barbosa, Ribeiro & Nessimian, sp. nov. from Rio de Janeiro, E. tricomerus Barbosa, Ribeiro & Nessimian, sp. nov. from Espírito Santo and Minas Gerais, and E. lanemeloi Barbosa, Ribeiro & Nessimian, sp. nov. from Minas Gerais. A taxonomic key to the males of species of Enitharoides and a key to nymphs of the genera of Notonectidae occurring in Brazil are provided.
