A New Species of Spelaeometra Polhemus & Ferreira, 2018 (Hemiptera: Heteroptera: Hydrometridae) from a Hotspot of Troglobites in Brazil, Serra do Ramalho Karst Area.

Spelaeometra Polhemus & Ferreira, 2018 (Hemiptera: Heteroptera: Hydrometridae) is a monotypic and troglobitic genus, recently described based on material collected in the state of Minas Gerais, Brazil. From specimens collected in the Gruna do Enfurnado Cave in the Serra do Ramalho karst area, municipality of Coribe, state of Bahia, Brazil, we describe Spelaeometra hypogea Cordeiro & Moreira, sp. nov. and compare it with Spelaeometra gruta Polhemus & Ferreira, 2018. The new species is diagnosed by the general body color being pale-yellow to light-brown; antennal segments I and II being subequal in length; the reduced gular lobe, not covering any labial segment; the male proctiger without apical projections; and the male paramere with convex dorsal margin after the curvature, with a narrow hook-like apex.

New distributional data on aquatic and semiaquatic bugs (Hemiptera: Heteroptera: Gerromorpha & Nepomorpha) from South America.

BACKGROUND: Water bugs in general play an important role in freshwater ecosystems, and knowledge about them is essential for the study of water biology and the proper management of aquatic habitats. The Neotropical fauna is relatively well known, but the existence of large under-collected areas makes taxonomic and faunistic studies concerning the aquatic and semiaquatic bugs from tropical America urgent. NEW INFORMATION: Distributional information is presented for thirty-eight species of Gerromorpha and five Nepomorpha, including first records from the Brazilian states of Bahia (Mesoveliaamoena), Ceará (Limnogonusprofugus and Rhagoveliawhitei), Espírito Santo (R.lucida), Goiás (Halobatopsisplatensis and R.zela), Mato Grosso (Rheumatobatesbonariensis), Pará (Nerthraterrestris), Paraná (H.spiniventris, Hydrometrafruhstorferi and R.janeira), Piauí (Microveliaayacuchana, M.pulchella, Neogerrislubricus and Platyveliabrachialis), Rio de Janeiro (Martaregabentoi) and São Paulo (Rheumatobatesminutusflavidus); and the Peruvian region of Madre de Dios (Rhagoveliafontanalis).
