One of the most abundant and rich families of aquatic Coleoptera is Hydrophilidae, with approximately 2,840 described species distributed in 174 genera and 5 subfamilies, distributed worldwide.

The samples were performed in June and August of 2015 in 26 lakes of the Roraima savanna. It were collected 1863 adults belongs to five subfamilies, five tribes, ten genera and 35 species, of which seven are new to science: Berosus apiciflatus sp. nov.; Berosus atratus sp. nov.; Berosus cordatus sp. nov.; Berosus aurifer sp. nov.; Berosus clarksoni sp. nov.; Crenitulus savanna sp. nov. and Derallus roraimenses sp. nov.

An identification key is provided for the genera and species registered for the study area, based on both, external morphological characters and on characteristics of the male genitalia. In addition, diagnoses and comments were included, as well as maps with geographical records for each species. Os besouros aquáticos constituem o principal grupo de artrópodes de água doce, tanto pelo número de espécies, como por sua importância, participando das cadeias e redes tróficas aquáticas. Uma das famílias mais abundantes e ricas de coleópteros aquáticos é Hydrophilidae, com aproximadamente 2.840 espécies descritas, distribuídas em 174 gêneros e 5 subfamílias, distribuidas mundialmente. Apesar da grande diversidade e riqueza do grupo, seu conhecimento ainda é bastante restrito, principalmente pela carência de especialistas e disponibilidade de ferramentas que visem a identificação das espécies. O presente estudo teve como objetivo caracterizar os gêneros de Hydrophilidae encontrados na área de estudo, descrever as novas espécies, redescrever espécies que apresentam descrição sucinta, elaborar chave de identificação para os gêneros e as espécies e fornecer informações sobre a distribuição geográfica das espécies. As coletas dos exemplares foram realizadas nos meses de junho e agosto de 2015 em 26 lagos da savana de Roraima. Foram coletados 1863 exemplares adultos, pertencentes a cinco subfamílias, cinco tribos, dez gêneros e 35 espécies, das quais sete são novas para a ciência: Berosus apiciflatus sp. nov.; Berosus atratus sp. nov.; Berosus cordatus sp. nov.; Berosus aurifer sp. nov.; Berosus clarksoni sp. nov.; Crenitulus savana sp. nov. e Derallus roraimenses sp. nov. Das espécies encontradas no presente estudo nove são registradas pela primeira vez para o Brasil (Berosus castaneus Oliva & Short, 2012; Berosus llanensis Oliva & Short, 2012; Berosus megaphallus Oliva & Short, 2012; Berosus olivae Queney, 2006; Berosus repertus Oliva & Short, 2012; Paracymus sedatus Wooldridge, 1973; Hydrophilus simulator Bedel, 1891; Tropisternus apicipalpis Fabricius, 1775; Tropisternus laevis Sturm, 1826) e todas as espécies são primeiro registro para estado de Roraima. É fornecida chave de identificação dicotômica para os gêneros e espécies registradas para a área de estudo, baseadas tanto em caracteres morfológicos externos como nas características da genitália masculina. Foram incluídos diagnoses e comentários, além de mapas com registros geográficos para cada espécie. 2020-02-17T20:22:03Z 2020-02-17T20:22:03Z 2017-03-28 Dissertação https://repositorio.inpa.gov.br/handle/1/12521 http://lattes.cnpq.br/8306312448982945 por Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Instituto Nacional de Pesquisas da Amazônia - INPA Entomologia |

| description |
Water beetles are the main group of freshwater arthropods, both, by the number of species as
by its importance, since they participate in the aquatic chains and food webs. One of the most
abundant and rich families of aquatic Coleoptera is Hydrophilidae, with approximately 2,840
described species distributed in 174 genera and 5 subfamilies, distributed worldwide. Despite
the great diversity and richness of the group, their knowledge is still limited, mainly due to the
lack of specialists and the availability of tools that aim at the identification of the species. The
present study aimed to characterize the genera of Hydrophilidae found in the study area, to
describe the new species, to redescribe species with description short and brief, to make
identification key for genera and species and to provide information on the geographic
distribution of the species. The samples were performed in June and August of 2015 in 26
lakes of the Roraima savanna. It were collected 1863 adults belongs to five subfamilies, five
tribes, ten genera and 35 species, of which seven are new to science: Berosus apiciflatus sp.
nov.; Berosus atratus sp. nov.; Berosus cordatus sp. nov.; Berosus aurifer sp. nov.; Berosus
clarksoni sp. nov.; Crenitulus savanna sp. nov. and Derallus roraimenses sp. nov. Of the
species found in the present study nine are new records for Brazil (Berosus castaneus Oliva &
Short, 2012; Berosus llanensis Oliva & Short, 2012; Berosus megaphallus Oliva & Short,
2012; Berosus olivae Queney, 2006; Berosus repertus Oliva & Short, 2012; Paracymus
sedatus Wooldridge, 1973; Hydrophilus simulator Bedel, 1891; Tropisternus apicipalpis
Fabricius, 1775; Tropisternus laevis Sturm, 1826) and all species are new records for Roraima
State. An identification key is provided for the genera and species registered for the study
area, based on both, external morphological characters and on characteristics of the male
genitalia. In addition, diagnoses and comments were included, as well as maps with
geographical records for each species. |
