A new species and a key for the Brazilian species of the genus Heterelmis Sharp, 1882 (Coleoptera: Elmidae, Elminae)
Provedor de dados: Papéis Avulsos de Zoologia
Autores: Polizei,Thiago Tadeu Silva.
Abstract Heterelmis Sharp, 1882, comprises 22 species and subspecies with 3 species assigned to Brazil so far. Here the forth species, Heterelmis debilis sp. nov. from Brazil, is described and illustrated. The type material is deposited in the Museum of Zoology of the University of São Paulo, São Paulo, Brazil (MZSP) and Natural History Museum, London, UK (NHMUK). Additionally, an identification key with distributional data for Brazilian species is proposed.

A synopsis of the South American Hydrovatus (Coleoptera: Dytiscidae: Hydroporinae), with notes on habitat and distribution, and a key to species

Autores: Trémouilles,Edgardo R.; Michat,Mariano C.; Torres,Patricia L. M.
We revised the South American members of the genus Hydrovatus Motschulsky. Each of the three recognized species is diagnosed, with emphasis on diagnostic characters. A key summarizing the main differences is provided. To identify South American specimens of H. caraibus Sharp, they were compared with Central American specimens, including type material. Based on the material examined, H. caraibus is a species broadly distributed in Central and South America, with representatives of different areas separated by minor differences. The geographical distributions of the three species are considerably enlarged: H. crassulus Sharp and H. turbinatus Zimmermann are recorded for the first time from Paraguay, and H. caraibus is recorded for the first time from...

A preliminary study of aquatic Coleoptera in temporary ponds and the ecological variables influencing their richness and diversity
Provedor de dados: Revista de la Sociedad Entomológica Argentina
Autores: GÓMEZ LUTZ,María C.; KEHR,Arturo I.
Water beetles possess a wide variety of ecological attributes that allow them to occupy a wide range of aquatic habitats. Temporary ponds are environments that experience recurrent drought periods that may differ in duration; each pond is further characterized by a particular fauna, and by the size of the population that can be supported. The richness (S) and diversity (H') of water beetles collected in temporary ponds in Corrientes province were analyzed. Rarefaction was used to avoid estimation bias and to use comparative methodology. Pearson correlations were calculated using water temperature, depth, surface (m²), diversity (Shannon &amp;amp; Wiener) and richness. A total of 660 individuals, including 42 species, 22 genera and 7 families were recorded....
