Amarodytes régimbart, 1900 (coleoptera: dytiscidae) da Serra do Espinhaço, Brasil: taxonomia e distribuição

Abstract

Amarodytes Régimbart, 1900 (Hydroporinae: Bidessini) is a predaceous diving beetles genus, restricted to Neotropical Region, which currently has 11 valid species. This project aimed to perform a taxonomic study of the Amarodytes of lentic water habitats from Serra do Espinhaço, Brazil. In this work eight species were studied, three of them are known to science and five are new. Amarodytes duponti (Aubé, 1838), A. guidi Guignot, 1957 and A. segrix Guignot, 1950 were herein redescribed and their known distribution was expanded. Five new species were described: A. bifidus sp. nov., A. ferrarius sp. nov., A. ferrodoidensis sp. nov., A. malheirensis sp. nov. e A. parallelus sp. nov. Diagnoses, geographical distribution maps and illustrations were provided for all species in this study. Due to this work, the genus now consists of 16 valid species and its geographic distribution has been expanded thanks to new records of A. duponti, A. guidi and A. segrix and new species. Therefore, with the analyzes carried out in this work, knowledge about the group becomes accessible to the scientific community, which will facilitate the carrying out of future work, mainly for a taxonomic review.
