Taxonomia e análise filogenética de Hypolampsis Clark, 1860 (Coleoptera: Chrysomelidae: Galerucinae: Alticini: Monoplatina)

Abstract

Coleoptera compose the largest Order, standing out for its great taxonomic and functional diversity. Within this diversity the family Chrysomelidae take the third position, whose representatives are predominantly phytophagous. They are of ecological and economic importance, with some species causing damage to important crops, while others are used efficiently for weed control. Currently composed of 12 subfamilies, Galerucinae stands out as the most diverse, and within it Alticini is the tribe with the highest species richness. In Brazil there are around 1.407 species in 142 genera, thus being a very diverse group. The Alticini are known as "flea beetles" because of the usually well-developed metafemur and that internally contains a sclerite - the metaphemoral spring, which contributes to its ability to jump. Despite having a great diversity, economic and ecological importance, knowledge about this tribe is still scarce mainly in the Neotropical Region in several aspects such as taxonomy, phylogeny, ecology and natural history. Thus, considering the lack of taxonomic and phylogenetic studies with Neotropical distribution alticinis, mainly those from South America, the present work was developed. Thus, we carried out a taxonomic study of the species of Hypolampsis Clark, 1860 (Alticini: Monoplatina), where 27 species were redescribed, three of them revalidated, three new species were described and a new synonym proposed. In addition, a hypothesis of relationships between Hypolampsis species and their monophilia was tested, which proved to be polyphyletic, requiring further studies to better understand the relationships between their species and their close genera.
