Diversidade de Cerambycidae no Piauí: um estudo da literatura científica

Abstract

The state of Piauí, located between major biomes such as the Amazon Forest, Cerrado, and Caatinga, exhibits a rich diversity of ecosystems and vegetation formations. However, the Cerambycidae fauna (longhorn beetles) in the region remains poorly studied. In this context, we executed a systematic bibliographical search in Google Scholar platform, using the keywords “Coleoptera”, “Cerambycidae” and “Piauí”, restricting results to papers published from the year 2005 to 2024. This methodology made possibe to identify publications who directly approached the Coleoptera order, Cerambycidae family and the State of Piauí. This research compiled existing literature data and identified a total of 145 species in the state, with Cerambycinae (106 species) and Lamiinae (43 species) as the most represented subfamilies, while Prioninae had only three recorded species. Most occurrences are associated with the Caatinga biome, followed by the Cerrado, although the broad scope of some studies complicates precise biome attribution for each record. This distribution pattern mirrors findings from other Brazilian regions such as the northeastern semi-arid, Amazon, and Cerrado, where Cerambycinae and Lamiinae also predominate, suggesting high adaptability of these subfamilies across diverse environments from humid to dry. Beyond their diversity, Cerambycidae play essential ecological roles, contributing to organic matter decomposition, nutrient cycling, and, in some cases, pollination and seed dispersal. Their close relationship with host plants and sensitivity to environmental changes make them effective bioindicators of ecosystem quality. Despite this importance, research on Cerambycidae in Piauí is limited and geographically concentrated, highlighting the need for further studies in underexplored areas.
