ABSTRACT
We analysed the diversity of Cerambycidae in three phytophysiognomies, one of Cerrado (cerradão) and two of Atlantic Forest (freshwater swamp forest and semideciduous seasonal forest) within the Municipal Botanical Garden of Bauru (central São Paulo State, Brazil), a relevant preservation area. Ceramybycidae, one of the most diverse beetle families, are important bioindicators due to their intimate relationship with their host plants. They have great ecological importance as one of the major groups of decomposers. Despite having a crucial role in forest ecosystems, detailed faunistic studies of the family are scarce. Sampling of adult Cerambycidae was conducted with malaise traps from October 2019 to September 2020. In total, we collected 69 species, mostly belonging to Cerambycinae and Lamiinae. Isomerida vittata (Pascoe, 1858) was the most abundant species. Species accumulation curves show sufficient sampling effort. We found higher abundances during the spring–summer period, indicating a seasonal distribution pattern. A comparison of species composition among the three areas showed that cerradão and semideciduous seasonal forest are more similar; a lower similarity was calculated between freshwater swamp forest and semideciduous seasonal forest. Diversity profiles show that the cerradão is the most diverse area and freshwater swamp forests have the highest evenness. Our study is one of the few survey studies of Cerambycidae in large remnant areas of the Cerrado and Atlantic Forest and provides primary data on this taxon which may help to develop future conservation policies.
