Species are elementary units in community ecology studies.However, sample limitations obstruct vegas golden knights background the elaboration of accurate faunistic inventories, especially in biodiversity hotspots, such as tropical forests.In this way, the objective of this research was to describe the richness, using different non-parametric estimators of richness, in the family Cerambycidade, a group of hyperdiverse insects in the Atlantic Forest.

Five hundred and eighty-one specimens belonging to 145 species and 3 subfamilies were collected.Among the species sampled, 46.2% were considered singletons, 13.

8% doubletons, 48.95% unicates, 15.15% duplicates and 90.

3% ecologically rare.The species accumulation curves did not stabilize, which was already expected considering that more species and individuals were sampled in the last months of collection.The estimated richness presented values much higher than the observed richness.

This was a reflect of the high proportion of ecologically rare species present in the sample.This work showed that read more faunistic inventories of hyperdiverse groups, with only one year of collection and a single sampling methodology may underestimate the species richness of a region.Thus, larger time series associated with different collection methods are essential for a more accurate survey of biodiversity in the Atlantic Forest.
