Abstract
Species are elementary units in community ecology studies. However, sample limitations obstruct
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 nonparametric 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 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.
