Nonnus niger (Brullé, 1846) (Hymenoptera: Ichneumonidae: Nesomesochorinae) in eastern Uruguay: new records and comments about phenology

Abstract

The genus Nonnus Cresson, 1874 (Hymenoptera: Ichneumonidae: Nesomesochorinae) contains 20 species distributed in the New World and so far, no species of this genus has been recorded for Uruguay. Thus, the objective of this work was to investigate the occurrence, abundance and sex ratio of Nonnus niger (Brullé, 1846) in three different phytophysiognomies in eastern Uruguay.
