Monomachus (Hymenoptera, Monomachidae) del bosque lluvioso Atlántico del Estado de São Paulo, Brasil

Abstract

A survey of Monomachus (Hymenoptera, Monomachidae) was carried out with five Malaise traps/area in five areas of Atlantic Rainforest in São Paulo State, Brazil. The sampling effort in all localities amounted to 9,900 traps-day. Data were obtained from a total of 304 exemplars of Monomachus: 66 females and 238 males. The highest occurrence of Monomachus was observed between June and September with a frequency peak in July, and they were most frequent in Parque Estadual Morro do Diabo (PEMD) (350 m above sea level), where the sampling effort to catch each exemplar was 65.1 traps-day. From the sample of females of Monomachus captured in the Parque Estadual Intervales, Parque Estadual da Serra do Mar/Núcleo Santa Virgínia (PESM/NSV), PEMD and Estação Ecológica Juréia Itatins, between December 2009 and December 2010, two species were recognized: M. fuscator (N = 58/87.9%) and M. cubiceps (8/12.1%). In additional samplings in 2011 at PESM/NSV two exemplars of M. klugii recorded only from Rio de Janeiro State, Brazil were obtained, showing that its distribution has extended to São Paulo State.
