Description
Summary:Derecyrta araucariae spec. nov. is described from Southern Brazil. This woodboring sawfly emerged from dead Araucaria angustifolia (Bert.) O. Kuntze branches (Araucariaceae), collected up to 10 m above ground level in São Francisco de Paula, Rio Grande do Sul, Brazil. Larvae also were found within the wood and, therefore, it is the first confirmed record of a neotropical sawfly developing in a gymnospermous host. Our sample of 42 adults is the largest known series of a Derecyrta species, permitting for the first time a detailed description, including intraspecific variation. Since all adults were female, this species may reproduce parthogenetically.
