Duas novas espécies de Dryinidae ( Hymenoptera : Chrysidoidea ) de áreas de Mata Atlântica do Estado de São Paulo , Brasil

Two new species of Dryinidae are described and illustrated: Dryinus auratus Martins, Lara, Perioto & Olmi sp. nov. and Gonatopus mariae Martins, Lara, Perioto & Olmi sp. nov., both from areas of Atlantic Rainforest at São Paulo State, Brazil. Keys to species are provided.

Dryininae comprises about 340 species distributed in nine genera, of which five are reported for the Neotropics; Dryinus Latreille, 1804 are present in all zoogeographical regions and comprise about 290 species (Olmi et al., 2011;Olmi and Virla, 2014), of which about 120 are reported from the Neotropics and about 40 from Brazil (Olmi, 2009;Coelho et al., 2011;Olmi and Virla, 2014).Dryinus is divided into four species-group: autumnalis, constans, lamellatus and ruficauda (Olmi et al., 2011).Dryinus of the constans group (group 1 of Olmi and Virla, 2014), comprises about 40 species, 12 from Brazil and it is characterized by the notaulice at least partly visible and enlarged claw, much longer than arolium, with one subapical tooth and never with a broad apical lamella (Olmi et al., 2011;Olmi and Guglielmino, 2011;Olmi and Virla, 2014).
Gonatopodinae has cosmopolitan distribution and about 560 species distributed in nine genera, eight reported for the Neotropical region.Gonatopus Ljungh, 1810, also cosmopolitan, has about 440 species divided into 12 groups of species, 160 species are reported from the Neotropics and 30 from Brazil (Olmi and Virla, 2014).
This study aimed to describe new species of Dryinus and Gonatopus collected in áreas of Atlantic Rainforest at São Paulo State, Brazil.
Observations and descriptions were made using a Leica MZ 9.5 stereomicroscope; the colour images were obtained with Leica DFC295 digital camera attached to a Leica M205C APO stereomicroscope; specimens were illuminated with high diffuse dome illumination Leica LED5000 HDI.The serial images from different layers were combined with Helicon Focus software (version 5.3).Digital scanning electronmicroscope (SEM) photographs weret aken with a FEI Quanta TM 250 SEM in low vacum mode.The figures were prepared using Adobe Photoshop (version 11.0).
The morphological terminology follows Olmi and Virla (2014), except for the forewing radial vein, herein termed as Rs; the integument sculpture follows Eady (1967).
The identifications were made using the keys proposed by Olmi (2006) and Olmi and Virla (2014).
