Description. Holotype female ( Fig. 1 ). Head with antenna stout and 52 flagellomeres; interocellar distance 1.5 times orbital-ocellar distance; lateral ocellus separated from eye by 0.75 times its own diameter; malar space 0.5 times as long as basal width of mandible ( Fig. 3 ); occipital carina moderately developed mediodorsally, slightly broadened lateroventrally. Mesoscutum more or less uniformly punctate, except the notaular region with coarser and irregular rugae ( Fig. 4 ); scutellum bearing long and dense yellow pubescence, rugose, with irregular lateral longitudinal rugae ( Fig. 5 ). Mesopleuron striate diagonally, with speculum mostly smooth and polished, the ventral area rugose to coarsely punctate; sternaular groove complete and strongly impressed. Posterior transverse carina of mesosternum lateromedially weakly produced into rounded lobes that are separated by a shallow concavity. Propodeum rugose-reticulate, with apophyses strongly developed, higher than broadly basally; upper rim of hind coxal socket with a distinct apophysis-like projection. Hind tibia strongly compressed, hind basitarsus 1.2 times as long as segments 2-5; hind tarsal claw pectinate, but with a large space in the middle, distinctly longer than the arolium ( Fig. 6 ). Forewing length 15 mm, with areolet more or less triangular and not petiolate above; hind wing with 8 hamuli. Ovipositor short, 0.2 times hind tibia.

Head and mesosoma black, except mouthparts yellow; tegula yellow anteriorly and blackish posteriorly. Anterior two pairs of legs predominantly yellow, femur and distal tarsal segment orange, mid coxa slightly infuscate. Hind leg with coxa black, trochanteral segments and femur reddish, blackish distally; tibia black at proximal and distal apices and centrally broadly yellow; tibial spurs and tarsus yellow with distal segment slightly orange. Metasoma with tergites I and II entirely black, segments III and IV anteriorly black, and the remaining reddish. Membrane wings more or less hyaline, with a very weak trace of blackness.

Male ( Fig. 2 ). Similar to female except by hind leg with coxa almost entirely reddish, tibia all black with a thin yellow line, basitarsus black and the following tarsomeres black dorsally.

Distribution ( Fig. 7 ). BRAZIL: São Paulo (São Luiz do Paraitinga and Ribeirão Grande). Specimens of the new species were collected throughout the wet season in southeast Atlantic Forest habitats

Hosts. Unknown

Etymology. The specific name (adjective, gender masculine) refers to the Atlantic Forest Biome, where the specimens were collected.

Material examined. Holotype: 1 female ( DCBU 39967 ), BRASIL, São Paulo: São Luiz do Paraitinga ( Parque Estadual da Serra do Mar , Malaise 2, 23°19’27.2”S, 45°05’38.5”W), 22.III.2010, N.W. Perioto e eq. col . Paratypes: 1 female ( MZSP 53326 ), same data as holotype ; 1 male ( DCBU 35359 ) same data as holotype, except, Malaise 1, 23°19’27.1”S, 45° 05”38.4”W, 22.XII.2010 ; 1 male ( MZSP 53327 ) same data as holotype, except, Malaise 6, 23°19’24.8”S, 45°05’40.1”W, 21.XII.2010 ; 1 female ( DCBU 39968 ), Ribeirão Grande, Parque Estadual Intervales , Malaise 1, 24°16’28”S, 48°25’14.8”W, 22.III.2010, N.W. Perioto e eq. col .

Remarks. The specimens of Cryptophion atlanticus sp. nov. match the diagnosis of the genus and can be distinguished from all other Cryptophion by the following combination of characters: mesoscutum more or less uniformly punctate, except the notaular region with coarser and irregular rugae, scutellum bearing irregular lateral longitudinal rugae; forewing with areolet not distinctly petiolate above and hind tarsal claw pectinate, but with a large space in the middle, distinctly longer than the arolium. It differs from the other two Brazilian species also by the hind tarsal claw simple, the presence of a distinct lateral longitudinal carina on scutellum, extending for about half of its length, and the white color of its pubescence in C. guillermoi Gauld & Janzen, 1994, and by the interocellar distance 2.0- 2.2 times the orbital-ocellar distance, hind tarsal claw with a single subapical pectinal tooth, small and not distinctly longer than arolium in C. espinozai Gauld & Janzen, 1994 . The Central American Cryptophion inaequalipes ( Cresson, 1874) also has a distinct pectinate claw, but differs easily from the new species by the scutellum with a strong lateral longitudinal carina extending for about half of its length raised into tubercles posteriorly, thus scutellum is pyramidal in lateral view.
