( Figs 58–62 )

Female. Body length: 2.6 mm.

Colour: head dark brown to black, palpi yellow, flagellum dark brown, scape yellow; mesosoma dark brown to black; metasoma brown, except the second tergum yellow; wing veins light brown, stigma dark brown; posterior legs pale yellow with femur brown and pale yellow at the base.

Head: vertex, frons and face smooth; malar space greater than ¼ eye height; temple narrow, width equal to ½ eye width; ocell-ocular distance 2.5 times the diameter of lateral ocellus; 15 flagellomeres.

Mesosoma: mesopleuron smooth, precoxal sulcus smooth, shorter than width of mesopleuron ; mesoscutum lobes weak granulose, hairy just along notauli; notauli scrobiculate meeting before prescutellar furrow in triangular costate area; prescutellar furrow with three cross carinae (one strong and two weak); scutellum weakly granulose; propodeum with basal median areas distinct and not margined, basal median areas granulose, basal median carina present, areolar margin indistinct, areolar area areolate-rugose, lateral areas entirely rugose, mesosternum smooth; hind coxa and femur with striations. Fore wing: vein r shorter than vein 3 RSa, vein 1cu-a interstitial with vein 1M, stigma wider to length of vein r. Hind wing: vein SC+R present, length of vein M+CU shorter than vein 1M.

Metasoma: first tergum longitudinally costate, apical width two times shorter than length; second tergum longitudinally costate, with apical width three times length; third tergum smooth; terga II+III with anterior and posterior transverse grooves absent; terga IV–VII smooth; ovipositor equal to ¾ length of metasoma.

Material examined. Holotype ( DCBU 31293 ); female, Brazil, SP, São Luiz do Paraitinga, Núcleo Santa Virgínia 23o19’27,1’’S 45o5’38,4’’W, semidecidous mesophilic forest, 22.I.2010, Malaise trap; N.W. Perioto col.
