Tuberepyris hamus Azevedo et Mugrabi , sp. nov.

( Figs 7–9 , 23–25 )

Description. Female. Body length 2.5 mm. LFW 1.5 mm. Body entirely flattened, head 0.36x as high as long in lateral view. Color. Head and mesosoma dark castaneous almost black; legs (except tarsi), metasoma dark castaneous; antenna, mandible, wing venation castaneous; palpi, tarsi light castaneous; wings subhyaline.

Head ( Figs 7–9 ). Mandible wide apically, with four visible sharpened apical teeth; lowermost one distinctly larger. Clypeus short; slightly projected, median lobe trapezoidal with rounded corner, medially elevated, but not carinate. Suture fronto-clypeal present. Eye slightly bulging laterad, with minute and sparse setae. First four antennomeres in ratio of about 37:16:8:10; flagellomere I about as long as wide; flagellomere IX distinctly longer than wide. Frons coriaceous with just few small and shallow punctures. LH 1.07x WH; WF 0.91x HE; VOL 0.6x HE; OOL 1.29x WOT. Frontal angle of ocellar triangle obtuse; ocellar triangle almost touching vertex. Vertex badly convex; corner rounded. Side of head behind eye slightly diverging anterad. Occipital carina absent. First two maxillar palpomeres distinctly shorter and wider than others, III-IV distal ones progressively wider apicad. Labial palpomeres shorter than maxillar ones.

Mesosoma ( Fig. 7–9 ). Pronotal disc with top surface 1.87x as long as mesoscutum; ecarinate. Pronotal collar without groove. Mesoscutum with parapsidal furrow narrow, straight, absent on anterior third of mesoscutum. Mesoscutum-mesoscutellar sulcus narrow, angled laterally. Forewing fully developed; 3.05x as long as wide; subcostal vein 0.28x as long as LFW; median vein present in apical region, 0.3x as long as subcostal vein; pterostigma small and subtriangular ( Fig. 23 ). Hind wing with three distal hamuli ( Fig. 25 ). Propodeal disc areolate-coriaceous, 1.12x as long as median width, progressively narrowing posteriorly; transverse posterior and lateral carinae present; median carina complete and well-defined; lateral of propodeum areolate-coriaceous with circular spiracles; declivity of propodeum areolate-coriaceous without median or lateral carinae. Anterior margin of propleuron almost reaching anterior margin of pronotal disc level in dorsal view. Mesopleuron ( Fig. 23 ) with subtegular groove poorly outlined; lower and anterior foveae absent, mesopleural pit slightly deep. Profemur 2.25x longer than wide.

Metasoma. Not petiolate; polished; 1.28x longer than mesosoma. Tergite II short, only 0.76x as long as tergite I, posterior margin slightly excavated medially.

Male unknown.
