Mesosoma orange, except anterior region of pronotum blackish. Metasoma orange, with posterior margin of tergite V and tergites VI+ black. Anterior and mid leg entirely orange, the hind leg orange, with femur, except base, tibia and tarsus blackish. Wings yellowish; fore wing with apex distal to 2 rs-mblack, and with a black median band extending backwards from anterior margin, just proximal to the pterostigma, right through the 1 stsubdiscal cell; pterostigma yellowish. Ovipositor brownish, except basal region orange and apex slightly brownish, sheath dark brown.  Male.( Figs 11–12). Similar to female in structure and coloration, except body 9.0–11.0 mm; lower face 1.1– 1.2× as broad as high (from supraclypeal suture to base of antenna); head in dorsal view with margin of gena flat behind eyes; margin of gena 0.6–0.8× length of eye in dorsal view; posterior ocelli separated from eyes by 0.85× its diameter in dorsal view; fore wing 7.0–9.0 mm; tergite I 1.1–1.4× as long as posteriorly broad; tergite II 1.0–1.1× as long as posteriorly broad; tergite III 0.9–1.3× as long as posteriorly broad; sternite IX ( Fig 14) longer than high, with lateral and anterior margins strongly sclerotised, lateral margin flat and posterior margin concave centrally, with few bristles widely spaced posteriorly. Genital capsule ( Figs 15–16): Paramere truncated apically, slightly narrower than the parameral lamina, with bristles except in posterior margin; volsellar lamina with spaced bristles medially and apically, except in the inner margin and posterior part and with a set of three to five bristles in anterolateral region, just below the base of the digitus; cuspis robust with about five to six teeth aligned in the mid part until apex and with two to four few bristles in basal region and spaced laterally in apical region; digitus with teeth in apex, rounded distally and angular ventrally, with the margins of the apical region narrower than base; aedeagus with few teeth on apex and its apex slightly curved downward in lateral view.  Variation.Some specimens with hind femur with proximal half orange and distal half black or hind femur orange with distal 0.4 black.   Type material:   Holotype: ♀, BRAZIL, RR[= Roraima], Amajari, Tepequém,  14–29.xii.2015, Malaiselarge [model Gressit& Gressit, 1962], Project Bionorte( J.A.
