( Fig. 15 ) Etymology. The epithet for this species is in honor of Liana Kono Nogueira, my colleague in the Museu de Zoologia, Universidade de São Paulo . Diagnosis. Differs from other Neotropical species by the combination of the following characters: mesoscutum areolate rugose ( Fig. 15c ); occipital carina narrow dorsally and laterally ( Fig. 15b ); fore wing discal present; propleuron and mesonotum black, pronotum, mesopleuron and metapleuron red brown ( Fig. 15d ). Description. Female. Unknown. Male ( Fig. 15e ). Length: 13.9 ( 12.2–16.1 mm ) (n=6). Head. Subtrapezoidal in dorsal view, longer than wide ( Fig. 15a ), punctulate; mandible pre-apical tooth distinct; malar space short, almost separated from gena; posterior ocellus inserted at the level of upper eye margin; occipital carina narrow dorsally and laterally ( Fig. 15b ). Head length 1.55 (1.47–1.69) × eye length; eye length 20.22 (16.33–25.50) × malar space; distance from posterior ocellus to occipital margin 2.34 (2.00–2.73) × distance between posterior ocelli; 1 st flagellomere 0.96 (0.89–1.00) × as long as scape, 1.22 (1.11–1.43) × as long as pedicel, 0.56 (0.50–0.59) × as long as 2 nd flagellomere. Color: black, clypeus with anterior portion lighter than remaining. Mesosoma. Propleuron imbricate (with irregular striae in some specimens); pronotal process distinct; pronotum ventral lobe rugulose, dorsal and posterior lobes imbricate, area between lobes crenulate; mesonotum rounded in lateral view ( Fig. 15d ); mesoscutum areolate rugose ( Fig. 15c ); mesoscutelum rugulose; mesepisternum imbricate dorsally and areolate (or rugulose) ventrally; mesepimeron scrobiculate; metapleuron areolate, ventral region with a reduced smooth or rugulose portion; propodeum areolate, longitudinal carina distinct; metacoxa finely striate. Mesosoma (excluding propleuron) 2.06 (1.89–2.22) × as long as high; propleuron 2.09 (1.83–2.83) × longer than its largest wide, 1.34 (1.23–1.51) × pronotum length; metacoxa 2.85 (2.71–3.12) × as long as wide; metatibia 4.99 (4.78–5.29) × as long as wide, 1.43 (1.36–1.49) × as long as femur, 2.67 (2.53–2.83) × as long as 1 st tarsomere. Fore wing discal cell subtrapezoidal or subtriangular; hind wing with 3 hamuli, not or almost equidistant. Color: propleuron and mesonotum black; pronotum red brown; mesopleuron and metapleuron red brown (with some black areas in several specimens); propodeum black dorsally and red brown ventrally; fore and middle legs with coxa and trochanter dark brown, femur and tibia red brown to dark brown, with extremities lighter, tarsus yellow, with apical tarsomeres gradually darker than basal ones; hind leg with coxa black, trochanter, femur and tibia dark brown, subbasal portion of tibia yellow, tarsus dark brown.
