Diagnosis. Differs from G. townesi by the mesoscutum punctate ( Fig. 10c ). Differs from other Neotropical species by the propodeum with ill-defined areoles, almost smooth laterally (as in Fig. 27d ); the metapleuron with a large smooth portion ventrally ( Fig. 10d ); the ovipositor sheath longer than the metasoma, and dark brown, with apex yellow brown ( Fig. 10e ); and the fore wing discal cell discal cell present.

Redescription. Female ( Fig. 10e ). Length: 13.6 mm (n=1, female from CNCI); ovipositor sheath length 0.86 × body length.

Head. Subtrapezoidal in dorsal view, as long as wide ( Fig. 10a ), 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 relatively wide dorsally and laterally ( Fig. 10b ). Head length 1.27 × eye length; eye length 31.5 × malar space; distance from posterior ocellus to occipital margin 1.79 × distance between posterior ocelli; 1 st flagellomere 1.08 × as long as scape, 1.44 × as long as pedicel, 0.51 × as long as 2 nd flagellomere. Color: black, clypeus with anterior portion lighter than remaining (apical flagellomeres lighter in some specimens).

Mesosoma. Propleuron imbricate (with irregular striae in some specimens); pronotal process distinct; pronotum imbricate to smooth, area between lobes crenulate; mesonotum rounded in lateral view ( Fig. 10d ); mesoscutum punctate ( Fig. 10c ); mesoscutelum punctate rugulose; mesepisternum imbricate dorsally and with ill-defined areoles ventrally; mesepimeron scrobiculate; metapleuron rugulose, ventral region with a large smooth portion; propodeum with ill-defined areoles, almost smooth laterally, longitudinal carina distinct (or ill-defined); metacoxa finely striate. Mesosoma (excluding propleuron) 1.92 × as long as high; propleuron 1.93 × longer than its largest wide, 1.24 × pronotum length; metacoxa 3.42 × as long as wide; metatibia 5.44 × as long as wide, 1.49 × as long as femur, 3.22 × as long as 1 st tarsomere. Fore wing discal cell subtriangular or subtrapezoidal; hind wing with 3 hamuli, not equidistant. Color: propleuron and mesonotum black; pronotum, mesopleuron and metapleuron red brown; propodeum black near metasoma insertion, red brown in remaining portions; fore and middle legs with coxa, trochanter, femur and tibia dark brown, tibia with a yellow longitudinal stripe, tarsus yellow, with apical tarsomeres gradually darker than basal ones; hind leg with coxa, trochanter, femur and tibia dark brown, subbasal portion of tibia yellow, proximal half of 1 st tarsomere dark brown, distal half yellow, remaining tarsomeres dark brown.

Metasoma. Imbricate, 3.24 × as long as mesosoma; subgenital sternun notched, Y-shaped; ovipositor sheath

1.33 × as long as metasoma. Color: metasoma dark brown; ovipositor sheath dark brown, with apex yellow brown.

Male. Similar to female; hind tarsus entirely dark brown.
