n. sp.

Gasteruption masneri   n. sp. ( Fig. 17 View FIGURE 17 )

Etymology. The epithet for this species is in honor of Dr. Lubomir Masner, Canadian National Collection of Insects, who collected the unique specimen of this species.

Diagnosis. Differs from G. glauciae   by the head wider than long ( Fig. 17a View FIGURE 17 ); the occipital carina narrow dorsally and wider laterally ( Fig. 17b View FIGURE 17 ); the propleuron without striae; and the propodeum longitudinal carina distinct. Differs from other Neotropical species by the propodeum areolate; the mesoscutum punctulate ( Fig. 17c View FIGURE 17 ); the metacoxa striate; the occipital carina narrow dorsally and wider laterally; the head wider than long; the hind tarsus partially yellow; the ovipositor sheath longer than the metasoma ( Fig. 17e View FIGURE 17 ); and the fore wing discal cell absent.

Description. Female ( Fig. 17e View FIGURE 17 ). Length: 12.6 mm (n=1); ovipositor sheath length 0.94 × body length.

Head. Subtrapezoidal in dorsal view, wider than long ( Fig. 17a View FIGURE 17 ), 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 wider laterally ( Fig. 17b View FIGURE 17 ). Head length 1.17 × eye length; eye length 29.00 × malar space; distance from posterior ocellus to occipital margin 1.54 × distance between posterior ocelli; 1 st flagellomere 1.00 × as long as scape, 1.50 × as long as pedicel, 0.48 × as long as 2 nd flagellomere. Color: black, clypeus with anterior portion lighter than remaining, antenna dark brown.

Mesosoma. Propleuron imbricate; pronotal process distinct; pronotum imbricate, area between lobes crenulate; mesonotum rounded in lateral view ( Fig. 17d View FIGURE 17 ); mesoscutum and mesoscutelum punctulate ( Fig. 17c View FIGURE 17 ); mesepisternum imbricate dorsally and areolate ventrally; mesepimeron scrobiculate; metapleuron areolate, ventral region with a reduced smooth portion; propodeum areolate, longitudinal carina distinct; metacoxa finely striate. Mesosoma (excluding propleuron) 1.86 × as long as high; propleuron 1.63 × longer than its largest wide, 1.05 × pronotum length; metacoxa 2.52 × as long as wide; metatibia 4.80 × as long as wide, 1.45 × as long as femur, 3.33 × as long as 1 st tarsomere. Fore wing discal cell absent; hind wing with 3 hamuli, not equidistant. Color: black; fore and middle legs with coxa, trochanter, femur and tibia dark brown, tibia with a yellow longitudinal stripe, tarsus yellow; hind leg with coxa black, trochanter, femur and tibia dark brown, subbasal portion of tibia yellow, 1 st tarsomere yellow, with base dark brown, remaining tarsomeres yellow.

Metasoma. Imbricate, 3.19 × as long as mesosoma; subgenital sternun notched, Y-shaped; ovipositor sheath 1.47 × as long as metasoma. Color: dark brown dorsally and yellow brown ventrally; ovipositor sheath dark brown, with apex yellow brown.

Male. Unknown.
