Macedo, Antonio Carlos Cruz, 2011, A revision of Gasteruption Latreille (Hymenoptera: Gasteruptiidae) in the Neotropical Region 3030, Zootaxa 3030 (1), pp. 1-62 : 26-28

Gasteruption glauciae n. sp. ( Fig. 9 )

Etymology. The epithet for this species is in honor of Dr. Glaucia Marconato, my colleague in the Museu de Zoologia, Universidade de São Paulo, who made the drawings for this work, and also for Macedo (2009).

Diagnosis. Differs from G. masneri by the head as long as wide ( Fig. 9a ); the occipital carina narrow dorsally and laterally ( Fig. 9b ); the propleuron with irregular striae; and the propodeum longitudinal carina indistinct. Differs from other Neotropical species by the propodeum areolate; the mesoscutum imbricate, with very sparse punctation ( Fig. 9c ); the metacoxa striate; the occipital carina narrow dorsally and laterally; the head as long as wide; the hind tarsus partially yellow; the ovipositor sheath longer than the metasoma ( Fig. 9e ); and the fore wing discal cell absent.

Description. Female ( Fig. 9e ). Length: 14.4 mm (n=1); ovipositor sheath length 0.75 × body length.

Head. Subtrapezoidal in dorsal view, as long as wide ( Fig. 9a ), 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. 9b ). Head length 1.37 × eye length; eye length 15.00 × malar space; distance from posterior ocellus to occipital margin 1.77 × distance between posterior ocelli; 1 st flagellomere 1.15 × as long as scape, 1.67 × as long as pedicel, 0.65 × as long as 2 nd flagellomere. Color: black.

Mesosoma. Propleuron imbricate, with irregular striae; pronotal process distinct; pronotum imbricate, area between lobes crenulate; mesonotum rounded in lateral view ( Fig. 9d ); mesoscutum and mesoscutelum imbricate, with very sparse punctation ( Fig. 9c ); mesepisternum imbricate dorsally and areolate ventrally; mesepimeron scrobiculate; metapleuron areolate, ventral region with a reduced smooth portion; propodeum areolate, longitudinal carina indistinct; metacoxa finely striate. Mesosoma (excluding propleuron) 2.13 × as long as high; propleuron 1.83 × longer than its largest wide, 1.15 × pronotum length; metacoxa 2.91 × as long as wide; metatibia 4.80 × as long as wide, 1.47 × as long as femur, 2.88 × 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 black, trochanter, femur and tibia dark brown, tibia with a yellow longitudinal stripe, tarsomeres 1–2 yellow, remaining tarsomeres black; hind leg with coxa and trochanter black, femur and tibia dark brown, subbasal portion of tibia yellow, 1 st tarsomere yellow, with base dark brown, 2 nd yellow, 3 rd –5 th dark brown.

Metasoma. Imbricate, 2.85 × as long as mesosoma; subgenital sternun notched, Y-shaped; ovipositor sheath 1.22 × as long as metasoma. Color: metasoma black; ovipositor sheath dark brown, with apex yellow brown.

Male. Unknown.
