A revision of Gasteruption Latreille (Hymenoptera: Gasteruptiidae) in the Neotropical Region 3030 Author Macedo, Antonio Carlos Cruz text Zootaxa 2011 2011-09-16 3030 1 1 62 https://biotaxa.org/Zootaxa/article/view/zootaxa.3030.1.1 journal article 10.11646/zootaxa.3030.1.1 1175­5334 5280554 Gasteruption wahli n. sp. ( Fig. 26 ) Etymology. The epithet for this species is in honor of Dr. David Wahl, curator of the American Entomological Institute. Diagnosis. Differs from G. barnstoni by the mesoscutum punctate rugulose ( Fig. 26c ); and the head wider than long ( Fig. 26a ). Differs from G. helenae by the metacoxa finely striate; the head wider than long; the propleuron with irregular striae; and the pronotum with the area between lobes usually crenulate (well-defined sculpture) ( Fig. 26d ). Differs from other Neotropical species by the occipital carina narrow dorsally and laterally ( Fig. 26b ); the mesepisternum ( Fig. 26d ) and the propodeum areolate; the ovipositor sheath longer than the metasoma, and dark brown, with apex yellow brown ( Fig. 26e ); and the fore wing discal cell present. Description. Female ( Fig. 26e ). Length: 15.7 mm (14.5–17.0 mm) (n=2); ovipositor sheath length 1.00 (0.90– 1.00) body length. Head. Subtrapezoidal in dorsal view, wider than long ( Fig. 26a ), punctulate, with fine irregular striae in vertex; 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. 26b ). Head length 1.24 (1.21–1.27) eye length; eye length 17.00 (16.00–18.00) malar space; distance from posterior ocellus to occipital margin 1.72 (1.56–1.88) distance between posterior ocelli; 1 st flagellomere 1.29 (1.25–1.33) as long as scape, 1.59 (1.36–1.82) as long as pedicel, 0.65 (0.63–0.67) as long as 2 nd flagellomere. Color: black, antenna black to dark brown. Mesosoma. Propleuron imbricate, with irregular striae; pronotal process distinct; pronotum imbricate rugulose, area between lobes crenulate; mesonotum rounded in lateral view ( Fig. 26d ); mesoscutum punctate rugulose (with fine irregular striae in some specimens) ( Fig. 26c ); mesoscutelum punctate rugulose; mesepisternum rugulose dorsally and areolate ventrally; mesepimeron scrobiculate; metapleuron areolate, ventral region rugulose; propodeum areolate, longitudinal carina indistinct; metacoxa finely striate. Mesosoma (excluding propleuron) 1.87 (1.78–1.96) as long as high; propleuron 1.50 (1.44–1.56) longer than its largest wide, 0.96 (0.92–1.00) pronotum length; metacoxa 3.14 (2.71–3.57) as long as wide; metatibia 5.38 (5.04–5.73) as long as wide, 1.42 (1.40–1.45) as long as femur, 2.74 (2.71–2.77) as long as 1 st tarsomere. Fore wing discal cell subtrapezoidal; hind wing with 3 hamuli, not equidistant. Color: propleuron and mesonotum black; pronotum, mesopleuron and metapleuron black (or with some red-brown parts); propodeum black; fore and middle legs with coxa, trochanter, femur and tibia dark brown, tibia with or without a yellow longitudinal stripe, tarsus dark brown (or partially yellow) in basal tarsomeres and dark brown in apical tarsomeres; hind leg with coxa black, trochanter, femur and tibia dark brown, subbasal portion of tibia yellow, 1 st tarsomere yellow, with base dark brown, 2 nd –3 rd yellow, 4 th –5 th dark brown. Metasoma. Imbricate, 3.25 (3.13–3.38) as long as mesosoma; subgenital sternun notched, Y-shaped; ovipositor sheath 1.45 (1.41–1.48) as long as metasoma. Color: dark brown; ovipositor sheath dark brown, with apex yellow brown. FIGURE 26.
