Papp, J.: Five new Microchelonus species from the Neotropical Region (Hymenoptera, Braconidae: Cheloninae)

Mesosoma in lateral view 1.7 times as long as high, areolate-rugose, mesonotum rugose, laterally rugulose, notaulix distinct and with crenulae. Scutellum invisible owing to the micropin. Caudal margin of propodeum defined by transverse ridge, two pairs of projections small. - Hind femur 4.1 times as long as broad medially (Fig. 38). Fore wing almost as long as body. Pterostigma (Fig. 39) less wide, 2.6 times as long as wide, issuing r proximally from its middle, r just longer than half width of pterostigma and just shorter than 3-SR, 4-SR straight. Marginal cell along 1-R1 almost as long as length of pterostigma. Carapace elongate, as long as head and mesosoma combined, in dorsal view 2.4 times as long as broad posteriorly, hardly broadening posteriorly and rounded apically (Fig. 40); in lateral view 3.1 times as long as high behind, 1.8 times as high behind as basally (Fig. 41, see arrows); in ventral view somewhat incurved apically (Fig. 42, see arrow). Anterior two-thirds of carapace strio-rugose (Fig. 40), posteriorly rugose. Apical foramen rather semicircular, 2.1 times as wide as high (Fig. 43). Body black. Scape reddish yellow, pedicel brownish, flagellum blackish. Palpi and tegula brown. Dark colour of legs 1-2 brown, leg 3 blackish; reddish yellow: coxae, femora 1-2 basally and apically, tibiae 1-2 (outer-distal part of tibia 2 brownish); basal third of hind tibia yellowish; tarsi brownish. Proximal half of fore wing hyaline, its distal half subfumous; hind wing hyaline. Female and host unknown. Distribution - Peru. Up to this time no Microchelonus species has been known in the Neotropical Region with elongate carapace coupled with body length over 4 mm. From among the Nearctic species of Microchelonus and with the help of McCOMB's key (1968) M. peruensis (SHENEFELT) is nearest to M. carinatus (PROVANCHER, 1881) (Canada, USA) considering their elongate carapace (0.4 times as broad as long), their specific differences are summarized as follows: 1 (2) Temple in dorsal view slightly bulged (Fig. 44). Eye in lateral view twice as high as wide, temple slightly wider than eye (Fig. 45, see arrows). Pterostigma narrow (Fig. 46), 3.1-3.2 times as long as wide and issuing r distally from its middle. Hind femur 3.3 times as long as broad medially (Fig. 47). Apical foramen of carapace at least three times as wide as high. Femora reddish yellow or testaceous. Wings fumous. 6: 4.7-6 mm M. carinatus (PROVANCHER) 2(1) Temple in dorsal view strongly rounded (Fig. 36). Eye in lateral view somewhat reniform, 1.6 times as high as wide and somewhat wider than temple (Fig. 37, see arrows). Pterostigma less narrow (Fig. 39), 2.6 times as long as wide and issuing r proximally from its middle. Hind femur 4.1 times as long as broad proximally (Fig. 38). Apical foramen of carapace 2.3 times as wide as high. Femora brown, only basally and apically reddish yellow. Wings hyaline, fore wing distally subfumous. 6: 4.1 mm M. peruensis (SHENEFELT)
