Papp, J.: Five new Microchelonus species from the Neotropical Region (Hymenoptera, Braconidae: Cheloninae)
Carapace somewhat shorter than head and mesosoma combined, in dorsal view (Fig. 14) somewhat belly and 1.6 times as long as broad medially; in lateral view 2.5 times as long as high behind and 1.7 times as high behind as basally (Fig. 15, see arrows within carapace). Carapace apico-laterally rounded (Fig. 15, see arrow outside carapace), apico-ventrally somewhat incurved (Fig. 16, see arrow). Carapace alutaeous rugulose (Fig. 14). Ovipositor sheath less short, about as long as hind tarsomeres 1-3. Body black. Scape brownish black, apically and basally faintly rusty; flagellum blackish. Palpi blackish. Tegula brownish black. Legs dark brown to brown, coxae and hind femur blackish brown. Wings hyaline, pterostigma brown and veins light brown to yellowish. Male and host unknown. Distribution - Argentina. Remarks - The new species, Microchelonus bolsoni, is nearest to M. topali sp. n. considering their body size, short marginal cell of fore wing, punctate and shiny temple, weak transverse caudal ridge of propodeum and dark colour of body + legs. The two species are distinguished by the following fetures keyed below: 1 (2) Temple in dorsal view more rounded and eye distinctly, i.e. 1.6 times as long as temple (Fig. 9). Pterostigma issuing r from its middle, marginal cell along J-RJ 0.5 times as long as length of pterostigma (Fig. 13). Hind femur 2.8 times as long as broad medially (Fig. 12). Carapace alutaceous rugulose (Fig. 14), in lateral view belly, 2.5 times as long as high posteriorly (Fig. 15, see arrows within carapace). Ç: 2.8 mm M. bolsoni sp. n. 2(1) Temple in dorsal view less rounded and eye less distinctly, i.e. 1.2 times as long as temple (Fig. 65). Pterostigma issuing r distally from its middle, marginal cell along I-Rl 0.6 times as long as length of pterostigma (Fig. 69). Hind femur 3.3 times as long as broad medially (Fig. 68). Carapace rugose (Fig. 70), in lateral view less belly, 2.9 times as long as high posteriorly (Fig. 71, see arrows within carapace). Ç: 2.8-2.9 mm M. topali sp. n. The new species, surprisingly, is similar to the European species M. brevis TOBIAS, 1976, their specific distinction is restricted to a few features only: 1 (2) Eye in dorsal view 1.6 times as long as temple, latter strongly rounded; vertex densely punctate (Fig. 9), temple punctate, interspaces polished (Fig. 10). Scutellum polished with a few punctures. Carapace rugose (Fig. 14). Caudal margin of propodeum not defined by transverse ridge. Wings hyaline. Ç: 2.8 mm M. bolsoni sp. n. 2 (1) Eye in dorsal view just longer than temple, latter rounded; vertex and temple densely uneven-subrugulose. Scutellum rugulose-uneven. Carapace alutaceous-rugulose. Caudal margin of propodeum defined by a transverse ridge. Wings subhyaline. Ç: 2.8-3 mm M. brevis TOBIAS
