Papp, J.: Five new Microchelonus species from the Neotropical Region (Hymenoptera, Braconidae: Cheloninae)
pterostigma; 3-SR longer than r, 4-SR faintly S-like (Fig. 29), marginal cell along 1-R1 one-fourth shorter than length of pterostigma. Carapace about as long as head and mesosoma combined; in dorsal view (Fig. 30) 1.8 times as long as broad medially; in lateral view three times as long as high behind and 1.35 times as high behind as basally (Fig. 31, see arrows within carapace). Carapace apico-laterally rounded (Fig. 31, see arrow outside carapace), apico ventrally not incurved. Carapace rugose (Fig. 30). Ovipositor sheath short, concealed. Body black. Scape, pedicel and first flagellomerc reddish yellow, flagellomeres 2-4 darkening reddish yellow, rest of flagellum blackish. Palpi brownish yellow. Tegula reddish yellow. Legs reddish yellow, coxae 1-2 with faint brownish tint, coxa 3 black to blackish. Wings proximally hyaline, distally subfumous, pterostigma and veins brown. Description of the female paratypes (3 ÇÇ). - Similar to the female holotype. Body 3-3.3 mm long (3: 1 Ç, 3.1: 1 Ç, 3.3: 1 Ç). Scape, pedicel and first flagellomere with brownish tint (1 Ç). Palpi brownish or reddish yellow. Scutellum at most with a few subpunctures (1 Ç). Pterostigma 2.3 times as long as wide and issuing r somewhat proximally from its middle (1 Ç). Male and host unknown. Distribution - Argentina. With the help of MCCOMB'S key (1968: 4-14) to the Microchelonus species of the Nearctic Region the new species, M. constrictus sp. n., runs to M. paululus (McCOMB, 1968) (USA: Florida) on one hand and, but, on the basis of the holotype, it is very near to M. townsendi (VIERECK, 1912) (Peru), on the other. The three species are distinguished below: Figs 26-35. 26-31. Microchelonus constrictus sp. n.: 26 = scape, 27 = flagellomeres 8-14, 28 = head in dorsal view with indication of its sculpture, 29 = distal part of right fore wing, 30 = carapace in dorsal view with indication of its sculpture, 31 = carapace in lateral view. - 32-35. Microchelonus paululus (MCCOMB): 32 - head in dorsal view with indication of its sculpture, 33 = flagellomeres 9-14, 34 = distal part of right fore wing, 35 = carapace in dorsal view with indication of its sculpture
