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

Mesosoma in lateral view 1.4 times as long as high, rugose to roughly rugose; mesonotum anteriorly with small polished fields, scutellum strongly punctate. Lateral pair of lobes at base of scutellum absent. Caudal margin of propodeum defined by weak transverse ridge, two pairs of pro­jections weak, outer pair somewhat stronger. - Hind femur 3.3 times as long as broad medially (Fig. 68). Fore wing about one-fourth shorter than body. Pterostigma (Fig. 69) 2.3 times as long as wide and issuing r distally from its middle. Marginal cell of fore wing along 1-R1 0.6 times as long as pterostigma, 3-SR twice as long as r, 4-SR straight. Carapace somewhat shorter than head and mesosoma combined, oval and 1.7 times as long as broad medially (Fig. 70); in lateral view 2.9 times as long as high behind and 1.3 times as high be­hind as basally (Fig. 71, see arrows within carapace). Carapace apico-laterally rounded (Fig. 71, see arrow outside carapace), carapace apico-ventrally somewhat incurved (cf. Fig. 16). Carapace ru­gose, basally with striate-longitudinal elements, dull. Ovipositor sheath short, concealed. Body black, antenna brownish black. Palpi blackish. Tegula black, subtegula brown. Legs blackish, femora 1-2 apically and tibiae 1-2 entirely brownish yellow, basal two-thirds of hind tibia brownish yellow, apically brown, tarsi brownish. Wings hyaline, pterostigma brown, veins yellowish brown. Description of the female paratypes (3 ÇÇ) - Similar to female holotype. Body 2.8-2.9 mm long. Penultimate flagellomere 1.4 times (1 Ç) and 1.2 limes (1 Ç) as long as broad to cubic (1 Ç). Temple with weak striate elements near eye. Description of the male paratypes (15 dd) - Similar to the females. Body 2.8-2.9 mm long. Antenna with 19-21, usually 20, antennomeres (19; 3, 20:11, 21: 1). Face with silvery pubescence. Temple near temporal carina with more or less sriate elements. Carapace in dorsal view less broad, twice as long as broad medially, apically somewhat pointed (Fig. 72); ventrally incurved (Fig. 73, see arrow). Apical foramen of carapace oval and 1.7-1.9 times as wide as high (Fig. 74). Scape (except brownish dorsal macula) and pedicel entirely reddish yellow, flagellomeres 1 —2(— 3) ven­trally reddish yellow or brownish yellow. Palpi brown to brownish. Host unknown. Distribution - Argentina. The new species, Microchelonus topali sp. n., stands nearest to M. tnasoni (McCOMB, 1968) (USA: California) and to M. johni (MARSH, 1979) (Colombia), the three species are distinguished by the features keyed: 1 (2) Flagellomeres 8-13 cubic, i.e. as broad as long. Caudal ridge of propodeum defined by a strong transverse ridge, median and lateral pairs of projections strong. Light colour of legs honey yellow. Çd: 3 mm M. johni (MARSH) 2 (1) Flagellomees 8-13 not cubic, i.e. at least 1.5 times as long as broad. Caudal ridge of propodeum defined by a weak transverse ridge, both pairs of projections less strong. Light colour of legs brownish or reddish yellow. 3 (4) Head in dorsal view (Fig. 65) relatively less transverse, 1.8 times (Ç) and 1.9 times (d) as broad as long, temple rounded. Temple in lateral view somewhat broadening ventrally, beyond eye somewhat wider than greatest width of eye (Fig. 66, see ar­rows); temple punctate, interspaces shiny (Fig. 66). Hind femur black. Çd: 2.8-2.9 mm M. topali sp. n.
