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

(Fig. 18, see arrows). Clypeus 1.5 times as wide as high, its lower margin medially truncate (Fig. 19). Face twice as wide as high. Malar space 1.3 times as long as basal width of mandible. Face transversely rugulose and dull; clypeus subrugulose and dull; frons and vertex transversely and just not confluently punctate, subshiny; occiput transversely puncto-rugulose (similar to face) and subshiny (Fig. 17); temple more or less confluently punctate, interspaces glittering (Fig. 18). Mesosoma in lateral view slightly longer than high, rugose, roughly rugose to scabrous, scutellum medially uneven. Lateral pair of lobes at base of scutellum absent. Caudal margin of propodeum defined by transverse ridge, two pairs of projections weak, outer pair somewhat stronger (Fig. 22). - Hind femur three times as long as broad medially. Fore wing about as long as antenna or as long as head, mesosoma and half of carapace combined. Pterostigma (Fig. 20) 2.1 times as long as wide and issuing r distally from its middle. Marginal cell of fore wing along 1-R1 0.8 times as long as pterostigma; 3-SR almost twice as long as r, 4-SR faintly S-form (or just not straight). Carapace somewhat shorter than head and mesosoma combined, posteriorly faintly broadening oval, in dorsal view 1.7 times as long as broad posteriorly (Fig. 21); in lateral view 3.1 times as long as high behind, 1.6 times as high behind as basally (Fig. 22, see arrows). Carapace anteriorly rugose (Fig. 21), posteriorly rugulose, dull; basal pair of keels extending to anterior fifth of carapace. Apical foramen of carapace elliptic, twice as wide as high, extending about half end of carapace (Fig. 23). Body black. Scape + pedicel yellow, flagellum blackish brown, below and distally with weakening yellowish tint. Palpi pale yellow. Tegula yellow. Colour of legs similar to those of M. topali, light colour yellow. Wings hyaline, pterostigma brown, basally with a small yellow macula, veins brownish yellow. Description of male specimens (3 dd) - Similar to the male holotype. Body 2.7-2.8 mm long. Antenna with 20 antennomeres, those of 17-19 1.3-1.2 times as long as broad. Scutellum medially either uneven (1 d) or smooth (2 dd). Apical foramen of carapace 2-2.2 times as wide as high. Scape reddish yellow, flagellum entirely blackish brown. Tegula brown. Pterostigma entirely brown. Description of female specimens (5 ÇÇ) - Similar to the male. Body 2.7-2.8 mm long. Antenna somewhat longer than fore wing and with 16 antennomeres. First flagellomere 2.5 times as long as broad apically, further flagellomeres progressively less shortening so that flagellomeres 1315 cubic. Scutellum smooth and shiny. Carapace apico-laterally rounded (Fig. 25, see arrow outside carapace), in lateral view 2.8 times as long as high behind and 1.4 times as high behind as basally (Fig. 25, see arrows within carapace). Ovipositor sheath in lateral view about as long as hind tarsomeres 1-2 combined. Palpi pale yellow, tegula brown. Host unknown. Distribution. - Brazil. Microchelonus brasiliensis (BRUES) stands nearest to M. topali sp. n. (Argentina), the two species are distinguished by the features keyed: 1 (2) Flagellomeres 8-13 1.5 times as long as broad. Head in dorsal view less transverse, 1.8 times (Ç) and 1.9 times (Ó ) as broad as long, eye only somewhat longer than temple and latter rounded (Fig. 65). Marginal cell of fore wing along 1-RI 0.6 times as long as pterostigma (Fig. 69). Carapace in dorsal view broadest medially (Fig. 70). Apical foramen of male carapace small, i.e. restricted to ventral part of hind end of carapace (Fig. 74). Tegula black. Çd: 2.8-2.9 mm M. topali sp. n.
