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

Microchelonus bolsoni sp. n. Ç (Figs 9-16) Material examined (1 Ç) - Female holotype: Argentina: prov. Rio Negro, El Bolsón, forehill of Mt. Piltriquitron, 360 m, beaten from blossoming Fabiana imbricata bushes, 4 November 1961, leg. TOPÁL (No. 695). - Holotype is deposited in the Hungarian Natural History Museum (Department of Zoology) Budapest, Hym. Typ. No. 7844. Etymology - The new species received its name after its type locality. Description of the female holotype - Body 2.8 mm long. Antenna as long as head and mesosoma combined and with 16 antennomeres. First flagcllomere 3.3 times as long as broad apically, further flagellomeres progressively shortening so that flagellomeres 11-13 subcubic, i.e. 1.2 times as long as broad. - Head in dorsal view (Fig. 9) transverse, twice as broad as long, eye distinctly, i.e. 1.7 times as long as temple, temple strongly rounded, occiput excavated. Eye in lateral view 1.9 times as high as wide, temple beyond eye faintly broadening ventrally and somewhat wider than eye (Fig. 10, see arrows). Clypeus 2.3 times as wide as high, its lower margin truncate (Fig. 11). Face twice as wide as high. Malar space 1.8 times as long as basal width of mandible. Face with fine and dense punctation, interspaces smaller than punctures and subshiny; clypeus very finely and dispersely subpunctate, interspaces greater than punctures, polished. Vertex with dense and more or less confluent punctation (Fig. 9). Temple punctate, interspaces more or less greater than punctures and polished (Fig. 10). Mesosoma in lateral view 1.35 times as long as high, rugose to roughly rugose, scutellum polished and with a few subpunctures. Lateral pair of lobes at base of scutellum absent. Caudal margin of propodeum almost not defined by transverse ridge, two pairs of projections weak. - Hind femur relatively thick, 2.8 times as long as broad medially (Fig. 12). Fore wing as long as head, mesosoma and one-third of carapace combined. Pterostigma (Fig. 13) 2.5 times as long as wide, issuing r from its middle, /• half as long as width of pterostigma, r and 3-SR not entirely straight; marginal cell along 1-Rl half, i.e. 0.5 times as long as length of pterostigma.
