Papp, J.: Five new Microchelonus species from the Neotropical Region (Hymenoptera, Braconidae: Cheloninae)
Microchelonus subplanus sp. n. Çd (Figs 48-61) Material examined (1 Ç + 2 dd) - Female holotype: Costa Rica, Surrubes. - Two male paratypes: Honduras, Yoro, Palo de Comba, 15°11N'-87°39'W, 5 August 1995 (1 d) and 12 September 1995 (1 d), leg. R. CAVE. - Holotype and one paratype are deposited in the Hungarian Natural History Museum (Department of Zoology), Budapest, Hym. Typ. Nos 7849 (holotype) and 7850 (paratype). One paratype is deposited in the Zoological Museum, Lund. Etymology - The species name "subplanus" refers to the apically somewhat flattened (or truncate) carapace. Description of the female holotype - Body 3.3 mm long. Antenna as long as head, mesosoma and two-thirds of carapace combined. First flagellomere 3.3 times as long as broad apically, further flagellomeres progressively shortening and attenuating so that penultimate flagellomere twice as long as broad (Fig. 48). - Head in dorsal view (cf. Fig. 2) twice as broad as long, eye 1.7 times as long as temple, latter rounded, occiput excavated. Eye in lateral view 2.3 times as high as wide, beyond eye temple distinctly broadening ventrally and somewhat wider than eye (Fig. 49, see arrows). Clypeus 1.7 times as wide as high, its lower margin medially truncate (Fig. 50). Face twice as wide as high. Malar space 1.5 times as long as basal width of mandible. Face transversely striorugose, clypeus densely and finely punctate, subshiny, vertex + occiput transversely aciculate, temple densely punctate and subshiny (Fig. 49). Mesosoma in lateral view 1.4 times as long as high, areolate-rugosc. Lateral pair of lobes at base of scutellum small, pointed (Fig. 51, see arrows). Scutellum roughly rugose (Fig. 51). Caudal margin of propodeum defined by a less strong transverse ridge, both pairs of projections (or tubercules) also less strong. - Hind femur 3.1 times as long as broad medially (Fig. 52). Fore wing about as long as antenna or as long as head, mesosoma and two-thirds of carapace combined. Pterostigma (Fig. 53) 2.5 times as long as wide, issuing r just distally from its middle, r shorter than half width of pterostigma, 3 SR 1.6 times as long as /•. Marginal cell along 1-RI almost as long as pterostigma; 4-SR straight. Carapace shorter than head and mesosoma combined, in dorsal view (Fig. 54) 1.85 times as long as broad behind, broadest at its hind fourth; in lateral view 2.7 times as long as high behind and 1.7 times as high behind as basally (Fig. 55, see arrows within carapace), apically somewhat rounded (Fig. 55, see arrow outside carapace); apico-ventrally somewhat incurved (Fig. 56). Carapace anteriorly rugose with longitudinal striate elements (Fig. 54), posteriorly rugose to rugulose. Ovipositor sheath short and concealed. Apical end of carapace with a very small elliptic foramen (Fig. 57). Body black. Scape reddish yellow, pedicel brownish, flagellum blackish, flagellomeres 1-5 with progressively weakening reddish yellow tint. Palpi pale brownish. Tegula blackish brown. Coxae and femora brownish black, trochanters brownish yellow, fore tibia reddish yellow, tibiae 23 dark brown, tarsi brownish fumous. Wings hyaline, fore wing around pterostigma widely subfumous, pterostigma dark brown, veins brown. Description of the male paratypes (2 dd) - Similar to the female holotype. Body 3.3 mm long. Antenna nearly as long as body and with 22 antennomeres. First flagellomere three times and penultimate flagellomere 1.6 times as long as broad apically. Hind femur 2.8-2.9 times as long as broad medially (Fig. 58). Carapace in dorsal view 2-2.2 times as long as broad behind and less broadening posteriorly, its sculpture somewhat stronger (Fig. 59); in lateral view rather truncate apically (Fig. 60). Apical foramen of carapace small and elliptic, somewhat larger than that of female (Fig. 61).
