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

2(1) Flagellomeres 10-13 cubic. Head in dorsal view transverse, twice as broad as long, eye twice as long as temple and latter strongly rounded or constricted (Fig. 17). Marginal cell of fore wing along 1-R1 0.8 times as long as pterostigma (Fig. 20). Carapace in dorsal view broadest somewhat posteriorly (d: Figs 21) or medially (Ç: Fig. 24). Apical foramen of male carapace large, i.e. extending to about half hind end of carapace (Fig. 23). Tegula yellow or brown. Çd: 2.7-2.8 mm M. brasiliensis (BRUES) Microchelonus brasiliensis resembles somewhat M. johni (MARSH, 1979) (Colombia), however, they are clearly separated from each other by the features as follows: 1 (2) Temple striate, dull. Carapace strongly rugose and areolate particularly at base. Veins r and 3-SR of fore wing about equal in length (Fig. 7 in MARSH 1979: 13). Two pairs of of tubercules of propodeum strong. Çd: 3 mm M. johni (MARSH) 2(1) Temple more or less confluently punctate, interspaces glittering (Fig. 18). Carapace rugose (Fig. 21) to rugulose. Veins r and 3-SR of fore wing unequal in length, i.e. 3-SR almost twice as long as r (Fig. 20). Two pairs of tubercules of propodeum weak. Çd: 2.7-2.8 mm M. brasiliensis (BRUES) Microchelonus constrictus sp. n. Ç (Figs 26-31) Material examined (4 ?Ç) - Female holotype + two female paratypes: Argentina, Buenos Aires, Ramos Mejia, beaten from blossoming Solanacea and other plants on weedy ground, 9 December 1961, leg. TOPÁL (No. 766). - One female paratype: same locality as No. 766, 5 December 1961, leg. TOPÁL (No. 756). - Holotype and three paratypes are deposited in the Hungarian Natural History Museum (Department of Zoology, Budapest, Hym Typ. Nos 7845 (holotype) and 78467848 (paratypes). Etymology-The species name "constrictus" refers to the strongly rounded temple. Description of the female holotype - Body 3 mm long. Antenna as long as head and mesosoma combined and with 16 antennomeres. Scape twice as long as broad apically (Fg. 26). First flagellomere 2.4 times as long as broad apically, further flagellomeres progressively shortening so that flagellomeres 10-13 cubic (Fig. 27). - Head in dorsal view twice as broad as long, eye one-third longer than temple, latter strongly rounded (Fig. 28), occiput deeply excavated. Eye in lateral view twice as high as wide, temple ventrally broadening, beyond eye ventrally as wide as eye (cf. Fig. 3, see arrows). Clypeus 2.2 times as wide as high, its lower margin convex. Malar space 1.5 times as long as basal width of mandible. Head rugose, temple areolate-rugose. Mesosoma in lateral view 1.7 times as long as high, roughly rugose. Lateral pair of lobes at base of scutellum small, less distinct. Scutellum smooth and shiny. Caudal margin of propodeum defined by distinct transverse ridge, two pairs of projections weak. - Hind femur 3.1 times as long as broad medially. Fore wing as long as head, mesosoma and half of carapace combined. Pterostigma (Fig. 29) 2.5 times as long as wide and issuing r from its middle, /• clearly more than half as long as width of
