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

Redescription of the female holotype - Body 3 mm long. Antenna about as long as head and mesosoma combined and with 16 antennomeres. Scape 2.1 times as long as broad (Fig. 77): first flagellomere three times as long as broad, further flagellomeres progressively shortening and attenuating so that tenth flagellomere 1.6 times, eleventh flagellomere 1.4 limes as long as broad, twelfth and thirteenth flagellomere subcubic (Fig. 78). - Head in dorsal view (Fig. 79) twice as broad as long, eye one-third longer than temple, latter constricted, occiput excavated (Fig. 79). Eye in lateral view 1.6 times as high as wide, temple beyond eye broadening ventrally and eye onefourth wider than temple. Clypeus 1.75 times as wide as high, its lower margin medially just concave (Fig. 80). Face 1.5 times as wide as high. Malar space twice as long as basal width of mandible. Face arcuate rugo-striolate, sides of frons arcuate striate and with an arcuate carinula, vertex transversely rugulo-striatc (Fig. 79). Mesosoma in lateral view 1.6 times as long as high. Mesonotum with more or less confluent punctation, notaulix distinct and crenulate, hind-median field of mesonotum areolatc-rugose. Scutellum punctulale, interspaces polished. Mesopleuron areolate. Propodeum anteriorly roughly rugose, its declivous posterior part strongly punctate-subpunctale; caudal margin of propodeum defined by a transverse ridge, two pairs of projections weak. - Hind femur 2.9 times as long as broad medially (Fig. 81). Fore wing as long as head, mesosoma and half of carapace combined. Pterostigma (Fig. 82) 2.5 times as long as wide and issuing /-just distally from its middle, r half as long as width of pterostigma and nearly as long as 3-SR, 4-SR straight; marginal cell along 1-R1 almost as long as length of pterostigma. Carapace somewhat shorter than head and mesosoma combined; in dorsal view (Fig. 83) twice as long as broad medially and somewhat pointed apically; in lateral view 2.8 times as long as high behind and 1.6 limes as high behind as basally (Fig. 84, see arrows within carapace). Carapace apico-laterally truncate (Fig. 84, see arrow outside carapace), apico-ventrally just incurved (Fig. 85, see arrow). Carapace strio-rugose (Fig. 83), apically rugose; apically with a very small elliptic foramen (Fig. 86). Colour of body as in the original description. Body black. Scape, pedicel and first flagellomere reddish yellow, flagellum progressively darkening. Palpi pale. Tegula reddish yellow as arc legs, hind coxa brown, middle and hind femora + tibiae with brownish tint. Wings subhyaline, pterostigma brown, veins proximo-distally yellow to brownish. Microchelonus townsendi (VIERECK) is nearest to M. paululus (McCOMB) and M. constrictus sp. n., the distinction of the three species is presented at M. constrictus sp. n., p. 187. * * * Acknowledgements - I am much indebted to express my sincere appreciation to Mrs A.
