1. Ponomarenkoa ellenbergeri Olmi, Xu & He , sp. nov.

( Plate 137A–C )

Description of male ( Plate 137A–C ). Fully winged; length 2.7-2.8 mm (holotype 2.7 mm). Fore wing shorter than mesosoma + metasoma. Length of mesosoma + metasoma: 2.4 mm. Colour brown. Antenna 10-segmented, filiform, about five times as long as head (55:11). Antennal hairs very short, much shorter than breadth of antennal segments. Antennal segments in following proportions: 6:5:6:6:6:6:5:5.5:5:7 (holotype); 5:5.5:6:5:5:6:6:6:5.5:7 (paratype). Head shiny, smooth, apparently unsculptured. Clypeus not visible. Mandible with teeth not completely visible, one of teeth very long and sharp. Eye normally protruding, apparently bare. Occipital carina complete. Temple distinct, very short. POL = 3; OL = 2; OOL = 5; OPL = 3; TL = 1; greatest breadth of posterior ocelli: 2; frontal line not visible. Propleura very long, forming a neck between head and pronotum, deeply inserted in occiput. Pronotum short, much shorter than head (3:18) and scutum (3:14); pronotal tubercle reaching tegula. Scutum apparently bare, apparently unsculptured. Notauli complete, posteriorly separated; minimum distance between notauli approximately as long as greatest breadth of posterior ocelli. Scutellum apparently unsculptured, shorter than scutum (8:14). Metanotum shorter than scutellum (3:8), apparently unsculptured. Shape of pronotum, scutum, scutellum and metanotum similar to that of extant males of Dryinidae . Propodeum not clearly distinct, apparently rugose. Fore wing hyaline, without dark transverse bands, with normal venation of extant Dryinidae , with three basal cells (costal, median, submedian) clearly enclosed by pigmented veins. Pterostigma narrow, much longer than broad (15:3); marginal cell closed; distal part of stigmal vein much longer than proximal part (21:9); distal part of stigmal vein not S-shaped; shape of fore wing similar to that of extant Dryinidae . Petiole distinct, much shorter than propodeum (4:10). Shape, length and breadth of wings similar to those of extant Dryinidae . Shape and morphology of body similar to those of extant Dryinidae . Foreleg segments in following proportions: 10 (coxa): 7 (trochanter): 14 (femur): 10 (tibia): 10 (tarsal segment 1): 9 (remaining tarsal segments). Midleg segments in following proportions: 7 (coxa): 4 (trochanter): 16 (femur): 12 (tibia): 20 (tarsus. Hindleg segments in following proportions: 12 (coxa): 5 (trochanter): 20 (femur): 20 (tibia): 23 (tarsus). Maxillary palpi 6-segmented; labial palpi 3-segmented. Tibial spurs 1, 2, 2.

Female. Unknown.

Material examined. Types: holotype ♂: MYANMAR: specimen in Middle Cretaceous Burmese amber (about 100 mybp). Obtained from a mine situated in Northern Myanmar, Kachin State , Tanai Township , Hukawang Valley , SW of Tanai City . Paratype: same locality label as holotype, 1♂. The type specimens will be deposited in SNMS, though actually they are in JWJC (the buying process is being dealt with) .

Hosts. Unknown.

Distribution. Myanmar (Kachin).

Etymology. This species is named after Mr. Sieghard Ellenberger.

Remarks. According to Grimaldi et al. (2002), on the basis of inclusions, Myanmar amber is from Lower Cenomanian. According to Cruikshank & Ko (2003) this amber is from Upper Albian, based on ammonite/pollen. The new species is quite different from P. polonica Ponomarenko , because of the shape of the stigmal vein. It is regularly curved in P. ellenbergeri ( Plate 137A, B ) and S-shaped in P. polonica ( Plate 138A, B ).
