description: Bracon (Bracon) bachtiae Beyarslan sp. n. (Figs 1–8)
Description. Female (holotype) (Fig. 1). Length of body 2.2 mm, antennae 2.0 mm, fore wing 2.3 mm, hind wing 1.8 mm, hind leg 1.9 mm, mesosoma 0.7 mm, metasoma 0.8 mm, ovipositor 0.6 mm.
Head. Transverse, ratios of width: length: height of head = 34: 16: 35 (Fig. 2). Antenna with 24 segments. First flagellomere 4.0 times as long as its width and 1.1 times as long as second flagellomere, all flagellomeres longer than their width and penultimate flagellomere 2 times as long as its width (Fig. 3). Width of the hypoclypeal depression 0.5 times of longitudinal diameter of eye, 2 times as long as length of malar space and almost 3 times as long as basal width of mandible; longitudinal diameter of eye 1.3 times longer than transverse diameter; ratios of height of clypeus: inter-tentorial distance: tenterio-ocular distance = 3: 9: 3; length of maxillary palp 0.7 times the height of head; width of face 1.3 times its height, face rugulose and glabrous; ratios of longitudinal diameter of eye: width of face: width of head= 10: 8: 17; vertex and frons smooth and glabrous with some white setae; transverse diameter of eye 2.2 times as long as temple in dorsal view; ratios of OOL: OD:POL = 10: 3: 4; mandible and temple smooth, shiny; length of malar space 2 times as long as basal width of mandible and 0.35 times longitudinal diameter of eye.
Mesosoma (Fig. 4). Mesosoma approximately 1.3 times longer than height; pronotum and propleuron smooth and glabrous; mesoscutum smooth, glabrous; notauli almost indistinct and with sparce white setae; scutellar sulcus and scutellum smooth glabrous; flange of metapleuron almost undistinct; metanotum smooth, shiny; surface of propodeum smooth and glabrous.
Fore wing (Fig. 5). Pterostigma almost ovoid, length of pterostigma 2.3 times its maximal width, vein 1-SR+M curved; vein cu-a almost interstitial; ratio of r: 3-SR: SR1 = 9: 15: 33; CUlb short, 3-CU1 0.5 times as long as mcu and 2 times as long as CU1b; ratios of 2- SR: 3-SR: r-m: 2-M: 2-SR+M= 13: 16: 7: 26: 3.
Hind wing (Fig. 6). Ratios of cu-a: 1-M: 1r-m: 2-SC+R: SC+R1: M+CU= 5: 32: 5: 3: 18: 14; apex of C+SC+R with one especially thickened bristle.
Hind leg (Fig. 7). Hind coxa smooth and shiny; femur weakly compressed; ratios of femur: tibia: basitarsus: tarsus of hind leg = 28: 38: 13: 35; length of femur, tibia and basitarsus of hind leg 3.5, 8.5 and 3.2 times their maximum width, respectively; outer and inner hind tibial spurs 0.46 and 0.42 times hind basitarsus, respectively. Tibia and tarsus densely setose.
Metasoma (Fig. 8). Oval. Length of first tergite 1.1 times its apical width and smooth; suture between 2nd and 3rd metasomal tergites deep and very slightly sinuate; medial length of second tergite 0.3 times as long as its apical width and as long as medial length of third tergite; all tergites delicately rugulose and glabrous.
Colour. Black. Mandibles, clypeus, palpi, legs, lateral sides of first metasomal segment yellow-red. Wing membrane light brown; pterostigma dark brown and veins brown.
Male: Unknown.
Host: Unknown.
Material examined. Holotype: Female—Kastamonu-Daday-Ballıdaġ-Sarpun, (41° 28' 0N,33° 28' 0E) in an area with Pine forest, Rubus fruticosus, Populus sp., and herbaceous plants 1600 m a.s.l., 29.08.2002, leg. O.Cetin Erdogan.
Diagnosis. The new species is distinguished from the congeneric Bracon (Bracon) chagrinicus Beyarslan, 2002, by the synopsis of the following characters:
1(2) Marginal cell not reduced, access apex of fore wing. Length of first tergite as long as its apical width; length of ovipositor sheath almost as long as metasoma....................................... Bracon (Bracon) bachtiae Beyarslan sp. n.
2(1) Marginal cell reduced, not access apex of fore wing. Length of first tergite 0.5 times its apical width; length of ovipositor sheath 0.4 times metasoma................................................... B. (B.) chagrinicus Beyarslan, 2002
Etymology. The species named in honour of Prof. Dr. Bahtiye Mursaloglu who was a famous mammal scientist of Turkey.
