KEY TO THE SPECIES OF LAEVIGATUS-GROUP, 1. Females (After NIXON 1972, considerably modified) 1 (2) First tergite (Fig. 35) virtually hardly widening posteriorly, together with second tergite less sculptured, shiny. Propodeum rather subrugose. Mesonotum shiny with superficial and dense punctation. Hypopygium evenly sclerotized without any lateral creases. Ovipositor sheath short, about length of second joint of hind tarsus. 9cf : 2.5-3.5 mm. An aberrant species of glomeratus­group. — Bulgaria; USSR: European part, Azerbaidzhan, Armenia, Soviet Middle Asia; Mongolia [A. kazak TELENGA, 1949 (!)] 2 (1) First tergite other in shape, either with arched sides (few species, Figs. 39, 43, 53), or with posteriorly widening sides (few species, Figs. 44, 47, 49, 53, 60), or with posteriorly rather converging sides (few species, Figs. 96, 106, 146), or with parallel-subparallel sides (majority of species, Figs. e.g. 71, 83, 100, 117, 120, 125, 133, 152, 158, 163, 185, 194, 201, 202, 214). Ovipositor sheath longer than second joint of hind tarsus, usually about length of hind tibia. Propodeum smooth to eneven, around lunule frequently with rugae, in exceptional cases* entirely rugose. 3 (12) First tergite with arched sides, i.e. narrowing both anteriorly and posteriorly (Figs, 39, 43, 53). 4 (5) Stigma brown or dark brown with a vivid yellow basal spot. Sides of first tergite more or less arched, however, distinctly widening posteriorly (Figs. 29, 53). Antennái joints 17-14 transverse to cubic. Further details see at couplet 25 (24) A. sophiae PAPP 5 (4) Stigma evenly dark. First tergite at most indistinctly widening posteriorly. At most penultimate joint cubic. 6 (7) Both propodeum and hind (or horizontal) half of first tergite medially with a trough. Edge of vannai lobe rather less straight. Species of ater-group in Nearctic Region [A. aristoteliae VIERECK, 1912 (!)] 7 (6) Propodeum and first tergite without any trough. Edge of vannai lobe distinctly convex. 8 (9) Propodeum relatively short, on its posterior half to third rugose, otherwise smooth to uneven (Fig. 38). Body rather stout. First tergite (Fig. 39) subquad­rate, at most 1.3 times longer than its greatest width. Head behind eyes more constricted (Fig. 36). Ovipositor sheath three-quarters as long as hind tibia. Hypopygium tightly infolded along medio-longitudinal line, laterally heavily sclerotized (an aberrant character in laevigatus-grouv)), i.e. without any creases. Hind half of first tergite weakly rugose to rugulose, second tergite with weaker sculpture, third tergite 1.3-1.4 times longer than second one. Two preapical joints of antenna one-and-a-third times longer than wide (9 : 7, 8 : 6, x 100). Inner spur of hind tibia almost as long as half basitarsus, and only somewhat longer than outer one. Mesonotum with distinct and rather shallow puncta­tion, shiny. Scutellum almost smooth. Stigma relatively broad, only twice longer than broad, rí shorter than breadth of stigma (Fig. 37). Spines on hind rim of third tibia rather long and sharply pointed. Wings faintly brownish. Apex of first femur and entire first tibia reddish yellow, second and third tibia dull reddish yellow but gradually becoming infuscate distally. 9 : 3.5 mm. * A. agilla NIXON, A. artissimus PAPP, A. imperátor WILK., A. scaberT<y&.
