calcar THOMSON, E. biroi ERDŐS and E. astragali ERDŐS. The species were regarded as sharing missing frontal fork, oral fossa 2.5-4.5 times as long as malar space, anterior margin of clypeus produced forwards, fore tibia with two longitudinal white stripes, POL (post-ocellar distance) nearly or quite twice OOL (ocello-ocular distance), hind ocelli separated by 1-1.75 times their own major diameter from eyes, fore wing speculum open below, basal vein normally bare, three-segmented male funicle. Corrections to the species group structure were proposed by ASKEW (1992). He proposed to include E. (E.) sylvestris SZELÉNYI in the species group cyanellus because of presence of two hardly discernible stripes on fore tibia and male funicle with 3 segments. Our study of the type series of E. (E.) sylvestris (HNHM) and numerous (about 1000) other specimens of this species led to conclusion, that only about 20% of populations of this species possess two hardly discernible stripes on the fore tibia, while the rest have fore tibiae wholly darkened. Wholly darkened fore tibiae and anterior margin of clypeus produced forwards are characteristic for the costalis species group, where I propose to place this species. The appearance of traces of whitish fore tibial stripes in species normally having fore tibia darkened occurs in some other species of Entedon. The origin of the cyanellus species group, in my opinion, may be hypothesized as derivation from the squamosus species group. The latter group contains some species with lower clypeal margin produced forwards (for instance, African E. (E.) diabolus RASPLUS and some Australian species), but they differ from the representatives of the cyanellus species group in having propodeum with spiracular lateral groove and supracoxal groove fused into one complete lateral sulcus (spiracular-supracoxal groove), submedian areas smooth and convex, and hyaline trochanters. In my opinion, the closely related costalis species group might derive from the species group cyanellus resulting from the darkening of fore tibial stripes. Variation of expression of fore tibial stripes in E. (E.) sylvestris SZELÉNYI indicates that this species may be intermediate between the cyanellus and the costalis species groups, but better placed in the latter group. Specimens of E. (E.) sylvestris with hardly discernible light stripes on fore tibiae can be distinguished from the similarly coloured E. (E.) cyanellus DALMAN mainly by strongly produced anterior margin of clypeus is produced (slightly produced in E. (E.) sylvestris). SPECIES GROUP CYANELLUS (GRAHAM 1963, 1971, ASKEW 1992, GUMOVSKY 1997, with additions) Diagnosis. This group is characterized by the following essential apomorphies: fore tibia with two longitudinal white stripes, frontal fork absent, anterior margin of clypeus distinctly produced forwards, propodeum without true (complete, margined at both sides) lateral sulcus. Description. Both sexes: fore tibia with two white stripes, trochanters darkened. Frontal fork absent, sometimes its traces hardly visible among meshes of reticulation E. (E.) marusiki sp.n.). Ve-
