CZECH REPUBLIC : BOHEMIA centr., Všenory (6051), 26.vii.1988 , 1 J 1 ♀ , J. Macek lgt., P. Janšta det. ( NMPC ). Description of male. Body length 3.15 mm. Head with upper part of face, vertex and occiput posteriorly partly coppery, lower face bright green, area of scrobal depression with violet tint; thorax dorsally and laterally as well as coxae predominantly bright green with slightly coppery tint, mid and hind coxa apically, fore coxa ventrally, femora, tibiae and tarsi entirely pale to reddish testaceous, last tarsal segments darker apically; tegula reddish testaceous, darkened at apex, venation reddish testaceous; wings slightly fuscous, not hyaline, covered with dark setae; metasoma dorsally in basal part of Gt 1 partly green to dark coppery, followed by a narrow and inconspicuous reddish testaceous band, more distinct in lateral view of gaster, gaster dark coppery with slightly violet reflection distally. Head 1.1 times as wide as thorax and about twice as wide as long. Temples converging, about 0.18 length of head. Head 1.27 as wide as high, mouth 1.8 times as wide as malar space, the latter 0.44 length of eye. Eyes with distinct setae (clearly visible using 50x magnification), 1.4 times as long as wide. Ocelli of medium size: POL: OOL 1.74, OOL: OD 1.6. Sculpture of frontovertex area, best visible between ocelli, slightly rugose with several rather large punctures. Scrobal depression smooth except for a small alutaceous area in the middle. Scrobes slightly projecting laterally up to frontofacial area, producing small but visible protuberance below each lateral ocellus. Vertex covered by dark setae, these pale to whitish on face. Antenna as follows: pedicel plus flagellum 1.4 times length of head, scape slightly extended in the basal part, finely sculptured except for narrow smooth ventral stripe ventrally, reaching to the middle of anterior ocellus, 4.4 times as long as wide. Pedicel 1.7 times as long as high, not as wide as first funicular segment, anellus 2 times as long as wide. Flagellum rather filiform, F 5 and F 6 quadrate, F 7 slightly transverse (ratio of measurements of F 1 -F 7 : 12.5/10.0, 11.5/10.5, 11.5/10.5, 12.0/10.5, 11.0/10.5, 11.0/11.0, 9.5/10.0), clava 3 times as long as wide, without conspicuous micropilosity area ( Fig. 6 ). Figs. 1-6. 1-5 – Eridontomerus cyaneus sp. nov. , female. 1 – head, dorsal view; 2 – antenna, lateral view; 3 – hind femur, anterior view; 4 – forewing, dorsal view; 5 – gaster, dorsal view. 6 – Torymus nemorum Bouček, 1994 , male antenna, lateral view. Thorax densely setose dorsally except for bare area medially on scutellum. Dorsum of thorax coarsely rugulose with piliferous punctures on distal part of mesoscutum and on scutellum. Scutellum slightly convex basally in lateral view, 1.2 times as long as wide, joining mesoscutum at one small point. Propodeum with raised oblong rounded reticulation medially, 3.4 times as wide as long. Hind coxae enlarged and massive, 2.4 times as long as wide and bare dorsally. Forewing densely setose on disc, basal cell dorsally with several setae in upper half and along basal setal line, speculum extended just below parastigma (marginal vein: postmarginal vein: stigmal vein – 48:11:7). Gaster not compressed laterally, dorsally with hind margins of gastral terga straight. Differential diagnosis. In the key by GRAHAM & GIJSWIJT (1998) the male of this species fits the male of an unidentified species ‘T. ?abberant ventralis’ (couplet 47). The male of T. nemorum differs from T. ventralis (Fonscolombe, 1832) in having the scape reaching the middle of anterior ocellus, vertex more distinctly reticulate with several close and quite large punctures, small protuberances below lateral ocelli, thorax dorsally with coarsely rugulose sculpture with piliferous punctures on distal part of mesoscutum and scutellum, propodeum coarsely raised-reticulate and legs reddish testaceous. Bionomics. Unknown ( BOUČEK 1994 ). Distribution. This is probably a rare species, collected so far only in a few localities in the Czech Republic ( Moravia : Lednice (7166), Bohemia : Trabice hill (5350) near Ústí nad Labem ( BOUČEK 1994 ), and Všenory).
