Key to European Species 



(Females) 



All the species have the gaster lanceolate, at least as long as the head plus thorax, but usually 

 longer than this. 



1 Pronotal collar not margined, or with at most a trace of a carina visible in 



some lights. Basal cell of fore wing having its distal third or more pilose. 

 Antennae with all funicular segments, except sometimes the first, at least 

 slightly transverse. Ocelli small, the hind ones separated by 2 to 2-5 times 

 their own major diameter from the eyes. Body mainly bronze to coppery 

 bronze ; fore wing infumate, especially discally, sometimes quite strongly 

 so. Anterior margin of clypeus subtruncate. (ANASTIBA sgen. n.) 



geganius (Walker) (p. 565) 

 Pronotal collar with a fine sharp carina throughout, or except just at the 

 sides. Basal cell of fore wing bare or with at most a few isolated hairs. 

 Antennae usually with some of the funicular segments besides the first 

 quadrate or longer than broad. Ocelli larger, the hind ones separated by 

 at most about 1-5 times their own major diameter from the eyes. Body 

 mainly green to blue ; fore wing not infumate, though sometimes with a 

 fuscous cloud below or across the stigma (CECIDOSTIBA s.str.) . . 2 



2 (1) Anterior margin of clypeus quite deeply emarginate, almost incised, medially. 



Fore wing immaculate ; stigma not or only slightly longer than high. 



Body usually bright green to blue-green, occasionally bronze-green . 3 



Anterior margin of clypeus truncate or curved slightly forwards. Fore wing 

 often with a fuscous cloud, proceeding from or lying across the stigma, the 

 latter usually longer than high ........ 4 



3 (2) Propodeum medially only one fifth to one quarter as long as the scutellum ; 



its median area 2-6 to 3-5 times as broad as long . hilaris (Walker) (p. 567) 



Propodeum medially from slightly more than one quarter, to nearly one third, 

 as long as the scutellum ; its median area 2-2 to 2-7 times as broad as long 



adana Askew (p. 568) 



4 (2) Eyes large, separated by their own length or hardly more ; ocelli large, the 



hind ones separated by only about their own major diameter from the eyes. 

 Fore wing with speculum closed or almost closed below ; stigma moderate- 

 sized, separated by 2 to 2-5 times its height from the costal edge of the wing. 

 Combined length of pedicellus and flagellum slightly less than breadth of 

 head. Head and thorax mainly dark blue . . docimus (Walker) (p. 566)
