less conspicuous hairs ; eyes sometimes with inconspicuous pubescence. 

 Antennal flagellum of male with five or six branches .... 4 



4 (3) Females with the three basal tergites of the gaster subequal in length ; head 

 in dorsal view less than twice as broad as its maximum length ; its length 

 in the middle about equal to the distance between the eyes ; propodeum 

 with a complete median carina. Males with antennal flagellum with five 



branches NO TANISUS Walker (p. 41) 



Females with second tergite of gaster extremely short, transversely linear ; 

 head in dorsal view fully twice as broad as its maximum length ; its length 

 in the middle less than the distance between the eyes ; median carina 

 present only at the front of the propodeum, or at least not reaching its hind 

 margin. Males with antennal flagellum with six branches

Two European species were recognized as a result of the revision by Kerrich (in 

 Kerrich & Graham, 1957). 



Key to European Species 

 (Males) 



1 Head, and dorsum of thorax with strong bronze, brassy, or coppery reflections. 

 Fore wing with distinct fuscous markings, a usually broad transverse band across 

 the stigmal vein, often another below the parastigma, the two bands sometimes 

 joined by a curved dark streak. Malar space at least a little more than half the 

 length of an eye. Eyes separated by their own length or even very slightly more 



laticornis Walker (p. 38) 



- Head, and dorsum of thorax dull green to blue-green, with at most faint brassy 

 reflections. Fore wing immaculate or with only a faint transverse fuscous band 

 across the stigmal vein. Malar space slightly less than half, or barely half, the 

 length of an eye. Eyes slightly larger than in laticornis, separated by about 0-9 times 

 their length ........ obscurus Walker (p. 39) 



(Females) 



1 Head, and dorsum of thorax, with strong brassy to coppery reflections. Fore wing 

 with sharply-defined fuscous markings (as in male, q.v.). Gaster 2-7 to 3-1 times 

 as long as broad. Malar space at least very slightly more than half the length of an 

 eye, nearly two thirds in one specimen. Eyes separated by 0-9 to 1 times their 

 own length ......... laticornis Walker (p. 38)
