PTEROMALIDAE OF N.W. EUROPE 703 



Polyscelis Ashmead, 1849a : 52 [nee Girard, 1850]. 



Polyscelis Thomson ; Ashmead, 1904 : 319, 321, 386. 



Polyscelis Thomson ; Kurdjumov, 1913 : 4. 



Neopolycelis Hincks, 1944 : 38 [n. n. for Polycelis Thomson nee Ehrenberg]. 



Spaniopus Walker ; Graham, 19566 : 250. 



Spaniopns Walker ; Peck el al., 1964 : 53. 



For a discussion of the generic synonymy, see Graham, 1956& : 250-251. 



There appear to be several European species of Spaniopus, some of them not 

 yet described. My friend Dr. Boucek has captured most of the species and would 

 like to revise the genus ; hence I refer here in detail only to those species already 

 found in north-western Europe, although I include some others in my keys in order 

 that our own species may not be mistaken for them. 



Key to British Species 



(Females) 



i Head in dorsal view (Text-fig. 576) with temples one third as long as eyes, or hardly 

 more. Mid tibia (Text-fig. 579) very slightly expanded and flattened in its distal 

 third. Smaller species, 1-9-2-1 mm. Propodeum without a distinct costula. 

 Fore wing tending to be rather narrow and short, sometimes not reaching beyond 

 the apex of the gaster, immaculate or with a fuscous discal cloud 



dissimilis Walker (p. 705) 



- Head in dorsal view (Text-fig. 575) with temples two fifths to two thirds as long as 



eyes. Mid tibia not at all expanded distally. Larger species, 2-2-3-2 mm. 

 Propodeum usually with a costula more or less indicated, often complete. Fore 

 wing relatively broad, surpassing the apex of the gaster ; usually with a fuscous 

 discal cloud and one or two other clouds beyond it, occasionally with only the 

 discal cloud present, or the wing immaculate . . . polyspilus Graham (p. 706) 



The females of monospilus (Thomson) and amoenus Forster are unknown to me. 



Key to most European Species 

 (Males) 



1 Antennal funicle abnormal : segments 1, 3 and 5 narrower and shorter than the 



other segments, whitish ; segments 2, 4 and 6 annulated with fuscous distally. 

 Mid tibia, on its external edge expanded into a flattened lobe just beyond the 

 middle ........ monospilus (Thomson) (p. 706) 



- Antennal funicle normal, subcylindrical, all its segments of approximately the 



same breadth ; if some of the funicular segments are annulated with fuscous, 

 then the dark ring is situated on the middle of each segment. Mid tibia 

 sometimes not expanded .......... 2 



2 (1) Mid tibia (Text-fig. 577) simple, not expanded, its posterior surface flat. 



Antennal funicle pallid or testaceous, usually having some or all of the 

 segments annulated with fuscous medially. Propodeum often with a distinct 

 costula. Fore wing sometimes with a brownish spot in the middle 



polyspilus Graham (p. 706) 



- Mid tibia (Text-fig. 578) somewhat expanded and flattened distally, its posterior 



surface concave ; tibia pale at base but more or less broadly fuscous to black 

 distally. Propodeum without a costula ....... 3
