There is apparently only one (rather variable) species in Europe ; another is known 

 in North America.

Type material. Amblymerus nitescens Walker. One female, LECTOTYPE 

 bearing a Waterhouse label. It has the median carina of the propodeum forked, 

 represented by two straight carinae which diverge from the base of the propodeum 

 and extend to the nucha ; the stigma of the fore wing is a little smaller than in the 

 type of thoracicus. On account of these features I thought at first that the two 

 might represent distinct species (see discussion of variation below). 



Pteromalus thoracicus Walker. Syntypes, 2 $. LECTOTYPE, the first specimen, 

 bearing a Waterhouse label. 



Pteromalus elymus Walker. Syntypes, 4 <$. LECTOTYPE, the second. 



Pteromalus bebryce Walker. Syntypes, 2 <$. LECTOTYPE, a specimen labelled 

 " 38. 8. 13. 68 ", " South of France ", and bearing also a Waterhouse label. The 

 lectotype has the genitalia slightly projecting so that the tip of the gaster appears 

 pointed, whilst the ventral plica is very sharp ; these features cause the gaster to 

 appear rather like that of a female, hence Walker's error regarding the sex. 



Pteromalus euryops Forster. According to Delucchi (1955a : 172) two males 

 stand under this name in Forster's collection (Vienna) ; the specimen which he 

 considered to be the type has a forked median carina on the propodeum [similar 

 to that of the type female of nitescens Walker]. The species was synonymized 

 with thoracicus (Walker) by Boucek (19651? : 8). 



Pteromalus polyphagus Forster. Syntypes, 7 $ in Naturhistorisches Museum, 

 Vienna (Delucchi, 1955a : 171) ; no lectotype has so far been validated.
