Type material. Pteromalus omnivorus Walker. Syntypes, 2 $ and 2 males. 

 One female is pinned and is labelled " Paris reared from Coccinella [sic!] " ; it 

 clearly came from Laporte (Castelnau) who is mentioned by Walker (1835 : 205), 

 but the host cited on the label is incorrect. The other syntypes probably represent 

 the British material referred to by Walker. The specimen which agrees best 

 with the description, a male, is designated LECTOTYPE ; it has been remounted 

 on a card-point, and bears a Waterhouse label " Pteromalus omnivorus Walker ". 



Pteromalus processionae Ratzeburg and P. rotundatus Ratzeburg. Type material 

 presumably destroyed. The former species was synonymized with omnivorus 

 (Walker) by Reinhard (1858 : 18), the latter by Kurdjumov (1913) who also 

 accepted processionae as a synonym of omnivorus.
