Dibrachys (Dibrachys) braconidis (Ferriere & Faure) 



Homoporus luniger Nees var. braconidis Ferriere & Faure, 1925 : 226, fig. 1, $. 

 Dibrachys (Dibrachys) braconidis (Ferr. & Faure) Boucek, 1965c : 30. 



Type material. Type female, France, region of Lyon, in BM(NH) as Type 

 Hym. 5. 683. This specimen is very near to the female of boarmiae (Walker) but 

 has the head and thorax more brightly metallic (blue), whilst the head is slightly 

 broader, 2-1 times as broad as long in dorsal view, and 1-3 times as broad as the 

 mesoscutum ; the head and thorax have rather stronger and denser sculpture, and 

 the fore wing has a large yellowish brown cloud below the stigma. Unless these 

 differences are due to geographical variation, it seems likely that braconidis represents 

 a distinct species. It was recognized as a Dibrachys by Novitzky some years ago, 

 and was later recombined into that genus by Boucek (1965c). 



France : region of Lyon, 1923, reared as an external (and often gregarious) 

 parasite of the larvae of Apanteles glomeratus (L.) 



Biology. Original material reared from Apanteles glomeratus (L.), see above ; 

 also recorded as a parasite of Luffia lapidella (Goeze) and L. ferchaultella (Steph.) 

 (Lep., Tinaeidae), Secretariat, etc., i960 : 342, 350.

 Dibrachys maculipennis Szelenyi ; Boucek, 19655 : 30. 



Type material. Syntypes, 15 $ and 7 <$ reared (Dr. Jerniy) from pupae of 

 Hyphantria cunea Drury collected at Adony, Hungary, n-16.viii.1948, presumably 

 in Hungarian Research Institute for Plant Protection, Budapest.

Note. Pteromalus transversus Forster (1841) was referred to Dibrachys by 

 Delucchi (1955a : 174) ; later the same author (1958a : 54) corrected his earlier 

 statement and stated that the type female of transversus was in fact the same as 

 [Dibrachoides] dynastes (Forster).
