Boucek created this subgenus for Dibrachys affinis Masi and his new species 

 D. Mans, designating (1965^ : 30) the latter as type-species. The species differ 

 from those of Dibrachys s. str. in having the left mandible 3-dentate and the right 

 mandible 4-dentate ; the occipital carina is situated low down near the foramen 

 magnum. In addition they have the body more squat, and the appendages less 

 slender, than in Dibrachys s. str.

Biology. Thompson (1958) gives a list of the recorded hosts of affinis, which 

 includes Anilastus ebeninus (Gr.) (Ichneumonidae), Apanteles glomeratus (L.) 

 (Braconidae) ; Diptera Calliphoridae (Calliphora spp.) ; and Lepidoptera of the 

 families Tortricidae, Gelechiidae, Hyponomeutidae, and Oleuthridae. It has also 

 been recorded (Secretariat, etc., 1956 : 119, 126) as a parasite of Stilpnotia salicis 

 (L.) (Lep., Lymantriidae) in Italy. Masi's original material was reared from 

 Eudemis botrana (Schiff.) (Lep., Tortricidae). Adults appear during the summer 

 in western Europe, specimens captured in the field in June, July and September.
