Superfamily ICHNEUMONOIDEA 611 



Tribe GRAVENHORSTIINI 



Members of this tribe are internal parasites of Lepidoptera, ovipositing into the larvae ana al- 

 ways emerging from the pupae. 



Genus HABRONYX Foerster 



Gauld (1976) recognized four subgenera, three of which are represented by Nearctic species.

 Hist.) Ent., Bui. 33: 31-41.

Habro7iyx Foerster. 1860. Naturh. Ver. Rheinlande, Verb. 17: 147. 



Type-species: Habronyx gravenhorstii Foerster, Monotypic. The type-species is 

 regarded as a synonym of H. heros (Wesmael).

Type-species: Acanthostoma japonicum Kriechbaumer. Monotypic. The type-species

Type-species: Macrostemma elegans Shestakov. Monotypic.

Type-species: For)nosano7nalo7i baibarense Uchida. Monotypic and orig. desig. 



This small subgenus is known from all zoogeographic regions. The "Marginal Index" of the 

 Nearctic species disagrees with Gauld's (1976) definition of the subgenus Habronyx, and Gauld 

 appears to have placed too much emphasis on this character in his key couplet which dif- 

 ferentiates the subgenera Habronyx and Camposcopus.
