Type-species: Benama hutsoni Nixon. Orig. desig. 



Until 1965, this genus was placed in the tribe Diospilini, subfamily Helconinae. It was placed 

 in its own subfamily by Capek (1965) on the basis of morphology and biology. Species of Meteo- 

 ridea parasitize larvae of Lepidoptera but pupation takes place within the host pupal case, which 

 is unique among braconid parasites of lepidopterous larvae.

Host records indicate that species in this group are internal parasites of wood-boring coleop- 

 terous larvae.

Genus HELCON Nces 



Helcon Nees, 1814 (1812). Mag. Gesell. Naturf. Freunde Berhn 6: 216. 



Type-species: Helcon tardator Nees. Desig. by Lepeletier and Serville, 1825. There 

 is a question whether Lepeletier and Serville (1825. In Olivier, Encycl. Method. 

 10: 42) actually designated Helcon tardator as the type-species. However, 

 Westwood (1839) also designated tardator as the type-species of Helcon.

 Edyia Cameron, 1905. Straits Branch Roy. Asiat. Soc, Jour. 44: 108. Cameron spelled the 

 generic name Ediya on page 108 and Edyia on page 109 of the above publication, which 

 appeared in July, 1905. In August, 1905 (Ann. and Mag. Nat. Hist. (7) 16: 159) Cameron 

 again described the genus spelHng the name Edyia, which is now the accepted spelling. 

 Type-species: Edyia annulicomis Cameron. Monotypic
