Аннотация: A phelogeny is proposed for the 30 species groups in the 13 genera here included in the family Pionidae. The phylogeny is based upon a detailed analysis of available morphological data for larval and adult stages according to the methodology advocated by Hennig. The proposed phylogeny provides the basis for a revised classification on the pionids and permits new insight into certain biological manifestations of phylogeny, namely habitat diversification, life history modification, and geographic distribution, in the group.
