Abstract

Phylogenetic relationships among four genera and 25 species of the tribe Praini (Braconidae: Aphidiinae) were investigated on the basis of 15 characters (13 morphological and two life history characters) using parsimony analysis. Areopraon Mackauer and Pseudopraon Starý are basal within the tribe. Both genera include species in which the external and internal types of pupation exist simultaneously [for example, Pseudopraon mindariphagum Starý, Areopraon lepelleyi (Waterston) and A. pilosum Mackauer)]. It can therefore be asserted that the external type of pupation behavior in the Praini probably originated in the polymorphic pupation behavior of ancient genera such as Pseudopraon and Areopraon. The genera Areopraon, Pseudopraon, and Dyscritulus Hincks form a monophylum separate from Praon. Areopraon is not retrieved as monophyletic. Species of the genus Praon Haliday possess conical apical spines on the top of the ovipositor sheath as an apomorphic character state. Within the genus Praon, we recognized the following closely related species groups: Parapraon + Praon dorsale-yomenae; and Praon rosaecola. Two Praini species are redescribed. Mesopraon Starý is a new synonym of Areopraon. Areopraon silvestre (Starý) and Areopraon helleni (Starý) are new combinations. A key to the recent Praini genera is given.
