Figs 6a-f Alabagrus species, a, xolotl, lateral mesosoma; b, stigma, lateral mesosoma; c, uchuk, lateral mesosoma; d, tripartitus, lateral mesosoma; e, tripartitus, dorsal propodeum; f, erythromelas, dorsal propodeum. and posteriorly. This is the hypothesized plesiomorphic state; it is the most widespread condition in the Agathidinae and is common throughout the Braconidae. The areola is sometimes reduced or completely absent in members of Alabagrus (Fig. 8c). Species of Pharpa have a rather weak median areola, though the lateral margins are clearly present. Sternaulus (Figs 5a, c-f) The sternaulus is present and foveolate in many ichneumonoids including most Agathidinae. The sternaulus varies from being absent to complete, extending from the posterior border of the mesopleuron to the epicnemium (Fig. If). Most agathidines, including Pharpa, have a sternaulus intermediate in length, usually about 0-5 x the length of the mesopleuron (Fig. 5c). Consequently, this state is considered plesiomorphic for Alabagrus. Longitudinal carinae between metepimeron and metepisternum (Figs 4a-f, 5d) The presence of these carinae is plesiomorphic for Alabagrus; they are present in Pharpa and in most agathidine genera. In Alabagrus, they may be reduced (Fig. 5d) or absent (Fig. 4f)..
