♀. Abdomen with eight dorsal segments, the apex rather bluntly pointed. Antennæ longish, not distinctly involute; the joints of the flagellum twice longer than broad; the apical slightly compressed and dilated. Upper tooth of mandibles much larger than lower. Clypeus separated from the face. Head largely developed and obliquely narrowed behind the eyes; the occiput sharply margined. Labrum projecting. Scutellum large, flat or slightly prominent. Post-scutellum depressed laterally at the base. Median segment distinctly areolated; the apex with an oblique, straight slope, clearly separated at the top from the basal part; the supramedian area large, widely separated from the base of the segment, and reaching to the apex of the slope. Spiracles large, linear.
Ventral keel reaching to the fourth segment; the eighth ventral segment distinct. Areolet five-angled. In the male the ventral keel extends to the apex of the fourth segment; the apical segments bluntly pointed.
The areolet is narrowed at the top; the transverse basal nervure is interstitial; the gastracœli are indistinct; the post-petiole is obliquely raised from the base and apex. The longish antennæ, the obliquely sloped apex of median segment, which is not hollowed in the middle, and the abdomen with eight segments in the female, and with the apex rather bluntly pointed, as in Amblyteles, serve to distinguish this genus from Ichneumon.
