Etymology. The genus name refers to Heteropimpla, which shares some remarkable similarities with the new genus. Gender masculine.

Diagnosis. Antenna filiform, with 19 flagellomeres. Notauli strong, joining before scutellum, forming a strong median sulcus reaching hind margin of mesonotum. Fore wing with1-Rs issuing from C+Sc+R far before pterostigmal base; areolet open, with no traces of r-m, 2- Rs slightly longer than 2+3-M, meeting at distinctly obtuse angle; 3-Cu not aligned with 2cu-a. Hind wing with 1-Rs 0.5× as long as r-m, nervellus broken below middle, 2-Cu present. Ovipositor needle-shaped, not serrated, 0.3× as long as fore wing.

Remarks. Unique within Novichneumoninae in having notauli joining before scutellum. Differs from other genera, excluding Heteropimpla, in having 2-Cu in hind wing; from Heteropimpla in having areolet open; from Caloichneumon and Rasnichneumon in having much more flagellomeres.
