Modern representation about features of morphology and the group’s status, accepted in the article, is developed by G. Heinrich (1967, 1977). Representatives of subtribe have world-wide, mainly holarctic distribution. In Palaearctic Region the species of 16 genera, including described below Achaiusoides nov.gen. are distributed.

Subtribe is characterized by amblypygous abdomen of females in combination with, as rule, indistinct or absent thyridia and usually small or superficial gastrocoeli. Clypeus is always normal. Areolet of front wings is pentagonal, with broad base. Hind coxae of females are without scopa. Middle field of postpetiolus is striated or longitudinallywrinkled, sometimes punctured, when the subsequent tergites have tendency to less rough sculpture than of Ichneumonina. The sternites are with tendency to strong sclerotization, 4th sternite, but sometimes 2nd and 3rd, usually without fold. Hypopygium of males of many genera is with tendency to form projection medially.

Representatives of subtribe are mainly parasites of Noctuidae , depositing eggs in the caterpillars of the hosts. For the species of most of genera of Temperate Zone of Holarctic, the hibernation of females on imaginal stages is characteristic.
