Subtribe Amblytelina (VIERECK)

Amblytelina VIERECK 1918 - Proc. Biol. Soc. Wash. 31: 74.

Type genus: Amblyteles WESMAEL.

Amblytelina : HEINRICH 1977 - Ichn. Florida and Neigb. States 9: 88.

D i s t r i b u t i o n:World-wide.

I n t r o d u c t i o n:

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 longitudinally-wrinkled, sometimes punctured, when the subsequent tergites have tendency to less rough sculpture than of Ichneumoninae . 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.

M o r p h o l o g y:

F l a g e l l u m: Of females, always bristle-shaped, from moderately to very slender and strongly attenuated toward apex. Flagellum of males with more or less distinct tyloides.

H e a d: Genae and temples usually moderately narrowed, sometimes more or less swollen; clypeus always normal, flat, with straight front margin; mandibles usually normal, teeth always in the same plane, sometime subapical tooth very small, rudimentary or fully absent, sometimes mandibles very broad in a form of spade, rarely narrow ( Hybophorellus SCHULZ ).

T h o r a x: Mesonotum usually flat to moderately convex, rarely considerably longer than width; scutellum usually not elevated, or only slightly, rarely strongly elevated above postscutellum, without lateral carinae. Propodeum often with slightly expressed carinae; costulae absent; areae dentiparae often with small projections, sometimes with strong apophysises (as of type genus Amblyteles ).

L e g s: From moderately strong to rather long and slender. Claws smooth. Hind coxae of females without scopa.

W i n g s: Areolet always distinctly pentagonal usually with wide base.

A b d o m e n Of females amblypygous, from broadly-oval to narrow, elongated and strongly conical. Middle field of postpetiolus often striated or longitudinally wrinkled, sometimes punctured. Thyridia indistinct or absent; gastrocoeli comparatively small, only just marked or absent, only of Ctenichneumon usually rather distinctly impressed; tergites of abdomen usually slightly, rarely ( Ctenichneumon THOMSON ) medially roughly sculptured. Hypopygium of males with tendency to long, pointed projection as of Holarctic genus Spilichneumon THOMSON, Triptognathus BERTHOUMIEU and Eutanyacra CAMERON ; sternites have tendency to more strong sclerotization than of other subtribes, therefore fold usually developed only on sternites 2-3, sometimes only on sternite 2, or absent at all.

S i z e: Species from moderately to large size.

B i o l o g y:

Mainly parasites of Noctuidae . Females of Holarctic species are hibernate.
