Subtribe Apatetorina HEINRICH

Apatetorina HEINRICH 1968 . Ichn. Stenop. of Africa 1: 50-51.

Type genus: Apatetor SAUSSURE.

D i s t r i b u t i o n: Ethiopian Region and Madagascar. Nearctic (Neotropichneumon HEINRICH 1938).

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

Subtribe Apatetorina is similar by majority of characters with subtribe Protichneumonina , differing by structure of propodeum. Propodeum of representatives of subtribe is more elongated. Area posteromedia is usually from distinctly to many more short than area superomedia and area basalis taken together. Area superomedia usually merged with area basalis, forming long central area, having tendency to protrude in middle to postscutellum and often reached it (adjoin to postscutellum). This central area is often parallel sided, gradually narrowing from base to apex, sometimes widened at place of costulae. It has a tendency to protrude in front in middle or on the whole width towards postscutellum, and from behind, to merging with area posteromedia, forming thus often practically continuous field from postscutellum to apex of propodeum. In contrast to Protichneumonina apex of abdomen of subtribe representatives is as a rule with white spots.

M o r p h o l o g y:

F l a g e l l u m: Of females bristle-shaped, lanceolate, strongly widened and flattened beyond middle. Flagellum of males bristle-shaped, nodose ventrally with narrow tyloides or without tyloides.

H e a d: Head contour from above from moderately to distinctly narrowed behind eyes, sometimes with curved outline. Clypeus slightly convex basally with straight apical margin, usually with slight projection at the middle; mandibles normal, from narrow to strong, apical tooth longer than lower, concavity between teeth from narrow to broad, lower tooth sometimes moved inside ( Apatetorides HEINRICH ).

T h o r a x: Horizontal part of propodeum more elongated, declivous part usually from distinctly to much considerably more short than merged areae superomedia and area basalis; areae dentiparae more gradually slanted downwards to base of hind coxae with tendency to merge apically with areae posteroexternae; area superomedia merged with area basalis and often slightly or not separated from area posteromedia, forming single very long central area, which often parallel sided, gradually narrowed from base to apex, sometimes widened at place of costulae; this central area has tendency protrude in middle in front or on full-width to postscutellum, forming often single continuous area to postscutellum.

L e g s: Quite strong. Scopa on hind coxae of female present (for example of Leptophatnus CAMERON ) or absent.

W i n g s: Areolet quadrangular.

A b d o m e n Abdomen oxypygous. Gastrocoeli from small and shallow ( Apatetor HEINRICH ), small and deep ( Leptophatnus CAMERON ) to big and deep (Coelapatelor HEINRICH). Sheath of ovipositor usually slightly protrude.

C o l o r a t i o n: Basic color of mesonotum more often ferruginous; main colors of abdomen black, brown-red, ferruginous and intermediate colors. Apical tergites of abdomen usually with white spots.
