Ectopius WESMAEL 1859 - Mem. Couronnes Acad. Roy. Sci. Let. Beaux-Art Belgique.: 14.

Type species: Ichneumon rubellus GMELIN.

D i s t r i b u t i o n: Palaearctic.

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

The genus is characterized by rounded head with dull white spot on genae, triangle, strongly sloped backwards propodeum with small roundish spiracles, complete carination and sharply transverse area superomedia. Gastrocoeli are in form of longitudinal oblique groove, thyridia very small, also longitudinal or not expressed.

M o r p h o l o g y:

F l a g e l l u m: Slender, beyond middle practically not widened and not flattened ventrally, without white annulus or only with its traces on one-two segments. Flagellum

scarcely longer than the front wing and shorter than body length. Flagellum of males with narrow tyloides.

H e a d: Head contour from front roundish, temples profile behind eyes from above roundly narrowed behind eyes; hypostomal carina meeting with occipital carina before mandible base; malar space approximately equal to mandible base width; form of mandibles character to Platylabini , gradually narrowed from base to apex; clypeus convex, transversal, with rounded front margin, distinctly separated from face; middle field of face slightly elevated above lateral fields, triangular; antennal cavities small, slightly impressed with distinct tooth between antennal fossae; ocellar triangle slightly differentiated.

T h o r a x: Transverse furrow of pronotum not interrupted by keel; pronotal ridge not thickened, epomiae weak; pronotal base sinuously curved. Mesonotum moderately convex, some wider than length; notauli marked only in front third; surface of mesonotum with sparse delicate punctures, shining; subalarum thin, sharpened; sternauli distinctly impressed in front third; scutellum moderately elevated, from above triangle, laterally carinated; horizontal part convex. Hind margin of metanotum with triangular projections. Propodeum triangle from lateral, strongly slanting backwards, its horizontal part considerably sorter than length of area posteromedia in middle; all fields of propodeum distinctly separated by carinae, area superomedia sharply transversal, hexagonal, narrowed in front, of females to 3 times wider than length in middle, of males considerably wider; costulae behind middle of area superomedia; area dentipara at apex without tooth; spiracles of propodeum small, circular.

L e g s: Moderately slender.

W i n g s: Areolet pentagonal, narrow in front; asymmetrical; radius almost straight, short; nervulus interstitial or slightly postfurcal. Front wing shorter than body length.

A b d o m e n: Abdomen of females from above longish-oval, slightly drop-shaped; second tergite slightly transversal; sheath of ovipositor only just visible protrude behind apex of abdomen. First tergite from lateral practically straight, petiolus distinctly flattened at base, lateral carinae of petiolus sharp; from above petiolus gradually broadened to postpetiolus; middle field of postpetiolus almost not expressed. Gastrocoeli in form of longitudinal oblique groove, thyridia very small, also longitudinal or not expressed, lunulae distinct; abdomen shining, surface of second and third tergites densely punctured by superficial punctures. Hypopygium strongly pointed, from below with longitudinal fold.

C o l o r a t i o n: Body brown-black, genae with dull white spot.
