 Ectopoides HEINRICH 1951 - Bonn. Zool. Beitr. 2: 280-281, ♀, Ƌ.   
 Type species: Ectopoides teunisseni HEINRICH 1951 (= brevicornis KRIECHBAUMER 1890).   
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:  
 According to G. HEINRICH (1951) the genus presents itself a connecting link between Ectopius WESM. and Apaeleticus WESM. The most distinct characters, permitting to distinguish it from Apaeleticus are very small and slightly impressed gastrocoeli with thyridia considerably more narrow than interval between them. G. Heinrich indicates also an absence of notauli and sternauli, but for the males from his collection, investigated by us, notauli and sternauli are present, although and developed in considerably less degree than at Apaeleticus. Face and middle field are convex, clypeus and middle field of face are forming from lateral rather uniform arc and clypeus is comparatively slightly separated from face. It is necessary to mark, that similar morphology is observed at males Apaeleticus mesostictus (GRAV.). Abdomen of females, according to Heinrich is not truncated at apex (i.e. apical tergites do not hidden as at species of Apaeleticus). Thus, most distinct characters distinguishing Ectopoides from Apaeleticus are peculiarities of gastrocoeli and thyridia morphology. Contrary to Ectopius propodeum with strong teeth and postpetiolus is strongly and gradually uniformly punctured. Form of males flagellum reminds one of Barichneumon.   
M o r p h o l o g y:  
F l a g e l l u m: Of females short, filiform with white semiannulus. Of males semi bristle-shaped, stout, not flattened ventrally, without traces of white pattern, with longish-oval tyloides on segments 8-16 (17). Flagellum of male longer than the front wing.  
H e a d: Head contour from front roundish, with big eyes and very short genae; temples behind eyes (from above) gradually narrowed backwards and sharply (from side) downwards. Occipital carina meeting with hypostomal carina on mandible base, at place of junction sharply curved forward; mandibles rather short, evenly narrowed from base to apex; clypeus slightly separated from face, at apex with straight impression, transversal, front margin in a form of uniform arch; clypeus and middle field of face protrude on same height, forming from lateral uniform arch; antennal cavities not great but deeply impressed, without tubercle between antennal fossae. Clypeus punctured by big punctures, face and clypeus densely wrinkly-punctured.  
T h o r a x: Transverse furrow of pronotum not interrupted by keel; pronotal ridge not thickened; pronotal base gradually sinuous. Mesonotum moderately convex, some wider than length, notauli of males expressed only in front third; surface of mesonotum densely punctured by big punctures (intervals narrower than punctures); subalarum thin, sharp; sternauli of males expressed only in front third, deep; scutellum convex, from above strongly narrowed backwards, without distinctly expressed lateral carinae. Hind margin of metanotum with long bacilliform projections. Propodeum from lateral with angleshaped contour, horizontal part almost two times shorter than vertical; all areas and carinae of propodeum expressed, carinae sharp, high; spiracles small, roundish; areae dentiparae at apices with distinct teeth. Surface of propodeum largely cellular-wrinkled.  
L e g s: Slender.  
W i n g s: Areolet pentagonal, symmetrical, narrow in front; stigma broad; radius slightly curved, practically straight; nervulus postfurcal. Front wing shorter than body length.  
A b d o m e n From above elongated, second tergite with approximately equal length and breadth at apex; last tergite of abdomen of female hidden, apical tergites of males not hidden. Petiolus at base not wider than height; dorsal and ventral lateral carinae of petiolus sharp; middle field of postpetiolus not or only just expressed, postpetiolus densely punctured by big punctures, shining. Gastrocoeli slightly impressed, long, slanted, thyridia small, only just marked, narrower than interval between them; lunulae distinct, small; second and third tergites densely punctured, shining between punctures, other tergites smooth with sparse shallow punctures.  
C o l o r a t i o n: Body red and black with limited white pattern on head and of male also on mesothorax and coxae. Abdomen red.
