D i s c u s s i o n:

Sexual dimorphism in the tribe Joppoctyptini is not so radically expressed as for example in the tribe Ichneumonini (Ichneumonina) . Therefore, we found it quite justified to perform the description of new taxa using for description only the male samples.

Genus has the basic signs, that indicate its affiliation with the tribe Joppocryptini . And thus, it is the second genus of the tribe in the Holarctic region.

First of all, it is the typical sickle-shaped mandibles with developed sharp upper tooth and reduced, moved inside lower one. Clypeus is somewhat different in form both from Eccoptosage KRIECHBAUMER and from Holarctic Pseudoplatylabus SMITS van BURGST. However , the shape of clypeus corresponds to the main features of the tribe. It is slightly separated from the face, but slightly impressed to the apex, but nevertheless impressed, although it is not flattened toward the apex to the same extent as in most members of the tribe. Middle field of face is slightly elevated and indistinctly differentiated as well.

Flagellum of males of the genus being described, as well as of males of Pseudoplatylabus is nodose with transverse, bristle-topped carinae. Surface of mesonotum is dull as it is characteristic for representatives of the tribe, with characteristic granulated structure between punctures. Granulated sculpture is developed to a varying degree and on other parts of the body. Surface of a head between punctures is granulated, but not dull as on mesonotum, shining. Scutellum, like in all representatives of Joppocryptini is highly elevated and bordered by carinae laterally. Propodeum is with complete set of carinae, of broken type, although considerably slanted backwards. Further evidence in favor of tribal affiliation of the genus is the morphology of the first and second tergites of abdomen. The shape of the first tergite is similar to shape of representatives of Pseudoplatylabus SMITS van BURGST and Eccoptosage KRIECHBAUMER. First tergite is practically not sculptured laterally and not bordered by carinae and almost straight from lateral. Middle field of postpetiolus is convex, smooth, not bordered. Second tergite is with developed gastrocoeli and distinct almost not oblique thyridia, that are considerably wider then interval between them.

D i s t r i b u t i o n: Russian Far East.

M o r p h o l o g y:

M a l e s

F l a g e l l u m: Bristle-shaped, ribbed up to apex, not widened behind middle.

H e a d: Head contour from front narrowed downwards and from above behind eyes backwards, vertex from ocelli sharply slanted down to occipital carina; malar space very short; mandibles sickle-shaped, curved in middle, with sharp upper tooth and reduced lower one, moved inside and situated with the same plane with upper tooth; clypeus convex at base and slightly impressed to apex (but not flattened sharply as at Pseudoplatylabus with strong impression along front margin and elevated lateral margins), with emarginate front margin, very slightly separated from slightly differentiated middle field of face, bordered along front margin; antennal cavities small, not separated dorsally by distinct border. Face with granulated surface sculptures between punctures, shining, surface of temples polished.

T h o r a x: Mesonotum moderately convex; notauli narrow, distinct almost up to middle of mesonotum; surface of mesonotum with granulated sculpture between punctures, dull; sternauli weak or absent; scutellum high elevated above postscutellum, bordered laterally up to apex by sharp carinae, with convex horizontal part and with granulated sculpture between punctures, its surface from dull to smooth, shining. Propodeum from lateral of broken type with convex horizontal part, without apophysyses but with broadened carinae at theirs place and full set of carinae; area basalis with knoll.
