12. Cratolaboides nov.gen.

Type species: Cratolaboides palpalis nov.sp.

D i s t r i b u t i o n: Russia,FarEast,Primorye.

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

Habitually it is similar to genus Cratolabus HEINRICH. Most of characters of genus Cratolabus are present. They are – form and characters of a head, hypertrophied second segment of the maxillary palps, occipital carina meeting with hypostomal carina far from the mandible base, rather sharp lateral furrow at margins of mesonotum, presence of developed teeth on propodeum, morphology of postpetiolus and second tergite of abdomen, curved metatarsus, similar sculpture of body and also almost full coincidence by coloration. By coloration and presence of teeth of propodeum they are similar also to Dentilabus HEINRICH from which there are distinct by small roundish spiracles of propodeum and by morphology of the second tergite of abdomen. At the same time, some characters which characteristic for Cratolabus are hypertrophied. I.e. extraordinary large size of second segment of maxillary palps (it does not meet at any representatives of the tribe Platylabini ) and sharper lateral furrow of mesonotum. From the other side, some of the characters are not characteristic for Cratolabus : propodeum is with strongly elongated area superomedia and atrophied costula, marked only at base, very small only just elongated (roundish) spiracles, considerably more slightly flattened at base petiolus and not flattened abdomen with more strongly pointed hypopygium.

By morphology and coloration, it is extremely similar to genus Pagarenes , spiracles of propodeum of which are also small and roundish, area superomedia only with rudiment of costula, gastrocoeli and thyridia are similar and also sharply narrowed behind eyes temples and not developed notauli. At the same time, at Pagarenes maxillary palps normal, whereas of Cratolaboides second segment of it is extremely hypertrophied. Coxal carina of Pagarenes is expressed up to middle, of Cratolaboides – reduced. Propodeum Pagarenes is shortened with quadrangular area superomedia, whereas of Cratolaboides it is elongated with long area superomedia. Except that for Pagarenes large whitely-yellow apical spots on 2-3rd tergites and fully black forth are marked, whereas of Cratolaboides all tergites of abdomen are with narrow yellow apical bands. The most important character, from our point of view, extraordinary large, swollen second segment of maxillary palps is absent at Pagarenes .

In case of an admission of independent status of the genus, it should be esteemed as occupying an intermediate position between genera Cratolabus and Pagarenes .

M o r p h o l o g y:

F l a g e l l u m: Of female slender, bristle-shaped, slightly widened and flattened ventrally beyond middle and slightly attenuated toward apex, long, appreciably longer than the front wing.

H e a d: Head contour from front rather strongly narrowed downwards; temples from above strongly and roundly narrowed behind eyes. Occipital carina sharp all round, meeting with hypostomal carina far from mandible base; second segment of maxillary palps extraordinary large size, swollen; clypeus strongly convex, transversal, with straight thinned front margin and oblique lateral corners; middle field of face distinct; antennal cavities slightly impressed; ocellar triangle slightly and smoothly elevated.

T h o r a x: Transverse furrow not interrupted by keel; pronotal ridge not swollen; pronotal base gradually rounded with very acute apex. Mesonotum slightly convex, longer than width, laterally bordered by sharp and deep furrow; notauli not developed; surface of mesonotum with dense punctures, without microsculpture; subalarum thin, not sharpened; sternauli slightly and broadly impressed; scutellum from lateral moderately convex and gradually slanting backwards, laterally carinated up to apex. Hind margin of metanotum with sharp projections. Propodeum from lateral long, slightly angleform; fields of propodeum distinct; costulae and coxal carina absent; area superomedia rectangular, elongated, 1,5 times longer than width; areae dentiparae with strong teeth at apex; spiracles small, roundish. Horizontal part of propodeum shining with irregular wrinkles, metapleurae uniformly punctured by big punctures, shining.

L e g s: Long, hind rather strong. W i n g s: Areolet quadrangular, roundly pointed in front, almost symmetrical; stigma narrow, dark; radius slightly sinuous, long; nervulus interstitial. Front wing almost equal to body length.

A b d o m e n:Fromabove broadly-oval, not flattened; apical tergites strongly hidden, ovipositor slightly protrude; second tergite transversal. First tergite from lateral without sharp transform to postpetiolus, laterally carinated, dorsolateral carina merge with dorsomedian carina below middle of petiolus (as of Cyclolabus and Linycus ), from above uniformly broadened to postpetiolus; middle field of postpetiolus slightly elevated; surface of postpetiolus very slightly wrinkled, shining. Gastrocoeli deeply impressed, triangle, short, equal by breadth to interval between them; thyridia distinct; lunulae distinct, small; tergites 2-3 densely punctured, with microsculpture, slightly shining, apical tergites slightly shagreen. Hypopygium pointed with longitudinal fold, compressed from sides.

C o l o r a t i o n: Body with reach yellow-white pattern; abdomen with apical bands on all tergites.

S i z e: Body length: 6-7 mm.
