Carlsonia perturbator (HEINRICH) (Plate 32)

Linycus perturbator HEINRICH 1971 - Nat. Canad. 98: 1022-1024, Ƌ. Carlsonia perturbator HEINRICH 1973 - Nat. Canad. 100: 462-463, ♀, new comb. M a l e

F l a g e l l u m: Moderately long, gradually attenuated toward apex, with 31 segments and with white annulus on segments (7)8-12, practically without constriction between segments, not flattened ventrally beyond middle; basal segments slightly elongated, first segment approximately 3 times longer than width at apex. Flagellum equal by length to front wing and distinctly shorter than body length, with longish-oval light-colored tyloides on segments 9-15.

H e a d: Head contour from front roundish, slightly roundly narrowed downwards, 1,3 times wider than height; genae very short; head from above strongly transversal, 2,2 times wider than length. Vertex from lateral gradually slanting down to occipital carina; temples convex, from above roundly narrowed behind eyes, long, from lateral slightly longer than longitudinal diameter of eye at middle and slightly narrowed downwards; occipital carina from above gradually roundly impressed, far not reach level of eyes and hind ocelli, meeting with hypostomal carina on mandible base; length of gena shorter than mandible base width; mandibles with small lower tooth, behind base gradually narrowed to apex; clypeus convex with straight (slightly rounded) thinned front margin and rounded lateral corners, separated from face by broad impression; clypeal foveae small, narrow, but deep; labrum not protrude from under clypeus; middle field of face broad, slightly differentiated and elevated above lateral fields, 1,4 times narrower than lateral field in middle; antennal cavities not large, deep, reach borders of eyes and far not reach front ocellus level, without lateral tubercles and with slight tubercle between antennal fossae; ocelli of normal size, diameter of lateral ocellus 1,5 times less than distance from ocellus to eye; ocellar triangle elevated. Clypeus and middle field punctured by big punctures, without microsculpture; frons wrinkly-punctured.

T h o r a x: Collar short, transverse furrow narrow, shallow. Mesonotum strongly convex, only just longer than width, notauli distinct up to middle, sharp in front third; surface densely punctured, strongly shining, without microsculpture; subalarum narrow, but not sharpened; speculum smooth, shining, mesopleural fovea deeply impressed; sternauli deeply impressed up to middle; mesopleurae with dense superficial punctures, shining; scutellum moderately elevated above postscutellum, gradually slanted, laterally carinated, almost to apex, horizontal part convex with sparse superficial punctures. Hind margin of metanotum with long bacilliform projections opposite lateral longitudinal carinae. Propodeum from lateral gradually slanting backwards; horizontal part of propodeum short, 2,5 shorter than length of area posteromedia in middle; all carinae developed, with exception of carina, limiting coxal area; area superomedia transverse, nar- rowed in front, 2,4 times wider than length, costulae beyond middle of area superomedia; areae dentiparae without apophysises, only with small denticles; spiracles of propodeum small, roundish, 1,7-2 times longer than width (equal 0,4 breadth of area spiraculifera at place of spiracle). Surface of propodeum cellular, mesopleurae wrinkled, without microsculpture.

L e g s: Long and thin. Claws long, thin, strongly curved.

W i n g s: Areolet pentagonal, asymmetrical (intercubital veins of equal length, but internal vein of apex shorter than external), narrow in front; stigma narrow, dark; radius short and almost straight; radial cell broad; nervulus interstitial; ramulus only just marked; membrane of wing hyaline, veins dark. Front wing 1,4 times shorter than body length.

A b d o m e n:Fromabove long, elongated, almost parallel sided, second tergite longer than width, apical tergites not hidden, visible from above. Petiolus only slightly wider than height, first tergite from lateral angulate, with sharp passage to postpetiolus and strong lateral carinae, from above gradually transform to broad postpetiolus; middle field of postpetiolus limited by strong carinae, sharply diverging backwards, its surface irregularly-wrinkled, shining. Gastrocoeli long with cellular sculpture; thyridia expressed slightly, but distinct, strongly removed from base of second tergite and very slightly oblique, narrower than interval; lunulae distinct, large, practically not elevated; second tergite almost parallel sided, at front half with cellular (reticulate) structure, from middle to apex densely and roughly punctured; third tergite parallel sided, densely punctured, other tergites with delicate punctures.

C o l o r a t i o n: Head of male black with white (yellowish) internal orbits and spots on vertex and below temples; thorax black with red; yellow: collar and upper margins of pronotum, subalarum and spot at apex of scutellum; mesopleurae and propodeum red; abdomen and legs mainly red; tarsi of all legs white.

S i z e: Body length: 9,5; front wing: 7,2; flagellum: 7,0 mm.
