28. Pristicerops HEINRICH

Pristicerops HEINRICH 1962 - Synopsis Nearct. Ichn. Stenop.: 786-787.

Type species: Platylabus bakeri DAVIS.

Pristicerops: HEINRICH 1974 - Ann. Zool. Wars. 32 (8): 165.

D i s t r i b u t i o n: Holarctic (Temperate Zone) and Oriental Regions (highland).

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

Representatives of the genus are characterized by the elongated spiracles, absence of the apophysises or distinct teeth, proportionally comparatively large head relatively to other parts of body, complete set carination of propodeum with developed costulae. Gastrocoeli are not deep, with distinct thyridia, considerably narrower than interval. A body is with a reach yellow pattern. A length of flagellum is approximately equal to a body and to front wings length.

M o r p h o l o g y:

F l a g e l l u m: Long and slender, not widened or slightly widened beyond middle and flattened ventrally, gradually attenuated toward apex with white annulus. Flagellum approximately equal by length to front wing and to body length. Flagellum of males without white annulus and with pronounced elongated narrow or longish-oval light-colored tyloides, in front at apical part with slight notches between segments, but not serrate as Pristiceros GRAVENHORST not flattened and not widened beyond middle.

H e a d: Head contour from front narrowed downwards. Temples from above behind eyes sharply roundly narrowed backwards, from lateral almost parallel to hind margin of eye. Occipital carina meeting with hypostomal carina on considerable distance from mandible base, before place of meeting curved anteriad, so, that part of hypostomal carina visible from lateral; mandibles gradually narrowed from base to apex, lower tooth slightly moved inside; clypeus convex, with form character to tribe, with straight front margin and rounded lateral corners; middle field of face only just protrude, narrow; antennal cavities deep, with distinct tooth between antennal fossae; ocellar triangle only just elevated.

T h o r a x: Transverse furrow of pronotum not interrupted by keel; pronotal ridge not thickened; epomiae strong; pronotal base abruptly curved. Mesonotum moderately convex, approximately of equal length and breadth; notauli not developed or only just marked at base; surface of mesonotum densely punctured, without microsculpture; subalarum rather high and thick, not sharpened; sternauli not developed, in form of slight impressions at base; scutellum high elevated above postscutellum, strongly slanted, carinated laterally up to apex. Hind margin of metanotum with triangle projections. Propodeum from lateral gradually slanting backwards, but not shortened; set of carinae complete; area superomedia of equal length and breadth or wider than length; carinae of area dentipara at apex widened, but not forming distinct apophysises or teeth; spiracles elongated, of moderate size. Surface of propodeum wrinkly-punctured, shining.

L e g s: Long and slender, more strong of females.

W i n g s: Areolet quadrangular; nervulus interstitial. Length of front wing only just shorter than body length.

A b d o m e n Abdomen longish-oval; second tergite slightly transverse; ovipositor from above slightly protrude. First tergite from lateral without sharp bend; petiolus flattened at base, laterally carinated by sharp carinae; from above petiolus uniformly broadened to postpetiolus; middle field of postpetiolus slightly elevated, not carinated. Gastrocoeli not deep, rather long; thyridia distinct, narrower than interval; lunulae not big, distinct; tergites 2 and 3 densely punctured. Hypopygium of female from lateral triangle, slightly compressed from sides, without longitudinal fold.

C o l o r a t i o n: Head and thorax with yellow pattern; tergites of abdomen mainly with yellow apical stripes.

S i z e: 7,5-8,5 mm.
