Tribe Zimmeriini HEINRICH

Zimmerini HEINRICH 1934 - Mitt. Zool. Mus. Berlin: 67 (key).

Type genus: Zimmeria HEINRICH (= Coticheresiarches TELENGA)

Zimmerini : PERKINS 1959 - Roy. Ent. Soc. London 7 (2) (aii): 24, 47.

Zimmeriini : RASNITSYN 1981 - Opr. Faun. SSSR 3 (3): 510.

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:

The representatives of tribe are rather large ichneumon flies with very rough sculpture of head and thorax with the whole set of specific characters. The species of tribe have long, slender flagellum, a head with narrow, long and flat clypeus sharply bent forward from surface of face, unidentate pointed mandibles and two sharp impressions on vertex between lateral ocelli and eyes. Thorax is with extremely rough sculpture with exception of mesonotum, without sternauli, with high elevated and carinated scutellum, propodeum with angular break (of broken type) with sharp, high and rough carinae, large elongated spiracles and strong flattened laterally teeth or apophysises. Abdomen is broad, oval, amblypygous of females. First tergite is with flattened petiolus and long postpetiolus, reminding first tergite of Eurylabus . Gastrocoeli and thyridia are from slightly developed to sharply expressed. Sternites of abdomen are sclerotized, but with longitudinal fold. Ovipositor is straight in contrast to Eurylabini .

M o r p h o l o g y:

F l a g e l l u m: Of females long, slender, bristle-shaped, with weakly separated segments, not widened beyond middle and slightly flattened ventrally. (Of females Coticheresiarches meyeri TELENGA segments dorsally up to middle with flattenned area). Flagellum of males not flattened ventrally without tyloides. Flagellum approximately equal by length to front wing.

H e a d: Head contour from front rounded, strongly narrowed downwards. Vertex from lateral slightly slanting down to occipital carina; between hind ocelli, eyes and occipital carina with sharp broad impressions; mandibles strong, without teeth, smoothly and quite sharply narrowed from base to apex, from above gradually curved; clypeus small, only just wider than length, slightly convex, strongly unbend forward relatively face, with sharp protrude ahead front margin, sharply separated from middle field of face; middle field of face narrow, very high elevated; antennal cavities moderately impressed.

T h o r a x: Epomiae very strong, sharp; pronotal base practically straight. Mesonotum moderately convex, slightly longer than width; notauli absent; surface of mesonotum densely punctured, shining, without microsculpture; mesopleurae at bottom with sharp bend; sternauli absent; scutellum high elevated above postscutellum, with convex horizontal part, laterally carinated. Hind margin of metanotum with broad triangular projections. Propodeum from lateral shortened, with angular break (of broken type); carinae of propodeum sharp, with exception of costulae and coxal carina, wrinkled at horizontal part; basal area short and deep; areae dentiparae at apices with flat apophysises; spiracles large, long. Surface of propodeum, including metapleurae very roughly-wrinkled, slightly shining.

L e g s: Strong. Hind tarsi thickened and compressed from sides, tibiae also compressed with tooth at apex. Claws long, thin, slightly curved, smooth.

W i n g s: Areolet quadrangular, symmetrical; nervulus interstitial or slightly postfurcal; membrane of wing darkened.

A b d o m e n From above broad or slightly longish-oval, amblypygous with blunted apex. First tergite from lateral with distinct bend between petiolus and postpetiolus; petiolus flattened at base, from lateral sharply bordered by carinae, dorsal carinae join with dorsolateral not far from spiracles; postpetiolus broad, long, with expressed wide middle field. Gastrocoeli short, from small to broad, of males deep; thyridia of females slightly expressed, of males sharp, near base of second tergite, from very narrow to equal by breadth to interval between them; lunulae very distinct; surface of abdomen of females without strong rugosity, second tergite of males roughly punctured to wrinkled, apical tergites with superficial punctures. Ovipositor straight, not curved downwards as of Eurylabus ; sternites of abdomen sclerotized, but with longitudinal fold, except hypopygium.

C o l o r a t i o n: Black, or black with red (abdomen); legs red; without white pattern.

S i z e: 11-15 mm.

B i o l o g y:ParasitesofLymantriidae.
