14. Clypeolabus HEINRICH

Clypeolabus HEINRICH 1974 - Ann. Zool. Wars. 32 (8): 140-141.

Type species: Clypeolabus lamellatus HEINRICH.

D i s t r i b u t i o n: Oriental Region. 2 species from Burma.

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

It is different from other genera by morphology of slightly convex in middle clypeus, without lateral corners and straight front margin, forming in front uniform arch from base to base of mandible and slightly separated from face. Occipital carina does not conjugate

with hypostomal carina, abrupt before them. Hypostomal carina before mandible base is strongly (lamellate) broadened.

M o r p h o l o g y:

F l a g e l l u m: Of female bristle-shaped, slender and long, beyond middle slightly widened and flattened ventrally, with white semiannulus. Flagellum equal by length to front wing. Flagellum of males with distinct longish-oval tyloides.

H e a d: Head contour roundly narrowed downwards with long genae, from above transversal; temples from above slightly roundly narrowed behind eyes; occipital carina not meeting with hypostomal carina, abrupt before it; hypostomal carina before mandible base strongly widened (lamelliform); malar space equal to mandible base width; mandibles with form character to tribe, behind base gradually narrowed to apex; clypeus slightly convex at middle, forming in front uniform arch from base to base of mandible, slightly separated from face; middle field of face narrow, very slightly elevated above lateral fields, only just protrude; antennal cavities slightly impressed with strong tooth between antennal fossae; ocellar triangle distinctly elevated. Clypeus and middle field of face very densely and roughly punctured, shining, middle field at top wrinkly-punctured.

T h o r a x: Transverse furrow of pronotum not interrupted by keel; pronotal ridge not thickened; pronotal base gradually uniformly curved. Mesonotum moderately convex, of equal length and breadth, notauli visible only in front third; surface of mesonotum strongly and extremely densely wrinkly-punctured, without microsculpture; subalarum narrow, but not sharpened; sternauli developed up to middle of mesopleurae; scutellum moderately elevated above postscutellum, convex, laterally carinated up to apex. Hind margin of metanotum with bacilliform projections. Propodeum from lateral of broken type, horizontal part of propodeum shorter than area posteromedia in middle; carinae of propodeum developed, with exception of costulae and coxal carinae; area superomedia approximately square or some wider than length; areae dentiparae with short tooth-like projections, apical transverse carina strongly widened; spiracles of propodeum longishoval, of moderate size.

L e g s: Long, hind tarsi of females sometimes shortened and thickened.

W i n g s: Areolet quadrangular; radius very slightly sinuous, long; nervulus interstitial or slightly postfurcal. Front wing almost equal to body length.

A b d o m e n Oval, rather short, flattened dorso-ventrally. Petiolusbroad with strong lateral carinae, gradually transform to slightly widened postpetiolus; middle field of postpetiolus slightly expressed. Gastrocoeli deep, short, considerably wider than interval with large, slightly oblique thyridia; lunulae large; second tergite very densely and roughly punctured. Hypopygium pointed, flat.

C o l o r a t i o n: Head and thorax black with slight yellow pattern. Abdomen redblack, apical tergites with slight light borders.
