34. Neeurylabia HEINRICH

Neeurylabia HEINRICH 1967 - Ichn. Stenop. of Africa 2: 423-424.

Type species: Amblyteles spilopterus MORLEY.

D i s t r i b u t i o n: Africa.

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

The type species has a number of the distinct characters. It has distinctly widened and flattened petiolus of Platylabini , characteristic to the tribe morphology of the abdomen and elevated and carinated scutellum. The other structural characters, mainly

form of clypeus and morphology of mandibles, contravene the relationship with Platylabini .

Morphology of the head to a great extent does not correspond to the tribe diagnosis. Clypeus is moderately convex at base with impressed apex and thinned straight front margin. It reminds rather the clypeus of Eurylabus WESMAEL and not corresponds to characters of the tribe. Mandibles are rather strong, narrowed behind base with rather large flat teeth, situated in the same plane. Their form does not correspond to the form character to the tribe.

Femora and tarsi are unusually strong; tarsi of all the legs especially hind are thickened (among Platylabini , legs with similar ratherish morphology, are only in Australian Neolevansa GAULD ).

Gastrocoeli practically not expressed, that also reminds Eurylabini .

In spite of morphology of a clypeus, proportions of a body (ratio of a wings, body and flagellum length) all other characters testify for evidence of belonging to the tribe Platylabini . More over, clypeus somewhat similar of morphology is characteristic also to Central American Abzaria CAMERON possessing also by similar morphology of propodeum with the reduced carinae. It is differed from Spanophatnus CAMERON by the form of clypeus, mandibles and by the sculpture of front tergites of abdomen.

M o r p h o l o g y:

F l a g e l l u m: Of females bristle-shaped, slender, ventrally slightly flattened behind middle, but not widened, with elongated basal segments. Flagellum some longer than front wing and practically equal to body length. Flagellum of males with white annulus, cylindrical segments, not nodose, with long row of unusually long tyloides.

H e a d: Genae and temples swollen; temples from above firstly sharply widened behind eyes, then strongly roundly narrowed; clypeus wide, elevated at base, impressed apically, with thin apical margin, thus rather concave than convex apically; mandibles strong, with form not character to tribe, that even more expressed at males.

T h o r a x: Transverse furrow of pronotum not interrupted by keel; pronotal ridge not swollen; epomiae not expressed; pronotal base with slight break above front coxae. Mesonotum convex, almost of equal length and breadth, strongly punctured; notauli only just marked basally, practically absent; speculum atrophied; scutellum rather short, strongly elevated above postscutellum, strongly convex, densely and roughly punctured, laterally and at apex carinated. Hind margin of metanotum with small projections. Propodeum short, gradually and abruptly slanting backwards almost from base, very densely wrinkly-punctured, with reticulate-rugose slanted part, matt; carinae of propodeum reduced with exception of carinae metapleuralis; spiracles elongated. Surface of metapleurae more rarely punctured, shining between punctures.

L e g s: Femora and tarsi unusually strong.

W i n g s: Areolet quadrangular; membrane of wing hyaline, apices of front wings deeply darkened.

A b d o m e n:Firsttergitedistinctlyflattenedatbase,fromlateralgraduallytransform to postpetiolus without distinct bend; dorsolateral and ventrolateral carinae only just expressed; postpetiolus without expressed middle field; spiracles of postpetiolus far removed from its apex. Gastrocoeli practically not expressed, presented by difficulty recognizable oblique lateral impression, thyridia absent; seventh tergite from above triangle, long. Hypopygium from below flat, triangle, not overlap sheath of ovipositor.

C o l o r a t i o n: Head rusty-red, thorax in considerable extent black, or with predominance of rusty-red coloration, abdomen black with red.

S i z e: Large species: 12-14 mm.
