14. Fileanta CAMERON

Fileanta CAMERON 1901 - Ann. & Mag. Nat. Hist. 7 (7): 525.

Type species ( Fileanta balteata CAMERON ) = radoszkowskii radoszkowskii BERTHOUMIEU.

D i s t r i b u t i o n: South of Palaearctic and mountains of Oriental region.

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

Strongly, almost straightly narrowed downwards and backwards profile of a head, occipital carina, abrupt far before hypostomal carina with impression between occipital carina and high abscissula and narrow, sharpened to apex unidentate mandibles are characteristic to the genus. Propodeum is without apophysises and teeth but with strongly broadened carina, closing area dentipara from backwards at theirs place, with strongly developed, almost cellular sculpture. Legs are slender with very long and narrow hind femora. Middle field of postpetiolus is longitudinally striated. 2nd and 3rd tergites of abdomen are densely punctured by small punctures, dull, sternites 2-5 with longitudinal fold. Flagellum of male is with narrow tyloides. Hypopygium of male is slightly extended, without long process.

M o r p h o l o g y:

F l a g e l l u m: Long, slender, strongly attenuated and pointed toward apex, behind middle not widened; in males with very slightly differentiated segments and with narrow tyloides.

H e a d: Head contour from front almost straightly narrowed downwards and from above backwards, vertex from lateral almost straightly oblique behind ocelli; occipital carina, abrupt far before hypostomal carina with impression between occipital carina and sharp high elevated abscissula; mandibles narrow with sharpened apex, without lower tooth. Middle field of face and frons with rough sculpture, surface of a head shining with long sparse pubescence.

T h o r a x: Mesonotum slightly convex, only just longer than width, laterally behind middle carinated by high carina, notauli not developed; surface of mesonotum densely and roughly punctured, with slight sine; axillary tongue only just marked; mesopleurae at bottom with distinct bend (break); sternauli distinct to behind middle of mesopleurae; scutellum of females from lateral moderately elevated above postscutellum, from above slightly convex, laterally not carinated, of males rounded in profile. Hind margin of metanotum with projections. Propodeum in profile, with angle-shaped break, with complete set of sinuate carinae with exception of indistinct costulae of females and indistinct coxal carina; area superomedia elongated, often narrowed backwards; carinae closing areae dentiparae from behind broadened, particularly at place of apophysises; spiracles long and narrow. Surface of propodeum with rough sculpture, to cellular, shining.

L e g s: Long and slender; hind femora narrow, long. Hind coxae of females without scopa. Claws long and thin.

W i n g s: Areolet pentagonal, symmetrical with narrow base; nervulus slightly postfurcal; stigma narrow.

A b d o m e n Of females amblypygous, apex compressed from sides, apical tergites not retracted. Middle field of postpetiolus distinctly elevated, its surface from longitudinally wrinkly-punctured to sharply longitudinally striated. Gastrocoeli slightly impressed and short, narrower than interval between them with weak but distinct thyridia; surface of 2nd and 3rd tergites very densely punctured by small punctures, dull, apical part of third and other tergites shining. Sternites 2-5 with longitudinal fold; hypopygium of females rather compressed and triangle from sides with pubescence but without fascicle of hairs at apex, in males distinctly extended and rounded at central part with slightly cut apex.

C o l o r a t i o n: Abdomen of females red on the larger part, second tergite with broad black band at apex. Body of males with rich yellow (not red) pattern, abdomen with black apical bands on tergites 2-3.

S i z e: Body length 13-13,5 mm.
