Type species

Ipodoryctes insignis Granger, 1949   .

Etymology

From combination of the words “Africa” and the generic name “ Ipodoryctes   ”, since members of this subgenus were only recorded in the African continent.

Description ( Figs 16–21 View Fig View Fig View Fig View Fig View Fig View Fig )

HEAD. Head transverse. Ocelli arranged in weakly obtuse triangle with base weakly larger than its sides. Eyes glabrous. Occipital carina incomplete, obliterate below and not joining ventrally with hypostomal carina at short distance. Malar suture absent. Hypoclypeal depression medium size, subround. Postgenal bridge very narrow. Scapus of antenna more or less wide. First flagellar segment subcylindrical, almost straight, not shorter than second segment. Apical segment apically acuminate.

MESOSOMA. Mesosoma not depressed and relatively long. Pronotum dorsally weakly convex, with more or less fine pronotal carina. Mesonotum more or less highly and gently roundly elevated above pronotum; mainly smooth and glabrous. Notauli distinct, almost incomplete, smoothed posteriorly, smooth or partly finely crenulate. Prescutellar depression rather long, with several carinae. Metanotum with short and more or less pointed median tooth (lateral view). Sternaulus (precoxal furrow) rather deep, long, running along anterior 0.6–0.8 of lower part of mesopleuron. Propodeum with basolateral areas and areola distinctly delineated by carinae; lateral tubercles short.

WINGS. Wings not shortened. Pterostigma of fore wing wide. Radial vein of fore wing arising almost from middle of pterostigma. Radial (marginal) cell not shortened. Second radiomedial (submarginal) cell long. Recurrent vein (m-cu) distinctly postfurcal. Nervulus (cu-a) postfurcal. Parallel vein (CU1a) interstitial or not interstitial and arising from anterior 0.3 of distal margin of brachial (subdiscal) cell. Brachial (subdiscal) cell subvertically closed postero-apically before recurrent vein (m-cu) and with antero-posteriorly corner. In hind wing, first abscissa of mediocubital vein (M+CU) 0.4–0.5 times as long as second abscissa (1-M).

LEGS. Hind coxa without or with small basoventral tubercle. Hind femur rather wide, almost without dorsal protuberance. Hind basitarsus 0.7 times as long as second–fifth segments combined.

METASOMA. First tergite not petiolate, rather long and widened toward apex. Second tergite with narrow basal area delineated by rather distinct furrow; with lenticular apical area distinctly delineated anteriorly by deep crenulate furrow and posteriorly by second suture. Second suture deep, complete and regularly curved. Sixth tergite not or weakly enlarged, not longer than previous tergite, smooth, more or less covered following apical segments, posteriorly evenly curved, without emargination. Ovipositor sheath not longer than metasoma.

Diagnosis

This new subgenus differs from Ipodoryctes   s.str. in having the hind coxa without or sometimes with indistinct basoventral tubercle; pro- and mesothorax almost entirely smooth; propodeum with areola delineated by distinct carinae, notauli smooth or almost smooth.
