Description

General features

Fore wing 13 mm long. Nervellus broken near the middle. Mandible with lower tooth longer than upper tooth. Flagellum with 37 segments. Head polished, face and partly clypeus with median longitudinal wrinkles. In dorsal view temples parallel behind eyes. Notauli strong. Mesopleuron, metapleuron, scutellum, mid and hind coxa and hind femur densely and clearly punctate. Metasoma polished, without well defined punctation. OTI 2.3. Hind femur robust.

Female. Head, mesosoma and metasoma black. Coloration of first and second tergites varies (see "Taxon discussion") (Fig. 1a, b, c). Clypeus and mandibles black. Flagellum black with white ring, scape and pedicel black. Legs black: all coxae, trochanters and trochantelli almost black, fore and mid tibiae and tarsi ventrally, apex of fore and mid femora, base of hind femur and tibia and tarsomeres 2-5 of hind tarsus white.

Male. Coloration as in female, but differs by face, tegula entirely andpedicel partly yellow. Flagellum yellow ventrally, without white ring. First and second tergites with wide apical light stripes (Fig. 1d).

Notes

The another European species, Arotes ustulatus   Kriechbaumer, 1894, differs from Arotes albicinctus   Gravenhorst, 1829 in coloration of legs (which are red except coxae) and in the possession of a fuscous spot on the apex of the fore wing.

Taxon discussion

The main distinguishing characters, between Arotes albicinctus   Gravenhorst, 1829 and Arotes annulicornis   Kriechbaumer, 1894, given by various authors are the coloration of the first and second tergites of metasoma, which are entirely black in Arotes annulicornis   Kriechbaumer, 1894 and light-coloured posteriorly in Arotes albicinctus   Gravenhorst, 1829, and pterostigma, which is reddish centrally in Arotes annulicornis   Kriechbaumer, 1894 and entirely fuscous in Arotes albicinctus   Gravenhorst, 1829. Kolarov (1997) and Constantineanu and Pisica (1977) gave another character, the length of ovipositor sheaths, which are slightly shorter than body in Arotes annulicornis   Kriechbaumer, 1894 and as long as the body in Arotes albicinctus   Gravenhorst, 1829.

My examination of the holotype of Arotes annulicornis   Kriechbaumer, 1894, which is deposited at HNHM, demonstrated that the first and the second tergites have light-coloured (though very weak) posterior margins. The three of metioned above females (collected in the same locality) have first and second tergites varies from entirely black to white-striped. The coloration of the pterostigma is also varies in the studied specimens: from yellowish-brown centrally with fuscous margins to entirely fuscous. The ovipositorial sheaths are as long as the body in the specimens with black tergites, so no evident differences between the two species, Arotes annulicornis   Kriechbaumer, 1894 and Arotes albicinctus   Gravenhorst, 1829, may be found. Arotes annulicornis   Kriechbaumer, 1894 is therefore a junior synonym (syn. nov.).
