Taxonomy.

H. Aspöck et al. (1991). O. flavilabris can easily be differentiated from the second species of the genus, O. christianodagmara , by morphological characters (brown pterostigma with yellowish zone along the costa) (Fig. 2g, h View Figure 2 ).

Biology and ecology.

Larvae (Fig. 3a View Figure 3 ) soil-dwelling. Development variable: Pupation may take place already in the second year (i.e. afterone hibernation of the larva) and the last hibernation stage may be the pupa or the prepupa. At least, under experimental conditions with more or less natural temperatures, sometimes full-grown larvae may pupate in winter, sometimes full-grown larvae overwinter and pupate in spring. At any rate, adults always appear in spring. In the field, imagines can be found - depending on the altitude - from IV to VI/VII. The species is thermophilic, but euryoecious and occurs in a great variety of habitats, preferably with light bush vegetation, particularly also in light forests of various kinds and also in macchia habitats in altitudes of 100 to 2200 m. O. flavilabris has repeatedly been found above the timberline.

Records on Mediterranean islands

(Fig. 8b View Figure 8 ). O. flavilabris occurs on the island of Levkas (records at about 100 m asl); it will, however, probably be found also on other Ionian islands and possibly also on islands in the Adriatic Sea. Syntopic Raphidioptera on Levkas: Parvoraphidia microstigma , Phaeostigma (Magnoraphidia) major , Subilla artemis .

Continental distribution.

The distribution of O. flavilabris comprises southern and northwestern parts of the Balkan Peninsula with a gap in large central parts, the whole Apennine Peninsula, eastern and southern parts of Austria, northwestern parts of Hungary, and the southeast of France.

Biogeography.

O. flavilabris represents a polycentric Balkanopontomediterranean-Adriatomediterranean element with moderate expansivity. The populations of the southern Balkan Peninsula show considerable genetic (but not morphological) differences to populations from the Apennine Peninsula and from Central Europe.
