P. microstigma can be morphologically differentiated only by characters of the male genitalia, however, the Subilla three species (andone subspecies) of the genus show perfect geographical vicariance. Biology and ecology. Larvae probably exclusively terricolous. Numerous records of adults on low vegetation, bushes and trees in various habitats: light oak and pine forests, on clearings within fir tree forests, on slopes with Genista , on hedgerows at fields in altitudes of 650-1200 m. Development possibly onlyone year. Last hibernation stage: probably full-grown larva. Adults: V-VII. Records on Mediterranean islands (Fig. 7b ). Records so far only on Levkas. It is, however, likely that the species will also be found on other Ionian islands. Syntopic Raphidioptera on Levkas: Ornatoraphidia flavilabris , Phaeostigma (Magnoraphidia) major , Subilla artemis . Continental distribution. Greece north of the gulf of Korinthos, Albania, North Macedonia. Biogeography. Stationary monocentric Balkanopontomediterranean faunal element.
