Taxonomy.

H. Aspöck et al. (1991). The species belongs to the Ph. notata complex; it can easily be identified by the characters of the genital segments.

Biology and ecology.

Larvae most probably exclusively corticolous, preferably on conifers ( Abies , Pinus ). Development two to Subilla three years. Last hibernation stage: full-grown larva. Adults: V-VI in light coniferous forests.

Records on Mediterranean islands

(Fig. 7b ). Central and southern parts of Euboea in altitudes of 700-1100 m only. Syntopic Raphidioptera : Ornatoraphidia christianodagmara , Phaeostigma (Graecoraphidia) divina retsinata , Ph. (Magnoraphidia) flammi , Ph. (M.) wewalkai , Raphidia (R.) mediterranea .

Biogeography.

Ph. euboica is probably an endemism of Euboea. It represents a monocentric, extremely stationary Balkanopontomediterranean faunal element.
