Taxonomy and systematics.

H. Aspöck et al. (1991), Haring et al. (2011). Parvoraphidia is markedly differentiated by morphological characters of adults (small size: 5-8,5 mm; short and very dark pterostigma) (Fig. 2f ) and larvae and also by molecular phylogeny. It has emerged as the sister group of Ornatoraphidia + Turcoraphidia , the genus comprises Subilla three closely related species (includingone subspecies), which can be reliably differentiated only by characters of the male genitalia.

Biology and ecology.

The larvae of all species of the genus live in upper layers of soil. Development probably (mainly)one year. Last stage of hibernation: (probably) full-grown larva.

Distribution.

Parvoraphidia is confined to the southern and southwestern parts of the Balkan Peninsula.

Biogeography.

The Subilla three species represent Balkanopontomediterranean faunal elements with low expansivity.
