Distribution.

The species is only known to occur in Austria. So far, its presence is confirmed from few localities, all in the Steiermark - Murtal districts: Häuslberg bei Leoben (type locality), Hinterberg, Kaiserberg and Gulsenberg b. Preg.

All references for Slovenia originate from the first literary source: Carnelutti 1992. Unfortunately, there is no record of the locality where those specimens were found and no evident material in Carnelutti’s collection. The first author found out about one locality where those specimens were probably collected (Mojmir Lasan, personal conversation 2012) and a visit to this locality, in Gozd Martuljek, in 2013 confirmed presence of D. santicensis population there.

Therefore, we exclude for now D. styriaca from the list of Psychidae from Slovenia.

Remarks.

The genital index of males of this species after verification of old and new material from different localities, slightly differs from the previously reported values of 1.06-1.14 in Weidlich (1996); the revised index has lower values from 0.99-1.14.
