Diagnosis.
The species may be easily identified according to the key. It differs from any other European species not only in external features (e.g., possessing curiously long lateral setae on the third antennal segment), but also in the structure of male genitalia (
Figs 19–20
): hypandrium with rather short and broad processes ending in a single long seta (not visible on Chvála’s original illustration), two subequally long but differently shaped phallic hooks (right one branched at apex), median extension of postgonites not connecting cranially (ventral apodeme absent), and presence of a sclerotized phallus forming valve-like flat structure.
Distribution.
Mountains of Central and Southern Europe,
Russia
(Amur region).
Remarks.
This species was described from several specimens taken in high European mountains (
2000–2380 m
), viz Rila (
Bulgaria
), Belanské Tatry (
Slovak Republic
), and Wöltzer Tauern (
Austria
). The illustrations in the original description are not clear, including the hypandrium and fore tibia. Details of the phallus are illustrated here for the first time (
Figs 19–20
).
