Drusus malickyi Olah & Vitecek sp. n. Fig. 2

Material examined.

Holotype. 1 male: Albania, Shkoder County, Shkoder District, Prokletije Mts, beech forest with brook above Okol; N42.42258, E19.76127; leg. Puskas 05.IX.2013. Currently deposited in coll. WG, will be deposited in János Oláh Private Collection under national protection of the Hungarian Natural History Museum, Budapest, Hungary (JO).

Type locality.

Albania, Prokletije Mountains.

Diagnosis.

The holotype of the new species is most similar to Drusus macedonicus , but exhibits (1) a sharp mediocaudal protrusion of segment IX; (2) a dorsally straight and rough tip of the intermediate appendage distinctly separated by a proximal indentation (3) a distinctly slender and constricted distal half of the inferior appendage in lateral view. Drusus macedonicus males have a mediocaudal and a ventrocaudal protrusion of segment IX, intermediate appendages with two rough rounded dorsal protrusions but lacking a distinct proximal indentation, and to a lesser degree constricted inferior appendages.

Description.

Adult, holotype. Habitus yellow; sternites and tergites fawn; cephalic and thoracic setal areas pale; cephalic and thoracic setation blond, abdominal setation scarce, blond; legs fawn; haustellum and intersegmental integument pale, whitish; wings yellow with blond setae on veins and the membrane. Male maxillary palp 3-segmented, forewing length 10.9 mm, spur formula 1 –3– 3.

Male genitalia (Fig. 2). Tergite VIII fawn, setae scarce; spinate area in lateral view approximately flat with slight dorsad protrusion in anterior half, in dorsal view suboval; flanked by membraneous, less sclerotized areas. Segment IX in lateral view with sharp medial caudal protrusion, ventrally concave distally; in caudal view wider dorsally than ventrally; with irregular triangular, rounded lateral protrusion in dorsal half (best seen in dorsal and ventral views). Superior appendages in lateral view suboval, curved obtusely caudad in proximal quarter, proximally with slight dorsal and distinct ventral protrusions, longest in anterioposterior axis: approximately 2.5 times longer than high; in dorsal view proximally concave medially; medial transverse section oval. Intermediate appendages in lateral view with subtriangular, dorsally rough tip; in dorsal view tips separated, wedge-shaped, approximately parallel; in caudal view approximately triangular. Inferior appendages in lateral view subtriangular, proximally somewhat bulbous, distally slender and distinctly constricted; in ventral and dorsal views with small medial protrusion and slight notch; in ventral view with longitudinal groove delimiting medial lobe. Parameres simple, in lateral view with 1 tine in distal third.

Female, pupa and fifth instar larva unknown.

Etymology.

Named after Hans Malicky, trichopterologist.

Distribution.

Micro-endemic of the Prokletije Mountains, Hellenic Western Balkans (ecoregion 6) (Fig. 11).
