100 J. Oláh Diagnosis - This dark species with almost ebony black sclerites belongs to the species complex with large upward arching triangular gonopods and triangular or bilobed cerci inhabiting the Balkan Mountains. Most close to Drusus illyricus sp. n., but differs by having (1) small animal with forewing length of 8 mm, not large animal of 14 mm; (2) posterodorsal spinate area on VIII t h tergite four-lobed in dorsal view, not trilobed; (3) the longitudinal groove of IX t h segment linear, not with ventral arm; (4) cerci with dorsal lobe quadratic, not tapering in lateral view; (5) inner branch of paraproct forming an almost regular quadratic plate in lateral view, not supplied with a dorsal pronounced subapical wart-shaped process. Drusus biguttatus (PlCTET, 1834) - Slovenia: Julian Alp, Radovna stream, 22.VI. 1988, singled, leg. J. OLÁH (17 males, 6 females). Drusus botosaneanui KUMANSKI, 1968 - Albania: Dibër district, Korab Mts, open stream above Fushë Korabit, 1945 m, N4 1 °49.2 15', E20°32.738\ 28.VI.2007, leg. L. DÁNYI, Z. FEHÉR & D. MURÁNYI (2 males, 1 female). Ersekë district, Grammos Mts, Starje, Alikolarë Stream NW of Mt. Qukapeci, 1865 m, N40°21.677\ E20°45.275\ 19.VII.2006, leg. Z. BARINA, G. KIRÁLY , Cs. NÉMETH & D. PIFKÓ (1 male). Skrapar district, Ostrovicë Mts, Backë, stream beneath the pass between Mt. Frengu and Mt. Faqekuq, 1915 m, N40°31.6l4', E20°25.021\ 4.VII.2005, leg. Z. BARINA, D. PLFKÓ & D. SCHMIDT (5 males, 2 females). Drusus dacothracus sp. n. (Figs 56-59) Description - Male (in alcohol). Black species; cephalic and thoracic sclerites dark, black especially on dorsum; appendages including legs brown, haustellum and intersegmental membranous teguments whitish. Spurs of male 1.3.3. Forewing length 11 mm. Male genitalia (Fig. 56). Posterodorsal black spinate area on tergite VIII three-lobed in dorsal view (Fig. 57) and stepped in lateral view; armed with specialized peg-like setae discernible both in lateral and dorsal view; upper spinate lobe narrow in dorsal view; two patches of less pigmented irregularly shaped area of fused setal alveoli located anteriad of black spinate area. Segment IX very long ventrally, very short bridle-like dorsally; its lateral length elongated by rounded triangular lobe anteriad; midlateral sclerotized strips of sternite IX triangular and directed mesad; vestige of sternal lateral suture of fused IX t h segment well-developed without middle fork. X t h segment fused to IX t h tergite forming together short dorsal bridle. Cerci are triangular and bilobed in lateral view; dorsal lobe short triangular; ventral lobe long triangular. Paraproctal complex forming a closed structure around anal opening by inner and outer branches; upward directed slender dorsal apices of inner braches narrow and diverting laterad'both in dorsal and caudal view (Figs 58-59); their upper surface covered with pointed peg-like modified setae similar to surface of posterodorsal spinate area of VIII tergite, exhibiting anchor function during copula; outer Annls hist.-nat.
