( Figs 2, 3 )

Holotype: HNHM/16012 , Albania, Dibër district, Lurë area, Fushë Lurë , small bog beneath the lakes, N41°47.595’ E20°12.308’, 1585 m, 20.05.2010., leg. Z. FEHÉR, D. MURÁNYI, ZS. UJVÁRI . Paratype: HNHM/16013 , locality and date same as that of the holotype .

Etymology: The specific epithet refers to the type locality.

Diagnosis. Length 23–24 mm, diameter 2.5–3 mm, setae distant. Pigmentation red-violet. Dorsal pores lacking. Clitellum on 28–33, tubercles 29–31. Male pore on 15, large. Nephridial pores regularly alternate between b and above d. Three pairs of vesicles in 9, 11, 12; spermathecae 9/10–10/ 11 in d. Calciferous glands with well-developed diverticula in 11, 12. Hearts in segments 7–10, nephridial bladders sausage-shaped.

Description. Holotype: length 24 mm, diameter just after the clitellum 3 mm. Number of segments 104. Paratype: 23 mm long and 2.5 mm wide. Number of segments 102. Colour red-violet, darker anteriorly. Prostomium epilobous. Dorsal pores lacking. Setae distant. Setal formula after the clitellum: aa:ab:bc:cd:dd = 1.33:1:1.42:1.25:2.83 ( Fig. 2 ). Male pore great on 15, between setae b–c, surrounded by a glandular crescent. Nephridial pores regularly alternate between setal line b and above d. Clitellum on segments 28–33. Tubercula pubertatis on segments 29–31 ( Fig. 3 ). Spermatophores ventro-lateral, in the intersegmental furrows 20/21, 22/23 and 24/25.

Internal characteristics: All septa membranous. Testes and funnels free, paired in segments 10–11. Seminal vesicles present in 9, 11 and 12. Spermathecae two pairs, clearly stalked in 9/10, 10/11 with external openings in setal line d. Calciferous glands with well-developed diverticula in 11, 12. Last pair of lateral hearts in segment 10. Nephridial bladders simple, sausage-shaped. Crop in segments 15–16, and gizzard in segments 17–18. Typhosolis simple, lamelliform. Longitudinal muscle layer of pinnate type.

Remarks. The new species belongs into the D. attemsi species group which consists of three species possessing tubercles on 29–31. The differences between these three species and D. luraensis sp. n. are summarized in Table 1.
