Etymology. The name refers to the geographic region of the type locality, the Banat region.

Diagnosis. Length 145–171 mm, diameter 6–7 mm, setae distantly stand- ing. Pigmentation greyish. First dorsal pore in 11/12. Clitellum on ½ 29–½ 39, ½ 40, tubercles on 30–½ 39, ½ 40. Male pores on segment 15. Nephridial pores aligned above setal line b. Three pairs of seminal vesicles in 9, 10, 12; sper- mathecae 7 (6–8) pairs in 5/6–11/12 (12/13) in setal line d. Calciferous glands with well-developed diverticula in 10. Hearts in segments 7–11, nephridial bladders ocarina-shaped.

External characters. Holotype 145 mm long and 7 mm wide. Number of segments 184. Paratypes 146–171 mm long and 6–6.5 mm wide. Number of segments 180–223. Pig- mentation greyish. Prostomium epilobous ⅓ closed. First dorsal pore at the intersegmen- tal furrow 11/12. Setae distantly standing. Setal arrangement behind clitellum: aa:ab:bc: cd:dd = 3.38:2.13:1.22:1:5,07. Male pores on segment 15, small. Nephridial pores aligned above setal line b. Clitellum on segments ½ 29–½ 39, ½ 40. Tubercula pubertatis on seg- ments 30–½ 39, ½ 40.

Internal characters. Septa 6/7–8/9 thickened, 12/13–14/15 strongly. Testes and fun- nels paired in segments 10–11, covered by oesophageal testis sacs in segment 10. The dis- sepiments of 10/11 and 11/12 merged together, completely enclosing the male funnels of 11. Three pairs of seminal vesicles in 9, 10, 12. Usually seven (sometimes 6 or 8) pairs of spermathecae in 5/6–11/12 with external openings in setal line d. In some specimens asymmetrically missing from 5/6 or extra pair present in 12/13. Calciferous glands with well-developed diverticula in segment 10. Paired hearts in segments 7–11. with a pair of small extraoesophageal vessels in 12. Nephridial bladders ocarina-shaped. Crop in seg- ments 15–16, and gizzard in segments 17–18. Typhlosolis lamelliform. The cross-section of the longitudinal muscle layer of pinnate type.

Remarks. Morphologically the new species is most close to Oc. aporus Pop, 1989 (cl: ½ 29, 30–40 and t: 30–40), but differs from it with the number of vesicles (3 vs. 4 pairs), spermathecae (7 vs. 6 pairs) and the type of the tes- tic sacs (oesophageal vs. perioesophageal). Oc. banaticus sp. n. is similar to Oc. hemiandrus (Cognetti, 1901) with the lack of vesicles in segment 11, the number of spermathecae and the oesophageal testis sacs, but differs with the clitellar organs (cl: 28–36, 37, t: 28–38, 39). It is close to Oc. velebiticus Mršić, 1991 with its clitellum and tubercles (cl: ½ 29–39, t: 30–39), but differs with the number of vesicles (3 vs. 4 pairs). The tubercles of Oc. complanatus (Dugès, 1828) are quite similar (30–39, 40) but its clitellum is shorter (28, 29–37) and has 4 pairs of vesicles. Oc. vallorus (Baldasseroni, 1920) (cl: 30–39, t: 29, 30–39) and Oc. mimus (Rosa, 1889) (cl: 28, 29–40, 41 t: 28, 29–40, 41) are similar with their clitellar organs, but differ with the number of spermathecae (6 and 6–7 pairs), the number of vesicles (4 pairs) and the periesophageal testis sacs. Oc. pseudocomplanatus (Omodeo, 1962) is very similar to the new species with its tubercles (1/n 29, 30–39, 40) and the aligned nephridiopores, but differs with its shorter clitellum (1/n 29, 30–37, ½38), reddish colour, the perioesophageal testis sacs and the four pairs of vesicles. The distinguishing characters of the similar species are shown in Table 4.
