Fitzingeria annectens – Zicsi & Pop 1984: 246.
Description
External characters: Length 32–55 mm, diameter 3 – 4.5 mm. Number of segments 101 – 116. Pigmentation dark red-violet. Prostomium epilobous ½ closed. Dorsal pores not visible. Setae distantly standing. Setal arrangement behind clitellum: aa: ab: bc: cd: dd = 1.39:1.22:1.67:1:1.44. Male pores minute on one of the segments 22–27. Nephridial pores aligned above setal line b. Clitellum on segments 25–½30, 30. Tubercula pubertatis on 26–28. Glandular tumescence on segments 9 b, 10, 11 c. 12 b.
Internal characters: No dissepiments notably thickened. Testes and funnels paired in segments 10–11, covered by oesophageal testis sac in segment 10 and 11. Four pairs of seminal vesicles in 9–12, 10 and 11 small. Two pairs of spermathecae in 9/10, 10/11 with external openings in setal line d. Calciferous glands with well-developed diverticula in segment 11. The last pair of hearts in 11, with a pair of extraesophageal vessels in 12. Nephridial bladders are biscuit-shaped. Crop in segments 15–16, and gizzard in segments 17–18. Typhlosolis simple, large. The cross section of the longitudinal muscle layer of pinnate type.

Remarks: Dendrobaena annectens was first described as a variety of ganglbaueri until Pop (1949) synonymized both with D. byblica. Zicsi & Pop (1984) examining extensive material from the Southern Carpathians and a syntype housed in Michaelsen’s Collection (Hamburg) recognized that the male pores of this species are shifted backward to the beginning of the clitellum, therefore they removed it from the synonymy of D. byblica and placed it in Fiztingeria. However, Fitzingeria has proven to be polyphyletic. Therefore, we here place all previous Fitzingeria species including annectens in Dendrobaena.
