Dendrobaena omodeoi sp. n.

( Figs 3 View Figs 1–5 , 7 View Figs 6–8 , 10 View Figs 9–12 )

Holotype: Z/15240 Turkey, Hatay Province, near the road between Belen and Antakya, 36°

28’58’’N, 36°14’20’’E, mountain limestone region covered by Mediterranean garrigue with small

Quercus , Asphodelus , Euphorbia , Crataegus , Azalea, Pine etc., leg. T. PAVLÍČEK, 11 April 2006. Paratypes : Z/15095 12 ex. Locality same as that of the Holotype.

Etymology. The new species is dedicated to Prof. Dr. PIETRO OMODEO (Siena), the pioneer of earthworm research in Turkey, prominent taxonomist, and evolutionary biologist. baena mahunkai sp. n., nephridial bladder from the postclitellar region

Diagnosis. Length: 52–70 mm, diameter: 5–6.5 mm, setae widely paired. Pigmentation lacking. Clitellum on 26–33, tubercles on 30–31. Male pore on 15 large. Septa 6/7–9/10 slightly thickened. Two pairs of vesicles in 11, 12 and two pairs of spermathecae in 9/10, 10/11 open in setal line d. Calciferous glands without well detached diverticula in ½10–11. Nephridial bladders are sausage-shaped.

Description. Holotype: length 70 mm, diameter just after the clitellum 6.5 mm. Number of segments 145. Paratypes: 52–65 mm long and 5–6 mm wide. Number of segments 134–140. Colour white, pigmentation lacking. Prostomium epilobous 2/3 open ( Fig. 3 View Figs 1–5 ). First dorsal pore at the intersegmental furrow 5/6. Setae widely paired, setal formula at segment xl: aa:ab:bc:cd:dd = 3:1:1.6:1:5.8 ( Fig. 7 View Figs 6–8 ). Male pores large on the segment xv intruding also to the neighboring segments. Nephridial pores irregularly alternated between setal line b -d. Clitellum on segments xxvi–xxxiii, tubercula pubertatis on xxx–xxxi. Genital papillae on segments 11 abc, 26–28, 33 ab. Genital setae of xi 1.10–1.25 mm long, spear-shaped with 0.80–0.85 mm long longitudinal grooves

Internal characteristics: Septa 6/7–9/10 slightly thickened. Testes enclosed in perioesophageal testis sac in segments x–xi. Two pairs of seminal vesicles present in segments xi and xii. Spermathecae in 9/10, 10/11 open in setal line d. Calciferous glands without well detached diverticula in segments x, xi. Hearts appear in segments vi-xi, with a pair of extraoesophageal vessel in xii. Nephridial bladders are sausage-shaped. Crop in segments xv-xvi, and gizzard in segments xvii-xviii. Typhosolis large, bi-lobed. Longitudinal muscle layer is of transitory type ( Fig. 10 View Figs 9–12 ).

Remarks. The new species, due to the structure of the calciferous glands, nephridial bladders and the circulatory system, show similarity with the “ veneta ” species group and seems to be close to the Levantine D. kervillei (MICHAELSEN, 1910) an unpigmented species as well. But D. omodeoi sp. n. differs from it first of all in the opening of the spermathecae and in the structure of the musculature, which is true fasciculate in D. kervillei ( Fig. 11 View Figs 9–12 ) – as in other members of the “ veneta ” group –, but shows transitory characters in the new species. Furthermore, D. omodeoi differs from D. kervillei in the position of the clitellum (xxvi-xxxiii vs. xxv-xxxiv) and tubercles (xxx-xxxi vs. xxx-½xxxii).
