Dendrobaena mahunkai sp. n.

( Figs 1, 2, 5 View Figs 1–5 , 6 View Figs 6–8 , 9 View Figs 9–12 )

Holotype: Z/15238 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/15098 two ex. Locality same as that of the Holotype.

Etymology. The new species is dedicated to Prof. Dr. SÁNDOR MAHUNKA (Budapest) on his seventieth birthday.

Diagnosis. Length: 38–50 mm, diameter: 4–5 mm, setae distant. Pigmentation red-violet. Clitellum on ½ 25–33, tubercles lacking. Male pore on 15 large. Septa 7/8–9/10 thickened. Three pairs of vesicles in 9, 11, 12; spermathecae lacking. Calciferous glands with diverticula in 11, 12. Nephridial bladders “octaedra” type.

Description. Holotype: length 50 mm, diameter just after the clitellum 5 mm. Number of segments 118. Paratypes: 38–46 mm long and 4–5 mm wide. Number of segments 89–108. Colour red-violet, paler on ventral side. Prostomium tanylobous, first dorsal pore at the intersegmental furrow 5/6 ( Figs 1–2 View Figs 1–5 ). Setae distant, setal formula at segment xl: aa:ab:bc:cd:dd = 2.44:1.11:2.22:1:4.4 ( Fig. 6 View Figs 6–8 ). Male pores large on the segment xv covering also the neighboring segments. Nephridial pores irregularly alternated between setal line b -d. Clitellum on segments xxv (xxvi)–xxxiii. Tubercula pubertatis and genital papillae lacking.

Internal characteristics: Septa 6/7, 10/11–11/12 slightly, 7/8–9/10 strongly thickened. Free testes and funnels paired in segments x–xi. Seminal vesicles present in segments ix, xi and xii. Spermathecae lacking. Calciferous diverticula present in segments xi, xii. Hearts appeared in segments vi-xi, extraoesophageal vessel lacking. Nephridial bladders is of “octaedra” type ( Fig. 5 View Figs 1–5 ). Crop in segments xv-xvi, and gizzard in segments xvii-xviii. Typhosolis large, bi-lobed. Longitudinal muscle layer is of pinnate type ( Fig. 9 View Figs 9–12 ).

Remarks. The new species seems to be close to the Levantine D. samarigera ( ROSA, 1893) and D. hauseri ZICSI, 1973 but differs from both in the position of the clitellum. These three species form a homogenous group characterized by a tanylobous head, dark purple-red pigmentation, lack of tubercles and spermathecae.
