Paratypes: Z/15099 eight ex. Turkey, Hatay Province, near the road Akbez to Islahiye , 36°52’N, 36°33’E, limestone and alluvial sediments, leg. T. PAVLÍČEK, 16 April 2006 GoogleMaps .

Etymology. The name of this species refers to the Hatay Province, Turkey, from where it was originally found.

Diagnosis. Length: 45–56 mm, diameter: 4–5 mm, setae closely paired. Clitellum on ½25, 25–½39, 39. Tubercles on 34–38. Male pore on 15. Septa 6/7–8/9 thickened. Two pairs of vesicles in 11, 12; two pairs of spermathecae in 9/10, 10/11 open in setal line cd. Calciferous glands with lateral diverticula in 10. Nephridial bladders sigmoid-type, with cephalad bent ental part and an ectal vesiculum.

Description. Holotype: length 54 mm, diameter just after the clitellum 5 mm. Number of segments 160. Paratypes: 45–56 mm long and 4–5 mm wide. Number of segments 169–177. Colour pale, pigmentation lacking. Prostomium epilobous ½ closed ( Fig. 4 View Figs 1–5 ). First dorsal pore at the intersegmental furrow 5/6. Setae strictly paired. Setal formula at segment xl: aa:ab:bc:cd:dd = 16.5:1.5:11:1:35 ( Fig. 8 View Figs 6–8 ). Two pairs of spermathecal pores present in furrows 9/10 and 10/ 11 in the setal line cd. Male pores ventral just above setae b, on the segment xv confined to its own segment. Nephridial pores irregularly alternated between setal line b -d. Clitellum on segments xxiv, xxv–xxxix. Tubercula pubertatis on segments xxxiv–xxxviii. Genital papillae variable usually in the region x–xiii ab and xxix–xxxiii ab. Genital setae of xi 0.600– 625 mm long, spear-shaped with 0.350 –0.375 mm long longitudinal grooves.

Internal characteristics. Septa 6/7–8/9 thickened. Testes and funnels paired in segments x–xi; in x enclosed in perioesophageal testis sacs. Seminal vesicles present in segments xi and xii. Spermathecae in segments ix, x with external openings in the setal line cd. Calciferous diverticula present in segments x with lamellae extending into xi. Paired hearts appeared in segments vi-xi, with a pair of small extraoesophageal vessel in xii. Nephridial bladders sigmoide with cephalad bent ental limb and an ectal vesicle. Crop in segments xv-xvi, and gizzard in segments xvii-xviii. Typhosolis large, tri-lobed. Longitudinal muscle layer is of fasciculate type with strong radial walls ( Fig. 12 View Figs 9–12 ).

Remarks. The new species seems to closely resemble P. bouchei (PEREL, 1977) described from Kazakhstan, but differs from it in the position of the clitellum and tubercles, as well as in the opening of the first dorsal pore.
