Material examined. Ekar 9 ( EWITA302-15 ): Ekar Mount , Asiago, Vicenza, Italy, 10/11/2014, leg. Maurizio G . Paoletti. Ruio 1 ( EWITA304-15 ), 2 ( EWITA305-15 ): Ruio Vallalta , Follina, Treviso, Italy, 27/04/2013, leg. Maurizio G, Paoletti . Cristoferi 36 ( EWITA058-14 ), 38 ( EWITA060-14 ), 39 ( EWITA061-14 ), 139: Alonte , Vicenza, Italy, 01/02/2014 leg. Federico Gavinelli. ( Altogether seven specimens).

Diagnosis. Medium sized worms, 100–180 mm by 6–10 mm. Colour reddish on dorsum and paler on ventrum. Male pores on 15 or 16 small. Clitellum on 1/n 29, 30–37, ½38; tubercles on 1/n 29, 30–39, 40. Nephridiopores aligned just above b. Two pairs of testes enclosed in perioesophageal testis sacs in 10, 11. Vesicles in 9–12, those in 11 sometimes smaller. Spermathecae seven pairs, in 6/7–12/13.

Remarks. Morphologically this species is close to Oc. complanatus but differs from it in the aligned nephridial pores (irregular in complanatus ), smaller dd setal distance and presence of red-violet pigments. Furthermore, Oc. pseudocomplanatus possesses perioesophageal testis sacs unlike complanatus which has suboesophageal testis sacs.

According to our molecular results, Oc. pseudocomplanatus is not closely related to Oc. complanatus .
