Male and larva unknown. Differential diagnosis. The new species is most similar to T . iranicum and T . tribulatum . The new species is distinguished from T. iranicum by seta d extending to the posterior border of its tergite (seta d not extending to posterior border of its tergite in T. iranicum ), seta h 1 more than three times longer than seta h2 (seta h 1 less than three times longer than seta h 2 in T. iranicum ) and setae d on femora III and IV extending to tip of related tarsal segments (setae d on femora III and IV never extending to tip of tarsi III and IV). The new species differs from T . tribulatum by setae sc 2 extending to bases of seta c 1 (setae sc 2 not extending to bases of seta c 1 in T. tribulatum ), setae h 1 more than three time longer than e , f and h 2 (setae h 1 less than three time longer than e , f and h 2 in T. tribulatum ), setae h 2, e and f subequal (setae h 2 longer than e and f in T. tribulatum ) and seta d never extending to bases of setae e and f (seta d extending to bases of setae e and f in T. tribulatum ). Type material. Holotype female (TkO-1) found in Orzueeyeh, Baft city, Kerman province, southern Iran , (28° 27’65 N, 56° 12’55 E, altitude 1042 meters a. s. l.), in bottom of a vial containing alcohol and two beetles of Paulusiella sp. ( Coleoptera : Elateridae : Cebrioninae ) collected by Abdolazim Mortazavi, 10 May 2009 . The beetles were collected as a result of attraction to a light trap. FIGURE 1.
