“…The present species is characteristic by having a gradually-tapered and sharply pointed distal end of the spicule, being readily distinguished from most congeners parasitic in murids, which have dull or round distal end or suddenly narrowed near distal end of the spicule (cf. Quentin, 1966;Robles, 2011;Robles et al, 2014;Smales, 2013;Feliu et al, 2000;Ribas et al, 2013). Among the congeners parasitic in murids, only T. petrowi in Arvicola terrestris of Tatarstan, Russia, and T. spalacis in the mole rat, Spalacis microphthalmus, of Ukraine, have been known to have gradually tapered and pointed spicule (Petrov & Potekhina, 1953;Skrjabin et al, 1957).…”
