First evidence of Brachylaima sp. (Diplostomida; Brachylaimidae) infesting the Etruscan shrew (Suncus etruscus) in Iran.

Of the eleven species of shrews described in Iran, the Etruscan shrew (Suncus etruscus), the smallest known extant mammal by mass, is recorded in northern and southern provinces. During rodent control programs, a female S. etruscus was trapped and found naturally infected with a trematode which was morphologically identified as Brachylaima sp. This finding represents the first report of trematodiasis in this host species.
