Bacciger israelensis Fischthal, 1980 (Trematoda: Fellodistomidae) was recorded from Boops boops (Perciformes: Sparidae) in Bulgarian Black Sea coastal waters for the first time. Re-examination of the morphology of B. israelensis showed some new details: Laurer’s canal opens dorsally a short distance anterior to the excretory pore; seminal receptacle situated posterior to ventral sucker and ventral to ovary; ovary composed of three nearly spherical but not separated lobes forming apexes of isosceles triangle; tegumental spines covering body including entire surface of ventral sucker and distal half of upper part of oral sucker.
