Hydroscapha granulum is the only species belonging to family of Hydroscaphidae from Turkey. In this study, Hydroscapha granulum (Motschulsky 1855) samples belonging to Myxophaga subordo were collected from five different localities and taxonomical characteristics of the specimens were compared with the specimens in literatures. Differences in some taxonomical features were determined and descriptions of the species were revised according to collected specimens. In the description, some important taxonomical characteristics such as V. sternit of males, VI. tergit and VI. sternit of females, which have not mentioned recently published papers, are given for the first time. In addition, H. granulum was recorded for the first time from the provinces of Bursa and Manisa of western Anatolia.
