“…fluviatilis complex that were designated as S, T, and U [6]. Later, 2 putative species of X and Y were identified in Orissa State, east-central India, based on differences in the second internal transcribed spacer (ITS2) of ribosomal DNA (rDNA) [7]. Comparison of the ITS2 sequence in Iranian specimens from south and southeastern Iran, including Fars, Sistan va Baluchestan, Kerman, Bushehr, and Hormozgan, showed that they were all homologous to the published ITS2 sequences of species Y (presumably species T) from India [5,8].…”
