Molecular and morphological confirmation of Isometrus maculatus (DeGeer, 1778) (Scorpiones: Buthidae) from Northeast India and East Asia.

We present molecular data on Isometrus maculatus (DeGeer, 1778) for the first time from India, Japan, and Taiwan based on the COI gene and justify the cosmopolitan nature of this species. We also address the first population of I. maculatus found in Teliamura, Tripura, India and give its detailed description and comparison with the rest of the Isometrus species from India. Furthermore, we discuss the justification for considering Sri Lanka as the true home of I. maculatus. [ABSTRACT FROM AUTHOR]
