Genus Urogymnus

Urogymnus granulatus (Figure 11) was reported for the first time from Bangladesh, based on three specimens from one study site. NADH2 sequence analysis from one of the three specimens supported this identification. This confirms that four species of Urogymnus occur in Bangladeshi waters; U. asperrimus, U. granulatus (likely previously misidentified as U. Africana) (Hoq et al. 2011; Roy et al. 2015), U. lobistoma and U. polylepis, especially around mangrove areas in the southwestern region. Urogymnus polylepis (Figure 12) has been recorded in news articles but has not yet been added to checklists. Hence, while this is not considered a new record for Bangladesh, it is the first verified record from 52 specimens.
