Abstract

The Black-banded sea snake, Hydrophis nigrocinctus, is a poorly known species first
described in 1803 from a specimen collected from the waters of the Bay of Bengal in the
Sundarbans near Kolkata, India. Since then, it has been further reported from the waters near
the type locality (Kolkata, India) in 1849 and another specimen (recorded as H. walli) was
caught in the Malay Archipelago in 1896. In February 2015, during our field survey in the
Sundarbans in Bangladesh, we obtained a specimen of this species from fisheries bycatch after
over a century, representing the third known specimen. We present morphological data and
provide novel information on the reproductive status of this species based on the new specimen.
