The type locality
With regard to the type locality, Müller & Schlegel (1845: 6) mention only: “The fish in question is very common
in some of the lakes along Doeson River in the southern part of Borneo, especially between 1 and 2 degrees
southern latitude.”
Subsequent authors have translated Doeson River as Barito River. However, Müller (1847: 339), in a
description of his collecting trip in Southern Borneo, gives more detailed information on the names of the river
