Abstract

We document for the first time in Bangaldesh Dario kajal Britz & Kullander, 2013, a little-known miniature badid species originally described from the Jaintia Hills, India. We provide records of 8 specimens from 3 localities, of which, 2 are in the Meghna basin. Our finding also confirms its distribution from the Brahmaputra drainage, about 300 km southwest from the type locality. The genus Dario Kullander & Britz, 2002 was previously unknown from Bangladesh.

Summary

Introduction

The Badidae is a modest family of small freshwater perches consisting of 31 valid species belonging to 2 genera: Badis (Hamilton, 1822) (24 spp.) and Dario Kullander & Britz, 2002 (7 spp.) (Kullander and Britz 2002, Dahanukar et al 2015, Nelson et al 2016, Britz et al 2018, Fricke et al 2018). The discovery of more abstruse Badis chittagongis Kullander & Britz, 2002, on the other hand, arose from the hill streams of the Matamuhuri River drainage of the Chittagong Hill Tracts (Kullander and Britz 2002, Mahalder 2015). This species, later on, appears in no further works and is considered endemic to Bangladesh
