This new goby species inhabits a shallow, slow-flowing brook of the upper Changjiang River atop cobble substrate (male adult shown at type locality in the photo above).  This is a very small species that grows to approximately 30mm (1.1 inch) in length.  Like many tiny reef gobies, this freshwater species packs a lot of power into its diminutive frame.

Rhinogobius maxillivirgatus is described in Zootaxa.
