Very special thanks for the first photo of Acentrogobius vanderloosi to Dr. Gerry R. Allen, from Australia.
The new species is currently known only from the type locality, but probably ranges widely within the Indo-Australian Archipelago (i.e. East Indian region).
The habitat consists of moderately sloped
(about 20 degrees) mud substratum. The slope begins in approximately 1.5 m depth and flattens out at about 18 m.
The first impression is a featureless bottom with very few fishes, but closer inspection reveals numerous burrows occupied by a variety of fishes and invertebrates.
A total of about eight individuals of the new species were observed on the lower section of the slope in 15–18 m depth.
Only widely scattered, solitary individuals were seen, and each was invariably associated with a muddy burrow, into which the fish retreated when approached.
