Species often confused with {name}
Northern Purple Spotted Gudgeon
Mogurnda mogurnda
Key differences: While very similar in appearance and often confused, M. mogurnda generally has a more northern distribution (northern Queensland, Northern Territory, New Guinea) and subtle differences in fin ray counts and genetic markers. M. adspersa typically has a more pronounced 'hump' behind the head in larger individuals.
Empire Gudgeon
Hypseleotris compressa
Key differences: Empire Gudgeons are generally more slender, have a more pointed snout, and their spots are typically less defined and more scattered, often appearing as small flecks rather than distinct 'purple spots'. Their coloration is also often more silvery or yellowish.
Flathead Gudgeon
Philypnodon grandiceps
Key differences: Flathead Gudgeons have a distinctly flattened head profile and a more elongated, cylindrical body. Their coloration is typically drabber, lacking the vibrant purple spots of M. adspersa.
