The study, published in the international journal Diversity, describes Opsariichthys rubriventris as a unique species endemic to Guangdong and found in the upper reaches of rivers in the Pearl River Basin.

It is reported that the species can be distinguished from its relatives by several characteristics, including 13 to 14 predorsal scales, a lower jaw that protrudes slightly beyond the upper jaw, and cheeks with two mainly longitudinal rows of tubercles. In addition, adult males have a reddish-orange colouration on the lower jaw, belly, pectoral fin and anterior margin of the anal fin.
