Lumpenopsis was first proposed as a monospecific genus in 1916 by the Russian zoologist Vladimir Soldatov when he described Lumpenopsis pavlenkoi from Peter the Great Bay on the Sea of Japan, which was its only species and which Soldatov also designated as its type species. [1] The genus is placed in the subfamily Opisthocentrinae within the family Stichaeidae by some authorities, [2] while others treat the subfamily as a valid family the Ophistocentridae. [1]
