Ursinoscorpaenopsis kitai was first formally described in 1996 by Tetsuji Nakabo and Umeyoshi Yamada and is known only from its type, which was collected in the East China Sea from a depth of 138 m (453 ft).[2] The genus name Ursinoscorpaeanopsis refers to its "bearlike shape" and similar to Scorpaenopsis. The specific name honours the collector of the type Tsugiyoshi Kita of Nagasaki.[3]

The genus Ursinoscorpaenopsis differs from other scorpionfish genera by havinga paranuchal spine, a supplemental spine on the last suborbital spine and non-fleshy, branched fin rays in the pectoral fin rays. It also has an orange-reddish body, lacks any teeth on the palatine, has a swimbladder, and possesses a supraneural and 5 unfused hypurals. This genus appears to be one of the more basal genera in the family Scorpaenidae.[4]
