Northwest Pacific: only known from the South China Sea at about 380 to 400 km east of Hainan Island Occurrence in the Western Central Pacific uncertain, marginal in the South China Sea (Ref. 11146). For unavailability of material to be examined, the generic placement and recognition of this species is provisional.
