Lumpenopsis hypochroma (Hubbs & Schultz, 1932) .

Y-Prickleback. To 7.6 cm (2.9 in) SL (Hubbs and Schultz 1932). Known with certainty only from British Columbia (Hastings and Walker 2003). Benthic; depth: 30–100 m (98–328 ft) (Campbell 1989). Moved from genus Allolumpenus to Lumpenopsis by Hastings and Walker (2003). The correct spelling of the specific name in the new combination is hypochroma, to agree with the gender (feminine) of Lumpenopsis (Mecklenburg and Sheiko 2004) .
