This is most likely <em>Rathbunella alleni</em>, the Stripefin Ronquil. This has also been called the rough or smooth ronquil, but those names are not used in a paper by Stevenson and Matarese (2005) that describes the species in this genus along the west coast of the US. <em>Rathbunella alleni</em> has museum specimens from San Francisco down to Baja CA. A similar looking congener, R. hypoplecta--the Bluebanded Ronquil--has no museum specimens north of Point Conception near Santa Barbara, CA. Citation: Stevenson, D. E., and A. C. Matarese. 2005. A revision of the North Pacific fish family Bathymasteridae (Perciformes: Zoarcoidei). Proceedings of the Biological Society of Washington 118:367-406.
