Bluebanded Ronquil . To 27.7 cm ( 10.9 in ) TL (Toby Carpenter, pers. comm. to M.L.). Point Conception, California to Santo Tomás anchorage ( 31°33’N , 116°24’W ), northern Baja California ( Stevenson and Matarese 2005 ). Previous reports from San Francisco and farther north are probably due to confusion with Ronquilus alleni Gilbert, 1904 , and perhaps Ronquilus jordani (Gilbert, 1889) ( Stevenson and Matarese 2005 ) . Benthic; depth 3–178 m ( 9–584 ft ) (min.: Kiernan 1990 ; max.: Gallo et al. 2020b ). Evidently this is the “deepwater ronquil” of Eschmeyer and Herald (1983) ( Stevenson and Matarese 2005 ). Common name, Bluebanded Ronquil, is from Nelson et al. (2004); previously called Smooth Ronquil (Robins et al. 1980). Although Stripefin Ronquil was a name in general use for this species ( Fitch and Lavenberg 1975 , Eschmeyer and Herald 1983 ), R. alleni is actually the stripefin form ( Kiernan 1990 ).
