Dotoidae

Doto lancei Ev. Marcus and Er. Marcus, 1967 . Dana Point Harbor, California, 1 specimen, 18 November 2017 ( Stacey 2017) to Panama ( Hermosillo 2004).

Previous northernmost locality: Mission Bay , San Diego, California ( Behrens 1991) .

Remarks: Behrens (2004) reported D. lancei from Monterey Bay, but without an image to confirm the identification, we suspect it was actually D. columbiana O’Donoghue, 1921 , which is common in central and northern California and superficially resembles light colored D. lancei but has shorter ceratal tubercles lacking the apical spots characteristic of D. lancei .

Doto form A of Goddard (1996). Woodley Island, Humboldt Bay, Humboldt Co., California, 1 specimen on side of floating dock, 20 May 2016 ( Young 2016) to Punta Rosarito, Baja California (JG, personal observations) and probably Baja California Sur ( Angulo-Campillo 2005 [as D. amyra ]).

Previous northernmost locality: Drake’s Estero, Point Reyes National Seashore ( Goddard 1996).

Additional northern localities: Coleman Beach , Sonoma Co., California, 2 specimens, low rocky intertidal, 26 June 2017 (observed by JG; for image see <https://www.inaturalist.org/ observations/6847120>) .

Remarks: This form is often identified as Doto amyra , but differs from that species in morphology, egg size, mode of development, and genetics (see Goddard et al. 2016, p. 29).
