BASEODISCUS PUNNETTI ( COE, 1904) View in CoL View at ENA

( FIG. 3I View Figure 3 )

Taeniosoma punnetti Coe, 1904: 173–177 View in CoL , pl. XVI, figs 1–3, pl. XVIII, fig. 6 (California, USA); Coe, 1905: 158, fig. 31 (California, USA); Joubin, 1905: 311 ( Mexico).

Baseodiscus punnetti: Coe, 1940: 262 View in CoL ; Hiebert, 2016: 43 (California, USA).

Material sequenced: Two specimens (DNA vouchers ICHUM 6332, 6333); Santa Barbara, California, USA, collected by S. A. Maslakova and T. C. Hiebert in 2013.

Sequences: From ICHUM 6332 View Materials : LC178601 View Materials , 18S (1797 bp) ; LC178631 View Materials , 28S (2120 bp) ; LC178679 View Materials , 16S (505 bp) ; LC190953 View Materials , COI (658 bp). From ICHUM 6333 View Materials : LC178632 View Materials , 28S (2057 bp) ; LC178680 View Materials , 16S (504 bp) ; LC190954 View Materials , COI (658 bp) .

Description: From a photograph of a specimen that is different from those sequenced but certainly represents the same species, the body is dorsoventrally dark red, posteriorly becoming pale brown ( Fig. 3I View Figure 3 ). Hiebert (2016: 43–44) described, ‘Pale pink to magenta or red body colour, colour is more pale ventrally; head shape orbicular; conspicuous constriction between head and body marked with oblique cephalic furrows; secondary cephalic furrows present; longitudinal cephalic slits absent; pale colour present at head margins is narrow at anterior tip and widens just anterior to constriction between head and body; many ocelli (80–120, total) are present and visible within the pale region of the head; head can withdraw almost completely into body; body is large, fleshy and wrinkly; rounded anteriorly and slightly flattened posteriorly, in cross-section; caudal cirrus absent. Dark brown or black pigment was noted anteriorly and dorsally by Coe (1904), but this has not been observed by us.’

Distribution: From Monterey Bay, California to Mexico ( Coe, 1904, 1905, 1940; Joubin, 1905; Roe et al., 2007; Hiebert, 2016).

R e m a rk s: O r i g i n a l l y d e s c r i b e d f r o m material dredged from 50 fathoms (91 m) depth between San Pedro and Santa Catalina Island , California, USA ( Coe, 1904) .
