Chaetozone corona Berkeley & Berkeley, 1941 Chaetozone spinosa corona Berkeley & Berkeley, 1941: 45–46. Chaetozone corona : Hartman 1960: 125; 1961: 109–110; 1969: 235, figs. 1–3; Blake 1996: 285–287, figs. 8.6; Çinar & Ergen 2007: 341–345, figs. 2–4; Dean & Blake 2007: 46–47, fig. 3; Çinar 2009: 2304–2305; Çinar et al . 2011: 2115; Çinar et al . 2012a: 1462; Çinar et al . 2012b: 960; Çinar & Dagli 2013: 925; Blake 2015: Table 2; Le Garrec et al . 2017: 433–445, fig. 3. Material examined . Off Ecuador , SEPBOP, R / V Anton Bruun Cr. 18B, Sta. 768-D, 10 Sep 1966, 03°36ʹS, 80°38ʹW, ca. 50 m (1, USNM 1490770). Descriptive remarks . The single specimen is complete, 16 mm long, 1 mm wide, and with about 60 setigerous segments. The pre-setigerous region is short and thick with a triangular-shaped prostomium and thick peristomium with a rounded dorsal crest. The characteristic eyespots are not visible, possibly having faded after 50 years in preservative. Three neuropodial spines are present from setiger 1; a single notopodial spine is present from setiger 4. Posterior segments contain partial cinctures with three notopodial acicular spines and five neuropodial spines. The spines alternate with capillaries. Long natatory-like capillary setae arise from anterior and middle-body notopodia. Small oocytes are present in the coelom. General remarks . This single specimen is the first record of Chaetozone corona from the SE Pacific off South America. Previous Pacific records are from California to Costa Rica (Blake 1996; Dean & Blake 2007). Other records of the species are from Brazil, the Mediterranean Sea, and the Bay of Biscay; these records are summarized by La Garrec et al. (2017). The widespread occurrence of C. corona outside the Pacific Ocean suggests it may be an introduced species in those sites (Le Garrec et al . 2017). Distribution. Eastern Pacific, California to Ecuador, 24–120 m; Brazil, shallow water; Bay of Biscay, 12–33 m; Mediterrean Sea, 2.5– 90 m. : Published as part of Blake, James A., 2018, Bitentaculate Cirratulidae (Annelida, Polychaeta) collected chiefly during cruises of the R / V Anton Bruun, USNS Eltanin, USCG Glacier, R / V Hero, RVIB Nathaniel B.
