Cenolia AH Clark, 1916b

Table 1

Type species. Comatula trichoptera Müller, 1846 .

Other included taxa (5). Cenolia amezianeae Messing, 2003 , Cenolia glebosus Rowe, Hoggett, Birtles & Vail, 1986 , Comanthus novaezealandiae AH Clark, 1918b, Comanthus spanoschistum HL Clark, 1916, Comanthus tasmaniae AH Clark, 1918b.

Diagnosis. Mouth excentric in fully developed individuals; up to 41 arms; centrodorsal circular to pentagonal, cirri always present; IBr2 united by synarthry; IIBr and subsequent brachitaxes mostly 4(3+4); first syzygy at 3+4 on all undivided arms; distal intersyzygial interval 4, or 4–6 ( Cenolia amezianeae ); distalmost pinnule comb on P2, or P19 ( C. amezianeae ); comb arising gradually and tapering to a blunt point; teeth paired, equally-sized, confluent and/or forming transverse ridges.

Distribution. Southern and eastern Australia (Trigg I., WA, to Mooloolaba, QLD, including Tasmania), Norfolk I., Lord Howe I., New Zealand, and ( C. amezianeae ) New Caledonia and Vanuatu (AH Clark 1931; Messing 2003; Rowe et al. 1986; Rowe & Gates 1995). Depth range: 0– 310 m.

Remarks. A revision of all current Cenolia species is currently underway (Wilson et al. in prep). Cenolia amezianeae , known from southern New Caledonia and Vanuatu (Messing 2003), is the only tropical Cenolia species, the only one with pinnule combs distal to P2, and is the only Comasterini with a distal intersyzygial interval of 4–6 (rarely 3, 7, 9).
