Trophoniella sp. Brazil

Pherusa sp. – Rullier & Amoureux 1979: 183.

MATERIAL EXAMINED. — Southwestern Atlantic Ocean, Brazil. 2 specimens ( MNHN 884), damaged, many chaetae broken, previously dissected, Rocas Island, R/V Calypso , stn 6, 7- 8 m depth, 17.XI.1961 (12-17 mm long, 1.5-2.0 mm wide, cephalic cage 3.0- 3.5 mm long, 55-57 chaetigers).

DIAGNOSIS. — Tunic with large, white particles dorsally, extended laterally and ventrally, being smaller ventrally and less densely packed posteriorly. Dorsal and parapodial lobes missing. Four or five notochaetae per bundle. First anchylosed neurohooks from chaetiger 5, tips entire. Branchiae pale with a blackish subdistal dot.

DISTRIBUTION. — Only known from the Rocas Island, off Brazil.

REMARKS

As indicated in the key above, this new species is closely allied to T. rigida n. comb. They differ in the relative colour and density of particles, and on the type of neurokooks. Thus, the new species has whitish, very abundant particles and entire neurohooks, whereas T. rigida n. comb. has mostly blackish, sparse particles, and furcated neurohooks. Formal description requires better specimens and should be postponed until they are either collected or made available.
