Fauveliopsis cf. challengeriae McIntosh, 1922

Diagnosis.

Specimens complete, 14.5 mm long, 1.5 mm wide at widest point. Body integument rugose and opaque, with scattered small papillae, tapered, posteriorly swollen, with segments in posterior region short (2-4 × wider than long), and 33 chaetigers. Anterior chaetigers with 2-4 chaetae per ramus, capillary and acicular (sigmoid or falcate) chaetae; middle and posterior chaetigers with 2-3 chaetae per notopodium and 3-5 chaetae per neuropodium, including falcate acicular chaetae and capillary chaetae. Interramal papillae distinct, somewhat stalked. Genital papillae not seen. Living in cemented sediment foraminifera tubes.

Remarks.

The type locality for this species is in the Southern Ocean between Antarctica and Australia in 3510 m depth. It has not previously been recorded in Australian waters, but was recently redescribed from specimens from Antarctic waters and Eastern Pacific Ocean ( Salazar-Vallejo et al. 2019b) as the holotype is badly damaged. These specimens from off the east coast of Australia differ from those earlier descriptions in number and types of chaetae along the body. Also, because genital papillae were not observed, the identification remains tentative but may represent a new species.
