Jasmineira sp. 2  

Diagnosis.

Medium to large body size. Branchial crown with 21 pairs of radioles, lobes involute ventrally. Collar without lateral incisions (not four-lobed), dorsally high with pockets and fused to faecal groove, ventrally high with small midventral incision, lappets small. Dorsal lips with long radiolar appendages, length of ~ 2-3 thoracic segments. Glandular girdle present on chaetiger 2. Thoracic superior notochaetae narrowly-hooded, inferior chaetae paleate with long mucro, bayonet chaetae present. Thoracic uncini long-handled, acicular with sub-distal swelling on shaft, companion chaetae absent. Abdominal neurochaetae elongate, narrowly-hooded; uncini avicular with elongate neck, small breast, short-handled.

Remarks.

One large specimen is in three pieces with most radioles split off at abscission zone, but present in sample; another large specimen is too degraded by poor preservation to distinguish anything other than chaetae. These are different to the species found in the 2017 GAB survey (recorded as ' Jasmineira   sp.'; MacIntosh et al. 2018: additional file 2), which has a four-lobed collar.

Records.

2 specimens. Suppl. material 1: ops 31, 115 ( AM).
