Acanthomeniidae sp. (NHM_367)

Material examined.

NHM_367 NHMUK 20170078.1-2, collected 2013-10-19, 13.93307 -116.71628, 4182 m. http://data.nhm.ac.uk/object/c0577fc9-7302-4fec-bc8c-87a17a38bc91

Description.

Voucher specimen NHM_367, small solenogaster specimen, anterior end lacking; fragment ca. 2.5 mm long and 0.5 mm in maximum diameter (Fig. 25). Main epidermal sclerites are slender, elongate and pointed scales with a thin, symmetrical rim, and hollow acicular spicules with voluminous cavities, thin walls, and short, pointed tips. Data and material, including a permanent preparation of sclerites (1 slide), made available for future study.

Genetic data.

GenBank NHM_367 COI-MF157519.

Remarks.

The combination of scales and hollow spicules as main epidermal sclerites is diagnostic for the family Acanthomeniidae . Forms a unique monophyletic clade distinct from other AB01 specimens (Fig. 27). No genetic matches on GenBank.

Ecology.

Specimen collected from an epibenthic sledge tow across region of sediment and polymetallic nodules.
