Name
Spiophanes anoculata Hartman, 1960 – Wikispecies link – Pensoft Profile
Diagnosis
Prostomium broad anteriorly, bell-shaped, with short but distinct anterolateral horns, posteriorly short straight extension with papilliform occipital antenna. Eyes absent in material from the present study but four minute, deeply embedded, red eyes sometimes present in material from the east Pacific. Dorsal ciliated organs as continuous ciliated grooves to the end of chaetiger 2, thereafter as segmental dorsal ciliated grooves interrupted by segmental furrows, after chaetiger 18 or later changing again to continuous double lines (missing in IN2017_V03 specimens); ciliated grooves bordered by pigment of dark orange or ochre colour. Chaetal spreader of ‘0+1’ type, present on chaetigers 5–8, opening of glandular organs on chaetigers 9–14 as simple vertical slits. Parapodial lamellae not well preserved in most specimens. Chaetiger 1 bearing stout, crook-like chaeta in neuropodium. Notochaetae mostly simple capillaries and capillaries with narrow sheath arranged in a tuft, neurochaetae capillaries with sheaths arranged in two or three rows, stout capillaries in anterior and middle body region; from chaetigers 15 neuropodia with quadridentate hooded hooks; stout granulated sabre chaetae starting on chaetigers 4, very long in anterior chaetigers. Ventrolateral intersegmental pouches absent.
Remarks
Specimens are in good agreement with former descriptions, with the most conspicuous character being the metameric dorsal ciliated organs. See Meißner (2005)[1] and Blake (1996b)[2] for details of parapodial lamellae, chaetal arrangement, and details of chaetae. However, the description by Blake (1996b)[2] deviates from Australian material and also from former descriptions of specimens from the NE Pacific Ocean (Meißner 2005[1]) in that Blake describes continuous ciliated grooves reaching the end of chaetigers 3 rather than 2, and sabre chaetae to start on chaetigers 15 instead of chaetiger 4.
Records
5 specimens. Suppl. material 1: ops. 27, 40, 54, 79 (AM).
