Taxonomic Remarks
Belongs to the Notospermus geniculatus cryptic species complex, which is found globally in warm waters. Appears most closely related to the true N. geniculatus (per Kajihara et al. 2022; BOLD BIN AEB6981), and another local undescribed species, Notospermus sp. SMSA074, but can be distinguished from those by COI sequence data (~12-13% divergent).

Description of Material
Body 200 mm long, 10 mm wide, dorso-ventrally flattened and widest in the midgut region, more cylindrical and slender in the foregut region, without a caudal cirrus. Body colour uniform taupe or dark hazel brown dorsally and ventrally, except for white head margin and several narrow white transverse rings encircling the body. The anterior-most band is ½ to 2/3rds of the way from the anterior tip of head to posterior end of cephalic slits and has a prominent forward-pointing mid-dorsal peak. Cephalic lobe sub-rectangular, about twice as long as it is wide. The anterior margin can appear deeply notched or slightly pointed depending on the state of contraction and movement. Red cerebral ganglia visible through body wall and lateral slits. Ocelli lacking or not detectable externally.
Ecology
Subtidal, found by a diver.
Distribution
Currently only known from Port Victoria jetty, South Australia, Australia.
