discussion
Remarks. The studied specimen (TMAG E 26178) has BL 11.0 mm and 10 gills per side arranged from valve VII to anus, and a 4.3 mm long radula with 57 transverse rows of mature teeth. Like specimens of this species living off the South Shetland Islands (Sirenko 2015), the Australian specimens I studied (Sirenko 2020) have smooth dorsal scales, which in my opinion is intraspecific variability. Leptochiton laurae belongs to the group of L. sykesi (Sirenko 2020).

Distribution. Off Chile, from 34.5 ° S to the Magellan Strait and Beagle Channel, South Orkney, South Shetland, Kerguelen, Heard and Crozet Islands, south western Australia and New Zealand, 88 – 1210 m (Sirenko 2020).
