Type material. Holotype ( ZSM Mol 20070760).

Type locality. Chile, off Concepcion , 36º22.19’S, 73º43.36’W, 846 m. GoogleMaps

Material examined. Southern Ocean , Heard Island, 52.5969°S, 71.9952°E, Locality HIMI-Aurora Bank, 310 m, cruise SC 26, Mol 37, benthic sled, 6 spms, BL GoogleMaps 10.0– 14.5 mm, ( TMAG, E 26178 View Materials ), 01.05.2003 .

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).

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) .
