Leodamas cirratus : Blake 2017: 68–71 , figs 29D–H; 30. Material examined. No material examined. Type locality. Off the South East coast of Argentina . Remarks : Leodamas cirratus was described from southwest Argentina ( Ehlers 1897 ), and Leodamas ohlini from the Strait of Magellan ( Ehlers 1900 , 1901 ). According to Hartman (1957), these two species share the presence of a single subpodal papilla on the last thoracic and anterior abdominal segments. The species differ mainly owing to the number of thoracic segments ( 20–21 in L. ohlini vs 26–31 in L. cirratus ). Additionally, L. ohlini lacks podal papillae, whereas L. cirratus bears one podal lobe in the six last thoracic neuropodia. Leodamas ohlini was recorded from Southern California, Mexico (Hartman 1957), and New Zealand ( Augener 1926 ). Additionally, there are records of this species from Victoria and Tasmania ( Atlas of Living Australia 2020 ). Blake (2017) , after an investigation of the type material and additional material from South America and Antarctica , redescribed L. cirratus and synonymised L. ohlini with L. cirratus . Whether the Australian and New Zealand specimens belong to this species needs to be confirmed. Sun et al. (2018, p.134) confused L. fimbriatus and L. cirratus in the key for Leodamas species stating the presence of abdominal notopodial aciculae and branchiae from 7 th chaetiger in L. cirratus , whereas these characters are diagnostic of L. fimriatus . Distribution ( based on literature). South West Atlantic, Strait of Magellan, South Orkney Islands , ( Ehlers 1897 , 1900 , 1901 ; Blake 2017 ), Mexico (Hartman 1957), Australia ( Atlas of Living Australia 2020 ), New Zealand ( Augener 1926 ). Habitat. Subtidal.
