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
.
