Molecular results.
Genetic analyses support the view that populations of
P. muronis
from
Japan
, the
Philippines
and
Western
Australia
are conspecific, with genetic divergences of no greater than 0.4% between them. In close harmony with the morphological analyses, the most closely related sampled congener is
P. macrophthalma
(average of 3.6 % divergent), followed by
P. binivirgata
(7.7%) and
P. algrahami
(8.6%) (fig. 1;
Table 1
).

Distribution and abundance.
Parapercis muronis
is now known from
Japan
and
Taiwan
(
Ho & Johnson, 2013
); the
Philippines
, from south-west of
Manila
Bay, Luzon Island (
14°00’N
120°19’01.2”E
) (this study) and off
Iloilo
City, Panay Island (ca
10°41’N
122°35’E
) (Motomura
et al
., 2017: 189); and
Australia
, from west-southwest of Barrow Island (
20°59’25”S
114°43’44”E
), northward to north-west of Cape Leveque (
14°59’25.2”S
121°39’09”E
),
Western
Australia
(this study) (fig. 8).
Parapercis muronis
appears relatively common off
Western
Australia
at depths of
126–210 m
where suitable habitat exists, with
27 specimens
known from 11 sites.
The record of
P. macrophthalma
from Western Australia by
Gloerfelt-Tarp & Kailola (1984: 242–243, 351)
is here confirmed as a misidentification of
P. muronis
based on our examination of their voucher specimens (AMS I.22807-038), and their colour photograph (p. 242, lower fig.).
Discussion.
Tanaka (1918)
described
P. muronis
based on a specimen from Tanabe,
Wakayama Prefecture
,
Japan
. It has subsequently been figured and reported from localities elsewhere in
Japan
(e.g.
Cantwell, 1964
: 254– 255;
Shinohara, 1997
: 553, fig. 4;
Shimida, 2002
: 1064) and in
Taiwan
(
Shen, 1984a
: pl. 115, fig. 371-12b). However,
Ho & Johnson (2013)
confirmed that some records from
Japan
(e.g.
Masuda
et al
., 1984
: pl. 260E), most illustrations from
Taiwan
(e.g.
Shen, 1984a
: pl. 115, fig. 371-12a, c) and all available voucher specimens from
Taiwan
at that time except for one (e.g.
Shen, 1984b
: 30) were misidentifications of
P. macrophthalma
(
Pietschmann, 1911
)
.
Research trawls off the north-west coast of
Western
Australia
by CSIRO vessels FRV
Soela
in
1982–1988
and FRV
Southern Surveyor
in 2007 resulted in the collection of
27 specimens
of
Parapercis
that appeared similar to populations of
P. muronis
from the northern hemisphere. Some individuals were initially identified as
P. macrophthalma
by G. Stroud in
Gloerfelt-Tarp & Kailola (1984: 242–243, 351)
. The species was later provisionally identified as
Parapercis
sp. 4 (e.g.
Johnson
et al
., 2014
), pending detailed morphological and genetic comparisons with specimens of
P. macrophthalma
and
P. muronis
from south-east Asia. The status of
P. macrophthalma
was clarified by
Ho & Johnson (2013)
, with the latter confirmed as distinct from
P. muronis
. Comparisons subsequently revealed that the Western Australian specimens were conspecific with
P. muronis
from
Japan
and the
Philippines
(fig. 1,
Tables 1
,
4–5
).
Meristic and morphometric data for the two hemisphere populations of
P. muronis
are compared in
Tables 4–5
and a genetic analysis is presented in fig. 1;
Table 1
. No significant differences in colouration were noted between the populations (fig. 7), proportional measurements (
Table 4
), or meristic data (
Tables 4–5
). Some minor morphometric variations between the populations were noted, with northern hemisphere populations having a slightly narrower body width (17.4–19.0% versus 18.8–22.2% SL) and shorter pelvic fins (20.0–23.1% SL versus 22.6–26.0% SL). However, these differences are possibly related to the condition and larger maximum size of some of the northern hemisphere specimens. The modal upper arch gill-raker count for northern hemisphere specimens is also slightly lower than for Australian specimens (5 versus 6), but this likely represents minor intraspecific variation.
