Supplementary description.
Male claws: anterior claw of pro- and mesotarsi is toothed at base (
Fig. 146
), others simple. Female claws simple.
Male genitalia
(
Figs. 139–141
): Tergite VIII (
Figs. 139
a, 139c) slightly broader than long, apex rounded, with setae which are long and dense at sides, and shorter atmiddle. Spiculum gastrale subequal to ringed part of tegmen in length, spiculum relictum about one half-length of spiculum gastrale. Tegmen (
Fig. 140
d) about
2.7 mm
in length; lateral lobes stout, slightly tapering apically, each about
0.5 mm
long and
0.2 mm
wide; apex with fine setae which are longer than lateral lobes; median lobe slightly curved (
Fig. 140
b) in lateral view, slightly longer than tegmen (29:27); median struts more than half-length of median lobe (
Fig. 140
c); apex of ventral plate (
Fig. 140
d) rounded; endophallus more than triple length of median lobe, with four pieces of basal plate-like sclerites (located behind apex of median struts), two bands of supporting armature, and three rod-like sclerites at end, which are about
2.9 mm
in length, slightly longer than tegmen.
Female genitalia
: spermathecal capsule (
Fig. 142
) composed of an apical orb and a curved stalk, stalk only a little longer than apical orb. Spiculum ventrale longer than abdomen. In our observation, spiculum ventrale measured
6.2 mm
for an adult compared with abdomen which measured
5.8 mm
in ventral view.
Remarks.
Matsushi (1933)
first reported “
Formosa
” in the distribution list of this species, mentioning
Formosa
(Taihoku, Kankô) as the exact locality. Later,
Breuning (1952)
,
Hua (2002)
,
Hua
et al.
, (2009)
and
Löbl & Smetana (2010)
followed him to list
Formosa
or
Taiwan
as one of the localities. However, other authors considered it as a species endemic to
Japan
(
Gressitt 1951
;
Samuelson 1965
; Kurihara & A. Saito 2007), and
Chou (2008)
did not mention this species in his Taiwanese fauna list. We failed to find any specimens from
Taiwan
to confirm the report during this study.
Lee (1987)
did not mention this species in his Korean faunal list, while
Jang, Lee & Choi (2015)
listed it without photographs or specimens.
Hua (2002)
included
Korea
and this was followed by
Hua
et al.
(2009)
and
Löbl & Smetana (2010)
. We could not confirm this locality either.
The first author believes that the
Taiwan
and
South Korea
records were based on misidentifications of
Saperda
(
Lopezcolonia
)
tetrastigma
Bates, 1879
or other species with four black spots on pronotum and four black spots on each elytron. Therefore, the distribution of this species is endemic to
Japan
.
This species does not belong in the genus
Eutetrapha
because of the absence of distinct lateral elytral carinae and may instead belong in the genus
Saperda
(
Lopezcolonia
)
. Actually, the elytral lateral margins are quite similar to that of
Saperda
(
Lopezcolonia
)
alberti
Plavilstshikov, 1916
and
Saperda
(
Lopezcolonia
)
perforata
(Pallas, 1773)
. Although a systematic study of all
Saperdini
has not yet been undertaken, we propose the new combination based on the morphological study conducted by the first author and a preliminary molecular analysis conducted by Dr. Nonaka Masaru. We believe this species is sister to
Saperda
(
Lopezcolonia
)
octomaculata
Blessig, 1872
and
Saperda
(
Lopezcolonia
)
subobliterata
Pic, 1910
, while quite far from
E

sedecimpunctata
