Supplementary description.
Males (n = 2): length
14.4–15.5 mm
, width
4.3–4.5 mm
. All claws appendiculate but anterior appendiculate tooth much longer and larger than posterior one (
Figs. 147
a, b), same situation to pro-, meso- and metatarsi.
Male genitalia
(
Figs. 89–92
): Tergite VIII (
Figs. 89
a, 89c) slightly broader than long, apex almost rounded with a small notch in middle, with setae which are long at sides, and shorter and sparser at middle. Spiculum gastrale subequal to ringed part of tegmen, spiculum relictum about a half-length of spiculum gastrale. Tegmen (
Figs. 90, 91
m) about 3.0 mm in length; lateral lobes slender, each about
0.6 mm
long and
0.15 mm
wide (
Fig. 92
); apex with fine setae which are longer than half of lateral lobes; median lobe slightly curved (
Fig. 90
b), subequal to tegmen in length; median struts slightly more than half-length of median lobe (
Fig. 90
c); apex of ventral plate (
Fig. 91
) bluntly pointed; endophallus nearly four times as long as median lobe plus median struts, with two pairs of basal plate-like sclerites (located behind apex of median struts), two bands of indistinct supporting armature, and three rod-like sclerites at end (
Fig. 90
), two longer ones each about
3.1 mm
, subequal to tegmen, short one about
2.5 mm
.
Diagnosis.
This species can be easily distinguished from other congeners by the distinct male claws and the lack of metallic scales.

Remarks.
The male claws of this species are distinct (
Figs. 147
a & 147b), exhibiting a combination of characters from the genera
Eutetrapha
and
Paraglenea
. Until a generic system of the tribe
Saperdini
is reconstructed based on further systematic study, we have decided to keep this species in the original genus
Eutetrapha
. Females are unknown but we predict that they should have simple claws.
