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.

Distribution. China: Sichuan (new province record), Yunnan.
