Eutetrapha elegans Hayashi, 1966: 9, pl. 1, fig. 6. Type locality: China, Taiwan, Hosakei. Type depository: NSMT.

Supplementary description. Male (Fig. 67, described for first time) matches female quite well, with antennae slightly longer, body slender, anterior claw of pro- and mesotarsi appendiculate with short tooth (Figs. 146 a–c). Male (n = 3): length 10.8–12.4 mm, width 3.0– 3.5 mm. Male genitalia (Figs. 69–73): Tergite VIII (Figs. 69 a, 69c) as broad as long, apex emarginate in middle, with setae which are moderate long at sides, and much shorter and sparser at middle. Spiculum gastrale subequal to ringed part of tegmen in length, spiculum relictum less than a halflength of spiculum gastrale. Tegmen (Figs. 70 a–c) length about 2.7 mm; lateral lobes slender, each about 0.8 mm long and 0.2 mm wide; apex, with fine setae which are shorter than one fifth of length of lateral lobes; median lobe slightly curved (Fig. 72 b) in lateral view, slightly shorter than tegmen (23:27); median struts slightly shorter than half-length of median lobe (Fig. 72 c); apex of ventral plate (Fig. 72 a) pointed; 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 (Fig. 73), which are about 2.2 mm, shorter than tegmen.
Remarks. The black spots lack reddish pubescence and are variable in shape from those located at apical half of elytral. The female specimen from Yunnan matches the holotype from Taiwan quite well except for lacking pubescence behind the upper eye lobes and middle line of occiput. It could be a new species, however, until more material from Yunnan and Taiwan become available, we consider it as an individual whose pubescence was strongly rubbed.
Distribution. China: Taiwan, Yunnan (new province record).
