Supplementary description (genitalia). Male genitalia (Figs. 5–7): Tergite VIII (Figs. 5 a & 5c) broader than long; apex truncated, with setae which are long at sides, and shorter and sparser at middle. Spiculum gastrale slightly shorter than ringed part of tegmen, spiculum relictum about one half of spiculum gastrale in length. Tegmen (Figs. 6 a–6c) about 3.2 mm in length; lateral lobes (Figs. 7 a–7b) slender, tapering apically, each about 0.8 mm long and 0.2 mm wide; apex with fine setae which are shorter than half of length of lateral lobes; median lobe slightly curved (Fig. 6 b) in lateral view, shorter than tegmen (7:8); median struts about half-length of median lobe (Fig. 6 c); apex of ventral plate (Fig. 7 a) pointed; endophallus more than triple length of median lobe, with four pieces of basal plate-like sclerites (located behind apex of median struts), and three rod-like sclerites at end, which are about 2.0 mm, much shorter than tegmen. Female genitalia: spermathecal capsule (Fig. 8) 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 10.8 mm for an adult with abdomen measured 9.2 mm in ventral view.
Host plants. Acer sp. (Aceraceae), Populus sp. (Salicaceae), Robinia pseudoacacia Linnaeus (Fabaceae), Salix sp. (Salicaceae), Tilia cordata Miller (Tiliaceae), Tilia japonica (Miquel) Simonkai (Tiliaceae).
Favorite host plants. Salix cardiophylla Trautvetter & Meyer (Salicaceae), Senecio sp. (Asteraceae).
Remarks. The distribution record from Hubei was mentioned by Hua without reference material or literature cited (Hua 2002; Hua et al. 2009) and followed by Löbl & Smetana (2010). We could not examine any specimens from Hubei, but found three specimens from Hebei.
For the Taiwanese fauna, E. sedecimpunctata was recorded by Chen et al. (1959), including some ecological notes. Meanwhile, Menesia sulphurata (Gebler, 1825) the occurence from Taiwan was not included in Chen et al. (1959), Hua (2002) and Hua et al. (2009). Thus, we conclude that these authors misapplied Saperda sulphurata Matsumura, 1906 (a homonym of Saperda sulphurata Gebler, 1825 and a synonym of Eutetrapha sedecimpunctata) to Saperda sulphurata Gebler, 1825. As a result, we exclude Hubei and Taiwan, and add Hebei to the distribution of this species.
The black maculae on the pronotum and elytra are quite variable, and several varieties, aberration or morphs were described as infrasubspecific taxa. Also, E. duodecimpunctata = 16-punctata (Motschulsky, 1960) or E. variicornis Bates, 1884 have been synonymized with E. sedecimpunctata.
Distribution. China: Heilongjiang, Jilin, Liaoning, Hebei (new province record), Shaanxi; Russia, North Korea, South Korea, Japan.
