Eutetrapha cinnabarina ; Pu & Jin, 1991: 190; Hua, 2002: 208; Hua et al., 2009: 455; Löbl & Smetana, 2010: 323; Lin, 2015: 274, fig. 217581, 217582.

Supplementary description. Black spots in dorsal view lack pubescence, indicating a highly variable character, because pubescence can be rubbed off in many different ways. According to our observations, three spots on occiput and six spots on basal half of elytra are more or less stable in quantity, though size and shape are variable, while pronotal black spots are variable among four separated rounded spots ( Figs. 75, 76, 79, 80 ) to two longitudinal stripes ( Figs. 74, 77, 78 ), and black spots on apical half of elytra variable among one large patch ( Figs. 74, 77 ), five to eight separated spots ( Figs. 75, 76, 78–80 ). Male genitalia ( Figs. 81–85 ): Tergite VIII ( Figs. 81 a, 81c) as broad as long, apex emarginate at middle, with setae which are long at sides, shorter and sparser at middle. Spiculum gastrale slightly shorter than ringed part of tegmen, spiculum relictum about a half-length of spiculum gastrale. Tegmen ( Figs. 82 a, 82c, 82d) length about 2.9 mm; lateral lobes slender, each about 0.8 mm long and 0.2 mm wide ( Fig. 82 d); apex with fine setae which are shorter than half of lateral lobes; median lobe slightly curved ( Figs. 82 b, 85) in lateral view, shorter than tegmen; median struts shorter than half-length of median lobe; apex of ventral plate ( Fig. 82 a) pointed; endophallus nearly four times as long as median lobe, with two pairs of basal platelike sclerites (located behind apex of median struts), two bands of indistinct supporting armature, and three rod-like sclerites at end ( Fig. 83 ), two longer ones each about 2.5 mm, shorter than tegmen, short one about 2.2 mm. Female genitalia: spermathecal capsule ( Fig. 86 ) composed of an apical orb and a short and strongly curved stalk. Spiculum ventrale slightly longer than abdomen. In our observation, spiculum ventrale measured 8.5 mm for an adult compared with abdomen which measured 8.0 mm in ventral view.

Diagnosis. This species is similar to E. elegans Hayashi, 1966 from Taiwan, but can be separated by the elytron lacking a black spot between the middle spot and the first spot just after scutellum. The appendiculate tooth of claws of pro- and mesotarsi are more developed (four males of E. elegans Hayashi, 1966 had been observed). The black spots before elytra apex are variable in shape and quantity in both species, which is not a good diagnostic character.

Remarks. One photograph was reported by Wang (2014: 722, fig. 3418+1) from Guangxi, but the locality should be wrong. This species doesn’t distribute in Guangxi. Gansu and Shandong were reported by Wang (2014: 722, fig. 3419 and fig. 3419+1) as E. elegans , which were obviously E. cinnabarina and the localities could be correct.

Distribution. China: Hebei (new province record), Henan (new province record), Shaanxi (new province record), Hubei, Gansu, Shandong.
