Eutetrapha shiqianensis ; Hua et al., 2009: 455; Löbl & Smetana, 2010: 324; Lin, 2015: 278, figs. 217693, 217694.

Supplementary description. Male ( Fig. 45 , 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 =1): length 13.1 mm, width 3.8 mm. Female (n =2): length 15.5–18.3 mm, width 4.0– 4.7 mm. Male genitalia ( Figs. 46–50 ): Tergite VIII ( Figs. 46 a, 46c) as broad as long, apex almost rounded, slightly emarginate in middle, with setae which are moderate long at sides, and shorter but not sparser at middle. Spiculum gastrale subequal to length of ringed part of tegmen, spiculum relictum about a half-length of spiculum gastrale. Tegmen ( Figs. 47 a–c) about 3.7 mm in length; lateral lobes slender, each about 1.0 mm long and 0.3 mm wide; slightly expanded before apex and then obliquely rounded, with fine setae which are shorter than half-length of lateral lobes; median lobe slightly curved ( Fig. 48 b) in lateral view, slightly longer than tegmen (39:37); median struts much shorter than half-length of median lobe ( Fig. 48 c); ventral plate ( Figs. 48 a, 49) slightly turned to right side in ventral view, apex 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. 50 ), two longer ones each about 2.2 mm, much shorter than tegmen, short one about 2.1 mm. Female genitalia: spermathecal capsule ( Fig. 51 ) composed of an apical orb and a strongly curved stalk. Spiculum ventrale 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. laosensis Breuning, 1965 , but can be separated by the black markings on elytra less developed, especially the first one not touching lateral margin and the second one at most partially touching lateral margin. It is similar to Paraglenea sylvia Gressitt, 1951 by the two black maculae on pronotum and four black markings on each elytron, especially the first one on elytron with similar shape and size, but can be easily separated by the two black maculae on pronotum much more developed and the second and third ones on elytron with distinctly different shape.

Distribution. China: Guizhou, Fujian (new province record).
