Supplementary description. Male ( Figs. 12 – 13 , 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 12.6 mm , width 4.0 mm. Female (n =2): length 15.5–17.0 mm, width 5.0– 5.7 mm . Male genitalia ( Figs. 15–20 ): Tergite VIII ( Figs. 15 a, 15c) slightly broader than long, apex almost rounded, slightly emarginate 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 of spiculum gastrale in length. Tegmen ( Figs. 16 a–c) about 3.1 mm in length; lateral lobes stout, each about 0.7 mm long and 0.3 mm wide; gradually narrower apically (from outer), apex with several fine setae which are shorter than half of length of lateral lobes; median lobe slightly curved ( Fig. 17 b) in lateral view, slightly shorter than tegmen (28:31); median struts about half-length of median lobe ( Fig. 17 b); apex of ventral plate ( Fig. 18 ) bluntly 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. 20 ), two longer rods each about 2.1 mm , much shorter than tegmen, short rod about 1.9 mm . Female genitalia : spermathecal capsule ( Fig. 21 ) composed of an apical orb and a stalk. Spiculum ventrale longer than abdomen. In our observation, spiculum ventrale measured 8.4 mm for an adult compared with abdomen which measured 7.7 mm in ventral view. FIGURES 12–14. Eutetrapha complexa Pu & Jin, 1991 , habitus. 12.

This species resembles E. sedecimpunctata ( Motschulsky, 1860 ) by the tawny pubescence and black spots on pronotum and elytra, but can be easily distinguished by having the elytron with a row of punctures between humeral carinae instead of two rows, punctures sparser between the exterior margin and external carina of humerus and black maculae on elytra larger and positioned near lateral margin ( Pu & Jin 1991, partially modified ).
