Eutetrapha laosensis ; Rondon & Breuning, 1970: 526, fig. 44e; Pu, 1991: 250; Pu & Jin, 1991: 190; Hua et al., 2009: 455; Löbl & Smetana, 2010: 323.

Supplementary description. Body length: 13.8–14.2 mm ( Rondon & Breuning 1970). Male is similar to female but slender, with antennae much longer than body (8th antennomere reaching elytral apex). Anterior claw of pro- and mesotarsal claws of male with a small tooth ( Figs. 146 a–c), female tarsal claws and metatarsal claws of male simple ( Fig. 143 ). Male genitalia ( Figs. 41–42 ): Tergite VIII ( Fig. 41 ) longer than broad, apex weakly projected, 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-length of spiculum gastrale. Tegmen ( Fig. 42 a) about 3.2 mm in length; lateral lobes slender, expanded before apex and then tapering apically, each about 0.8 mm long and 0.2 mm wide; apex with fine setae which are shorter than a half-length of lateral lobes; median lobe slightly curved ( Fig. 42 b) in lateral view, subequal to tegmen in length; median struts shorter than half-length of median lobe ( Fig. 42 c); apex of ventral plate ( Fig. 42 a) bluntly pointed; endophallus more than triple length of median lobe, with four pieces or more of basal plate-like sclerites (located behind apex of median struts), two bands of supporting armature, and three rod-like sclerites at end, each about 2.1 mm, much shorter than length of tegmen. Female genitalia: spermathecal capsule ( Fig. 43 ) composed of an apical orb and a curved stalk, strongly sclerotized part of stalk only a little longer than apical orb. Spiculum ventrale longer than abdomen. In our observation, spiculum ventrale measured 8.0 mm for an adult compared with abdomen which measured 6.4 mm in ventral view.

Diagnosis. This species is similar to Paraglenea sylvia Gressitt, 1951 by the two black maculae on the pronotum and four black maculae on each elytron, but can be easily distinguished by the two black maculae on the pronotum being much more developed and the first one on the elytron touching the lateral margin.
