Description

Length 6.7–7.0 mm; TL / EW = 1.20–1.29; PL / PW = 0.36–0.38; EL / EW = 1.00–1.11; EW / PW = 1.62–1.77.

Body ( Figures 2A View Figure 2 , 15C View Figure 15 ) round-oval, convex; surfaces covered with moderately long, sparse, appressed, yellow pubescence. Head, mouthparts, antennae, hypomeron, prosternum and fore legs yellow. Pronotum with central part dark brown to black with lateral margins yellow. Ventral side, scutellum, mid and hind legs dark brown. Elytron dark brown to black with two large, oval reddish maculae, one post basal and second pre-apical, not reaching elytral margins or suture.

Antenna ( Figure 1A View Figure 1 ) with antennomere 3 about 1.3 times longer than pedicel and almost as long as antennomeres 4–6 combined; antennomeres 4 and 5 at most as long as wide; antennomeres 6–8 transverse. Mandibles with dorsal apical and two subapical teeth large, pointed, sharp (sometimes blunt), dorsal apical tooth broad, shallowly excised, shorter than ventral apical one; all teeth without additional serration ( Figure 1F, G View Figure 1 ). Labrum broadly emarginate ( Figure 1B View Figure 1 ). Labium ( Figure 1C–E View Figure 1 ) with palpomere 1 transverse; palpomere 2 widening anteriorly, about twice as long as first one; terminal palpomere long, narrowing anteriorly, about 3 times as long as palpomere 1 and 1.4 times longer than palpomere 2. Maxillary palpomere 2 slightly longer than palpomere 3; palpomere 3 subquadrate; terminal palpomere large, somewhat securiform about twice as long as third one ( Figure 1H View Figure 1 ).

Prosternal process ( Figure 2B View Figure 2 ) rounded apically, parallel-sided; width of prosternal process about 1.7 times greater than length of prosternum in front of procoxae. Mesoventral process about 0.8 times as wide as mesocoxal diameter at the same position ( Figure 2C View Figure 2 ).
