 vertex puncture size = 1 x facet, separated 1 to 3 



diameters; epistome puncture size = 0.5 x facet, separated 



by 1 diameter. Antenna reaching middle of pronotum; 



antennomere III as long as next 3 antennomere combined; 



antennomere IX can be narrower than X; antennomeres X to XI 



asymmetrical, often weakly so and appearing symmetrical; 



antennomere XI transverse (similar to Fig. 6c) . 



Maxillary palp terminal segment triangular, securiform, 

 basally rounded, angles nearly 90°, length = 0.66 x width. 

 Labial palp terminal segment elongate, extended on medial 

 side, rounded basally, length = 0.75 x width. Labial palp 

 width = 0.5 x maxillary palp width (similar to Fig. 7a) . 

 Mentum with plate triangular, length = 0.9 x basal width, 

 sides convex, ridge medial extension acutely pointed 

 (similar to Fig. 8g) . 



Pronotal disc puncture size = 1 x facet, separated by 1 

 to 2 diameters; lateral punctures separated by 0.5 diameter. 

 Scutellum pentagonal, length = 0.5 x width. Each elytron 

 with 7 complete striae; stria VIII weak, visible on apical 

 half; strial puncture size = pronotal disc puncture; 

 intervals finely punctate. 



Prosternum keeled and pinched anteriorly; with (female) 

 or without (male) foveate punctures in front of procoxa; 

 coxal lines straight, length = 0.5 x sternal length, lines 

 barely surpassing coxae, basal width = 0.8 to 1.0 x length; 

 prosternal plate flat, apical width = 0.75 to 0.9 x basal 

 width; base shallowly concave.
