 Maxillary palp terminal segment triangular, narrow; 



inner angle 90°, rounded; outer angle acute; longer than 



wide, width = 0.8 x length. Labial palp terminal segment 



triangular, extended on medial side, narrow, width = 0.8 x 



length. Labial palp width = 0.75 x maxillary palp width 



(Fig. 7f) . Mentum with plate broadly triangular, length = 



0.7 x basal width, sides straight, ridge medial extension 



acutely pointed (Figs. 8d, 20) . 



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

 to 3 diameters. Scutellum pentagonal, length = 0.5 x width. 

 Each elytron with 7 complete striae; stria VIII weak, 

 visible near humerus and apex; strial puncture size = 

 pronotal disc puncture; interval puncture size = 0.20 to 

 0.25 strial puncture. 



Prosternum weakly keeled and pinched anteriorly (Fig. 

 lOc-d) ; with foveate punctures in front of procoxa; coxal 

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

 surpassing coxae, basal width = 0.8 x length; prosternal 

 plate flat, apical width = 0.6 x basal width; base shallowly 

 concave . 



Mesosternum basal width = 1.5 x mesocoxal line length; 

 coxal lines straight to slightly arched; base sinuate, 

 medially lobed. Metasternal coxal lines not meeting at 

 middle, weakly recurved; lines short, reaching less than 

 0.25 distance to posterior lateral angle; line behind 

 mesocoxa deep, groove-like (Fig. 16b); sternum finely 

 punctate medially, few shallow coarse lateral punctures.
