 Maxillary palp terminal segment triangular, sides 



rounded, lateral angle acute, medial angle nearly 90°, width 



= 2 x length. Labial palp terminal segment triangular, 



extended medially, sides rounded, angles nearly 90°, length 



= 0.8 x width. Labial palp width = 0.5 x maxillary palp 



width (similar to Fig. 7o) . Mentum with plate triangular, 



length = width, sides concave, apical angle rounded; ridge 



medial extension lacking (similar to Fig. 8h) . 



Pronotal disc puncture size = 0.75 x facet, separated 

 by 1 to 2 diameters; sightly denser laterally. Scutellum 

 pentagonal, sides short, length = 0.6 x width. Each elytron 

 with 7 complete striae; stria VIII present at base and 

 apical half; strial puncture size at base = pronotal disc 

 puncture, gradually becoming finer posteriorly; intervals 

 finely punctate, impressed, distinct. 



Prosternum strongly keeled and pinched anteriorly; with 

 (female) or without (male) foveate punctures in front of 

 procoxae; coxal lines slightly arched or straight, length = 

 0.5 x sternal length, lines barely surpassing coxae, length 

 = 0.6 to 0.75 x basal width; prosternal plate flat, apical 

 width = 0.6 x basal width; base shallowly concave. 



Mesosternum basal width = 3 x mesocoxal line length; 

 coxal lines straight, parallel; base sinuate. Metasternum 

 coxal lines meeting at middle, often crenate, recurved; 

 coxal lines extend 0.5 distance to posterior lateral angle; 

 sternum weakly shining medially, medial punctures fine, few
