 and strongly narrowed apically; surface polished, impunctate, with 

 weak radiating rugae; jugum with three or four setigerous submarginal 

 punctures; ocelli small, separated from eye by space more than twice 

 transverse ocellar width; jugum ventrally and maxillary plate, except 

 posterior margin, polished, impunctate. Antennal segments: I, 0.26; 

 II, 0.26; III, 0.36; IV, 0.43; V, 0.51. Bucculae about as high as 

 labial II, evanescent posteriorly; labium reaching between middle 

 coxae. Labial segments: I, 0.46; II, 0.70; III, 0.60; IV, 0.36. 



Pronotum: Length more than half width, 1.49 :2. 69; anterior margin 

 moderately, doubly emarginate; lateral margin narrowing from near 

 base, not sinuate, with sLx setigerous punctures submarginally; 

 transverse impression postmedian, moderately impressed for full width, 

 marked by medially interrupted, regular row of coarse punctures; 

 anterior lobe without strong punctures except for less than six laterally; 

 posterior lobe with very few punctures clustered at middle. 



Scutellum: Length and width subequal, 1.66:1.69; disc polished, 

 with several scattered punctures except at base and apex. 



Hemelytron: Clavus and corium finely alutaceous; clavus with 

 single row of punctures; corium impunctate except for one complete 

 and one interrupted row of distinct punctures paralleling claval suture; 

 costa with one setigerous puncture; membranal suture straight, lateral 

 area not produced; membrane longer than basal width, surpassing 

 apex of abdomen. 



Propleuron: Weakly alutaceous, punctured in depression and ante- 

 rior to acetabulum; prosternal carinae less than half as high as labial II. 



Mesopleuron: Lateral area impunctate. 



Metapleuron: Lateral margin of evaporatorium slightly concave; 

 lateral area impunctate. 



Legs: Posterior tibia with distinct subbasal angulation and one 

 subapical spine on posteroventral margin. 



Sternites: Faintly alutaceous, impunctate. 



Terminalia: Genital capsule weakly alutaceous, with few scattered
