 Prosternum keeled and strongly pinched anteriorly; 



without foveate punctures in front of procoxa; coxal lines 



inwardly arched, length = 0.5 x sternal length, lines barely 



surpassing coxae, line length = 0.75 x basal width; 



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



base shallowly concave. 



Mesosternum basal width = 2 x mesocoxal line length; 

 coxal lines arched inwardly; base sinuate, lobed medially. 

 Metasternum coxal lines recurved, meet medially in a weak 

 tooth; coxal line extends 0.5 distance to posterior lateral 

 angle; sternum with medial punctures fine, coarse lateral 

 punctures weakly impressed. 



First visible abdominal sternite with coxal lines 

 reaching 0.25 to posterior edge; rounded between metacoxae. 



Male genitalia with median lobe moderately arched, 

 narrowed to a point; internal sac without noticeable 

 sclerotized structures; flagellum gradually narrowing toward 

 apex, length = 1.1 x median lobe length (Fig. 125a); base of 

 flagellum straight, sclerite at base claw-shaped (Fig. 125b- 

 d) (2 dissected) . 



Female unknown. 



Presence of stridulatory files on occipital region of 

 head unknown (heads retracted) . Both males have the 

 prosternum broadly expanded onto, and nearly covering, the 

 pronotal epipleuron; possibly sexual dimorphism. 



Variation . One specimen has a faint elongate marking 

 at the center of the pronotal disc. This pale spot is
