The species is close to A. uxyptera, Wlk., also from Borueo, 

 which exhibits the same characters of punctuation of the 

 tegmina; but A. oxijptera is smaller, more rufous in colour, 

 the proportions of the pronotum are different and the pro- 

 notum is less closely punctate, but more densely covered 

 with eastaneous dots. Both species can be distinguished 

 from A. acutipennis, Sauss., by their larger size.
