I have not seen the type of this species, but Mexican examples referred to it were 
identified by the Rev. O. Pickard-Cambridge. The vulva of the female consists of a 
black base with an irregular dull red excrescence, the latter being probably an 
excretion, which conceals the true form of the external parts.

I have not seen the type of this species, but the Guatemalan specimen figured was 
identified by the Rev. O. Pickard-Cambridge and labelled by him A. obtusus. It 
entirely agrees with his figures of the latter, and is also identical with the type of 
A, linguatus now before me. |
