Michaelsen divides this species into two subspecies, of which the 

 first has the species name, the second he terms labuensis. The former 

 has really two pairs of spermathecae, but the anterior pair are 

 small and in process of disappearance. The resemblance of this 

 species to A. halmaherce is considerable, especially in the approxi- 

 mation of generative pores and in the papillae.
