I was not sure about this specimen until I dissected the epigynum; even then, I was initially led astray as I focused on the dorsal view of A. emertoni depicted in Paquin & Dupérré, 2003.* But once I flipped the whole structure over and looked at things ventrally, it all became clear; speaking of which, cleared in clove oil.

* If you haven't already done so, it's worth looking at the corrections they published in Zootaxa (2006) as a number of the views of the spermathecae are incorrectly marked "dorsale" when they are actually "ventrale".
