Very useful indeed! It supports the research by Paula, et. al (2014) just fine. On the website, the picture of the "A. brocklehursti" papal bulb showing the absence of the prolateral accessory keel between the prolateral superior and prolateral inferior keels has been shown by Paula, et. al. (2014) to be a variation of the papal bulb of A. geniculata. Compare the pictures to the paper (page 66, figure 13) and it matches up quite well. It doesn't, however, match up at all to the illustration of the A. theraphosoides papal bulb.Here is a link I found that may be useful between the A. geniculata and A. brocklehursti http://www.theraphosidae.cz/imagestar/acagen1.htm
The annotation by Richard Gallon at the bottom of the web page states he compared the hobby A. geniculata to Koch's type specimen of the same species and it matched up. This means the pet trade A. geniculata he examined was the real A. geniculata. It then goes on to say "Whether captive brocklehursti are conspecific with real brocklehursti we can't be 100% sure, but in the absence any evidence to the contrary (and given that they are phenotypically identical to dry material in the BM - presumable ID'ed by Cambridge himself), I see no reason to doubt it at the moment." Well, Cambridge's holotype of A. brocklehursti was examined by Paula, et. al. when conducting the study and found it to be synonymous with A. theraphosoides. Given Paula, et. al. (2014) we now have that evidence ten years after Gallon's statements were made to the contrary and can now determine that captive brocklehursti is conspecific with A. geniculata; not A. theraphosoides!

This was posted when I was writing my last reply. It also applies to these photos from Richard Gallon. Both pictures of the palpal bulbs clearly match to the pictures from Paula, et. al. (2014) showing the variation of the A. geniculata palpal bulb morphology- one with the accessory keel and one without.How about the two mature males "keel" pedipalps bulbs?
It depends on what taxon you are referring to. Sometimes the spermatheca is a generic character, sometimes it is a specific character, and in the case of the genus Haplopelma, it is used to group closely related species in the genus. The spermathecae of the Haplopelma spp. "minax group" has a different shape than the Haplopelma spp. "schmidti" group.A lot of us have been told that spermathecae is not valid to ID.
