No, those are not relevant. You would be able to see spermathecae at that size. Avicularia and Caribena have very long, tube-like, spermathecae. Sometimes, it is difficult to see, because they can be laying down and not standing upright. Below are two examples - the first is a 2" Avicularia avicularia with both the spermathecae upright, and the second is a 2.5" Caribena versicolor with one upright and one laying down.
