@JamesGSixx That's because your T. is still small and not mature. As a T. grows and becomes mature, the spermathecae becomes more developed and yours is small and not an adult yet. But in due time its spermathecae will look like that. And that picture is a pic of a fully mature T. spermathecae.
@JamesGSixx The best resource for that kind of information is World Spider Catalogue, although you won't find samples of male accessory organs, because they are not used by taxonomists to identify species. You will find spermathecae samples, because those are used for identification. You need to sign up for an account, but it is always free. You will find everything you need there and I access it all the time. You can find it at World Spider Catalogue.
@JamesGSixx I initially thought it was female until I looked at a picture of my own Davus pentaloris, which was not much bigger than yours (1.5"). Even when small, the spermathecae are close together, not spaced apart like in yours.
