4" Pelinobius muticus [ventral sexing]
King baboon tarantula. Reaching 4 inches in size. Is it possible to sex? I never seen the molts.... Would love to examine a molt if it would ever show it!
Ooo wow, how you determine? I have another baboon but never get a good pic lol! I'll try to get a pic of the other another day
I have a ~6" female of this species, as well as a male around the same size as your specimen; their ventrals are very different, with my female's having that nice pronounced gonoslit like yours does. A male would have a flatter, less curved lip, and most importantly would have epiandrous fusillae, which yours does not appear to have.
