I've been trying and trying to get a good shot of his underside, but they just don't come out nice. If it's any help, he/she doesn't seem to have a very distinct little "pot-belly" like many female Ts do, but I haven't seen an epiandrous (spelling?) bullseye on him/her either... :S he/she's been in pre-molt for a while though, so I guess I'll just have to wait until he/she gives up the old skin to see...
