Love the Irminia! I have two, one is just a bit bigger than yours. I'm like jeff, I'm on my phone and I too don't see anything that says male right off the bat. If you can, you can take an eye dropper of warm water and drop a few drops on it to get it to "loosen" up so you can get a better look. My smaller one destroyed his molt last time so I couldn't get a look at it. I think it did it on purpose.

I still don't know what to look for . I let the local club people take care of that lol. They are so great here in Nebraska!
If I can ever got back on the computer I will try to walk you through it If the molt is in good condition and big enough you can feel free to send it in the mail for me to look at.
