P. metallica

I vote male

male with 90% certainty. Ventral sexing isn't full proof method sexing as the molt but it's apparent that the top pair of booklungs are very close to each other and I can see the prominent upside-down U shape in between which is a sure sign its a male. In females you would the lungs would further apart and furrow would start to be a bit visible.

Dorsally, you start to see the pokie patterns on the abdomen start to fade out. Sucks man. My first P.metallica was a MM.

Most likely it's a male. I agree with Jon3800, ventral sexing is not 100% accurate.
Though it's a likely male, an exuvium would be more accurate.

Thanks guys thats what I was thinking too
