Sexual dimorphism in Psalmopoeus pulcher

[BillsSpider]

It's been a while since researching so if someone could refresh my memory, do P.pulcher turn that grey like P.irminia or P.cambridgei? Did a rehouse of my P.pulcher as it was getting to big for the old enclosure and it looks decidedly male although I couldn't confirm hooks or emboli yet

That's not a mature male, which is when the males of Psalmopoeus become dimorphic from the females.

I also don't think that's P. pulcher, rather it looks like a member of Tapinauchenius.

Yes, Psalmopoeus pulcher mature males are sexually dimorphic from females. Before the male matures they look the same as female specimens, your tarantula is 100% not a mature male.

Looks like a pulcher to me, probably a large juvenile.

Ok, that's reasonable. I retract my statement. I didn't initially see photos of juveniles which do look more like this spider, so the solid abdomen colour and slightly purple-ish hue on the legs was throwing me off. As I've never raised this species, I will defer to those with experience.

Probably my fault, I used flash which I don't usually do and you don't see that purple without flash, it just looks tan/brown

They're only dimorphic as mature specimens. Immature specimens look the same.

Mines never had that pattern on the abdomen, it's always been a really dark brown, almost black?

Juvenile colors, it'll get the abdomen markings as an adult.

That's what they look like as juvies, the pattern appears as they grow. My female when I got her.
