Females get their white coloration usually around 2-3 inches. They also have a completely different build, which also becomes more evident around that size. They are much more stocky and have much larger/wider chelicerae as opposed to the much more narrow chelicerae that males have. That last part applies to most species though. The white coloration is unmistakable on the females though.

Yup. That's how it is for a good majority of tarantulas.
Does this mean that it is during their final molt that the abdomen of males become considerably small? Besides the pedipalps and tibial hooks.

Often times, yes but as I've mentioned before, abdomen size is not a very reliable way to determine whether you've got a male or not. Species that are sexually dimorphic usually look completely different after their ultimate molt. With some species you can see the male features start to show up even when they're at a pretty young age. With Pokies it's very easy to sex them at as young as 2 inches, by just looking at the dorsal markings, the black on the carapace is a lot more prominent on females where as it is more faded on the males. With certain species, you can also tell by looking at the size/shape of the chelicerae.

I agree, would not mind having a male of this species. ;)
Really? That is a fun trivia to note. :)
I wasn't really on the look out for this T but I just got one irminia sling. Definitely not a beginner species so hope you can help me with its care @Chubbs
Right now, it is staying put at the base of the bark and on top of the substrate. It looks like it's about to molt. Really a win-win for me be it male or female. :cool:

Well what's done is done. Unfortunately all I can really help you with all that much is the care/husbandry part. Care is pretty much identical to that of all Psalmopoeus species. Arboreal-set up, good cross-ventilation, can be kept more moist than Avics, all they really need is a water dish but if you're really insistent about misting, just don't overdo it and make sure you have adequate ventilation to do so. You don't want wet substrate, even species that truly need moist sub like Haplopelma, Ephebopus, Megaphobema, Theraphosa, and so on still need to have time in between for the enclosure to dry out. I use moss for pretty much all of my enclosures, so that helps. Give slings a few inches of substrate since they will dig a bit, and provide them with a slab of cork bark or something to climb on, and they will usually build a web at the base of it from the ground-up. Admire its looks while you can because Psalmos are pretty reclusive (except maybe for cambridgei), and irminia is probably the shyest out of them all, and will usually spend most of their time hiding. Like many arboreals, they will also attach substrate to the silk for camouflage purposes. They grow fairly quickly. Much like a lot of the Old Worlds, these also don't like lights being shined directly on them, so try to avoid doing that :p Give it some time to settle in for a few days before opening the enclosure unless you absolutely have to. Species with more nervous and/or defensive temperaments are best left alone for a while after they are first rehoused, and if allowed to start building a retreat, otherwise they're more likely to race up the side and out of the enclosure when disturbed. Good luck with your sling.

These are rather small as mature specimens then. Hoped you have bred him before he passed.
Yup that's rather typical of most of the baboon species and certain Asian species as well. Males often times mature at sizes as small as 2 1/2 to 3 inches. Some South American species can mature at pretty small sizes as well.
