Anyone Know When Platycryptus Undatus Can Be Sexed?

[Nicole C G]

So, I’ve had this Platycryptus undatus juvenile (jumping spider) and everyone says that males can be identified by an orange stripe under their eyes. However, I was wondering if this is always 100% true.
Here is my Jumper

Mori’s new body after molt


Previous body

Mori seems to have a slightly orange or brown stripe under the eyes. However I’m unsure how sure I can be. Mostly because the other day I saw an adult Platycryptus undatus who had the stripe, but didn’t have swollen pedipalps, and had the shape and size of a female. See:

Mori is too young to be sexed. that adult one does appear to be a male however.

That’s what I thought, It just kinda been driving be crazy not knowing if it’s a male or a female so I had to ask if there’s even a small chance I could know
Thanks for your help!
