Paraphrynus size.

[Arachnomaniac19]

What's the adult size of P. aztecus and P. cubensis?

The genus can be 15-35 mm according to Weygoldt's book. Sorry I can't be more specific

I know one of them is bigger than the other...I think aztecus is the larger one, and I think it's also larger than mexicanus, which gets up to 22mm. I think cubensis is smaller than mexicanus, as well. However, I am very unsure about that memory, it's based entirely on one picture of three adults that was supposed to be about standard for sizes for each species, and I may be misremembering which species were represented and which was which.

I think you're right. My aztecus is larger than my two cubensis.

That may be, but if so, it's for the wrong reason. I found the original picture, and it was actually Paraphrynus raptator, P. mexicanus, and Phrynus marginemaculatus.

You'll have to tell us what the final size is for the sake of science. What stage instar are yours, or are you no longer keeping track?

Can we have some pictures?

The bottom one is aztecus and the top two are my cubensis.

 

[Arachnomaniac19]

No idea on the instars though.

both species belong to the smaller-middle sized Paraphrynus species.
aztecus get a bit bigger and grow faster but starting reproducing later in life, instead cubensis is after 9-10 months ready to breed but from this date on the continue growing very slowly, but after 4 years or so, the have nearly the size of aztecus after 2.5 years.
