About the size, description lists body length and pronotum length. You need to combine the two to get full length which adds to 55 mm so that's very close to the size of hobby roseni
Interesting species I found near border in AZ. Juveniles have red palps (not seen in P. carolynae) and adults are darker than typical P. carolynae.
Picture shows both species for comparison.
Unfortunately won't be available till the 3rd generation grows up to about 1" which will probably take about a year. I made a mistake of trading away too many breeding groups last year
Unfortunately the original 11 I had all died when I let my friend babysit them for few weeks while I was out of town. However, I was able to collect 8 more specimens this year that are presumably 7 males and 1 female so hopefully I'll have better luck this time.
