mm kaeng krachan already?

Very strange indeed. Do you have any additional photos of the pedipalps? They certainly look male from this angle

hes def a mature male. couldnt believe it when he crawled out. I have a mature H. Pulchripes thats barely over 3" as well. The pulchripes was a .5" sling as well purchased 02-07-19 and matured out on 05-13-19. Both kept around 80-85 degrees all winter and fed a small to medium cricket weekly

@Rbed2 Sometimes males mature earlier/smaller than you expect.

He's still a nice-looking spider though. Are you planning to breed him or send him to someone with a female?
