Why does
this specimen look nothing like the others in this species? Is this what the males look like or is it a different form?

Spiders are dimorphic
Great question. Spiders are dimorphic. Look at the size difference too. You'll find a drawing of this male in Levi's 1978 paper on the genus, Bulletin of the Museum of Comparative Zoology, p. 439.
