, Porto Velho, U. H. Samuel (IBSP 9506). This specimen was not examined here, as it was destroyed by a fire in the Instituto Butantan collection buildings in 2010. Other specimens examined from nearby localities show the female has very distinct spermathecae, slender and with lobes only on their tips (Figs 18, 23). The male has a more slender embolus, mainly on its base (Figs 14-15, 27). Males, females and immatures have distinct color patterns from those of

For this reason, figures of male palpal bulb and spermathecae were included to show the morphological variation in the specimens from the two distant localities (Figs 19-21, 26).
