What kind of Brazilian Arthropoda is this?
I was fooled by the red marks in its back, that made me believe they were each pair of marks in a segment. Looks like they're distributed in one pair of red marks for each 2 segments. Maybe that's a mimic of some similar Diplopoda (which usually have such colored marks, see for instance Rudiloria)?

Looks like it's some species of Scutigera or some related group.
