I have found two millipedes in my area that I would like to identify. Does anyone recognize these? I photographed both at about 6,500 feet outside Cali, Colombia. I've been told locally the bite of the first produces a pretty nasty reaction. I know nothing about the second one but wonder if the bright colors function as a warning like the colors of poison arrow frogs. Both are maybe 14 cm long but I haven't measured them. Any info would be most welcome.
