Trosia sp.
From Wikipedia: Megalopygidae is the technical name of a group of insect species known generally as crinkled flannel moths, or simply Flannel Moths. They occur in North America (11 species) and the New World tropics. The larvae are called Puss Caterpillars, and with their long hairs, resemble cotton balls. They have venomous spines that can cause a painful sting and inflammation lasting for several days. In some cases, the sting may cause headache, nausea, and shock-like symptoms.
Megalopygidae, Trosia sp., unfortunately too many "identical" around. I only know T. incostata and T. nigropunctigera from Costa Rica. Bold has some more from there.
