Etymology“CDS is pleased to name this new species for his loving wife Jessi M. Siler for her endless support that has made all of this research possible. The name of the new species is derived from one of the local dialects spoken in the Philippines. The word ‘‘kadwa’’ is the Ilonggo term for friend and companion.”
