Comment	Habitat: This species is apparently largely arboreal, and has been found in Coco- thrinax argentata and B. simaruba.
Etymology	The species name, argentum, is the nominative Latin word for silver, referencing the silver coloration of the first specimen encountered in July 2015 as well as its location in a silver palm (Cocothrinax argentata) when encountered.
