Additional notes: Comment courtesy of Michael Geiser "There is a key to Indochinese Agetocera (and other Galerucinae genera) here: http://catalog.lib.kyushu-u.ac.jp/handle...There are 12 species in Indochina (three described after this key was published), mainly distinguished by the male antennae. So I don't think I can come up with any more precise IDeas for this one".
