Taxonomic Notes
ZeuzerocossusYakovlev**. Yakovlev (2008b) placed cinereus in this new genus, defining it primarily on the unusual, partially bipectinate antennae as described in Part 1. The male genitalia and this antennal structure place the new genus close to Ronaldocossus Yakovlev (type species brechlini Yakovlev) from Sulawesi. On these grounds, Yakovlev placed both genera in a new tribe, the Zeuzerocossini, but did not indicate any features that were autapomorphic to the Cossini as a presumed sister-group; this action rendered the Cossini paraphyletic. Yakovlev recorded cinereus from central Thailand.
