Platyroptilon Westwood, 1850

This is a rather small genus of keroplatids with characteristic pectinate antennae. They are represented by about 13 species (not including the species dealt with here) found primarily pantropically (Evenhuis, 2006).

Of these, nine species are known from the Neotropical Region, two are known from the Australasian/Oceanian Region and two are known from the Oriental Region. The new species below from two provinces in China includes the first record of the genus from the Palaearctic Region (the specimen from Henan Province).

The genus is distinguished from other related genera by the following characters (Matile, 1990): flagellomeres pectinate; anepisternum and laterotergite bare; tibiae with setulae in regular rows on almost entire tibial length; basal cell normal, vein A1 almost reaching wing margin.
