Leptopus is one of eight genera in the tribe Poranthereae[3] and comprises 9 species.[4] It is the sister of Actephila. The type species is Leptopus cordifolius.[5] The name is derived from two Greek words, leptos, "thin, slender, or small", and pous, "foot", a reference to slender pedicels.[6] The genus was first described in 1836[7][8] and revised in 2009.[9]
Leptopus fangdingianus had been placed by some authors in a separate genus, Archileptopus, but it was shown in 2007 that recognition of Archileptopus makes Leptopus paraphyletic.[10] Phyllanthopsis phyllanthoides has been placed in Leptopus as well as in Andrachne. In 2007, it was shown to not properly belong to either genus and in 2008 was assigned to a new genus, Phyllanthopsis.[4]
