Acrotrichinae
Acrotrichinae is a subfamily of featherwing beetles (Ptiliidae) first established by Reitter in 1909. Members of this subfamily include some of the smallest beetles known, with body lengths often under 1 mm. The subfamily contains the genus Phytotelmatrichis, which was discovered exclusively in phytotelmata of Zingiberales plants in southern Peru, suggesting specialized habitat associations within the group.
