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.
Pentalonia
Pentalonia is a genus of aphids in the family Aphididae, established by Coquerel in 1859. The genus contains at least four recognized species distributed across tropical and subtropical regions. Pentalonia nigronervosa, the banana aphid, is the most extensively studied species due to its role as the primary vector of Banana Bunchy Top Virus (BBTV), a devastating disease of banana crops worldwide. Recent morphometric and molecular studies have clarified that P. nigronervosa and P. caladii are distinct cryptic species with different host plant preferences.
