Phyllium Illiger, 1798

Type species.

Phyllium siccifolium (Linnaeus, 1758), type locality: “Indies”.

Phyllium historically encompassed most leaf insect species, with numerous internal subdivisions and species groups, some recognized as unique for more than a century (e.g., Pulchriphyllium Griffini, 1898) and other divisions more recent (e.g., those found in Hennemann et al. 2009; Cumming et al. (2019a, 2020a). Within the first phylliid-wide molecular-based phylogeny, which covered nearly all recognized genera/subgenera/species groups ( Bank et al. 2021), Phyllium was adjusted only to include those species which form a monophyletic clade that shares significant morphological features with the type species Phyllium siccifolium (Linnaeus, 1758).
