Lost lovers linked at long last: elusive female mystery solved after a century of being placed in a different genus (Phasmatodea, Phylliidae).

After successful laboratory rearing of both males and females from a single clutch of eggs, the genus Redtenbacher, 1906 (described only from males) and the species group within Phyllium (Pulchriphyllium) Griffini, 1898 (described only from females) are found to be the opposite sexes of the same genus. This rearing observation finally elucidates the relationship of these two small body sized leaf insect groups which, for more than a century, have never been linked before. This paper synonymizes the species group with Redtenbacher, 1906 in order to create a singular and clearly defined taxonomic group.
