Leaylia norfolkiana is the sole species in this genus. Formerly described under Bargylia ( Wygodzinsky 1956 ) , it was subsequently given its own monotypic genus based on the diagnostic characters listed above (labium shape, metanotum length and male genitalia) by Wygodzinsky (1966) . While similar in appearance to Bargylia (of which three species are found in mainland Australia ) this superficial resemblance is not thought to necessarily reflect any phylogenetic proximity. L. norfolkiana is the only apterous emesine known to occur on Norfolk Island .
