|Abstract:||With 206 endemic species, the phytophagous Fulgoroidea, or planthoppers,
are among the most important elements of the native Hawaiian fauna. These
principally monophagous or oligophagous insects occur in nearly all Hawaiian
terrestrial ecosystems. Species of two of the 18 planthopper families occurring
worldwide have successfully colonized and subsequently radiated in Hawai'i. Based
on collections made mainly by Perkins, Kirkaldy, Muir, Giffard, and Swezey, more
than 95% of these species were described in the first three decades of this century.
The systematics of the Hawaiian planthoppers has changed little in the past 60 yr
and is not based on any phylogenetic analyses. This paper attempts a preliminary
phylogenetic evaluation of the native Hawaiian p1anthoppers on the basis of comparative
morphology to recognize monophyletic taxa and major evolutionary lines. The
following taxa are each descendants of single colonizing species: in Cixiidae, the
Hawaiian Oliarus and Iolania species; in De1phacidae, Aloha partim, Dictyophorodelphax,
Emoloana, Leialoha + Nesothoe, Nesodryas, and at least four groups
within Nesosydne. Polyphyletic taxa are the tribe "Alohini," Aloha s.l., Nesorestias,
Nesosydne s.l., and Nothorestias. Non-Hawaiian species currently placed in Iolania,
Oliarus, Aloha, Leialoha, and Nesosydne are not closely allied to the Hawaiian taxa.
The origin of the Hawaiian planthoppers is obscure. The Hawaiian Oliarus appear
to have affinities to (North) American taxa.
