| The term Auchenorrhyncha is applied to a group
of organisms once thought to be closely related. However recent work using molecular
techniques (Sorenson et al.
1995, Campbell et al. 1995),
coupled with traditional morphological analysis (mainly Bourgoin 1986 and onwards) has
shown that, while the leafhoppers (Cicadelloidea), cicadas (Cicadoidea) and froghoppers
and spittlebugs (Cercopoidea) appear to form a monophyletic group, the planthoppers
(Fulgoroidea), are more closely related to the Heteroptera. The Suborder name
Archaeorrhyncha has been proposed for the planthoppers while the remaining
"Auchenorrhyncha" have been grouped under the Suborder Clypeorrhyncha. The other
Hemiptera Suborders are the Sternorrhyncha (aphids, scales, whiteflies, lerps and their
relatives), which is the sister group to all other Hemiptera and Prosorrhyncha
(Heteroptera + Peloridioidea). However,
Yoshizawa and Saigusa (2001)
have found support for the monophyly of the Auchenorrhyncha in the structures of the
forewing base.
Whether "Auchenorrhyncha" is accepted as a
valid group phylogenetically or not, it still retains a practical use in linking
researchers who work on planthoppers with their most closely affiliated colleagues. |
