A new genus and species of Cicadellini (Hemiptera Cicadellidae Cicadellinae) from Southeastern Brazil



The Neotropical leafhopper Aurigoniella dutrai n. gen., n. sp., from Minas
Gerais State, Brazil, is described and illustrated. The new species is placed in
the nominate tribe of the subfamily Cicadellinae. The new genus can be distinguished
from other Neotropical genera of the Cicadellini by the combination of
the following features: crown produced anteriorly, its disk sculptured with punctures;
forewings without an anteapical plexus of veins; first tarsomere of hind
legs with two undifferentiated parallel rows of setae; male styles very elongate;
aedeagus short and broad, without lateral flanges; male paraphyses stalked and
symmetrical; female genital chamber with sclerotized internal sternite VIII.
Notes on the species biology, and also on some other leafhopper species from
the same region, are given. Molomea biimpressa (Signoret 1855) (Proconiini) is
recorded for the first time from Southeastern Brazil.
KEY WORDS: Cicadellidae, Cicadellinae, Neotropical region, Brazil, taxonomy, new
genus, new species.
