This study aims to contribute to the taxonomy of the genus Gypona by providing a new synonymy, Gypona parvula Tesón, 1972 equal to Gypona nasua DeLong & Freytag, 1975. In addition, the first record from Paraná State, Southern Brazil is reported.
Based on a phylogenetic analysis using implied weighting for 59 taxa and 155 morphological characters, we provided a taxonomic revision for Acuera. The genus was recovered as polyphyletic; herein we described three new genera and 16 new species, and proposed 23 new combinations, a new status and four new synonyms for Gyponini.

Hi. I'm looking for papers that are interested in interactions between organisms to publish results (records and new species) on host-parasioid interactions (Auchenorrhyncha - Dryinidae - Encyrtidae). Could anyone suggest some options? Any free of charge? Thanks.
Hi,
I am looking for the e-mail of the current curator of the Museo de Entomologia of the Universidad Nacional de Lambayeque (Peru).
I need images of two holotypes deposited there, but I can't find a way to contact the collection.
Thanks,
Alexandre.

The manuscript of my master's dissertation is being prepared for publication. A new matrix of characters was created based on 59 terminal taxa and 155 morphological characters and 12 of the 24 species of Acuera were included. A total of 571 specimens of Acuera were examined.
The main results included:
- The genus Acuera was recovered as polyphyletic.
- The type species of the subgenera Acuera and Tortusana plus seven species of the subgenus Acuera were recovered forming a strongly supported group.
- The type species of the subgenus Parcana was recovered outside the clade comprising the type species of the subgenera Acuera and Tortusana
- Parcana will be rised to the genus level, however, three species will be transferred to the genus Curtara.
- Acuera (Parcana) gloma, and four new species were recovered forming a strongly supported group and a new genus will be proposed for this clade.
- Acuera (Parcana) rana, nine new species, and two species of Curtara were recovered forming a strongly supported group and a new genus will be proposed for this clade.
- Acuera (Acuera) inlustra will be synonimized with Hamana manifesta.
- Two new species of the subgenus Acuera will be described.
- Several new distribution records were added to species of Acuera.
- A new monotypic genus based on a new species will be described to Gyponini.
-23 new combinations will be proposed.
- A total of 16 new species are descrided.
- Four new synonyms are proposed.
- 40 new country and Brazilian states records are added to species of Acuera.
Curtara is the second largest genus of Gyponini, with 171 described species placed in 8 subgênera: Ardasoma (2 spp.); Curtara (120 spp.); Curtarana (8 spp.); Labata (3 spp.); Mysticana (3 spp.); Remarana (3 spp.); Retusana (2 spp.) and Sinchona (13 spp.), plus 17 species not designated to subgenera. The diagnosis of Curtara is only based on its type-species and need revision. Many species placed in this genus disagree with the diagnosis proposed since they have very different morphological characters compared with the type-species Curtara samera DeLong & Freytag, 1972.
Objectives:
First - Elaborate a phylogenetic hypothesis based on morphological data and test the monophiletism of Curtara and its subgenera.
Second- Elaborate a revised diagnosis for Curtara and its subgenera.
Third - To describe the new taxa found.
Fourth - Increase the known distribution of the Curtara species based on specimens deposited in the Brazilian collections.
First - Identify the iassine leafhoppers belonging to the tribes Bythoniini, Gyponini, Hoplojassini, Hyalojassini and Selenomorphini, deposited at Coleção Entomológica Pe. Jesus Santiago Moure, Universidade Federal do Paraná, Curitiba, Paraná, Brazil (DZUP).
Second - Describe the new taxa and increase the number of species recorded for the Brazilian fauna.
Third - Collect more specimens and increase the importance of the collection of Iassinae (DZUP).
