Genus Plesiommata Provancher (Hemiptera: Cicadellidae) in Argentina: first detailed description of the female genitalia and comparisons with its neotropical congeners
Get PDFPlesiommata Provancher is a sharpshooter genus with six species described, three present in the Neotropics. The morphology of the female genitalia of this genus is still poorly known. In this contribution, the female genitalia of P. mollicella (Fowler) and P. corniculata Young are described and illustrated for the first time. The vector species P. corniculata Young is recorded as new for Argentina. A key to Neotropical species including new female genital characters is presented along with updated information as new distribution records, host plant records and phytosanitary importance.Fil: Defea, Bárbara Soledad.

Comparative morphology of female genitalia of the sharpshooter genus Syncharina (Hemiptera: Cicadellidae), with notes on the generic group Cicadella
Get PDFThe sharpshooter genus Syncharina Young, 1977 includes four known species distributed in South America. Traditionally, the taxonomy of cicadellines is based mainly on male characters; however, several studies have demonstrated the existence of diagnostic features in the female genitalia. In this contribution, the female genitalia of the genus Syncharina are studied in order to add new female characters for species identification. Also, new female characters of the supposedly related genera Helochara Fitch, and Helocharina Melichar, are discovered, and their relationship with Syncharina is discussed. Additional comparative notes on Syncharina and other related genera included in the generic group Cicadella Latreille are provided. A diagnosis of the genus Syncharina, including new characters from the female genitalia, and a key to the four species included, are presented. Notes on the geographic distribution of Syncharina are provided along with new country and province records for Syncharina and Helocharina. Syncharina species can be distinguished by consistent female characters, including traits of sternite VII, the pygofer, the basal area of the first valvula and the gonoplacs. Based on ovipositor morphology, the genus Syncharina can be more clearly distinguished from Helocharina and Helochara. Little variation was seen in the ovipositors among the species in Cicadella, exposing the conservative nature of the first and the second valvulae in this group. The female genitalia provide useful characters for the taxonomy of Syncharina and their close relatives.Fil: Defea, Bárbara Soledad. Consejo Nacional de Investigaciones Científicas y Técnicas.

A new South American genus of Iassinae (Hemiptera: Cicadellidae) and additional morphological characters for two Neotropical species of Neobalinae and Nioniinae
No full textThe new iassine leafhopper genus Ana gen. nov is described, based on the type species Ana doctrix sp. nov. from Argentina, and placed in the tribe Hyalojassini. The new genus is distinguished from other Neotropical Hyalojassini genera by setose forewings, submarginal vein evanescent apically and appendix narrower than first apical cell, male pygofer with a triangular expansion turned mesad on ventral margin, lacking hooks, styles bifid basally, and female sternite VII short, with posterior margin concave. The subfamilies Neobalinae and Nioniinae are recorded for the first time from Argentina. New female morphological characters of Calliscarta fasciata (Osborn) (Neobalinae) and the male terminalia of Nionia major(Osborn) (Nioniinae) are provided. An updated key to the 12 subfamilies of Cicadellidae present in Argentina is provided.Fil: Defea, Bárbara Soledad. Consejo Nacional de Investigaciones Científicas y Técnicas.

Descriptions of immatures of the South American plant hopper, Taosa (C.) longula
Get PDFDescriptions of the immature stages of Taosa (Cuernavaca) longula Remes Lenicov (Hemiptera: Fulgoroidea: Dictyopharidae) and a key for their identification is provided for specimens collected on the water hyacinth, Eichhornia crassipes (Martius) Solms-Laubach (Commelinales: Pontederiaceae), in northeastern Argentina and Peru. Newly emerged nymphs from eggs collected in the field were reared in rearing chambers, and each stage was fixed to microscopic examination and illustration. Fifth nymphal instars can be easily recognized from congeners by the brown marked pattern coloration, shorter vertex, and the distinguishable median carina along the frons. Information on behavior and developmental time is also included.Fil: Marino, Ana Maria. Universidad Nacional de La Plata. Facultad de Ciencias Naturales y Museo. División Entomología; Argentina.

Biodiversity indicators in scientific collections: Diagnosis of the cicadellidae collection (insecta: Hemiptera) of Museo de La Plata, Argentina
Get PDFSe caracterizó la diversidad de la colección de Hemiptera Cicadellidae del Museo de La Plata utilizando los siguientes indicadores: 1) Identificación taxonómica, grado de resolución taxonómica de la colección, 2) Representatividad taxonómica y geográfica de los especímenes montados, 3) Porcentaje de especímenes con asociaciones biológicas con plantas o parasitoides. Estos indicadores fueron comparados con los del Neotrópico y con la escala del Índice de Salud de Colecciones (escalas 6, 7 y 8). Se registraron 74 géneros, 119 especies y 2796 ejemplares de Cicadellinae, Coelidiinae, Deltocephalinae, Idiocerinae, Ledrinae y Xestocephalinae para Argentina más 110 especímenes del extranjero. Para la identificación taxonómica, el material se agrupó en cuatro categorías: A- Tipo etiquetado, fichado, catalogado y publicado, B- Identificado a especie, etiquetado, fichado, con datos biológicos (escalas 6 y 7), C- Identificado a género, etiquetado, fichado y D- Identificado a subfamilia, etiquetado, fichado (escala 8). Del grupo A se encontraron 166 especímenes, el grupo B representa el 94,95% de los ejemplares (2655) (escalas 6 y 7), del grupo C el porcentaje fue de 2,18% (61 ejemplares) y del grupo D el 2,86% (80 ejemplares) (8). La representatividad taxonómica de la colección es del 40,9% a subfamilia respecto al Neotrópico. A nivel genérico, las mejor representadas fueron Xestocephalinae, Ledrinae (33,3%), Cicadellinae (18,7%) y Deltocephalinae (17,7%). A nivel específico Ledrinae (12%), Deltocephalinae (6,5%) y Cicadellinae (4,2%). Cicadellinae y Deltocephalinae representan el 96% de los ejemplares. La representatividad geográfica respecto a la Argentina fue alta 86,95 %; sólo el 12,53% de los ejemplares presentó plantas asociadas.The diversity of Cicadellidae (Hemiptera) housed in the collection of Museo de La Plata was characterized using the following indicators: 1) Taxonomic identification, degree of taxonomic resolution; 2) Taxonomic and geographic representativeness of the pinned specimens 3) Percentage of specimens associated with plants or parasitoids. These indicators were compared with available data for the Neotropical region and with The Collections Health Index (scales 6, 7 and 8). Seventy-four genera, 119 species and 2796 specimens of Cicadellinae, Coelidiinae, Deltocephalinae, Idiocerinae, Ledrinae and Xestocephalinae were recorded. To assess taxonomic identification, the specimens were grouped into four categories: A-Type material, labeled, databased, catalogued and published, B-Identified to species level, labeled and databased (scale 6 and 7 of the Collections Health Index), C-Identified to genus level, labeled and databased and, D-Identified to subfamily level, labeled and databased (8). From group A, 166 specimens were recorded, group B represented 94.95% of the total specimens studied (2655) (scales 6, 7), group C represented 2.18% (61 specimens) and D, 2.86% (80 specimens) (8). Taxonomic representativeness to subfamily level was 40.9% with respect to the Neotropics. At generic level, the subfamilies best represented were Xestocephalinae, Ledrinae (33.3%), Cicadellinae (18.7%) and Deltocephalinae (17.7%) and, to specific level, Ledrinae (12%), Deltocephalinae (6.5%) and Cicadellinae (4.2%). Cicadellinae and Deltocephalinae represent 96% of the total recorded specimens. The geographic representativeness was high 86.95% with respect to Argentina; only 12.53% of the specimens presented host plant data.Fil: Paradell, Susana Liria. Universidad Nacional de La Plata.
