A new leafhopper genus of Erythroneurini (Hemiptera, Cicadellidae, Typhlocybinae) from karst area in southwestern China

ABSTRACT Guizhou is regarded as one hotspot for China's Erythroneurini diversity, from where numerous rare new species have been, or are being, described. A new genus and species of Erythroneurini from Huajiang, Guizhou, China, Anuihuajianga pyramidalis gen. et sp. nov. are described and illustrated. The new genus is characterized by subgenital plate extremely short, with long macrosetae dorsally at base, and small teeth-like setae at apex. The characteristic aedeagus shaped like two overlapping cones can also easily distinguish it from other genera. In general, this study further enriches the diversity of Erythroneurini in southwestern China.

A new species of the sharpshooter genus Onega Distant, 1908 (Hemiptera: Cicadellidae: Cicadellini) from Ecuador and Peru

ABSTRACT Onega comprises nine valid species distributed in South American countries, Bolivia, Colombia, Ecuador, Paraguay and Peru, commonly at high altitudes. The genus has as diagnostic characteristics the transition crown-frons with transversal carina; crown and superior portion of frons with concavities; pronotum wider than transocular width of head; and paraphysis, when present, as a median esclerite. The present paper describes Onega musa sp. nov., from Ecuador and Peru, which can be distinguished from other Onega species by: body mostly yellow, with brown maculae distributed on dorsum; posterior margin of male pygofer serrate, with long microsetae on the basiventral margin; aedeagus with shaft bisinuate with dorsal acute preapical process; female sternite VII with posterior margin slightly convex; and first valvula of ovipositor with 38 noncontiguous teeth. Intraspecific morphological variations are discussed.

Diversidad de cicadélidos y clastoptéridos (Hemiptera) en tres zonas productoras de café afectadas por Xylella fastidiosa Wells et al. en Costa Rica / Hemipteran diversity (Cicadellidae and Clastopteridae) in three coffee production zones affected by Xylella fastidiosa (Wells et al.) in Costa Rica

Se realizó un estudio durante los años 2002, 2003 y 2004, con el fin de determinar la composición, la abundancia, riqueza, diversidad, equidad, ocurrencia y fluctuación temporal de las especies de saltahojas en tres zonas productoras de café de Costa Rica. Se utilizaron trampas amarillas pegajosas para clasificar y cuantificar el número de saltahojas adultos durante el período de muestreo. Se encontró un total de 82.500 individuos, pertenecientes a 139 especies ubicadas dentro de nueve subfamilias. San Isidro de León Cortés presentó la mayor diversidad entre los sitios estudiados. Veinticinco especies se encontraron frecuentemente en al menos uno de los sitios muestreados, y solamente Coelidiana sp.1, Osbornellus sp.1, Scaphytopius sp.1 y Empoasca sp. se capturaron a lo largo de todo el período de estudio. La fluctuación temporal de los taxa que comprenden los principales vectores de X. fastidiosa Wells et al. mostró diferencias entre las zonas estudiadas.

A survey was conducted during 2002, 2003 and 2004 to determine the leafhopper species composition, abundance, richness, diversity, evenness, occurrence and flight activity among three coffee production zones of Costa Rica. Yellow sticky traps were used to qualify and quantify the number of aerial leafhoppers during the sampling period. A total of 82,500 individuals, belonging to 139 species within nine leafhopper subfamilies, were trapped. San Isidro de León Cortés site presented the highest diversity from the three surveyed sites. Twenty five species were frequently trapped at least in one of the studied zones, and only Coelidiana sp.1, Osbornellus sp.1, Scaphytopius sp.1 and Empoasca sp. were trapped throughout the sampling period. The flight activity of the taxa that contain the main vectors of Xylella fastidiosa Wells et al. showed differences among the sampling zones.
