“…In the latter country it is mainly associated with cereal crops in the northern and central areas (Remes Lenicov & Tesón 1985;Tesón et al 1986;Remes Lenicov & Virla 1993;Remes Lenicov, Paradell et al 2006) and also with spontaneous vegetation (Paradell et al 2011). It is important to highlight that some species [Bucephalogonia xanthophis (Berg), E. obscurinervis, Graminella puncticeps Linnavuori, Stirellus picinus (Berg)], associated with rice crops are vectors of pathogens in other parts of the world, mainly of other crops with high commercial importance (Linnavuori 1959;Young 1977;Wilson & Claridge 1991).…”

We identified the species of Cicadellidae associated with rice fields from an agricultural experimental station of La Plata city, Argentina, and explored the diversity pattern of the leafhopper assemblage. Insects were obtained from rice and surrounding weeds between 2006 and 2010. Syncharina argentina (Berg) and Agalliana ensigera Oman were the most abundant species in rice and weeds, respectively. Diversity (H′), heterogeneity (D) and evenness (J) indices were estimated. There was a significant effect of crop cycle (2006 to 2010) and host plant (rice and weeds) on H′ and D, with the interaction between them being not significant. Evenness was similar in rice lots and weeds, but differed between crop cycles. The pattern of abundance of species within rice lots and weeds followed the logarithmic model. Possible explanations for this pattern are discussed. The importance of the presence of some species as vectors of plant pathogens is highlighted.

“…Remes Lenicov & Virla (1993) listaram, para a Argentina, as seguintes famílias como mais abundantes em número de espécies associadas ao cultivo do trigo: Cicadellidae (14), representada pelas subfamílias Cicadellinae (2), Bitoscopinae (4), Ledrinae (1), Deltocephalinae (5) e Typhlocybinae (2); e Delphacidae (7). Duas espécies, Syncharina argentina Berg (Cicadellinae) e X. viridis (Ledrinae), presentes no levantamento, foram observadas também no material coletado de Viamão.…”

“…Na América do Sul, assim como no Brasil, poucos trabalhos sobre a comunidade de auquenorrincos foram desenvolvidos. Remes Lenicov & Virla (1993), em um estudo inédito sobre a importância relativa dos hemípteros auquenorrincos associados ao cultivo de trigo na Argentina, citaram 21 morfoespécies, onde Delphacodes hayward Muir foi a espécie dominante durante todo o ciclo da planta.…”

“…Both male and female genitalia of the specimens were prepared for microscopic examination according to standard taxonomic techniques (Remes Lenicov & Virla 1993); the dissected parts were stored in microvials with glycerin. Scanning electron microscopy was used to illustrate some male genital structures; specimens were fi xed by soaking in formol for 48h, then dried and coated with 65-70 μm gold-palladium fi lm.…”

-Saccharosydne is the most diverse genus of the tribe Saccharosydnini. Male, female and nymphal Saccharosydne have been captured in recent collections from garlic (Allium sativum), rye (Secale cereale) and pampas grass (Cortaderia spp.) in Argentina. In this contribution, we describe and illustrate a new species S. subandina sp. nov., adding information on the geographical distribution and host plants. Saccharosydne subandina can be distinguished from its congeners by the following combination of features: uniformly light green-yellowish color with a distinctive rounded black macula on both genae; vertex 1.5x longer than wide, and projecting beyond eyes almost one half of its length; parameres divergent with internal and external angles acute; and dorsolateral angles of pygofer produced caudad. A key for species identifi cation based on male genitalia and external morphology, is provided.KEY WORDS: Fulgoromorpha, taxonomy, host plant, distributionThe Saccharosydnini (Delphacinae) includes the primarily Neotropical genera Neomalaxa Muir (one species, N. fl ava), Pseudomacrocorupha Muir (one species, P. wagneri) and Saccharosydne Kirkaldy (seven species) Asche (1985). The tribal diagnostic characteristics include the presence of seven (2+5) post-tibial distal spines, the hind wings with M and Cu fused almost all of its length and the distal anal vein not forked (convergence with most Delphacinae: Tropidocephalini).The genus Saccharosydne is distinguished mainly by the slender and elongated forms; head much narrower than pronotum, and angular in profi le; vertex extended before eyes; median carina forked on vertex; and pronotum with lateral carinae reaching posterior margin. The male terminalia with aedeagus well developed, represented by a caudally directed process and an elongate long tube coiled within pygofer anteriorly directed; pygofer subcylindrical; parameres dorsocaudally directed; the lack of processes on the anal segment and the anal style elongate. The genus is represented in the Neotropical region by six species: S. brevirostris (Muir), S. gracillis (Muir), S. ornatipennis Male, female and nymphs of Saccharosydne were recently collected from garlic (Allium sativum), rye (Secale cereale) and pampas grass (Cortaderia spp.) in Argentina. These specimens have morphological characteristics different from those of described Saccharosydne, thus we describe as a new species, S. subandina sp. nov., and provide information on its geographical distribution and biology. Given that the species of this genus are insuffi ciently studied -the original descriptions for most of them are not fully adequate, we provide an identification key based on the external morphology and male genitalia to distinguish the new species from the previously described ones. Material and MethodsAlmost all adults studied were fi eld collected on garlic in agricultural areas from Mendoza and San Juan provinces using water traps and sweep nets; others were hand captured on pampas grass and rye from several sites in Argentina. Both ma...
