All extant species of the planthopper genus Limois Stål (Hemiptera: Fulgoromorpha: Fulgoridae) were studied. One new species, Limois sordida sp. nov., is described and illustrated from China. Six known species are re-described and photos and illustrations of male genitalia are provided. A key to all extant species of this genus is also given.
The Afrotropical planthopper genus Centromeriana Melichar, 1912 (Hemiptera, Fulgoromorpha, Dictyopharidae, Dictyopharinae, Orthopagini) is revised. Four species are included: C. jocosa (Gerstaecker, 1895) (the type species, with confirmed records from Cameroon, Equatorial Guinea and Gabon), C. lindbergae sp. nov. (described from Sierra Leone), C. rhinoceros sp. nov. (described from Togo) and C. simplex Melichar, 1912 (so far only known from Equatorial Guinea, Bioko island). Lectotypes are designated for C. jocosa and C. simplex and both species are redescribed including habitus photographs and detailed illustrations of the male and female genitalia which are published for the first time. A key for identification of the species of Centromeriana is provided. As far as known, the genus is endemic to the (Guineo-)Congolian region of western Africa.
The following new taxa are described from the Philippines: Mioscarta nubisa Crispolon & Soulier-Perkins sp. nov., M. translucida Crispolon & Yap sp. nov. and Trigonoschema Crispolon & Soulier-Perkins gen. nov. with three new species: T. manoborum Crispolon & Soulier-Perkins sp. nov. (as type species), T. negrosensis Crispolon & Yap sp. nov and T. rubercella Crispolon &Guilbert sp. nov. Trigonoschema pallida (Lallemand, 1927) comb. nov. is transferred from Mioscarta Breddin, 1901. Descriptions of male genitalia are illustrated and keys to species of Philippine Mioscarta and Trigonoschema gen. nov. are provided. Although phylogenetic results confirm the monophyly of all genera and Trigonoschema being a distinct genus from Mioscarta, relationships between genera remain uncertain. A checklist of the genera and species of Cercopidae found in the Philippines is included.
The remarkable sharpshooter Prodigiella silvanoi gen. et sp. nov. is described and illustrated (including the external form, color, male and female terminalia) from the Atlantic Forest of southern and southeastern Brazil (states of Paraná and Rio de Janeiro). The new genus can be distinguished from other Neotropical genera of the Cicadellini by a combination of various morphological features, including an asymmetrical aedeagus with a bifid shaft and peculiar basal and apical processes and ovipositor valvula II distinctly expanded beyond basal curvature, its dorsal margin with 35–40 teeth, and ventral margin without preapical prominence. A discussion comparing Prodigiella with superficially similar taxa of the genera Macugonalia Young, 1977, Ruppeliana Young, 1977, and Versigonalia Young, 1977 is provided. The discovery of this peculiar new genus indicates that much collecting work in the remaining parts of the Atlantic Forest is clearly and urgently needed.
Basierend auf eigenen Daten und einer Literaturauswertung wird eine Übersicht über die Habitate der mitteleuropäischen Zikadenfauna gegeben. Besiedelt werden nahezu alle semiaquatischen und terrestrischen Lebenräume von Schwimmblattgürteln und Röhrichten bis hin zum Trockenrasen und vom Mineralboden bis in die Baumkronen hinauf. 61% der Arten leben permanent in der Krautschicht, rund 27% in der Baum- und Strauchschicht. Rund 11% bewohnen mehrere Straten, der Großteil davon macht einen obligaten Wechsel durch, meist vom Boden oder von der Krautschicht in die Baumschicht. Als Nährpflanzen spielen krautige Monokotyle und Gehölze mit Abstand die wichtigste Rolle. Von weitaus geringerer Bedeutung sind krautige Dikotyle und Zwergsträucher. Von jeweils nur einzelnen Zikaden-Arten werden Farnpflanzen, Gymnospermen und Pilze genutzt. Generell sind die höchsten Artenzahlen auf biomassereichen, also hochwuchsigen oder weit verbreiteten und häufigen Pflanzenarten anzutreffen. Wichtige Habitatfaktoren für einen Großteil der Arten sind Feuchte, Störung und die oftmals spezifischen Nährpflanzen. Weiterhin können Temperatur, Sonnenexposition, pH-Wert und Nährstoffgehalt des Bodens, Meereshöhe, Bodeneigenscliaften und Salinität eine Rolle spielen, sind aber z.T. miteinander korreliert. Dementsprechend gibt es besonders spezialisierte Zikadenarten in Lebensräumen, in denen extreme Verhältnisse hinsichtlich dieser Faktoren herrschen, also Ufer, Moore, Trockenrasen, Dünen, Salzwiesen und alpine Matten. In stark gestörten Lehensräumen kommen nur noch wenige eurytope, polyphage und gut flugfähige Arten mit hohem Fortpflanzungspotential vor. Eine Ausnahme hiervon bilden allerdings die regelmäßig überfüllten Kiesbänke der Alpenflüsse, die trotz intensiver Störung eine Anzahl stenotoper, monophager und monovoltiner Arten, oft mit nur eingeschränkter Flugfähigkeit, aufweisen.
Two new Brazilian sharpshooter species of the genus Tretogonia Melichar, 1926 are described and illustrated: Tretogonia diminuta sp. nov. and T. elegantula sp. nov., both from the State of Paraná. A redescription of T. dentalis Emmrich, 1988 is provided based on a male from the State of Mato Grosso do Sul. This is the first Brazilian record of T. dentalis, a species originally described from Paraguay. Photographs and line drawings are provided for the three species, as well as notes on the taxonomy and biology of the genus.
A new Brazilian leafhopper genus of the subfamily Neocoelidiinae is proposed: Takiyaella gen. nov. based on T. sexguttata (Chiamolera & Cavichioli, 2003) gen. et comb. nov. and five new species: T. anomala gen. et sp. nov., T. coelhomarquesae gen. et sp. nov., and T. daniela gen. et sp. nov. from the state of Rio de Janeiro; T. cavichiolii gen. et sp. nov. from the state of Paraná, and T. mejdalanii gen. et sp. nov. from the state of Minas Gerais. A distribution map and identification key to Takiyaella species are provided.
The planthopper family Caliscelidae (Hemiptera: Auchenorrhyncha: Fulgoromorpha) and the tribe Adenissini are recorded here for the first time from the Socotra Archipelago (Yemen). A new genus, Oceatra gen. nov., is described for two new species from Socotra Island – Oceatra litoralis gen. et sp. nov. (type species) from coastal sand dunes and salt marshes, and O. scandens gen. et sp. nov. from evergreen montane woodland and shrub communities of the Hagher mountains. Oceatra gen. nov. is similar to Perissana Metcalf, 1952 but differs in the structure of the male style and phallobase. A key to distinguish the genera of the subtribe Adenissina is provided.
Ninety percent of the Cixiidae of the Macaronesian archipelagos are endemic. Each archipelago has its own endemics reaching a total of 31 taxa. The Madeira archipelago comprises five species: Cixius madeirensis China, 1938, C. verticalis Noualhier, 1897, C. chaoensis China, 1938, Hyalesthes madeires Remane & Hoch, 1986 and H. portonoves Remane & Hoch, 1986. Good knowledge concerning taxonomy, habitat information and distribution are essential for the conservation of the biodiversity of this rich archipelago. However, due to intraspecific variation and incomplete descriptions, misidentifications of Madeira cixiids have been common. In this work, the taxonomy of this family is reviewed and ecological data based on material collected over more than forty years are presented. A new species, Cixius wollastoni sp. nov., is described. A new combination, Tachycixius chaoensis (China, 1938) comb. nov., is proposed, and a new record, Pentastiridius leporinus (Linnaeus, 1761), is reported. Lectotypes are designated for Tachycixius chaoensis and C. verticalis. The genital structures of the latter species are depicted for the first time. All species are diagnosed, described, photographed and illustrated, and an identification key for the family is provided. Thanks to this new information, Madeira together with Tenerife are the two Macaronesian islands with the highest number of endemic species of cixids.
The genus Oshaibahus El-Sonbati & Wilson gen. nov. is described with the type species Platymetopius zizyphi Bergevin, 1922. Two new species, O. kadiae El-Sonbati & Wilson gen. et sp. nov. from Sudan and O. linnavuorii El-Sonbati & Wilson gen. et sp. nov. from Iraq are described, and a new combination, Oshaibahus zizyphi (Bergevin, 1922) gen. et comb. nov. is proposed. The genus Masiripius Dlabola, 1981 (type species: Mahalana lugubris Distant, 1918) is redefined. An illustrated key to genera of the subtribe Opsiina and a key to species of Oshaibahus gen. nov. are presented to facilitate identification.
