Auchenorrhyncha represents a group of sucking herbivores belonging to the hemipterans. They are an important component of terrestrial ecosystems, many species feed on a certain plant genus or even on one single plant species. In Poland, 514 species of Auchenorrhyncha have been recorded so far. From this number 135 species are recognized as rare, found only in a few places. Four species: Cicadetta montana (scop.), Cicadetta podolica (elchw.), Aphrophora major uhler and Aphrophora similis Leth. are endangered and should be protected. We suggest preserving xerothermic swards for Cicadetta montana and C. podolica, peatbogs and marshes for Aphrophora major and A. similis. A short morphological, ecological and chorological characteristics of these species are also given.
A new species of the family Flatidae (Sisciini) Phlebopterum tapiae sp. nov. from Madagascar is described and illustrated. Additionally, environmental affinities of newly described species are discussed. A key to all Madagascan Phlebopterum Stål species is also provided.
The paper describes a new flatid genus, Peyrierasus gen. nov., and a new species P. philippiae sp. nov. from Anosyan mountains of southeastern Madagascar. Additionally, the illustrations of the female internal genital structures are provided.
The last checklist of planthoppers and leafhoppers of Poland was published in 1990 by NAST.&CHUDZICKA and comprised 503 species (about 28% of the European fauna of this group). Compared to the first checklist from 1976, 10 species were omitted because the data on their occurrence in Poland were doubtful. These are Anaceratagallia frisia (WAGN.), Tremulicerus vitreus (F.), Micantulina micantula (ZETT..), Eurhadina untica Dlab., Euperyx curtisii FL, Zygina pruni Edw., Hardya signifer (THEN), Mocydiopsis parvicauda (RIB.), Ebarrius interstinctus (FlEB.) and Cosmotettix costalis (Fall). Moreover, 25 species were added as new to Polish fauna. Since that time a few additional taxa have been found in Poland, such as Speudotettix montanus GEB. ET SZWEDO. (species known only from southeastern Poland), Tremulicerus vitreus (F.), Eupteryx immaculatifrons (KEM.), Balclutha calamagrostis Oss.., Bugraria ocularis (M. et R.), Streptanus ogumae MATS., Cicadella lasiocarpae OSS. and Cicadula longiventris (J. SHLB.). In this paper we present three leafhopper species new to Poland, i.e. Alebra viridis Rey (earlier as a subspecies of Alebra albostriella (FALL.)), Ribautiana alces (RIB.) and Macrosteles alpinus (ZETT.). For Cosmotettix costalis (FALL.) and Micantulina micantula (ZETT.) we give first true records of the species. As a result of this the Polish fauna of planthoppers and leafhoppers contains 515 species at this time. Additionally, we describe new foundings of 9 taxa being rare: Euides basilinea (GERM..), Struebingianella lugubrina (BOH.), Cicadella lasiocarpae OSS., Ribautiana scalaris (RIB.), Arboridia ribauti (OSS.), Arboridia velata (RIB.), Elymana kozhevnikovi (ZACHV.), Doliotettix lunulatus (ZETT.) and Metalimnus formosus (BOH.). We also publish the records of Neophilaenus infumatus (HPT.) from Poland which were overlooked in NAST 1976 and take the notice of an interesting form of Anoscopus albifrons (L.) with pigmentation of the body and male copulatory organs resembling Anoscopus limicola (EDW.). For each species taxonomic, biogeographical and ecological data are also provided.
A new species of the family Flatidae Latois nigrofasciata sp. n. from Madagascar is described and illustrated.
A new genus of flatid planthoppers (Hemiptera: Fulgoromorpha: Flatidae), Lembakariagen. nov., is described for Lembakaria saintemariaesp. nov. (type species) and Lembakaria mikeaesp. nov. from the island of Madagascar. Habitus, male and female external and internal genital structures of the new species are illustrated. Lembakaria is probably endemic to Madagascar where it is known to date, only from a southern part of the island and is confined to the vegetation of Spiny Forest Ecoregion.
The paper describes a new genus of the Hemiptera: Fulgoromorpha: Flatidae, Kirkamflata gen. nov., and a new species K. socotrana sp. nov. from the Hagher Mountains in central Socotra island (Yemen). Habitus, external morphology, male and female terminalia and internal genital structures of the new species are illustrated. The new genus is similar to Latois Stål, 1866 in head morphology, wing shape and venation, male and female terminalia but differs in a rudimentary median carina on pronotum and mesonotum, longer apical cells of tegmen and details of the male reproductive parts: style, periandrium, aedeagus, as well as female ones: gonapophysis VIII and diverticulum ductus.
The Malagasy planthopper genus Paraflata is revised. To the three previously known species (P. seminigra, P. kingdomi and P. dewalschei) two new ones are added and described: P. masoalae sp. nov. and P. unispinosa sp. nov. Their distribution is discussed and a bipolar distribution (from mountain and coastal biotopes) is reported for P. dewalschei. During morphological investigations, several dead pupae of unidentified Lepidoptera Epipyropidae specimens were discovered attached to the planthopper abdomens. This is the first report for the genus Paraflata of these planthopper parasitic moths, which might be considered, in this particular interspecific interaction, rather as ectoparasites than as parasitoids.
A new monotypie genus of flatid planthoppers (Hemiptera: Fulgoromorpha: Flatidae) is described from Socotra island (Yemen): Haloflata gen. nov. for H. arthrocnemi sp. nov. (type species). Habitus, male and female external and internal genital structures of the new species are illustrated and compared with similar taxa. The new species was found in association with Arthrocnemum macrostachyum (Amaranthaceae) in coastal saltmarshes in western Socotra.
