Cicadomorpha

Reticycla drosopoulosi gen. et sp. n. from the Early Cretaceous of Khasurty, Buryatia is described in Hylicellidae Vietocyclinae (Cicadomorpha). The genus Jiphara Ren, 1995 from the Early Cretaceous of China is transferred from Pereboriidae to Vietocyclinae. Stigmapsylla klimaszewskii gen. et sp. n., Liadopsylla (Basicella) lautereri subgen. et sp. n. and L. (B.) loginovae sp. n. from Khasurty are described in Liadopsyllidae s. str. (Psyllomorpha). Free CuA base and nodal line are first reported in forewings of Mesozoic Psylloidea. Two species from Cretaceous ambers are transferred from Liadopsylla to Cretapsylla gen.n.: C. apedetica (Ouvrard, Burckhardt et Azar, 2010) comb.n., C. hesperia (Ouvrard et Burckhardt, 2010) comb.n. The family Malmopsyllidae is resurrected from synonymy with Liadopsyllidae and divided into Malmopsyllinae, stat. n. and Miralinae subfam. nov. (for Mirala Burckhardt et Poinar, 2020 from Burmese amber). The insect assemblage and other fossil finds from Khasurty as well as the age and paleoenvironment of this fauna are briefly discussed.

Potential insect vectors for transmission of oak leaf scorch caused by Xylella fastidiosa Wells et al., in pin and red oaks in New Jersey were surveyed by placing yellow sticky card traps in tree canopies and fogging with pyrethrin insecticide during 2002Ð2006. Thirty-seven Cicadomorpha species were collected from 20 genera in Membracidae, Cicadellidae, Aphrophoridae, and Clastop-teridae. Of the 12,880 potential vectors collected, 91.4% were Membracidae, 6.9% were Cicadellidae, and 1.7% were Aphrophoridae and Clastopteridae. Fogging collected more insect species and individuals than sticky card collections. Sticky card sampling, done more frequently and at a larger number of locations provided similar community structure information as fogging. Sticky card collections of the dominant treehopper species, Ophiderma definita Woodruff were male biased when females were gravid. O. definita populations peaked in early June, comprised 68.2% of the total collection, and were more abundant in pin oaks than red oaks. Graphocephala versuta (Say) peaked in mid-July, comprising 6.2% of the total collection. Higher Cicadomorpha populations were observed in asymptomatic oak canopies than in neighboring X. fastidiosa infected oaks. Individual insect specimens collected from oaks were subjected to a X. fastidiosa DNA assay by polymerase chain reaction ampliÞcation. The average X. fastidiosa positive rate was 13.89% for all specimens tested. Eleven treehopper species, six leafhopper species, and four spittlebug species tested DNA positive for X. fastidiosa.

Planthoppers and leafhoppers (Hemiptera: Fulgoromorpha et Cicadomorpha) of the Eastern Beskidy Mountains.
The results on studies of the fauna of Fulgoromorpha and Cicadomorpha conducted in 2013 and 2014, in the south-western part of the Eastern Beskidy Mts. are presented. A list of 64 species is given (38 are new to this zoogeographical region). Most of the species reported (69%) belong to the family Cicadellidae. Insects are analyzed in terms of their chorology, trophic relationships, humidity preferences and frequency of occurrence.
