The kinematics and jumping performance of treehoppers (Hemiptera, Auchenorrhyncha, Membracidae) were analysed from high speed images. The eight species analysed had an 11-fold range of body mass (3.8-41 mg) and a 2-fold range of body length (4.1-8.4 mm). Body shape was dominated by a prothoracic helmet that projected dorsally and posteriorly over the body, and in some species forwards to form a...

In this paper, the mutualistic relationship known as trophobiosis, which occurs convergently between ants and several groups of Hemiptera Sternorrhyncha and Auchenorrhyncha (formerly ‘Homoptera’) is reviewed. The main characteristics of ‘Homoptera’ and Formicidae which favor trophobiotic interactions, such as honeydew excretion by sapsucking insects, ant attendance and physiological needs of bo...

In the first cytogenetic study of the recently proposed family Myerslopiidae the male karyotype of Mapucheachilensis (Nielson, 1996) was analyzed using conventional chromosome staining, AgNOR- and C-bandings, and fluorescence in situ hybridization (FISH) with 18S rDNA and (TTAGG) n telomeric probes. A karyotype of 2n = 16 + XY, NOR on a medium-sized pair of autosomes, subterminal location of C-...

In this study, specimens of Membracidae (Hemiptera: Cicadormorpha) collected from Sinop (Turkey) and its surroundings in 2016-2018 were evaluated. 3 species; Centrotus cornutus (Linnaeus, 1758), Gargara genistae (Fabricius, 1775), Stictocephala bisonia Kopp et Yonke, 1977 identified the study area. Number specimens, localities, Turkey zoogeographical distribution are given. Identified species f...
