Checklist and comments on the jumping plant-lice (Hemiptera: Psylloidea) from Brazil
The published records of jumping plant-lice from Brazil comprise 70 named species but four are erroneous or doubtful. For one species a variety has been described with uncertain status. Seven named species records are added here based on recent collections bringing the number of valid species to 73. Four new combinations are proposed: Colophorina favis (Brown & Hodkinson) (from Euphalerus), Eur...
متن کاملVariation in sperm formation patterns in jumping plant-lice (Hemiptera: Psylloidea): a light microscopic study.
The patterns of sperm formation in sternorrhynchous jumping plant-lice are reviewed. To date information is available for 143 species belonging to 54 genera, 17 subfamilies and seven of the eight psylloid families (only Phacopteronidae is not represented). For the majority of the taxa (116 species, 39 genera, 10 subfamilies and the families Calophyidae, Carsidaridae and Liviidae) the data prese...
متن کاملMeiotic karyotypes in males of nineteen species of Psylloidea (Hemiptera) in the families Psyllidae and Triozidae.
Meiotic karyotypes in males of 16 species (assigned to 9 genera and 7 subfamilies) ofthe family Psyllidae and 3 species (assigned to 3 genera of the subfamily Triozinae) of the family Triozidae are described for the first time. The first data on the genus Ligustrinia are presented. All the species were shown to exhibit the modal karyotype for psyllids, 2n = 24 + X, except Bactericera nigricorni...
متن کاملHalf-jumping plant lice – a taxonomic revision of the distinctive psyllid genus Togepsylla Kuwayama with a reassessment of morphology (Hemiptera, Psylloidea)
Togepsyllinae is a distinctive group within Psylloidea, with its systematic status treated variously by different authors. Of the only two known genera, Togepsylla is better known and distributed in temperate and tropical East Asia. In this study, the taxonomy and morphology of Togepsylla was studied in detail. Keys to adults and fifth instar immatures of the genus are provided. Togepsylla glut...
متن کاملThe potato pest Russelliana solanicola Tuthill (Hemiptera: Psylloidea): taxonomy and host-plant patterns.
The Neotropical jumping plant-louse Russelliana solanicola Tuthill is a potato pest and a probable vector of plant pathogens. Populations morphologically similar to those found on potatoes have been collected on plants of at least ten different families, four of which have been confirmed as hosts by the presence of immatures. This suggests that R. solanicola is either a single polyphagous speci...
