Sap-feeding hemipteran insects live in associations with diverse heritable symbiotic microorganisms (bacteria and fungi) that provide essential nutrients deficient their hosts' diets. These symbionts typically reside highly specialized organs called bacteriomes (with bacterial symbionts) or mycetomes fungal symbionts). The organization of these varies between insect clades are ancestrally associated different microbes. As symbioses evolve additional complement replace the ancient associates,...

Three new species of the genus Ricanula Melichar, 1898: R. unica sp. nov., fujianensis nov. and hainanensis are described from south China. An identification key to in Chinese fauna is provided. Photographs adults illustrations genital structures also given.

Habitus, male and female external internal genital structures species are illustrated compared with similar taxa. endemic to Madagascar where it known date only one locality in Central Plateau associated tapia woodland formation.

Ornamental flowers are commonly planted in urban and suburban areas to provide foraging resources for pollinator populations. However, their role supporting broad biodiversity is not well established as previous studies have been conducted landscapes with communities that distinct from those natural systems. We observed visitation patterns five ornamental annual plant genera cultivars over multiple years at two semi-natural sites Pennsylvania understand potential diverse communities. There...

Sup-sucking hemipterans host ancient heritable microorganisms that supplement their unbalanced diet with essential nutrients and have repeatedly been complemented or replaced by other microorganisms. These symbionts need to be reliably transmitted subsequent generations through the reproductive system, often they end up using same route as most ones.

A new monotypic genus of ricaniid planthoppers (Hemiptera: Fulgoromorpha: Ricaniidae) from New Georgia Island (Solomon Islands), Kazukuru gen. nov. , is described for K. zingiberis sp. (type species). Habitus, female, external and internal genital structures the species are illustrated.

The evolutionary success of sap-feeding hemipteran insects in the suborder Auchenorrhyncha was enabled by nutritional contributions from their heritable endosymbiotic bacteria. However, symbiont diversity, functions, and origins this large insect group have not been broadly characterized using genomic tools. In particular, relationships among ancient betaproteobacterial symbionts Vidania (in Fulgoromorpha) Nasuia/Zinderia Cicadomorpha) are uncertain. Here, we genomes Sulcia three Pyrops...

Abstract A review of the cuticular and sensory metatibial metatarsal structures in cixiid planthoppers (Hemiptera: Fulgoromorpha) is proposed, depicting both their strong disparity great diversity patterns observed. Terminology definitions for these are provided. The so-called lateral teeth metatibia fact particular styloconic structures, called spiniform sensilla Cixiidae. apical metatibiotarsal non-sensory expansions, often bearing one or several chaetic ventrally, generally distributed an...

Four new genera of sub-brachypterous Ricaniidae are described from Madagascar. Globularica gen. nov. is established for a single species, diversicolorata sp. Coniunctivena four species: antsignyensis nov., C. epaulettea (type species), montuosa synavei Nasatus two sparsus species) and N. davidouvrardi Cyamosa adelinae camelouca pauliani splendens Isobium gibbosum Melichar, 1906 redescribed transferred the Issidae to Ricaniidae. Photographs, drawings maps distribution all mentioned species...

A new genus and species of the tropiduchid planthopper tribe Tropiduchini is described as Bitara augusta gen. et sp. nov. from Madang Province, Papua New Guinea. It 18th 9th known east Wallace line. another taxon with characteristic asymmetric genitalia within this tribe.

Abstract The planthopper superfamily Fulgoroidea (Hemiptera: Fulgoromorpha) currently includes more than 14 000 described species in about 21 extant families. Despite multiple studies attempted, based on morphological characters or DNA sequence data, the phylogeny of this remains unsatisfactorily resolved. Here we reconstruct phylogenetic relationship among families whole mitogenome sequences from 113 representing 17 and three as outgroups, which 41 were sequenced for study. trees...

The antennae of the shield bug Graphosoma italicum (Müller, 1766) were examined through scanning and transmission electron microscopy to reveal their general morphology, as well antennal sensilla’s distribution, size, ultrastructure dendrites function. comprise five antennomeres (one scape, two pedicels, flagellomeres). Different lengths chaetic mechanosensilla (Ch1-Ch4) exist on all antennomeres, several highly sensitive campaniform sensilla are embedded in exoskeleton measure cuticular...

A new tribe of Tropiduchidae planthoppers is described from the Baltic amber-Gedanotropidini trib.nov., with a genus and species Gedanotropis sontagae gen.et sp.nov.A key to tribes genera Eocene amber presented.Use FT-IR spectrophotometry for confirmation provenance museum material its documentation proposed.The ecoevolutionary consequences particular morphological characters taxa 'flatoidinisation syndrome' are introduced discussed.

In contrast to Cicadomorpha, in which numerous symbiotic bacteria have been identified and characterized, the symbionts of fulgoromorphans are poorly known. Here, we present results histological, ultrastructural, molecular analyses system planthopper Ommatidiotus dissimilis. Amplification, cloning, sequencing bacterial 16S RNA genes revealed that O. dissimilis is host five types bacteria. Apart from Sulcia Vidania, regarded as ancestral Fulgoromorpha, three additional belonging genera...

Abstract: A new family of so‐called ‘higher’ planthoppers, Weiwoboidae fam. nov., from the Lower Eocene Yunnan is described. monotypic genus, Weiwoboa gen. with meridiana sp. nov. also described and illustrated. The characters tegmen venation family, its evolution, supposed relationships are briefly discussed.

Ricaniidae is a relatively small planthopper family with about 69 genera and 442 species worldwide. Members of this occur throughout the warm temperate tropical regions. Some cause devastating damage to major agricultural economic plants. However, relationship between other families Fulgoroidea needs be further explored. The morphological definitions two biggest genera, Pochazia Amyot & Serville, 1843 Ricania Germar, 1818 (the type genus Ricaniidae) remain controversial. In study,...
