Dixianus utahnus
Dixianus utahnus is a species of leafhopper in the family Cicadellidae, subfamily Deltocephalinae. The species was described by Ball in 1909 and is native to the southwestern United States. It belongs to the tribe Opsiini within the leafhopper subfamily Deltocephalinae. The specific epithet 'utahnus' refers to Utah, the type locality of the species.
Hishimonus
Hishimonus is a genus of leafhoppers (Cicadellidae: Deltocephalinae) established by Ishihara in 1953. Species in this genus are distributed across Asia, Europe, and the Middle East, with particular diversity in the Indian subcontinent. Multiple Hishimonus species are economically significant as vectors of phytoplasma diseases affecting citrus, jujube, brinjal (eggplant), and other crops. H. phycitis transmits witches'-broom disease of lime and brinjal little leaf disease; H. hamatus transmits jujube witches' broom; and H. sellatus transmits Rhus yellows. Several species have been introduced to Europe, including H. diffractus and H. hamatus.
Hishimonus sellatus
Hishimonus sellatus is a leafhopper species in the tribe Opsiini, known primarily as a significant agricultural pest and phytoplasma vector. It transmits multiple plant pathogens including the agents of Jujube Witches Broom disease, Mulberry yellow dwarf disease, and Rhus yellows. The species has been collected from mulberry fields and shows persistent transmissibility of phytoplasmas throughout its lifetime. Its mitochondrial genome has been characterized, representing the shortest mitogenome reported in Deltocephalinae at 14,690 bp.
Lycioides condalianus
Lycioides condalianus is a species of leafhopper in the family Cicadellidae, described by Ball in 1931. It belongs to the tribe Opsiini within the subfamily Deltocephalinae. The species has been documented in Arizona, with 49 observations recorded on iNaturalist. As with other members of its genus, it is presumed to feed on plant sap using piercing-sucking mouthparts.
