Typhlocybini

Kirschbaum, 1868

Genus Guides

Typhlocybini is a tribe of leafhoppers within the Typhlocybinae (Cicadellidae), established by Kirschbaum in 1868. Phylogenetic analysis based on complete mitochondrial has confirmed that Zyginellini should be treated as a junior synonym, as it is with respect to Typhlocybini. The tribe includes at least 31 in China alone, with notable generic complexes including Farynala and Linnavuoriana. Members are characterized by distinct wing venation patterns, including a third forewing and specific hind wing venation features.

Identification

Typhlocybini can be distinguished from related tribes by wing venation characters: forewing with third ; hind wing with RP and MA separate throughout their length and connected by a cross , lacking a submarginal vein. The tribe Prodorsostyla exhibits a significantly elongated style, a notable morphological specialization within the tribe.

Habitat

Collection records indicate montane at elevations of 730–1055 m in nature reserves. Specific localities include bamboo-associated habitats and collections from Cinnamomum camphora (camphor tree).

Distribution

Documented from China (Guangxi, Hainan, Yunnan, Sichuan), with 31 recorded from China. Broader distribution likely extends beyond China given the tribe's established taxonomic status, but specific non-Chinese records are not detailed in available sources.

Diet

Phytophagous. Phloem-feeding inferred from .

Host Associations

Cinnamomum camphora - Explicitly documented for Prodorsostyla jinzishiensis
Bamboo - Inferred from original Mohunia placement in Mukariini, a bamboo-feeding tribe; Ommatocyba biguttata collections from bamboo

Ecological Role
