Genus Guides
1Aconophorini is a tribe of treehoppers within the Membracinae, Membracidae, order Hemiptera. The tribe was established by Goding in 1892 and contains distributed in the Americas, including Mexico and Argentina. Members of this tribe possess the characteristic enlarged pronotum typical of Membracidae, though specific morphological features distinguishing Aconophorini from related tribes such as Hoplophorionini and Membracini are not detailed in available sources. The genus Aconophora is included in this tribe, with at least one (Aconophora sp.) documented from Mexico.

Identification
Aconophorini can be distinguished from the related tribe Hoplophorionini by differences in pronotal structure and tribal-level classification based on phylogenetic relationships. The tribe contains the Aconophora, which can be separated from the superficially similar genus Guayaquila (also placed in Aconophorini in some classifications) by specific pronotal and genital characteristics. Definitive identification to tribe level requires examination of tribal diagnostic characters established in taxonomic revisions, which are not summarized in general sources.

Distribution
Documented records indicate presence in Mexico (Oaxaca) and Argentina. The tribe is part of the New World fauna, consistent with the broader pattern of Membracidae diversification and radiation in the Americas following Tertiary isolation approximately 65 million years ago.
Host Associations
- Plants - phytophagousAs with all Membracidae, members feed on plant sap, though specific plant records for Aconophorini are not documented in available sources.
Ecological Role
Members contribute to phloem-feeding insect on their plants. As with other Membracidae, they likely produce honeydew that may support associated organisms, though specific mutualistic relationships for Aconophorini have not been documented.
Similar Taxa
- HoplophorioniniBoth tribes occur within the Membracinae and share the characteristic enlarged pronotum; distinguished by tribal-level morphological and phylogenetic characters.
- MembraciniAnother tribe within Membracinae with similar overall body plan; separated by pronotal structure and established tribal boundaries.
- SmiliiniTribe in Smiliinae with convergent pronotal modifications; distinguished by subfamily-level characters and tribal classification.

Taxonomic Note
The classification of within Aconophorini has been subject to revision. The genus Guayaquila is listed under Aconophorini in the source material (Goding, 1892), though some classifications may place it differently. The tribe is part of the predominantly New World Membracinae, which diversified following the separation of South America from Africa during the Tertiary period.
