DescriptionThe tribe Darnini is a complex of morphologically diverse taxa which have been poorly studied. The tribe includes 86 species classified in 16 genera, distributed in South and Central America north through Mexico and into the southwest of the United States. Members of Darnini share the following synapomorphy: femora with two longitudinal rows of cucullate setae ventrally. Darnini is so poorly represented in past molecular and morphological works that its phylogenetic position within Membracidae, and the intergeneric relationships within the tribe remain unclear. Roy et al. (2007) reconstructed a phylogeny of Darnini based on 58 morphological characters, scored for 18 species from 14 genera. The aim of that study was to identify the evolution of mimicry strategies within Darnini. This work was not conclusive as stated by Roy et al. (2007) the tribe is in need of taxonomic work on several genera, and for broader taxonomic sampling to improve the evolutionary hypothesis.
To test the monophyly of the tribe and achieve a better understanding of the evolutionary relationships among Darnini genera, present here are the results of a phylogenetic study based on combined molecular (CO1, 28S) and morphology data (87 morphological characters). From 74 individuals housed at several international museums and representing 10 of the 16 recognized Darnini genera. The goals of this study are: 1. Reconstruct the phylogeny of the tribe Darnini; 2 Revise and redefine the genera of the Cyphotes-group. 3 Analyze the morphology of the Cyphotes group to determine the phylogenetic history of mimetic strategies. Phylogenetic analyses were performed with the concatenated dataset (1332 base alignment inferred in MAFFT), three analyses were performed Bayesian inference, maximum likelihood, and parsimony; resulting topologies indicate the following results: (1) The subfamily Darninae is recovered as monophyletic; (2) The tribe Darnini is recovered as paraphyletic; (3) At least three different lineages related with mimetic strategies were derived, or at least reversed, more than once. At the genus level, this study provides a redefinition of 5 genera and new country records. At the species level, 14 new species are described. New morphological characters are described, and the assessment and descriptions of microstructures are provide.
