- Comparative Mitogenomics of Andini (Hemiptera: Cixiidae) Reveals Rapid Radiation, Clarifies Relationships, and Supports Taxonomic Revision Within the Tribe Sha‐Sha Lv Thierry Bourgoin Xiao‐Ya Wang Lin Yang Yu‐Bo Zhang Xiang‐Sheng Chen Ecology and Evolution ABSTRACT Mitochondrial genomes from nine species representing three genera of the planthopper tribe Andini (Hemiptera: Cixiidae) are sequenced and analyzed, providing the first mitogenomic data for this group. The mitogenomes range from 15,415 to 15,902 bp and contain 37 typical mitochondrial genes and an A + T‐rich region, with A + T content between 73.5% and 76.0%. An inversion of trnP and trnT relative to the ancestral gene order is identified. Protein‐coding genes (PCGs) start with standard codons (ATN/GTG/TTG) and terminate with complete (TAA/TAG) or incomplete (T) stop codons. Most tRNAs display canonical cloverleaf secondary structures, except for trnS1 in Andes hemina , Parandes circinatus , and Parandes fuscus , which lacks the DHU stem. Among the 13 PCGs, cox1 shows the lowest nucleotide diversity, while nad2 shows the highest. Ka/Ks ratios indicate purifying selection, ranging from 0.0578 ( cox1 ) to 0.3080 ( nad5 ). Phylogenetic analyses, based on the present sampling, support Andini and Cixiini as sister groups forming a clade sister to Pentastirini, consistent with previous studies. Within Andini, Andixius appears sister to a clade comprising Andes and Parandes . Andes hemina clusters within Parandes , supporting its transfer to that genus as Parandes hemina (Fennah 1978) comb. nov ., based on phylogenetic and morphological evidence. Divergence‐time estimates suggest rapid diversification of Andini during the Cretaceous and Paleogene. Ancestral state reconstructions suggest that the common stalk (ScP + R + MP) represents a derived condition, whereas the ancestral state involves veins ScP + R and MP arising separately from a common point on the basal cell. 10.1002/ece3.72321 http://creativecommons.org/licenses/by/4.0/
