Abstract

The phylogenetic placement of the moss bugs (Insecta: Hemiptera: Coleorrhyncha) has been highly controversial. Many apparent morphological apomorphies support the close relationship between Coleorrhyncha and Heteroptera (=true bugs). However, a recent phylogenomic study strongly supported a sister group relationship between Coleorrhyncha and Auchenorrhyncha (planthoppers, leafhoppers, treehoppers, spittlebugs, and cicadas). To test these two alternative hypotheses, we examined the fore- and hindwing base structure of the only known extant macropterous species of Coleorrhyncha using binocular and confocal laser scanning microscopes and analyzed the data selected from the wing base phylogenetically. When full morphological data including the wing base characters were analyzed, the sister group relationship between Coleorrhyncha + Heteroptera was supported, agreeing with previous consensus based on morphology. In contrast, when only wing base characters were analyzed separately, the clade Coleorrhyncha + Auchenorrhyncha was recovered, in agreement with the result from the phylogenomic study. The membranous condition of the proximal median plate in the forewing was identified as a potential synapomorphy of the latter grouping, and the absence of the tegula was excluded as a potential synapomorphy of Coleorrhyncha and Heteroptera.
