Morphology lies: a case-in-point with a new non-biting midge species from Oriental China (Diptera, Chironomidae)
Morphological traits are generally indicative of specific taxa, and particularly function as keys in taxonomy and species delimitation. In this study, a non-biting midge species with an Einfeldia-like superior volsella makes it hard to accurately determined based on its morphological characteristics. Molecular genes of two ribosomal genes and three protein-encoding genes were compiled to construct a related genera phylogeny and to address the taxonomic issues. Phylogenetic inference clearly supports the undetermined species as belonging to Kiefferulus. Therefore, a new species classified in the genus Kiefferulus is described and figured as an adult male from Oriental China. The species could be easily distinguished from other species in having an Einfeldia-like superior volsella and a triangular tergite IX.
