Integrative taxonomy of Thalerosphyrus Eaton, 1881 (Ephemeroptera, Heptageniidae) in Thailand

ABSTRACT

A comprehensive revision of the genus Thalerosphyrus in Thailand is assessed. Four species are recognised: T. flowersi, T. sinuosus, T. vietnamensis and one new species, Thalerosphyrus thailandensis sp. nov., which is described here. A morphological comparison of the described species is provided. A Maximum Likelihood (ML) consensus tree based on 658 bp of the mitochondrial cytochrome oxidase I (COI) gene of five species was performed. Uncorrected p-distances strongly support the identity of these species, originally based on morphology, and show differences of 8.4–29.8% between species and 1.4–6.3% within species.
