Morphological redescription and DNA barcoding of Monodiamesa kamora Makarchenko et Yavorskaya (Diptera: Chironomidae) from the Amur River basin (Russian Far East)

Abstract

Summary. Illustrated redescription of adult male as well as the results of DNA barcoding of Monodiamesa kamora Makarchenko et Yavorskaya in comparison with known species of the genus Monodiamesa Kieffer from the low part of Amur River basin in the Russian Far East are provided. 658 bp fragment of the mitochondrial gene cytochrome oxidase I (COI) was used for distinguishing M. kamora, M. bathyphila Kieffer and all species of subfamily Prodiamesinae available in GenBank. Interspecific distance between M. kamora and M. bathyphila ranged from 11.9 to 12.5% (mean 12.1%) and these values are sufficient to maintain the species level. Moreover, two independent groups of M. bathyphila were determined. We suppose that it is result of incorrect definition of the species.
