Winnertzia xylostei Mamaev, 1963 agg.

Morphological identification

Jaschhof & Jaschhof (2020b). Winnertzia xylostei as treated by Jaschhof & Jaschhof (2013) was subsequently shown to be an aggregate of three morphotypes (Jaschhof & Jaschhof 2020b). The diagnostic characters of the genuine W. xylostei, a species described by Mamaev (1963), have yet to be specified.

DNA barcode

CO1 sequences (651‒725bp) obtained of the five specimens detailed below were allocated to two BINs: BOLD:ACC8240 (ZSM-DIP-42307-H10, ZSM-DIP-42477-G03) and BOLD:AEA0752 (ZSM-DIP-42307-G09, ZSM-DIP-42307-H03, ZSM-DIP-42307-H05). All five specimens belong to the same morphotype, referred to as “ xylostei B” by Jaschhof & Jaschhof (2020b), and four of them were found in the same Malaise trap sample. Search on BOLDʼs BIN Database retrieved seven matches for BOLD:ACC8240, all as Cecidomyiidae sp. from Canada (accessed 26 Aug. 2023).
