Camptomyia multinoda

Camptomyia multinoda (Felt, 1908) agg. Morphological identification Jaschhof & Jaschhof (2013). DNA barcode CO1 sequences (651‒696bp) of the 73 specimens listed below were assigned to five different BINs, namely BOLD:AEW6793 (one specimen), BOLD:AER0301 (eight), BOLD:AEY2389 (one), BOLD:AEY8233 (five), and BOLD:ACU9836 (58). Search on BOLD’s BIN Database retrieved a further match for BOLD:ACU9836, as Cecidomyiidae sp. from Canada (accessed 26 Aug. 2023). The occurrence of this BIN in North America might indicate that this is the genuine C. multinoda, a species originally described from Illinois, USA (Felt 1908). A further match was also retrieved for BOLD:AEW6793, as Cecidomyiidae sp. from Norway (accessed 26 Aug. 2023). My reexamination of the DNA barcoded specimens from Germany revealed slight morphological distinctions in support of the genetic clustering found here, which concern the gonostylus, the parameres, and the ninth tergite. However, individual variation, which no doubt occurs in these structures too, were found to blur intercluster distinctions. Also, there is the disturbing fact that the specimens assigned here to five different clusters come from the same site. One wonders what picture of genetic variation DNA barcoding would draw once multiple samples of morphotypical C. multinoda from different parts of the vast distribution area were subjected to analysis. For the time being I consider C. multinoda an aggregate species in need of further research.
