Winnertzia solidaginis Felt, 1907 agg.

Morphological identification

Jaschhof & Jaschhof (2013, 2020b). Jaschhof & Jaschhof (2020b) treated W. solidaginis as an aggregate of several discrete species and explained the complexity of this taxonomic issue. The situation as depicted at that time persists unchanged: diagnostic characters of the genuine, originally Nearctic W. solidaginis are unclear, as are the number and morphological characteristics of its sibling species. Integrative study conducted here revealed 12 different BINs for solidaginis -like specimens from southern Germany, which however are only partly supported by clear-cut morphological distinctions: W. sp. MJDE4 (BIN BOLD:ACG6177), W. sp. MJDE6 (no CO1 sequence obtained, specimen ZSM-DIP-42307-G05); W. sp. MJDE8 (BIN BOLD:AER7056), W. sp. MJDE16 (BIN BOLD:ACF8767 and BIN BOLD:AEH9116), W. sp. MJDE19 (BIN BOLD:ACG3486), W. sp. MJDE19A (BIN BOLD:AER2285), W. sp. MJDE19B (BIN BOLD:AER2281), W. sp. MJDE19C (BIN BOLD:AER2295), W. sp. MJDE19D (BIN BOLD:ADM4238), W. sp. MJDE19E (BIN BOLD:AEX3196), W. sp. MJDE61 (BIN BOLD:ADN9678), and W. sp. MJDE62 (BIN BOLD:ACR2954 and BOLD:AEH9430).

Distribution

Germany (new record); widespread Holarctic ( Gagné & Jaschhof 2021).
