Falck & Karsholt (2026: 41) erläutern: "The species is named after its day flying habit."

3.2. Taxonomie

Falck & Karsholt (2026: 42) erklären: "We obtained a full-length DNA barcode (658 bp) from one specimen and DNA barcode fragments of 623bp, 632 bp, 634 bp from three specimens. The barcodes fall within Barcode Index Number (BIN) BOLD: AEC2486. The maximum intraspecific p-distance is 1.62 % (n=4). The nearest neighbour is an unnamed Gelechiidae species from Egypt with a 3.58 % divergence. The minimum divergence from Chrysoesthia gaditella (Staudinger, 1859) is 7.28 %."

Die Autoren merken weiterhin an: "Chrysoesthia diurnella sp. n. belongs to a complex of closely related species: C. gaditella (Staudinger, 1859), C. aletris (Walsingham, 1919), C. halymella (Amsel, 1935) and C. atriplicella (Amsel, 1939) (Huemer & Karsholt 2020, p. 124; Lepiforum 2008-2024). We consider at least C. atriplicella to be a synonym of C. gaditella, but a formal synonymization is beyond the scope of this paper. For comparison the genitalia of both sexes of C. gaditella are figured (Figures 19, 19a, 25)."
