2.1. Etymologie (Namenserklärung))
Zhang et al. (2025: 69) erklärten: "In Greek, ἀγκών (ankōn) means elbow, bend, or corner. The name is given for an L-shaped band of forewing apical spots and is a noun in apposition."
2.2. Taxonomie und Faunistik
Evans (1952: 82) beschrieb das Taxon als "Ridens philistus ssp. philia" (Typenfundort "Colombia, Cauca, Juntas"), das er von "Ridens philistus ssp. philistus" unterschied. Erst Zhang et al. (2025: 68-69) klärten auf, dass Evans' "Ridens philistus ssp. philistus" gar nicht mit Hopffers "Eudamus philistus" identisch war, sondern eine noch unbeschriebene Art meinte: Ridens ankon Grishin, 2025. Sie erläutern unter der Überschrift "Ridens ankon Grishin, new species: "This is the species that Evans (1952) misidentified as Ridens philistus (Hopffer, 1874) (type locality in Peru, a tailed species, see above), and therefore keys to it (C.12.5(b)) in Evans (1952). As Evans suggested, this new species is indeed closely related to Ridens philia Evans, 1952, new status (type locality in Colombia) (Fig. 5, COI barcode difference of 1.7% (11 bp)), but differs from it and other relatives by the absence of hindwing tails (present in R. philistus), the hyaline spot in the cell M3-CuA1 extending basad till the origin of the vein CuA1, and the prominently developed subapical band of six spots (weakly expressed, some spots absent in R. philia) that is strongly bent in the middle at a nearly right angle in an elbow-like fashion, but not lamed-shaped (ל) as in R. philistus. This species is not cryptic and can be recognized by its phenotype." Als Typenlokalität nannten sie "Ecuador: Chimborazo, Atzatapungu, elevation 4100 m" und als Verbreitungsagebiet: "Currently known from Ecuador (the holotype) and Peru (per Evans (1952), specimens not included in the type series)."
