The relationship of Xylomoiastrix Mikkola, 1980; Xylomoiaretinax Mikkola, 1998; and Xylomoiastangelmaieri Mikkola, 1998 is reconsidered based on 59 genitalia slides (37 males and 22 females) and 40 barcodes of adults collected from the type localities and areas in-between. Due to lack of stable morphologic differences, apart from the wing coloration of X.retinax, and low genetic distance between the three, they are considered as three subspecies of X.strix: the nominotypical one X.strixstangelmaieri stat. nov. and X.strixretinax stat. nov. Included are photographs of all specimens covering 37 adults, and 28 male and 18 female genitalia, as well as a phylogenetic tree and a map showing collecting localities.
