The holotype forewings of
Dominickus castnioides are about long and about wide. The wings have an overall broadly triangular shape with a rounded tip. The vein structure is very similar to that of modern Castniidae members, having an R-vein which supports the costal third of the wing. Due to the nature of the matrix in which the fossil is preserved, the
wing scales of the specimen are not distinguishable or are absent. The outline of wing margin furthest from the wing base is possibly a fringe like that found in the modern members of the family. Photographs of the specimen give possible indications of the
color pattering with the costal area, narrow at the wing base and widening out at the midpoint a dark tone. The base of the wing was possibly light colored with the tone extending along the hind margin. ==References==
