Aseptis catalina is a moth of the family Noctuidae first described by John Bernhardt Smith in 1899.
The forewings are powdery pale yellow tan with patchy contrasting darker gray markings including the filling of the reniform spot and the adjacent medial area.
The postreniform patch is large but only slightly lighter in color than the fold portion of the medial area and the filling of the lines.
The antemedial and postmedial lines are black, filled with pale cream and the postmedial line is often followed by black and white dots on the veins.
The subterminal area is pale cream, the terminal line is a series of black spots and the fringe is checkered.
