The wingspan is 13–17 mm. The forewings are greyish brown to brown with scattered dark brown scales and with the termen dark brown. There are black scale tufts at the middle and end of the cell, as well as at the middle of the fold. There is also a narrow yellowish-brown fascia from the costal six-sevenths to before the tornus. The hindwings are grey.

Etymology

The species name refers to the vinculum with the inner margin projecting and forming a right angle mesially and is derived from Latin rectangulus (meaning right angled).[2]

gollark: One vague idea I had which will never be implemented is something like IRC but with global email-like identity and server side history.
gollark: Matrix server software also seems to be hilariously complex and slow.
