Apatelodes quadrata is a moth in the family Apatelodidae first described by E. Dukinfield Jones in 1908. It is found in Paraná, Brazil.[1]
The wingspan is about 41 mm. The forewings are grey, finely sprinkled with light brown. There is a double antemedial line only visible at the inner margin and costa, preceded by a white line and a large dark violaceous-brown spot on the inner margin. There is a brown postmedial line excurved beyond the cell, a brown fascia from the antemedial on the costa to the postmedial, as well as a dark violaceous-brown subapical spot, followed by minute semi hyaline spots and a larger semihyaline (almost glass-like) spot. The basal half of the hindwings is red brown in the form of a square, extending in a nearly straight line to the inner margin, and slightly excavated to the costa followed by a whitish line. The terminal area is fuscous grey.[2]
