Palaeomystella fernandesi
Palaeomystella fernandesi is a moth of the family Agonoxenidae. It is found in Atlantic rain forest of Brazil.
The length of the forewings is 4.68–6.11 mm. The forewings are covered mostly by dark-brown scales dorsally, with three interconnected white areas that form a longitudinal S-like band. There is a tenuous, U-shaped band of pale-grey scales following the contours of the tornus. The hindwings are covered in dark brown scales on both sides. Adults are thought to emerge after the winter.
The larvae feed on Tibouchina sellowiana. They create a gall on their host plant. Pupation takes place inside the gall, within a cylindrical, longitudinally arranged cocoon made of woven white silk.
