Linsley’s Spreadwing was described in 1960, it apparently occurs, or maybe occurred near Port Moresby, the capital of Papua New Guinea.
The species has a wingspan of about 4,4 cm; the males have distinctly shaped hindwings with a rounded flap in the anal region. [1]
It is now thought to be possibly extinct.
