Wailuku Pug Moth (Eupithecia dryinombra)

The Wailuku Pug Moth was described in 1899, it is known only from the male type specimen.

The species reaches a wingspan of about 1,7 cm, it is rather pale and narrow-winged, there are obscure medial bands on its forewings that are marked by a series of short, disconnected longitudinal dashes.

The species inhabited the native rain forest above a place named Wailuku on the island of Moloka’i, Hawaiian Islands, a habitat that is now heavily degraded by introduced mammalian herbivores. 

The Wailuku Pug Moth was never recorded since its description and is likely extinct. [1][2]
