Psittacastis trierica

Psittacastis trierica is a moth in the Depressariidae family. It was described by Meyrick in 1909. It is found in Bolivia.^[1]

The wingspan is 14–16 mm. The forewings are ochreous-brown, paler and whitish-sprinkled towards the dorsum and with an oblique triangular spot of dark fuscous suffusion on the base of the dorsum, edged with whitish suffusion. There is a straight oblique streak composed of two ochreous-whitish lines separated by grey suffusion, running from one-fifth of the costa to the middle of the dorsum. A trapezoidal white spot is found on the costa before the middle, beneath suffused with whitish-ochreous. Below this is a patch of dark grey suffusion containing a whitish-ochreous ring centred with dark fuscous. Two oblique white costal strigulae beyond the middle, the first giving rise to a very oblique bluish-leaden-metallic line dilated downwards, surrounded with orange-ferruginous suffusion, and terminating in a suffused white spot which almost reaches the terminal indentation, the second strigula finely black-edged posteriorly and soon running into this line. An oval leaden-metallic spot is found in the disc at two-thirds, followed by a spot of ochreous-white suffusion. The tornal area is indistinctly streaked longitudinally with white and blackish irroration and a white spot occupying the tornal prominence, centred with a black dot. The apical prominence is whitish-ochreous, separated by a dark fuscous spot from an inwardly oblique ochreous-whitish costal strigula, the costa between this and the preceding strigulae suffused with dark fuscous. The hindwings are grey, darker posteriorly.^[2]
