Compsolechia mniocosma is a moth of the family Gelechiidae. It was described by Edward Meyrick in 1922. It is found in Peru.[1]
The wingspan is about 15 mm. The forewings are moss green, whitish tinged towards the base, more bluish tinged towards the dorsum and termen and with a deep green dot near the base in the middle. There is a deep green rather oblique fasciate streak from the dorsum towards the base reaching more than half way across the wing, the posterior edge forming a triangular prominence on the fold, edged with white and continued as a suffused white line along the fold. The stigmata are obscurely deeper, with the discal approximated and the plical before the first discal. There is a fine white very oblique strigula from the costa at three-fourths and a streak of irregular white suffusion from the disc at three-fourths to the costa before the apex, beneath this an oval black spot almost at the apex. There are five white pre-terminal dots, between the second and third a fine black dash. The hindwings are dark fuscous, with a light grey expansible hair-pencil lying in the submedian groove.[2]
