Diagnosis: The single female specimen lacks a distinctive diagnostic feature; see Remarks.

Description: Head: Scales generally brown with light brown near apex. Antenna [mostly broken] with a few short, piliform cilia. Labial palpus mottled brown and light brown; third segment ca. 0.8x length of second. Thorax: Brown. Forewing length 10 mm; forewing ground color mottled light whitish-brown and brown; discal area clouded with poorly defined blackish spots; spots on distal half of costa and along termen at vein endings not visible [possibly rubbed]. Hindwing very light brown; fringe light whitish-brown. Abdomen: Mounted on slide. Female genitalia typical for genus; signum long.

Food plants: Unknown.

Remarks: The holotype is the only known specimen. It may be a worn T. usitata , but the poor condition of the specimen makes an accurate determination impossible.
