Diagnosis.

This species is very similar to T. comae Schmidt, 1931, but the combination of the following characters can distinguish them: the ground colour of the forewing is whitish in T. griseata , but often yellowish in T. comae ; the surface of the wings is densely speckled with grey scales in T. griseata , but it is covered with brownish-grey speckles in T. comae ; the average wingspan is larger and sexual size dimorphism is more accentuated in T. griseata . The appendix of the sacculus of the male genitalia is on average slightly broader at base in T. griseata than that in T. comae . In the female genitalia, the ductus bursae is stouter at the anterior half in T. griseata ; the posterior appendix bursae of the ductus bursae arises at a bigger angle to the corpus bursae in T. griseata ( Kaila and Albrecht 1994; Hausmann 2004; Õunap et al. 2005).
