本州及び北海道のハシドイやイボタ属等のモクセイ科の葉から得られており、今のところ日本固有である。前翅に2本の褐色のバンドがあることで、T. nonakaiによく似るが、後胸背楯板に鐘状感覚器を持つことで識別できる。

This species has been collected from the leaves of Oleaceae such as Syringa reticulate and Legustrum species, and is currently endemic to Japan. It is very similar to T. nonakai in having a fore wing with two dark bands, but it can be distinguished from the latter species by having the metasutum with campaniform sensilla (campaniform sensilla absent in T. nonakai).
