It is found in Fujian China, Taiwan, Japan, Thailand, Philippines, and Indonesia (Sumatra).

It is however very similar in appearance and distribution to T. immissaria, but can be distinguished by differences in male and female genitalia.

[4] As with most members of the genera Thalassodes, T. intaminata has wings that are sea-green in color and semi-transparent.

Wings also exhibit very narrow, white, transverse lines.

[5] The antenna of males are usually bipectinate (comb-like) for 3/4 of the length, and filamentous at the end.
