Classification
Though this genus was first proposed long ago, for much of the time Thereus was included in the "wastebin genus" Thecla. However, the two genera are not particularly close relatives among their subfamily. In recent times, it has been proposed to remove several species from Thereus to smaller or even monotypic genera. While this might be warranted in some cases, it is not followed here pending more thorough study.[1]
The junior synonyms of Thereus are thus:[1]
- Molus Hübner, [1819]
- Noreena K.Johnson[verification needed], MacPherson & Ingraham, 1986
- Pedusa D'Abrera, 2001 (may be nomen nudum)
- Solanorum Johnson, 1992
- Timokla Johnson[verification needed], Kruse & Kroenlein, 1997
