GB: Lesser Madder Hawkmoth

Rethera brandti brandti O. Bang-Haas, 1937, Ent. Z., Frankf. a. M. 50: 562.

Type locality: Elburz [Alborz] Mountains, northern Iran.


BIOGEOGRAPHICAL AFFILIATION

Holarctic; western Palaearctic region. Pleistocene refuge: Monocentric -- probably Iranian or Turanoeremic refuge.


ADULT DESCRIPTION AND VARIATION

Wingspan: 42--46mm. Quite distinct, though very similar to Rethera afghanistana Daniel, 1958; it can be confused only with a small Rethera komarovi (Christoph, 1885) but may be distinguished by its abdominal segments being edged with grey and the entirely green fourth segment. There is practically no variation.
