Aeologramma decolorata
(paratype) |

8-9mm. The forewings are white, marked with black, rather than dark brown on
buff as in picatum. There are fine, irregular, angled medial and postmedial
fasciae, the former enclosing a black triangle on the costa connected to a black
patch centrally; the postmedial broadens into a black triangle on the costa
also, and there is a similar subbasal triangle. The marginal
zone contains black patches, a large one subapically and a small one subtornally.
The fasciation in picatum is less clearly defined, the pale areas
suffused with brown scales in places. The hindwings of decolorata are
medium grey.
In
the male genitalia the valve costa is angled obtusely centrally; the sacculus
extends to an obtuse angled flange subapically, and has an ampullate process at
one third. The aedeagus vesica is only finely scobinate.
