Aeologramma decolorata sp. n.

Aeologramma decolorata

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.
