Type material.

Holotype, ♂, Tanzania, Morogoro, Morogoro Town, 11.iv.1992 (Aarvik) (gen. slide 2380, O. Bidzilya) (MNHO).

Diagnosis.

The new species remotely resembles externally Aphanostola morogorensis sp. n., but is smaller, the forewings are broader and the black spot on ¾ of dorsum is indistinct. The male genitalia somewhat resemble those of Aphanostola brandbergensis sp. n., but differ in the short, rounded uncus, longer saccus, slenderer gnathos and the phallus without apical tooth.
