Records. According to Kielland (1990 , p.63), this very small species (fwl 12–20 mm ) occurs in “North-eastern Tanzania ”. Otherwise this butterfly is only known from very dry areas in Ethiopia , Somalia and Kenya (Kulal area, Kerio Valle, Archer’ s Post ( Samburu ), Athi River, Lake Baringo ?). Larsen (1996 , p.143) doubts that distorta occurs in Tanzania , the confusion apparently arising due to BMNH specimens labelled “Namanga” ( F.C. Selous , 17.ii.1916 ) which, according to N.D. Riley, most probably came from Lake Baringo, not Tanzania . There is nothing to link this butterfly with the Kilimanjaro massif.
