Description

A. johnstoni, only differs from lycoa in not having the basal area of the hindwing uniformly rounded distally, but more or less projecting or angled in cellule 4; this character is especially pronounced on the under surface. The species is no less variable than lycoa; the light spots of the fore wing are light yellow or white and the spot in 1b is placed quite free; the forms are connected by intermediates. Palpus yellowish.

The following forms agree with one another in having the ground-colour of the fore wing above uniform black-brown without orange-yellow median band.

A. butleri Auriv. (= toruna Sm.). This species [now johnstoni subspecies] also is regarded by Eltringham as a form of johnstoni. Although the male genitalia are formed as in johnstoni it seems to me better for the present and until transitional forms have been discovered to cite butleri as a separate species, as it differs from johnstoni in the black palpus and in having the spots of the forewing quite differently developed. The spots of the forewing bright yellow; that in 4 is placed with its outer end almost as near to the distal margin as the same spot in johnstoni but is proximally long-produced and broadly united with the spot in 5; in addition the spot in 1b is joined to the one in 2 and similar spots usually occur in 3 and 1a also; hence all the light spots of the forewing are united into a yellow transverse band, which is placed behind the cell, leaves the base of cellules 2-6 free, extends from the posterior to the costal margin and has distally two large excisions (in 1b and 4); basal part of the forewing wing bright red-brown as far as the transverse band, at the base more or less blackish. Basal area of the hindwing white, yellowish or reddish; marginal band broad. German East Africa and Toro. [4]

Biology

The habitat consists of montane forests.

Adults are on wing year round.
