This page provides access to all named aberrations of a given species and Goodson & Read (1969) is a key resource in this regard.
Description to be completed.

This section contains those aberrations that are considered new, and have yet to be formally defined.
britishbutterflyaberrations.co.uk (all aberrations)
Male. The upperside paler and brighter than normal. Later, Tutt described it as violet-blue and again hylas-like blue [syn. Polyommatus dorylas, Turquoise Blue], it would therefore seem to be a bright form of the spring generation.

Male. The upperside warm mauve. Tutt does not state the generation, by the colour these would seem to be the summer form.
Natural History Museum

Female with the upperside violet-white.
Natural History Museum

The upper and underside satiated grey. Holotype male. The female allotype and male paratype are light grey on the upperside and whitish-grey on the underside.

Female. The upperside mauve with broad black marginal and costal borders to the forewings. Hindwings fairly clear.

Female. The upperside like that of the summer generation but belonging to the spring generation, with wide black margins to the forewings, the hindwings fairly clear.

Female. Spring generation, the wings azure-blue with broad black marginal and costal borders on the forewings, the hindwings suffused.

Female. The upperside violet-white with broad marginal and costal borders. Hindwings with the costa suffused from apex to base, the outer margin spotted.
Natural History Museum

Female. An extreme form of the summer generation, the margins broad and dark. The hindwings completely dark except for some blue scaling towards the base.
Natural History Museum

The upperside of the forewings black with a blue reflection.

Male. All four wings show a discoidal spot on the upperside.
Natural History Museum

Female. The discal spot on the upperside of the forewings fails.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Female with two blackish spots on the upperside of the forewings, one between veins 2 and 3, the other between 3 and 4.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Female with three white horizontal streaks towards the apex of the forewings on the upperside. They are generally along the outer edge of the costa but sometimes lower down and well within the black margin.
Natural History Museum

Fuchs described August specimens as having the spots of the underside very small with faint traces of marginal lunules. It is generally accepted as the name for the summer generation. Ball separates the summer generation by androconial differences.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
The spots of the underside small with traces of dusky marginal lunules. This may merely represent the summer generation of the type form in which case it would have priority over ab. parvipuncta Fuchs. Not enough is known to decide, so Fuchs is given the benefit of the doubt.
Natural History Museum

The spots on the underside tending to obsolescence.

= caeca Courvoisier.Iris.1912.26.p.63.
On the underside there are no spots except the discoidals.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside the spots are well-developed but there are no marginal lunules.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside the spots are well-devoloped and are ringed with paler colour than the ground. No marginal lunules are apparent.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside the spots are well-developed, pale ringed as in ab. albocincta Tutt, but the marginal lunules are present.
Natural History Museum

On the underside of the hindwings the two lowest median spots are united to form an inverted letter ‘C’.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside of the forewings the topmost spot of the submarginal row is elongated into a black streak, the rest are well-developed but normal in shape. On the hindwings all but one small spot of the submarginal row, which is near the anal angle, are elongated into well-developed black streaks. The basal spots normal.

Blachier credits Oberthür with this form but Oberthür's specimen has quite different forewings. In Blachier's figure the forewings show only one spot on the right forewing and no spots on the left, except a tiny point near the apex. The spot on the right forewing is elongated into a streak. The hindwings are similar to Oberthür's form. If this is considered different it must be renamed.
Natural History Museum

The underside with a dark area in the centre of the forewings and a single row of spots and streaks crossing the wings. The figure shows the hindwings normally spotted, the forewings with ordinary spots, not streaks as the description suggests. The only peculiarity of this form is the dark centre on the forewings.
