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)
The markings of the upperside not white but creamy.

On the tornus of the hindwings the last two submarginal black spots are clearly ringed with rusty red, more often in the female than male. Also at the apex of the forewings there are sometimes two similarly ringed spots. Described in the text under Variazioni on p.46, above the place where it is named.

The forewings show a fulvous stripe on the discocellular vein and another in the cell. Described as an aberration of Limenitis populi [Poplar Admiral] but Cabeau says that it probably occurs in camilla since he has a transitional form. Verity accepts this as being valid but actually the form is hypothetical.

The white spot in the middle of the white band of the forewings which, as a rule, is quite small, fails.

On the forewings the white costal spot in the cell is obliterated.

All the white spaces are larger than in the type form. Verity's type (from France) had the band of the hindwings 5mm wide.

The short description in Staudinger's Catalogue is somewhat vague, merely stating that the fasciae and white spots reduced. Possibly the same as ab. angustefasciata Streckfuss.

= stenotaenia Henrath.Berl.Ent.Z.(1891)1892.36.p.440.
Upperside with the bands rather narrow, not half as wide as usual. Henrath in his description of stenotaenia mentions Streckfuss as having collected the form, so presumably it is in the same as angustefasciata Streckfuss.

= semi-nigrina Frohawk.Brit.Butts.1914.p.171.pl.28.f.23.
The white bands almost obliterated or suffused. The form would seem to be transitional to ab. obliterata Shipp in which the white bands are reduced to small patches or patch, this, also, sometimes obsolete. When no white remains, the form belongs to nigrina Weymer.

= obscurior Rebel.(Selys.nom.nud.).Berge's.Schmett.1910.p.19.
Almost all black with the nervures pale. A small patch of white scales at the anal angle of the hindwings, this sometimes also being obsolete (this latter is nigrina). The form obscurior was described but not named by Selys in Ann.Soc.Ent.Belg.1.p.24.1895 as being without white bands but Rebel, who names it, says that it is transitional to nigrina and therefore shows some white, even if sparse. Rebel's description must be accepted for the name.

= nigra Cockerell.Entom.1889.22.p.54.
The upperside completely black, the white bands entirely absent. This covers the last part of the description of obliterata Shipp which says that the small white patch is sometimes also absent leaving the wings all black, nigrina having priority, only the first part of Shipp's description can apply to his obliterata.

= parva Rocci.Mem.Soc.Ent.It.1940.19.p.43.
Specimens of small dimensions.

Verity gives this name for examples of nigrina Weymer which have the underside rayed instead of the normal pattern. Specimens of nigrina typically have the underside rayed, this would seem to go with the black upperside.
