just caught the same abb. a few weeks ago. My specimen is just like yours (as I can tell) a male specimen. In the Cockayne collection I couldn't find a name for this form with a male specimen. The most resemblance is found with the female abb. lunulata.
On the internet I also found some pictures of similar male specimens with red markings.
If you find the correct name for this form you would make me also happy...

Can we see the verso of this specimen ?
Thomas, I don't see why it would be an ab. lunata.

Hi Thomas
Your male does look the same as mine. Do you have a name for this abb.

Lol on the verso you have an uncommon ab. i-nigrum. Now we have to find for the recto. The friend of nomad must be able to help us. I don't find it in the Monograph of the British aberrations of the Chalk-Hill blue butterfly (Bright and Leeds) that I have checked today |

Hopefully will have some information on Steve's abb in the near future.

My copy of Bright and Leeds is packed up so I can't be certain.
But this looks like ab.divisa with the black outer f/w border divided in two by white. I think it is in the group of abs that run towards fowleri.
Anybody with a copy please check.

Hi Steve,
I have checked my drawer of male Chalkhill abs, and it is a definately a male minor, which is quite a bit smaller than normal, but larger than minutissima.
The top is ab' divisa, and the underside is ab' arcuata.
Anyone can correct me if you have any further info.

What is the difference between arcuata and i-nigrum? Or are these 2 the same?
Still a big questionmark about the orange dots... I have found a lot of pictures on the net with males with orange markings but never a name for the aberration... I hope someone knows this because I am still waiting to name my specimen too...

I think I can answer some of the above.
I-nigrum and arcuata are basically different expressions of the same aberration.
When the two basal spots in cell 1b are joined by a straight bar with blunt edges, then it is I-nigrum, when they are joined by a line that appears curved then it is arcuata.
Occasionally the corresponding spots in cell 1a follow suite, these joins can also be straight or curved. Ending with silly names such as bi-I-nigrum, I-nigrum-arcuata, dex-I-nigrum-sinis-arcuata-I-nigrum etc. etc.
I am sure that somebody with access to Bright and Leeds will be able to run down the orange spots on the h/w verso. It is a named aberration, but I cant remember what it is called.
The specimen is also definately an ab minor. However I don't usually bother with this type of name; prefer to call then underfeditis or starvedus.

Ok I checked again my Bright & Leeds for oosteve's specimen
Recto :
- the 3 orange lunules : ab. trisuavis (rare).
- the white markings into the black outer border : ab. divisa (fairly common)
Verso :
- ab. i-nigrum (common)
Congrats for having found this unique specimen !
