1. Genus
Atta 'At'
Acromyrmex 'Ac'
2. Species
First 3 letters of bninomial. ie Atta cephalotes would be At. cep.
3. Developmental Stage
Colony consists of 'mated queen only' 'mqo'
Colony consists of mated queen and eggs / pupa(e) (has brood) 'mqb'
Colony has 1-5 workers 'mq5'
Colony has up to 50 workers 'mq50'
Colony has up to 500 workers 'mq500'
Colony has more than 500 workers 'mq500+'
4. Fungal Size
Fungus is absent 'F0'
Fungus is less than 1cm diameter 'F1'
Fungus is 1-5cm diameter '1F5'
Fungus is 5-15cm '5F15'
Fungus is bigger than 15cm 'F15+'
5. Number of fungus gardens
1(size of fungus garden)
2(size of first fungus garden)(size of second fungus garden)
3(size of first fungus garden)(size of second fungus garden)(size of third fungus garden)
etc, etc
6. Health of fungus garden
fungus is uniformly white. 'W'
fungus is mainly yellow 'Y'
fungus is mainly grey / dark grey (or green) 'G'
7. Castes present
minims only 'min'
up to small workersize 'smw'
up to large foragers 'lgw'
majors present 'maj'
So

would be
At.cep.mq50.smw.1(1F5).G
which reads Atta cephalotes, mated queen, up to 50 small workers, one fungus garden which is bigger than 1cm, less than 5 cm, Grey / green in colour.
What do you think. If we got used to this it would mean a lot of information about each colony we talk about could be passed over in relatively little description.
