So I have had these queens for a while now, but can't find an ID. Any ideas?

 

Location: China, Hong Kong

Where it was found: At school next to lamp (also where the golden tree ants are found)

Area: On mountain, quite heavily forested

Size: Queen is about 7mm, worker is 4mm

Description:

(queen) Redish black head, Brown, black and orange thorax, Orange and silver (shiny silver) bands on gaster, short hairs

(worker) Brownish black, shiny, short hairs, yellowish legs

Wow! Those are awesome. I love the silver bands. Wonder how they look when the ants are gorged on food

These are not Colobopsis. They are Camponotus. As for the species, I cannot find a single species that matches this. They are most likely in the subgenus Myrmentoma, but I'm not for certain with that assumption.

Why are they not Colobopsis? The face is truncated.
Colonies:
Nylanderia vividula
Pheidole navigans
Camponotus hyatti
Founding queens: Brachymyrmex patagonicus, Solenopsis xyloni, Lasius cf. niger, Solenopsis molesta, Temnothorax cf. caguatan, Formica argentea, Camponotus vicinus, Pogonomyrmex californicus, and Myrmica cf. tahoensis.

I agree, they do appear to be Colobopsis, but take what I say with a grain of salt.
5 queen Temnothorax ambiguus (founding)
11 queen Temnothorax curvispinosus (founding)
1 queen Colobopsis mississippiensis (founding)
1 queen Colobopsis impressa (founding)
1 queen Lasius interjectus (with 30 host workers)
x3 1 queen Camponotus subbarbatus (founding)
1 queen Strumigebys pilinasis (colony of about 30 workers)
1 queen Ponera pennsylvanica (founding)
x2 1 queen Pheidole bicarinata (founding)
1 queen Temnothorax curvispinosus (~170 workers) ... also have 2 termite colonies.

He's in Hong Kong. Would be surprised if it was a new species. I assume the ants there are fairly well recorded

Upon closer examination of the nanitic, the mesosoma matches that of a species of Camponotus, and the queens do appear to have the basic body shape of a Camponotus in the subgenus Myrmentoma. If they were Colobopsis, which is unlikely, the closest match would be Colobopsis equus, but that is unlikely as Colobopsis equus has a different head shape, lower petiole, and a wide variety of other features that rule out this species.

I checked the key for Colobopsis species in the area (there are only two on record) and I think this is fairly good judgement

I stand corrected, so no one have any ideas on a possible speices?
