This is what i found out, about this specie:
strictly monogyn, pleometrosis founding, but queens are reduced to one, before first pupae.
polymorph ranging from 3,5-10,5mm
Mating flights are in Nov./Dec. But queens start laying egg end of feb./begin of mar.
Size of colonies can be up to 100.000 ants
Some temperature infos, depending on Messor ebeninus from libanon:
ants are active whole year. in the winter at day, in summer at night.
Ants are active from 8°C-32°C. Mostly 16°C-24°C with peak at 22°C. Lethal temperatures are 2°C-45°C
Some information about development (there was nothing said about size of worker or temperature/humidity.... so be careful with these values)
egg-larva: 40 days
larva-pupae: 27 days
pupae-imago: 14 days
and the most astonishing info: they eat seeds..

of course other stuff, too.
