NEOTROPICAL MONOMORIUM WANTED

     I am describing two new Monomorium from Brazil (one of them strange) and I am
taking the opportunity to make one key to all Neotropical species in the genus
(including Antichthonidris which was recently synonymized by Heterick, and including
also Nothidris). I need workers of those species not native but known in the
region as tramp species or recent invasions, or natives which aret not present in
my collection:

Monomorium carbonarium Fr. Smith
M. eveninum Forel
M. cyaneum Wheeler
M. compressum Wheeler
M. brasiliense Forel
M. subopacum Fr. Smith
M. subcoecum Emery

If possible, send me duplicates in alcohol or if dry, well mounted. Then I
can provide a necessary modern key for this important genus.

Thanks to all,
