Chelaner rubriceps

Distribution
This taxon was described from Australia.

Biology
Monomorium rubriceps is a species with queen polymorphism. In field colonies collected and studied in NSW always one egg-laying female was found which was an intermorph. In laboratory culture such colonies produced only workers, intermorphs (and males). After the original intermorphic queen had died the colonies reared a few alate gynomorphs in addition, from the remaining larvae. The species had been identified as Monomorium rubriceps by Brian Heterick (in litt.).
