Remarks: This species is distinguished from M. destructor only by the evenly dark colour in all individuals. The Socotran samples are of single or few specimens, and a few individuals thus coloured are present in larger M. destructor nest samples. It is hence possible that the M. mayri records from Socotra in fact refer to M. destructor , or even that these species are really synonymous. A study on more samples of different provenance will be necessary to clarify the situation. Records of M. mayri originate generally from the same geographical areas as those of M. destructor , though M. mayri has been collected more commonly in the northern Ethiopian Region.
