Hi Michael. So far, this sp. seems to be 'common' in small areas of suitable habitat. Around the ACT it seems to be encountered at over 1000m altitude thought I have also seen it near Wombeyan caves which is way below that. Has also been recorded at lower altitudes in TAS and VIC but usually above 600m. Bear in mind also that the cephalothorax/carapace of M. harrisi differs in all the records from VIC/TAS as compared to NSW/ACT ones!?
