White-tailed Ichneumon Wasp

The following wasp is a match: http://www.brisbaneinsects.com/brisbane_ichneumonwasps/BlackWhiteStriped.htm However, the taxon used should most certainly not be used, especially not in Australia and New Zealand where it seems accepted. While technically not totally illegal, the taxon represents a plant. This adds to the horror of trying to sort this taxon. More importantly, the very homotype species resides in a different accepted taxon. This species - while possibly very common in Brisbane - might be impossible to safely classify beyond Family level. Even on Subfamily level taxonomy is obscure and species density so high that it is impossible for lay people to sort through it. Even more so, when the base document [Charles C. Porter (1967): A review of the Chilean genera of the tribe Mesosteni. Studia Entomologica. 10:369-418] is not openly accessible. We need more taxonomists that clean up taxa before they create new junior synonyms. QuestaGame experts call it Achaius, a taxon that ALA does not know or represent. Maybe someone at ALA could remove Anacis and find the proper taxon for http://biocache.ala.org.au/occurrences/18b6308f-0662-4203-84ec-892dd8d60167. I suggest to use the basionym until this taxon is clarified and resolved properly. This then becomes Cryptus exul, a species described from Tasmania. Update 27/4/2017: Checking a few month later, ALA still has it as Anacis exul, GBIF silently hides the data shown previously (go uncurated open big data!). The plant genus Anacis does not show a single accepted species any longer according to Catalogue of Life. Hence, I'll follow ALA and call it Anacis exul. Update 15/9/2017: This morning I finally got a picture of this species that I believe is difficult to top. I found it in the cold early morning resting on our pineapple plant. This normally extremely shy wasp didn't mind me photographing and coming close and closer. The picture is uncropped which means that my lens and flash were about 15cm from the wasp. It must have been cold and unable or unwilling to fly. Seeing the wasp so outstretched, it dawned on me that the white antennae bands correspond to the leg bands and almost form a circle. When resting this might mimick a spider. While looking through my gallery of this species, I noticed that it might contain various similar species, i.e. wasp with red lower thorax. I will still let them grouped together.
