I have recently acquired a copy of "Revision of the Australian Scorpion-fly Genus Harpobittacus (Mecoptera : Bittacidae) Lambkin 1994, with thanks to Kevin J. Lambkin, @christopherburwell and @sdoug7405 and original prompting by @matttudor. Other people who may be interested: @grigorenko @ellurasanctuary @thebeachcomber @rover-rod - if anybody wants a copy I can email it to you (send me a private message if you don't want your email public).

I am working through this now to particularly see the distinction between Harpobittacus australis and Harpobittacus nigriceps and to likely correct many of my past identifications...

The most important section should be the Key, which I have copied out here:

From distribution maps

• H. australis distributed through much of Victoria (excluding northern & north-western inland), Tasmania and along the coast of South Australia to the Eyre Peninsula and through the mountainous regions of NSW to the Qld border
• H. christine Bunya/Towoomba regions
• H. albatus costal regions from Wollongong to Rockhampton (plus a couple of records a bit more inland and one in Townsville)
• H. septentrionis Mackay to Cairns
• H. scheibeli southern Qld quite far inland and just into northern NSW
• H. nigriceps SE corner of SA along coast then broadening range through central Victoria into west Gippsland from Wilsons Prom and along northern foothills just into NSW.
• H. tillyardi coastal NSW and coastal southern Qld
• H. rubricatus southern inland Qld, inland NSW into NW Vic and through middle third of SA to top of Eyre Pen.
