Type material. HOLOTYPE Australia: Tasmania: ♀, Cummings Range , 41°41'S 145°43'E, under flat rocks on summit, 30 Jan 1930, W. Hickman, AMS KS30940 GoogleMaps   . PARATYPES: Australia, Tasmania: ♀, same data as holotype, AMS KS67500 GoogleMaps   ; ♀, Mt Wellington , 42°54'S 147°14'E, near summit, 27 Oct 1990, M. Gray, C. Horseman, J. Thompson, AMS KS34436 GoogleMaps   .

Diagnosis. Closely related to H. gracilis Gardzińska   ( Gardzińska, 1996) but body much darker, cheliceral

dentition different and abdomen with contrasting light pattern. In comparison to H. minitabunda Simon (Wanless, 1988) the accessory glands are located more proximally.
