Two species from Australia are placed in this genus, together with three non-Australian species whose generic relationships remain in doubt. The type species, H. australiae ( Fig. 24 View FIGURES 19 – 24 ), lives under the bark of certain Eucalyptus trees in eastern Australia ( Tree & Walter 2012), but H. platygaster is known only from a few specimens taken in the north of this continent ( Mound 2008).

Diagnosis.
