Remarks: Belonging to the convergens -species complex ( Kaczmarek & Michalczyk 2009a), which has an apparent global distribution ( McInnes 1994a), this species complex requires careful examination as members of this group can only be determined via subtle taxonomic details of claws morphology and other morphometric characters (e.g. Miller et al. 2005, Kaczmarek & Michalczyk 2009a). Hypsibius allisoni has disjunct Gondwanan distribution, known from New Zealand, Antarctica and South America ( McInnes 1994a).
