Remarks. This variable, pantropical species is found in many parts of the world (see Prószyński 2014 for a convenient summary). L. Koch (1879) describes and Davies & Żabka (1989) illustrate the Australian form of the species. One of the specimens examined by L. Koch, (with the correct Museum Godeffroy number) was found in the MVMA. Colour patterns of the types for both names match that of populations throughout Australia and the Pacific islands. The very large world synonymy of this species can be found in Platnick (2014), Prószyński (2014) and Richardson & Żabka (2015). The presence of a bright narrow white stripe along the base of the cephalothorax, of a membranous conductor, and the general morphology of the palp and epigyne clearly identify the Australian material as M. bivittatus. Two new, Australian junior synonyms, Menemerus acuminatus Rainbow, 1912 and Marpissa ridens Hogg, 1914, clearly showing these characteristics are established here. The types are illustrated, but not dissected due to their very fragile states.
Distribution and biology. The species has a widespread, cosmotropical, distribution. In Australia it is known from subtropical coastal regions of eastern and western Australia (Fig. 104). Extra localities in the south-west Pacific, based on material in Australian museums, are also given. As a consequence of its cosmotropical distribution, its likely IUCN Red List Category is LC.
