Zoogeography of Metania 

The circumtropical biogeographic pattern of Metania  is highly disjunct with scattered records in the Neotropical, Afrotropical, Oriental, and Australian Regions. This disjunct distribution matches a Gondwanan track (see also Volkmer-Ribeiro 1976, 1990).

Metania vesparioides (Annandale, 1908) Oriental  Region (Myanmar-Burma)

Kanghyi (type loc.) at Mudon, near Moulmein, Amherst district [16 ° 16 ’N, 97 ° 44 ’W].

At the species level is possible to identify three regional groups of Metania  : a group (5 species) which is endemic to the Neotropical Region and almost exclusive of the Brazilian territory ( Table 2; Figs 1View FIGURE 1, 2View FIGURE 2); a group (3 species) which is endemic to the Afrotropical Region ( Table 2; Figs 1View FIGURE 1, 2View FIGURE 2); and a group (3 species) which is localized in a NW-SE area from Myanmar ( Burma), to Borneo, to northern Australia ( Table 2; Figs 1View FIGURE 1, 2View FIGURE 2).

The most common species are M. reticulata  and M. spinata  which are endemic to Brazil and have been found in several localities. M. spinata  is also recorded from one northern locality of Suriname. Less common are M. fittkaui  , M. kiliani  and M. subtilis  which are endemic to the Amazon area and known from only a few localities ( Muricy et al. 2011). Among the three African endemic species the most common is M. pottsi  recorded from 13 localities in the River Congo basin, and M. godeauxi  and M. rhodesiana  are only known from two localities in other central-eastern hydrographic basins ( Manconi & Pronzato 2009) ( Table 2; Figs 1View FIGURE 1, 2View FIGURE 2).

Species of the Austral-Asian group, namely M. ovogemmata  which is endemic to Australia and M. vesparioides  which is endemic to Myanmar are extremely rare and known only from the type localities, while M. vesparium  , which is endemic to Borneo, is known from the type locality and a second nearby site.

The evidently higher number of species and records in South America is probably due to the number of recent researchers working on the group and the diversity of Metania  in other regions is most likely underestimated.
