PA: Palaearctic; NA: Nearctic; NT: Neotropical; AT: Africotropical; OL: Oriental; AU: Australasian;
PAC: Pacific Oceanic Islands. World = total of species per taxon (one given species often occurring in
more than one zoogeographic region, the sum of the species numbers of the different regions normally
exceeds the total number of species of the family). Number in brackets = number of species confined
to one zoogeographic region only.
a Including Fredericella australiensis, Plumatella javanica, Stolella indica (occurrence/identification to
be confirmed).
b Including Stolella indica Annandale, 1909 (occurrence/identification to be confirmed).
c Not including Plumatella fruticosa (occurrence/identification to be confirmed).
d Including Lophopodella stuhlmanni Kraepelin, 1914 (doubtful species, considered as L. carteri by
Toriumi 1974) and Victorella bengalensis Annandale, 1908 (considered as synonym of V. pavida by
Wood et al. 2006).
