Family Macrothricidae

Grimaldina brazzai Richard, 1892 . Rare species, found in a single pond (loc. 5). Littoral species. For description see Smirnov (1992) and Hollwedel et al. (2003). The species presumed to be pantropical ( Smirnov 1992), yet it is most likely a species-complex.

Guernella raphaelis Richard, 1892 . Uncommon species, found in two ponds, one lake and in a paddy field. For description see Smirnov (1992). The species is presumed pantropical ( Smirnov 1992) and is rather common in the Oriental region, yet it is most likely a species-complex.

Macrothrix spinosa King, 1853 . Uncommon in Sabah, found in two swamps, two ponds, ditch and a paddy field. For description, see Smirnov (1992) and Hollwedel et al. (2003). Species presumed to be pantropical ( Smirnov 1992), common in the Oriental region.

Macrothrix triserialis (Brady, 1896) . One of the common species, found in all types of localities except swamps. For description see Smirnov (1992) and Dumont et al. (2002). Species presumed to be pantropical ( Smirnov 1992), but identity of Neotropical and African populations with M. triserialis s. str., described from Sri Lanka, is doubted (Dumont et al. 2002).
