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).
