Specimen material from Colombo Lake (May 1905), sent by Apstein to Rousselet and now deposited in the NHM London (NHM 1917.1.1.994; NHM 1935.4.27.344), probably represents syntypic material (no types have been designated in the original publication)._x000d_
Tausz et al. (op. cit.)figure a specimen as K. tropica (Fig. 1n) which lacks the typical quadrangular posterior field, a highly characteristic and morphologically stable, but sometimes difficult to observe character of that species. Whether they actually dealt with a monospine form of Keratella valga (Ehrenberg) or this was an observational error remains unclear. [details]

Unreviewed
Alien species Keratella tropica is, like most rotifers, widely distributed. This species is mainly found in tropical and subtropical freshwater, but during summer it also thrives in temperate areas. This rotifer is a free-swimming species that tolerates brackish water. By transport in the ballast water of ships that pass through channels or via birds, the species reached Belgian regions. This species was first reported in Belgium in 1974 at Donkmeer, and at the Ghent Watersportbaan (East Flanders). At the moment, the species has colonized the upper reaches of the Scheldt river as wel as the Sea Scheldt. [details]
