A list of the Rotifera recorded from the samples examined
is presented in Table 2. 118 taxa were identified,
four of which are new records for Thailand. The
material also included a recently described species,
Lecane superaculeata Sanoamuang & Segers (1997)
(Figure 2). One species, Lepadella quinquecostata
(Lucks), had not been recorded from Asia before. The
samples furthermore yielded a species hitherto known
from Australia only, Macrochaetus danneeli Koste
& Shiel. The rotifer species record of Thailand now
stands at 276 species. Most numerous are representatives
of the genus Lecane, with 29.7% of the species
listed, followed by species of the genera Lepadella
(8.5%), Brachionus (8.5%) and Trichocerca (6.8%).Brachionus dichotomus Shephard f. reductus Koste &
Shiel and Macrochaetus danneeli Koste & Shiel, are
Australasian species.
