Abstract:
195 species, including preservation artifacts which were identified to genus level, were found in
18 samples collected in 12 different waters of Ecuador during September 1988. 178 belong to the order
Monogononta and 17 to the order Bdelloidea (Digononta). The highest diversity was in the Amazonian
lowland with 161 species; in waters of the pacific coastal area we found 81 species and in the Andes
only 63. The poorest Rotifer fauna was in Lake Mojanda in the high mountain region at 3,700 m above
sea-level with only 9 species.
Some remarks were made on 12 particular species: Collotheca tenuilobata, Floscularia melicerta,
Hexarthra intermedia brasiliensis, H. mira, Manfredium eudactylotum, Monommata grandis, Octotrocha
speciosa, Ptygura elsteri, Henoceros falcatus, Macrotrachela multispinosa and Mniobia russeola.
