Abstract
In 1990 the second author made a second expedition to Ecuador, where, together with a small team,
studied waters in the three regions of this country: Oriente, Sierra and Costa.
Beside geographical studies, the group had taken physical and chemical data of wateranalyses in running
and still waters.
To complete our knowledge of the rotatoria fauna, samples of different visited streams, lakes and swamps
were collected.
257 species (including preservation artifacts) were identified by the first author. Now, including the results
of the first investigation of 1988, 300 rotifers are known from Ecuador.
Some remarks are made of Floscularia melicerta, Lecane (s. str,) calcaria, L. murrayi, L. pusilla,
Lepadella quinquecostata, Monommata phoxa, Platyias leloupi and P. quadricornis brevispinus.
As nov. spec. and nov. subspec. are described: Aspelta ecuadoriensis, Cephalodella tincaformis, Lecane
eupsammophila, Lepadella elongata; Lepadella latusinus striata.
The diversity of Ecuadorian rotifer species as a whole (in its entirety) has surely been recorded in its
essential features with these two present studies. We do not know any other aquatic group of invertebrates in
Ecuador of which samples were taken in such a number of different types of water and which simultaneously
was evaluated taxonomically and systematically by means of ecological data.
