Abstract: Microcyclops finitimus Dussart, 1984 Figs 32, 33 Diagnosis. Adult female, 580 µm in length excluding caudal setae (Figs 32A, 33A). Prosomites 4 and 5 with a finely serrulate membrane on the distal margin and at the corners (Fig. 33B, C), dorsal margin of first to third prosomites smooth. Last P1-endopod segment has a pore on the anterior surface, close to the outer margin, also a row of small spinules on the distal margin; terminal spine 1.2 times longer than the segment (Fig. 32B). Caudal ramus 4 times longer than wide (Fig. 33D). Remarks. The illustrated specimen was collected in the Tietê River, in the Três Irmãos reservoir. It has a wide distribution in South America, from Venezuela to the upper Paraná River Basin. It is more common near macrophyte banks or in the littoral zone. In the sampling sites it was relatively frequent, along with M. anceps. A complementary description of this species was provided by Gutiérrez-Aguirre and Cervantes-MartÍnez (2016).
