description: <i>Difflugia alekperovi</i> sp. n. (fig. 4–7) Type specimens. Holotype on slides N L–14 and paratypes on slides N L–15–17, collection of Protistology Laboratory of the Institute of Zoology, National Academy of Sciences, Baku city, Azerbaijan. T y p e l o c a t i o n. In the sediments of small forest water reservoir near Azfilial settlement (38°40ʹ56.5&amp;dblac; N; 48°46ʹ58.5&amp;dblac; E; 51 m a. s. l.) and sediments of Khanbulanchay water reservoir (38°40ʹ10.99&amp;dblac; N; 48°46ʹ05.87&amp;dblac; E; 73 m a. s. l.) (Lenkoran District, Azerbaijan). D e s c r i p t i o n. The shell in water samples from light- to dark-brown, in glycerol discolored to transparent. The cell shape is slightly ovoid, almost rounded. Shell length 86–188 µm, width 81–162 µm Shell surface is rough and covered with irregularly-shaped siliceous plate particles and pieces of diatoms. Terminally located aperture is very small (11–25 µm), circular, not surrounded with particles. Morphological and morphometrical characteristics of <i>D. alekperovi</i> sp.n. are shown in figures 4–7 and table 1. Living cells not observed. Very rare species, we found it only in autumn and spring. D i a g n o s i s. The shell is almost rounded, with very small rounded aperture. <i>Difflugia alekperovi</i> sp.n. is similar to <i>Difflugia subaequalis</i> Penard, 1910, <i>D.lithoplites</i> Penard, 1902, <i>D. lebes sphaerica</i> Gauthier-Lièvre et Thomas, 1958, <i>D. lebes masurica</i> Schönborn, 1965, <i>D.geosphaira</i> Ogden, 1991, <i>D.globulosa</i> Dujardin,1837, <i>D. globularis</i> Wallich, 1864, <i>D.minuta</i> var. <i>grandis</i> Gauthier-Lièvre et Thomas, 1958, but differs: from <i>Difflugia subaequalis</i> by more rounded shell, smaller aperture, different shell covering; from <i>D. lithoplites</i> by shape and size of aperture and different shell covering; from <i>D. lebes sphaerica</i> and <i>D. lebes masurica</i> by more rounded shell, aperture size and shell covering; from <i>D. geosphaira by</i> more rounded shell, absence of collar, by aperture shape and size; from <i>D. globulosa</i> by more rounded shell, smaller size of the aperture; different shell covering; from <i>D. globularis</i> by more rounded shell, much smaller size of the aperture, different shell covering; from <i>D. minuta</i> var. <i>grandis</i> by more rounded shell form and different shell covering. Diagnostic characters of <i>Difflugia</i> species are given in table 2 and on fig. 8–28. E t y m o l o g y. The species was named in honor of the famous Azerbaijanian. protistologist, Prof. Ilham Alekperov.
