Abstract
Two new species of Tardigrada are described. Echiniscus crebraclava, new species, is similar to Echiniscus marginoporus Grigarick, Schuster & Nelson, 1983. It differs from E. marginoporus by thick clava and by different cuticular sculpture. Diphascon (Adropion) gani, new species, is characterized by having two macroplacoids, of which the second macroplacoid is elliptical and much short than the first one. It differs from D. (A.) belgicae Richters, 1911 by the elliptical second macroplacoid which is much shorter than the first one, by the first macroplacoid with constriction, by lacking microplacoid, by having septulum, and by lacking any cuticular bar near the base of claws on all legs. The new species differs from D. mariae (Mihelčič, 1951) by have eyespots, by the elliptical second macroplacoid, by lacking microplacoid and by having septulum. The new species differs from D. punctatum (Iharos, 1962) by having eyespots, by smooth cuticle, by the elliptical second macroplacoid, which is much shorter than the first one, and by having septulum. The new species differs from D. rivulare (Mihelčič, 1967) by the elliptical second macroplacoid, which is much shorter than the first one, by lacking microplacoid, and by having septulum.
