In other regions, there are published species of similar shape but without information about presence or absence of an umbilicus. The most similar of them is "Turbo" ferryi DU MORTIER, 1864 because of the comparable ornament [the number of spiral cords is only little more (7) than in the whorl of the same diameter in Eugclus (Eokutigclus) lokutensis SZABÓ, 1995 (5)]. However, on the basis of the considerably lower spire [H/D=1.4 while H/D=2.()-2.2 can be calculated in Li. (E.) lokutensis at the same diameter], the distinction is possible vithout other characters. A distinction from Eucyclus (Lokuticyclus) kericserensis SZABÓ, 1995 (see below) is less simple because of the similar shapes. The number of spiral cords on the (apparent) penultimate whorl gives a good basis for separation: seven in Eugclus (Eokutigclus) urkutensis SZABO, 1995 and only five on Eugclus (Eokutigclus) kericserensis. Beside this, the latter species has subregularly repeating collabral threads between the spiral cords even on the last whorl where only extremely fine growth lines are found in E. (Eokutigclus) urkutensis. On the basis of its lower spired shell and the few (four) spiral cords on the penultimate whorl, Eugclus (Eokutigclus) lokutensis is well separable. Eugclus (Eokutigclus) urkutensis is easily distinguishable from Eugclus (Lokutigclus) aff. campiliensis on the much narrower umbilicus, the higher number of spiral cords on the whorls, the density of the collabral elements and the measurements. Distribution — Úrkút, Csárdahegy (Bakony Mts), Early(?) Sinemurian.
