Diagnosis - Closely related to Gulella olkokolae ADAM, 1965 but larger and relatively broader and details of basal apertural teeth different. Description - Shell small, oblong-ellipsoid (Fig. 13), apex broadly round, with 6 visible but actually 7 whorls, apparently smooth (and shining); suture not deep; umbilical pit deep behind the shelf. Aperture subquadrate; a strong curved parietal lamella and a prominent outer lamella bearing an apical tooth and cutting off a sinus with the parietal tooth; a basal tooth to the left of the base and a columella lamella, thickened at the margin which extends across the outer edge of the peristome. Dimensions: height 3.2-3.9 mm, breadth 1.3-1.8 mm. Distribution - Tanzania, Kimboza Forest Reserve. Notes - ADAM says of his Gulella olkokolae "ombilic complètement fermé par un callus derrière le peristome". Figs 12-16. 12 = Gulella olkokolae ADAM, 1965, 13 = G. pseudolkokolae sp. n., holotype, 14 = G. eoryi sp. n., paratype, 16 = same, twisted to show outside the body whorl behind aperture (scale bar = 1 mm)
