Описание Раковины мелкие, у многих видов имеют высоту около 5 мм. Это самый распространенный и разнообразный род Streptaxidae в Южной Африке. Большинство видов обитает на земле, в листовой подстилке, под бревнами и камнямиCole, Mary L. & Herbert, David G., 2023. Seven new narrowly endemic species of Gulella Pfeiffer, 1856 from eastern South Africa (Gastropoda, Streptaxidae) and status revision for another, European Journal of Taxonomy 900 (1), pp. 1—31Cole M. L. & Herbert D. G. 2022. Eight new species of Gulella Pfeiffer, 1856 from the south-east coast of South Africa (Gastropoda: Streptaxidae) European Journal of Taxonomy 813: 1—32. https://doi.org/10.5852/ejt.2022.813.1729. Практически полностью отсутствуют поведенческие и аутэкологические данных по Gulella s.l. В единственном серьезном поведенческом исследовании, включающем вид Gulella (как Maurennea poutrini [Germain, 1918]), Герлах (Gerlach, 1999) обнаружил, что различные подвижные мелкие наземные улитки, но не слизни, подвергались нападению и поедались. Представители рода имеют крупные гениталии (особенно пенис; редкое явление у Stylommatophora), обладают острыми пениальными крючками; при этом влагалище короткое и утонченное.
Систематика Более 400 видов и 200 подвидов или синонимов (более 1000 таксонов было описано в составе Gulella). В основном афротропический род Gulella и космополитный тропический род Huttonella рассматриваются родственными группами в составе подсемейства Ptychotrematinae из семейства Streptaxidae (Streptaxoidea, Eupulmonata).
