Diagnoza Shell slender 2.3 times as high as broad. Protoconch 2 whorls rounded and ornamented with pustules. Demarcation between protoconch and teleoconch with thickened outer lip. Teleoconch whorls rounded and ornamented with strong axial ribs and weak spiral lirae.
Porównanie The protoconch is similar to that of Diatrypesis kurushini (but the latter is more dome-shaped) and similar to certain rissoinid protoconchs. The teleoconch ornamentation is also a little similar to that of the rissoinids, but the pattern of ornamentation can be observed in many other groups (e.g., some pseudozygopleurids). Dzikella also resembles the Late Cretaceous epitoniid genus Aciculiscala, especially Aciculiscala coffea Dockery, 1993 but the former has a smooth protoconch with a thickened outer lip.
