Abstract (in english)
   The gastropod genera Hawletrochus, Holyneconcha, and Havlicekiela n.gen. derived from the uppermost part of the Třebotov Limestone (Daleje-Třebotov Formation; late Emsian, late Early Devonian) would be placed within the trochomorph group Eucochlis on the basis of their teleoconch characters. However, the study of their protoconch morphology reveals that the similarities in their teleoconch shapes are the result of shell shape convergence of unrelated gastropods. The type species of the genera Hawletrochus and Holyneconcha have an archaeogastropod-type protoconch. On the other hand, the shells of the type species of Havlicekiela n.gen. bear a typical openly coiled protoconch of perunelomorph type, placing the latter genus in the order Perunelomorpha
