Mehlina kielcensis (Dzik, 2006). from the K. triangularis Zone at Płucki and Jabłonna, and the K. crepida Zone at Jabłonna in the Holy Cross Mountains.

Apparatus composition of Mehlina kielcensis.

Diagnoza

Mature P₁ with relatively few (10-15) denticles, all elements of generalized morphology.

Porównanie

This is the oldest member of the Famennian lineage of Mehlina. From its probable ancestor M. irregularis, it differs in having more robust and less numerous denticles in P₁ elements; the latter character makes it different from the successor, M. robustidentata sp. n. Despite a wide population variability, samples containing these species are relatively easily distinguishable on the basis of P₁ elements. A possibly related lineage is represented by Vogelgnathus variabilis (the oldest member of the Francodinidae), different in a paedomorphic appearance and small size of elements.
