Genus Klapperilepis nov.

Type species: Palmatolepis triangularis Sannemann, 1955 .

Derivation of the name: To recognise Gilbert Klapper’s contribution to understanding Devonian conodont apparatuses.

Diagnosis.—Palmatolepidids with P 1 (sp) elements with rised tip of the dorsal process and generalised appearance of the remaining elements of the apparatus.

Comparison.—The new genus differs from its Frasnian predecessors in raised platform tip of the P 1 (sp) elements, from the mid−Famennian Palmatolepis Ulrich and Bassler, 1926 in a regular distribution of denticles and dominant cusp in ramiform elements of the apparatus, from Conditolepis van den Boogard and Kuhry, 1979 in a non−derived shape of the platform, from Panderolepis Helms, 1963 in high arched M (ne) elements, and from Tripodellus Sannemann, 1955 in biramous P 2 (oz) elements of a generalised appearance.

Species included.—The type species, K. praetriangularis (Ziegler and Sandberg, 1988) , K. quadrantinodosolobata (Sannemann, 1955) , K. abnormis ( Branson and Mehl, 1934) , and K. sandbergi ( Ji and Ziegler, 1993) .
