Taxonomy from Gaudant 1994. The fossil cyprinid fish from the Dietrichsberg site were independently described as Palaeoleuciscus dietrichsbergensis by E. Böhme in 1993 and as P. cf. etilius by J. Gaudant in 1994. Description (Gaudant 1994, p. 225. Translated from French by oilshale): Fossil cyprinidae from Dietrichsberg are generally small fishes with standard lengths mostly between 35 and 70 mm, although the range of observed standard lengths varies from 17.5 to 85 mm. In addition, two isolated heads preserved in the Staatliches Museum für Mineralogie und Geologie zu Dresden are from individuals whose standard lengths can be estimated at 227 and 250 mm respectively (specimens S.M.M.G.D. - ThT 121 and - ThT 122). The body is relatively slender, its maximum height being generally included 4.5 to 5 times in the standard length. The head, whose length represents nearly a third (28 to 33%) of the standard length, is relatively large. The caudal fin is bilobed; its length is generally equal to 1/4 to 1/5 of the standard length.“ Line drawing (Gaudant 1994, p. 231): Identified by oilshale. References: Böhme, E.

Taxonomy from Werneburg 2021. Diagnosis from Werneburg 2021, p. 36ff: "The combination of following characters differs from most other branchiosaurids: (1) Very short maxilla, without contact to short jugal (persisting gap between maxilla and cheek up to adult stage, shared with Schoenfelderpeton). 22 teeth of maxilla are only few more than of premaxilla (16). (2) Parietals elongated and very narrow, like the width of frontals (shared with Schoenfelderpeton, Melanerpeton pusillum, Leptorophus raischi). (3) Prefrontal and postfrontal in contact (shared with Branchiosaurus). (4) Small orbita (shared with Schoenfelderpeton). (5) Wide intraorbital region (IOw/Sl about 0.29-0.37, shared with Branchiosaurus commentryensis, Apateon caducus and A. flagrifer). (6) Tooth base is relatively wide in earliest stage (shared with eryopiformes). (7) Parasphenoid with elongated basal plate and narrow cultriform process in adult stage (shared with Branchiosaurus salamandroides, Schoenfelderpeton, Leptorophus raischi). (8) Choana very wide in adult stage (shared with adult Apateon caducus). (9) Dentary with pleurodont dentition. (10) Hyobranchial skeleton of kontheri-type (shared with Branchiosaurus commentryensis, Apateon kontheri and A. pedestris). (11) Early ossification of exoccipital starting with skull length of 7 mm. Exoccipital relatively high, with a wide shaft, especially wide anteromedial ends and sculpture of longitudinal ridges. (12) Small growing species (shared with both species of Branchiosaurus, Apateon pedestris, A. flagrifer, Melanerpeton pusillum, and M. arnhardti)."
