03E09278FFDBFFEFFF0CFC05A21E180A.taxon	materials_examined	Type — Căpeni (Köpecz), Neogene fossil deposits in Romania (accession no. BP 88, leg. J. Pantocsek Slide BP 2240, Pantocsek Collection, BP, Lectotype (designated here) = Fig. 2; Slide MKNDC 006290 / A, isolectotype). Observations: — In this study population, the valves had wider range of morphological features than given by Pantocsek: length: 95 – 100 µm vs. 58.5 – 121.0 µm; breadth: 35 – 42 µm vs. 32.0 – 54.5 µm; striae density: 7 – 8 in 10 µm vs. 6 – 7 in 10 µm; areolae density: 5 in 10 µm vs. 4 in 10 µm. Navicula budayana was illustrated by Pantocsek (1892) but the written description was provided later (Pantocsek 1905) giving size range of 95 – 100 µm in length and 35 – 42 µm in width. Hustedt (1937) formally transferred this species into the genus Diploneis. Later, Jurilj (1954) reported extant population of D. budayana from Lake Ohrid. However, detailed LM and SEM analyses showed several morphological differences between Lake Ohrid and Köpecz populations (Jovanovska et al. 2013). Based on differences in the valve axial area (wide lanceolate with slightly expanded central area vs. narrow lanceolate with slightly expanded central area) and the striae structure (biseriate vs. single transapical slit), the species from Lake Ohrid was distinguished and described as D. parabudyana (Jovanovska et al. 2013, figs 1 – 9, 12, 13). Consequently D. budayana has a limited distribution in the Romanian lacustrine fossil deposits. With observations on the type material, D. budyana could easily be mistaken with D. hilarula (Pantocsek) Mills (1934: 618) = Navicula hilarula Pantocsek (1892, fig. 15: 230). However for any given length, specimens of D. hilarula have broader apices and more linear valve margins. Additionally, the most distinguishing feature of D. hilarula is the wide hyaline area position along the longitudinal canal. This hyaline area has not been documented in D. budayana. Stratigraphic remarks: — Neogene (Middle Miocene - Late Miocene); the intra - Carpathian area became isolated only during the Late Miocene, when the tectonic compression reached to the climax during the Late Sarmatian (~ 11 MY). As a result there was a collision between the “ Transylvanian block ” and east European Continental plate (Krések & Filipescu 2005). In this realm originated Lake Pannon, which transformed from a large brackish to a freshwater lake (Magyar et al. 1999). As a part of the Lake Pannon, the Transylvanian Basin represented an isolated basin during the Late Miocene, as indicated by endemic faunas (Müller et al. 1999). These palaeoecological conditions determined the development of diverse and rich non - marine benthic diatom flora. During the Pliocene the evolution of Baraolt - Brasov Depression could be a remote bay of the Black Sea and having higher salinity due to evaporation (Krstić et al. 2012). Until now, there has not been enough palaeontological data for more precise chronostratigraphic determination.	en	Jovanovska, Elena, Buczkó, Krisztina, Ognjanova-Rumenova, Nadja G., Nakov, Teofil, Levkov, Zlatko (2013): Identity and typification of Diploneis ostracodarum, Diploneis budayana and Diploneis praeclara (Bacillariophyta).

03E09278FFDCFFECFF0CFDFCA3B4180A.taxon	materials_examined	Type: — Căpeni (Köpecz), Neogene fossil deposits in Romania (accession no. BP 88, leg. J. Pantocsek, slide BP 2241, Pantocsek Collection, BP, Lectotype (designated here) = Fig. 14; Slide MKNDC 006290 / B, isolectoype). Observations: — Jurilj (1954) observed an extant population of D. ostracodarum in Lake Ohrid. In the same publication, he informally proposed transfer to the genus Diploneis based on his discussion of its morphological features (Jurilj 1954). Recently, Jovanovska et al. (2013) provided the appropriate formal transfer of D. ostracodarum from Navicula to Diploneis. In Pantocsek's (1892) original description only single measurements of D. ostracodarum were provided (length: 33.5 µm; breadth: 22 µm; striae density: 8 – 9 in 10 µm). However, Jurilj (1954) in his emended diagnosis gave a broader range of dimensions for D. ostracodarum from Lake Ohrid (length: 30 – 55 µm; breadth: 20 – 40 µm; striae density: 6 – 8 in 10 µm). Such wider ranges have also been documented by Jovanovska et al. (2013) in both surface and core samples from Lake Ohrid (length: 28 – 66 µm in surface samples and 27 – 73 µm in core samples; breadth: 17 – 43 µm in surface samples and 14 – 45 µm in core samples; striae density: 7 – 8 in 10 µm in surface samples and 6 – 8 in 10 µm core samples). In Pantocsek's original drawing (1892: pl. 9, fig. 145) the longitudinal canal is composed of one row of areolae throughout the whole length. While the longitudinal canal of the lectotype (Fig. 14) designated here and the Lake Ohrid surface and core populations, is composed of two rows of areolae in the middle of the canal, merging into one at the valve apices (Levkov et al. 2007, Jovanovska et al. 2013). Specimens of D. ostracodarum with one row of areolae throughout the longitudinal canal were not observed in the type material. Stratigraphic remarks: — Neogene (late Middle Miocene - early Late Miocene) to present.	en	Jovanovska, Elena, Buczkó, Krisztina, Ognjanova-Rumenova, Nadja G., Nakov, Teofil, Levkov, Zlatko (2013): Identity and typification of Diploneis ostracodarum, Diploneis budayana and Diploneis praeclara (Bacillariophyta).

03E09278FFDEFFE0FF0CF94AA497185F.taxon	materials_examined	Type: — Căpeni (Köpecz), Neogene fossil deposits in Romania (accession no. BP 88, leg. J. Pantocsek, slide BP 2242, Pantocsek Collection, BP, Lectotype (designated here) = Fig. 30; Slide MKNDC 006290 / C, isolectoype). Observations: — Cleve - Euler (1934) observed fossil specimens of D. praeclara from Scandinavia, and transferred this species into the genus Diploneis (1934: pl. 5, fig. 151). Later, Jurilj (1954) documented an extant population of D. praeclara in Lake Ohrid. With the recent examinations of D. praeclara from Lake Ohrid (Jovanovska et al. 2013), several morphological differences have been documented between Lake Ohrid and Köpecz populations. The major difference between these two populations is the valve outline. Valves from Lake Ohrid surface and core samples have elliptical to linear - elliptic outline with more or less acute apices compared to Köpecz specimens that generally have bluntly rounded apices. The valve size also separates these two populations: length: 31 – 39.7 µm vs. 40 – 74.4 µm; breadth: 16.3 – 18.3 µm vs. 18 – 27.1 µm. Both populations fit Jurilj (1954) observations of D. praeclara (length: 35 – 55 µm and breadth: 15 – 25 µm). However, Pantocsek (1982) did not specify a size range when describing N. praeclara (only a single measurement is given: length 53 µm, breadth 21 µm), and therefore it is difficult to separate these two populations into separate entities. The distinguishing feature of D. praeclara is the distinctly biseriate pattern of areolae of the canal in the middle of the valve. This pattern has been noticed in both populations and therefore they are treated as conspecific. Stratigraphic remarks: — Neogene (late Middle Miocene - early Late Miocene) to present.	en	Jovanovska, Elena, Buczkó, Krisztina, Ognjanova-Rumenova, Nadja G., Nakov, Teofil, Levkov, Zlatko (2013): Identity and typification of Diploneis ostracodarum, Diploneis budayana and Diploneis praeclara (Bacillariophyta).
