A588B0D19EEF5FC2A22F85751A5FCA3B.taxon	etymology	Etymology. The species designation is derived from the term “ Boulouparis ”, which is the one of the main cities on the west coast of New Caledonia. The name “ Berepwari ” is the translation of Boulouparis in xârâcùù, one of the main Melanesian languages spoken in New Caledonia.	en	Prasetiya, Fiddy Semba, Jauffrais, Thierry, Mohamed-Benkada, Mustapha, Callac, Nolwenn, Ansquer, Dominique, Yılmaz, Elif, Lemieux, Claude, Turmel, Monique, Mouget, Jean-Luc, Prabowo, Danang Ambar, Purbani, Debora Christin, Noerdjito, Diah Radini, Fahmi, Varian, Arsad, Sulastri, Gastineau, Romain (2025): Diving into Diversity: Haslea berepwari (Bacillariophyceae, Naviculaceae), a new species of marine diatom from New Caledonia.

A588B0D19EEF5FC2A22F85751A5FCA3B.taxon	description	Description. LM Living cells solitary, motile and lanceolate, equipped with two parietal, narrow band-like chloroplasts appressed to the girdle of the cell (Fig. 2). Valves narrow and lanceolate with acute apices. The maximum and minimum length of the monoclonal culture of H. berepwari was 101.0 μm and 95.4 μm, respectively (average 98.0 ± 1.5 μm, n = 30), while the maximum and minimum width was 15.0 μm and 9.7 μm (average 12.2 ± 1.1 μm, n = 30). On clean frustules, raphe straight with non-distinct central endings. Cell wall exceedingly delicate, with longitudinal and transapical striations not discernible under LM. In general, LM provides minimal visibility into the specifics of the valve characteristics and is not sufficient to distinguish between this species and H. pseudostrearia. SEM In external valve view, the exterior is covered with long, continuous, and apical-oriented siliceous stripes (top layer), proximal raphe endings straight and slightly widened, slightly deflected dorsally, apical raphe endings ventrally hook shaped (Fig. 3 A, D). The interior is composed of a grate-like layer of small areolae, separated by short bars arranged crosswise. Transverse bars of this layer are almost equal in the transapical and longitudinal bars. The areolae are occluded externally by hymens and remnants of this membrane are visible in Fig. 3 D. The central area lacks a lateral extension (Fig. 3 A, D). Internally, the raphe is slightly elevated and straight, with well-developed helictoglossae at the poles (Fig. 3 E). Internal openings of the raphe fissures directed towards one side of the raphe sternum, except at the center and near the tips. Thin bar near the central ending of the raphe on one side of the valve only (Fig. 3 C). A supplementary ridge runs alongside the raphe sternum across most of the valve. Internally, square-shaped areolae organized in orderly rows (Fig. 3 B, C, E). Externally, the valve seems covered with longitudinal bands, separated by slits running parallel to the raphe and converging into a single peripheral slit near the tips (Fig. 3 A, F). The striation displays a transapical pattern of 37 – 38 striae per 10 µm intersected by a longitudinal pattern of 36 striae per 10 µm.	en	Prasetiya, Fiddy Semba, Jauffrais, Thierry, Mohamed-Benkada, Mustapha, Callac, Nolwenn, Ansquer, Dominique, Yılmaz, Elif, Lemieux, Claude, Turmel, Monique, Mouget, Jean-Luc, Prabowo, Danang Ambar, Purbani, Debora Christin, Noerdjito, Diah Radini, Fahmi, Varian, Arsad, Sulastri, Gastineau, Romain (2025): Diving into Diversity: Haslea berepwari (Bacillariophyceae, Naviculaceae), a new species of marine diatom from New Caledonia.
