Reichardt 2015	<div><p>Gomphonema guayabense E.Reichardt, sp. nov. (Figs. 1–14)</p> <p>Cells nearly rectangular in girdle view, mantles without additional structures except for the endings of the transapical striae. Valves rhombic-lanceolate, only slightly gomphonemoid-cuneate with obtusely rounded headpole and broadly rounded or subcapitate rounded foot pole. Length 55–95 μm, width 10–15 μm. Raphe lateral, external fissures nearly straight, internal fissures weakly arched. External and internal central raphe endings conspicuously different, the latter about four times wider apart and abruptly deflected to the same side. Axial and central area combined to form a broad rhombic-lanceolate hyaline field. No isolated pore (stigmoid) present in central area. Striae short, slightly radiate, 8–10 in 10 μm, more densely spaced near the ends and clearly elongated near the foot pole. Areolae in striae 24–28, mainly circa 28 in 10 μm.</p> <p>In SEM external views show irregularly C- to 3-shaped areolar foramina situated in depressions clearly visible in oblique view (Figs. 9, 12). On the mantle the foramina are less arched and more broadly slit-like (Fig. 10), near the footpole the last 2–3 striae consist of small round foramina only (Fig. 13). At the edge of the valve face/mantle junction the interstriae are studded with small granula (Figs. 9–10, 12). Central raphe fissures approximate, straight and slightly expanded to form elongate, slightly drop-shaped central raphe endings (Fig. 9). At the foot pole a large nearly round pore field is present, bisected by the terminal raphe fissure on the valve face, but with poroids running continuously around the lower part of the polar mantle as the raphe fissure terminates within the pore field (Fig. 13). Internally the central raphe fissures are situated in an apically elongated central nodule, deflected to the same side and recurved at their ends (Fig. 14). Helictoglossa at the distal raphe endings shifted to the secondary side especially at the foot pole (Fig. 11). Alveoli with straight margins, stubs or struts are lacking (Fig. 14). Well-developed pseudosepta are present at both poles (Fig. 11).</p> <p>Type:— CUBA. Salto del Guayabo. From mosses, Andreas Müller, 6 September 2003. Coll. Reichardt sample S2450 (holotype slide S2450- T01 Coll. Reichardt, Botanical Museum Berlin (B) holotype represented by Fig. 1; isotype slide Zu 9/99, Hustedt Collection, Bremerhaven (BRM)).</p> <p>Etymology:— This taxon is named after the type locality Salto del Guayabo.</p></div> 	https://treatment.plazi.org/id/03DB226AFFEDFF86FF18FE0E0366FCEE	Public Domain	No known copyright restrictions apply.

Reichardt 2015	<div><p>Gomphonema curatorum E.Reichardt, sp. nov. (Figs. 15–34)</p> <p>Cells in girdle view barely clavate, nearly rectangular, mantles without additional structures except for the endings of the transapical striae. Valves only slightly gomphonemoid-cuneate, lanceolate with obtusely rounded ends. Larger valves somewhat inflated at mid-valve. Length 31–72 μm, width 6–9 μm (initial valves up to 13 μm). Raphe lateral, external fissures weakly arched to nearly straight, internal fissures slightly more arched. External and internal central raphe endings clearly distinguishable, the latter wider apart and deflected to the same side. Axial and central area combined to form a broad lanceolate hyaline field. No stigmoid present in central area. Striae slightly radiate to nearly parallel, 9–12 (mostly 10–12) in 10 μm, more densely spaced near the foot pole. Areolae in striae difficult to distinguish.</p> <p>In SEM most ultrastructural details correspond to G. guayabense (Figs. 28–34) but G. curatorum lacks the granula present at the edge of the valve face/mantle junction in G. guayabense (Figs. 29–30, 32–34) and the pore field at the foot pole is clearly smaller (Fig. 30). The foramina in the axial area are often more clearly C-shaped (Figs. 32, 34) and roundish to kidney-shaped depressions can be present around the external central raphe endings (Fig. 32). Helictoglossa at the internal distal raphe endings only slightly or inconspicuously shifted to the secondary side (Fig. 28).</p> <p>Type:— CUBA. Salto del Guayabo. From mosses, Andreas Müller, 6 September 2003. Coll. Reichardt sample S2450 (holotype slide S2450- T02 Coll. Reichardt, Botanical Museum Berlin (B), holotype represented by Fig. 18; isotype slide Zu 9/99, Hustedt Collection, Bremerhaven (BRM)).</p> <p>Etymology:— This taxon is dedicated to all curators of diatom collections, especially to Friedel Hinz, curator of the Friedrich Hustedt-collection at Bremerhaven (BRM) for many years.</p> <p>Distribution and Ecology:— Gomphonema guayabense and G. curatorum are only known from the type locality so far. The diatom flora of the type material is dominated by species of the genera Achnanthidium, Encyonema and Encyonopsis which often occur with strong appearance in semi aquatic habitats like trickled mosses (Reichardt 2011). However, there is a remarkable occurrence of Brachysira australofollis Lange-Bertalot &amp; Moser (1994: 17) in this sample, constituting about 6% of the diatom population. Brachysira australofollis is only known from New Caledonia and was found there associated with diatoms like e.g. Brachysira spp. and Frustulia spp. indicating acidic water. Diatoms of these genera are also present in the sample from Salto del Guayabo, Cuba. Therefore similar ecological conditions can be postulated.</p> </div>	https://treatment.plazi.org/id/03DB226AFFE8FF80FF18FF4706B2FB5B	Public Domain	No known copyright restrictions apply.
