Length 27–62 µm, breadth 10–14 µm. Axial area straight, forming an orbicular central area that does not extend to the margin. Raphe lateral, with distinctly dilated external proximal raphe ends. External distal raphe ends extend nearly straight from the valve face to mantle, bisecting the distinct apical pore fields at footpole. Central area with 4–7 isolated stigmoids around the central area. Striae costate, individual areolae not visible with LM. Striae strongly radiate about the center of the valve, becoming parallel at both poles. Striae 13–15 in 10 µm. Prominent septa and pseudosepta at both poles.</p> <p>In the SEM, the interior of G. hastata is dominated by the round central area (Figs 376, 377). The central nodule is raised internally, and the elevated raphe terminates on the central nodule with proximal raphe ends that are recurved in the same direction (Fig. 377). Around the base of the central nodule is located 4 isolated stigmoids. The stigmoids are occluded with siliceous coverings, around the base of each are small pores (Fig. 377). Septa are associated with girdle bands at the poles (Fig. 376). Externally, the central area has the stigmoids that occur in small, round depressions (Fig. 378). Proximal raphe ends are elongated and dilated (Fig. 378). The doubly-punctate striae extend from the mantle to the valve face, terminating next to the axial area with 1 or 2 areolae (Figs. 378). Valvocopula has a single row of pores (Fig. 379).</p> <p>Observations:— The orbicular shape of the central area, not extending to the margin and the costate nature of the striae help to distinguish this species from other, similar species in the genus.</p></div> 	https://treatment.plazi.org/id/242F87F03A59DD0FB6FDFF10F797FC98	Public Domain	No known copyright restrictions apply.

The axial area, interstriae and central area appear to be elevated from the level of the areolae. Striae are composed on 2, sometimes 3 rows of areolae (Figs 369, 371). At the central area the stigmoids are round and appear to occur in slightly sunken depressions (Fig. 370). The poles have the distal raphe ends bent onto the mantle (Figs 369, 371), while at the footpole the apical pore fields appear as compressed striae (Fig. 371). Internally, an overall view shows the presence of septa at both poles (Figs 372, 374). The internally elevated, elliptical central nodule bears the proximal raphe ends (Figs 372, 373, 375). The proximal raphe ends are recurved in the same direction. Around the base of the central nodule there 4 isolated stigmoids (Figs 373, 375).

In every one of the Gomphoneis species we observed in Lake Baikal, features shared include doubly-punctate striae, apical pore fields at the footpole that are undifferentiated, presence of septa and pseudosepta, and a central nodule bearing proximal raphe ends recurved in the same direction.</p> <p>There were several taxa and features that were variable across members of the genus. For example G. lata has robust interstriae and in some specimens or on certain portions of the valve (apices), striae were composed of both 2 and 3 rows of areolae. Gomphoneis lata and G. tumida (see figures 383–387) both exhibited stigmoids with teeth-like projections internally, and that feature is also present in G. marvanii (Reichardt 2009, figure 82).</p> <p>Gomphoneis hastata and its allies, as well as G. eriensioides (figures 398, 401), have external stigma openings that occur in small depressions on the valve face. Internally, the stigmoids are occluded, and there are small openings around the stigma. Also, relative to the stigmoids, G. capitata showed 4 isolated stigmoids externally, but only two stigma openings internally (Figs 392–395). Internal stigma openings are not occluded in G. capitata sp. nov., and this feature is also seen in G. inconspicua sp. nov. (Fig. 409), G. skabitchevskii sp. nov. (Fig. 410) and G. cf. subcapitata (Fig. 406).</p> <p>Position of the apical pore field in most Gomphoneis taxa is both on the valve face and valve mantle. This is known in both major groups within the genus, and across many taxa in the Elegans subgroup (Kociolek &amp; Stoermer 1986, 1988b; Levkov et al. 2007; Tuji 2005; You et al. 2013). There were two taxa in Lake Baikal, however, where the apical pore fields were structured differently. In G.potapovae sp. nov. (Figs 417, 418), and G. strelinkovae sp. nov. (Fig. 412, 413), the apical pore field does not extend onto the valve face, but rather is restricted to the valve mantle; this is also seen in G. sp. cf. reichardtii (Fig. 421).</p> <p>This variation in the valve structure in stigmoid or astigmoid groups of Gomphoneis has not been recognized previously. Further assessment of these features in recently described, or historically known taxa, may help to further resolve evolutionary relationships of the Gomphoneis taxa within and outside of Lake Baikal. Such a detailed understanding of the relationships of these taxa may yield an understanding of the distributions across the lake and the arc eastward from the Balkans to eastern Asia through NW China, Mongolia, Lake Baikal and the Russian Far East to Japan, and westward from North America.</p> </div>	https://treatment.plazi.org/id/242F87F03A4DDD1CB6FDFCCBF7CAF85A	Public Domain	No known copyright restrictions apply.
