   "abstract": "Navicula gibbula\u00a0Cleve and its allies have a number of morphological characters which are visible under the light microscope and distinguish them from taxa included in\u00a0Navicula\u00a0Bory sensu stricto. These include proximal raphe ends which are sharply and unilaterally hooked and often extend beyond the central area, as well as two apparently thickened longitudinal ribs which extend the length of the valve on either side of the raphe. With the use of the SEM additional well-defined characters of the\u00a0N. gibbula\u00a0complex become apparent. Distal raphe ends are bifurcate and the valve face and mantle possess bipartite walls similar to those in\u00a0Neidium\u00a0Pfitzer. Furthermore, the apparently thickened longitudinal ribs are actually hollow canals, a feature reminiscent of the longitudinal canals of\u00a0Diploneis\u00a0Ehrenberg. Characters of the group are particularly well-defined and distinct from those of other genera, justifying separation from\u00a0Navicula. Based on the valve morphology of\u00a0N. gibbula\u00a0and all other members of the section\u00a0Naviculae fistulatae\u00a0McCall, we separate these taxa from\u00a0Navicula\u00a0and resurrect the genus\u00a0Muelleria\u00a0Frenguelli to include them.",
