Envekadea metzeltinii sp. nov. is described from periphyton assemblages in the subtropical karstic wetlands of the Florida Everglades, U.S.A. The morphology of the new diatom species is documented by light and scanning electron micrographs and discussed in detail, including comparisons with related species in the genera Envekadea, Caloneis, andNavicula. The new species is characterized by a linear valve outline, a sigmoid raphe course, broad variability in areola shapes and sizes, and two clearly raised axial costae. Apart from the type locality in Florida, the species was observed from similar wetlands in the Yucatan, Mexico. Notes on its ecology and distribution are added.Based on the morphology of the most similar species, Navicula palestinae, the latter is transferred to the genus Envekadea.

In this study, we describe a new freshwater diatom, Navicula daochengensis sp. nov., which was found in a small mountain lake, Lake Congqiancuo, Haizishan Nature Reserve, Daocheng County, Sichuan Province, China. The detailed morphological description of the new species is provided from light and scanning electron micrographs. Navicula daochengensis has a narrowly lanceolate valve outline with broadly-rounded ends. The striate are radiate and convergent to the apices. This new species is compared with similar species, such as Navicula elongata, N. venerablis, N. moralesii and N. radiosa, which differ in size, valve shape, striae density and ultrastructure.

A new monoraphid diatom species Achnanthidium gladiussp. nov. is described from Indonesia. The description is based on molecular data (18SV4), morphological analysis and comparison with similar species. According to molecular data, Achnanthidium gladius sp. nov. is closely related to Achnanthidium minutissimum. Morphologically, the new species differs from similar species by the absence of a fascia on raphe valve, cell size, and striae density and pattern. The new species is only known from the type locality in Indonesia. Comparison with close related species is given.

Cyclotella iranica sp. nov. is described from the Karaj River, Iran. The morphology of Cyclotella iranica is documented with light and scanning electron micrographs and discussed in comparison with several related species: Cyclotella fottii, C. delicatula, C. andancensis var. adnanensis, C. andancensis var. bauzilensis and C. andancensis var. bipolaira. Cyclotella iranica shares with these related Cyclotella species the following features: unequal stria pattern, one sessile rimoportula and several marginal fultoportulae. It is distinguished from them by the position of central fultoportula(e), which is (are) situated at the central end of the striae. It is known only from the type locality; the autecology of Cyclotella iranica shows that it is tolerant of nutrient and organic enrichment.

Bromodesmus catrionae n. gen., n. sp. (type species), B. militaris n. sp., B. riparius n. sp. and B. rufus n. sp. are described. The new genus is characterized by greatly reduced paranota and a gonopod telopodite expanded at the distal end into a posteriorly concave hood fringed with teeth; the hood partly protects a long, curved, acutely pointed solenomerite. Male leg setation in the type species of six Tasmanian dalodesmid genera is briefly discussed and illustrated with scanning electron micrographs. The sphaerotrichome shaft is sharply pointed in Atrophotergum; gently tapered in Dasystigma, Lissodesmus and Tasmanodesmus; expanded at the tip in Bromodesmus; and entirely absent in Gasterogramma. Tips of the setae forming the dense ventral brush on male podomeres are gently tapered in Dasystigma and Lissodesmus, truncated in Gasterogramma, expanded in Bromodesmus and forked in Tasmanodesmus.

The genus Guilielmia Weise from the high mountains of Central Africa, known on a female specimen only, is redescribed based on new specimens of the type species, and the new species Guilielmia leleupi sp. nov. described here. Habitus photos, and microscope and scanning electron micrographs of diagnostic characters, including the aedeagus, are provided for both the species. Some considerations about taxonomic affinities and morphological adaptations to high altitudes are suggested.
