“…While working on the diatom biodiversity of a karst landform in Guizhou, we observed many interesting diatom species, resulting in the description of one new genus and eleven new taxa (Kociolek et al 2016a(Kociolek et al , b, 2019Lowe et al 2017;You et al 2016You et al , 2017You et al , 2019Yu et al 2017b). The aim of this article is to describe three new Achnanthidium species, based on light microscopy (LM) and scanning electron microscopy (SEM) of cleaned materials from this same karst landform.…”

Three new subaerial species of Achnanthidium are examined and described from a karst landform of central-south China based on light and scanning electron microscopy observations, and are compared with similar taxa worldwide. A. mediolanceolatum sp. nov. is elliptical-lanceolate, not linear-lanceolate as is more typical in this genus, as well as having a bow-tie shaped central area on the raphe valve and a large lanceolate axial area on the rapheless valve, features which together make it easy to distinguish this species from others. A. parvulum sp. nov. and A. guizhouensis sp. nov. are linear-elliptical in shape, which is more common for Achnanthidium and they differ from other species mainly in size, raphe, density of striae and shape of the central area. We compared these three new species with morphologically-similar taxa, and present their ecological settings and distributions as well. The relationship between Achnanthidium and Psammothidium is discussed, and the data from these new species from Guizhou presented herein suggest the two genera are difficult to separate.

This survey of literature on substratumassociated microbiota from 2016 includes highlights of research findings associated with algae, cyanobacteria, and bacteria from a variety of aquatic environments, but primarily freshwaters. It covers topics of relevance to the Water Environment Federation along with those of emerging or recent interest such as nuisance, bloom forming and harmful algae, fossil fuel related contamination, and other environmental pollutants like nanoparticles. Additional interesting findings reported on include general ecology, method development, multistressor interactions, nutrient cycling, taxonomy and systematics, trophic interactions, and biomonitoring, bioassessment, and bioremediation.

“…As a part of our continuing study of the freshwater diatoms of Guizhou Province, China (Kociolek et al 2016a(Kociolek et al , 2016bYou et al 2016You et al , 2017Lowe et al 2017;Yu et al 2017), we encountered a species of Achnanthes for which we can find no previous description. The purpose of the present report is to present light and scanning electron microscope observations of this Achnanthes species from Guizhou, and to offer a formal description of it as a species new to science.…”

SUMMARY Achnanthes maolanensis nov. sp. is a large diatom collected from subaerial, freshwater habitats in karst landforms in central‐south China. Living cells have two chloroplasts. Valves of this new species are panduriform in outline, slightly constricted in the middle part of the margins, with uniseriate areolae; the raphe is filiform, and there is a linear, thickened stauros in the central area of the RV. On the ARV, there is no central area, and as well there are no terminal orbiculi, marginal ridge, or terminal spine externally. The axial area (rapheless sternum) is located down the center, not offset from the center as in many other species of the genus and is narrow and almost straight. This suite of characters makes the new species easy to distinguish from other species in the genus. Its presence adds further documentation of the unique and diverse freshwater diatom flora from karst habitats in this region of China.
