“…To date, three complexes have been characterized in the Achnanthidium genus: (1) members of the A. minutissimum (Czarnecki 1994: 157) complex, have straight external distal raphe ends, and striae density that increase towards the apex; (2) members of the A. pyrenaicum (Kobayashi 1997: 148) complex, have external distal raphe ends that deflect or hook to one side of the valve; and (3) members of the A. exiguum (Czarnecki 1994: 157) complex, have external distal raphe ends curved in opposite directions (Round & Bukhtiyarova 1996, Krahn et al 2018, Pinseel et al 2015, Compère & Van de Vijver 2011, Jüttner et al 2011, Yu et al 2018, 2019.

Five new species are described in this study: Achnanthidium jiuzhaienis sp. nov., Achnanthidium epilithica sp. nov., Achnanthidium limosua sp. nov., Achnanthidium subtilissimum sp. nov., and Kolbesia sichuanenis sp. nov. Classification was based on light microscopy (LM) and scanning electron microscopy (SEM). A. jiuzhaienis sp. nov. belongs to the “A. pyrenaicum complex” of the genus Achnanthidium, this classification was based on certain characteristics, such as the possession of transpically-elongated areolae and deflected external distal raphe fissures. A. epilithica sp. nov., A. limosua sp. nov., and A. subtilissimum sp. nov. belong to the “A. minutissimum complex” of the genus Achnanthidium, this classification was based on certain characteristics, such as the possession of straight external distal raphe fissures and round or elliptical areolae. Kolbesia sichuanenis sp. nov. was found to belongs to the Kolbesia genus, based on its elongated areolae and striae comprised of one macroareola. All five species were sufficiently different from other similar species to be considered unique separate species based on their valve outline, shape of the axial and center areas, and density of striae of each taxon. These new species derived from the epilithic and epiphytic collections of four alkaline lakes in Jiuzhai Valley, Sichuan Province, Southwest China.

“…Thomas et al 2016;Kulikovskiy et al 2016), and that five or more lineages independently secondarily lost the raphe system on one valve (Kociolek et al, accepted). Within Achnanthidium, however, three morphological groups have been identified, recognized by their distinctive features of flexure of the external distal raphe ends and areolar structure (Karthick et al 2017;Yu et al 2018;Yu et al 2019). Lange-Bertalot (in Krammer & Lange-Bertalot 2004) established the genus Platessa for species not easily assigned to Psammothidium or Achnanthidium.…”

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.

Highlights of new, interesting, and emerging research findings on substratum-associated microbiota covered from a survey of 2019 literature from primarily freshwaters provide insight into research trends of interest to the Water Environment Federation and others interested in benthic, aquatic environments. Coverage of topics on bottom-associated or attached algae and cyanobacteria, though not comprehensive, includes new methods, taxa new-to-science, nutrient dynamics, auto-and heterotrophic interactions, grazers, bioassessment, herbicides and other pollutants, metal contaminants, and nuisance, and bloom-forming and harmful algae. Coverage of bacteria, also not comprehensive, focuses on the ecology of benthic biofilms and microbial communities, along with the ecology of microbes like Caulobacter crescentus, Rhodobacter, and other freshwater microbial species. Bacterial topics covered also include metagenomics and metatranscriptomics, toxins and pollutants, bacterial pathogens and bacteriophages, and bacterial physiology. Readers may use this literature review to learn about or renew their interest in the recent advances and discoveries regarding substratum-associated microbiota. © 2020 Water Environment Federation • Practitioner points • This review of literature from 2019 on substratum-associated microbiota presents highlights of findings on algae, cyanobacteria, and bacteria from primarily freshwaters. • Coverage of algae and cyanobacteria includes findings on new methods, taxa new to science, nutrient dynamics, auto-and heterotrophic interactions, grazers, bioassessment, herbicides and other pollutants, metal contaminants, and nuisance, bloomforming and harmful algae. • Coverage of bacteria includes findings on ecology of benthic biofilms and microbial communities, the ecology of microbes, metagenomics and metatranscriptomics, toxins and pollutants, bacterial pathogens and bacteriophages, and bacterial physiology. • Highlights of new, noteworthy and emerging topics build on those from 2018 and will be of relevance to the Water Environment Federation and others interested in benthic, aquatic environments
