The majority of Euglyphida species are characterised by shells with imbricated silica scales. Environmental surveys indicate a large unexplored diversity and recent efforts hinted at a certain diversity of yet undescribed, inconspicuous, scale‐lacking Euglyphida. Here we describe Phaeobola aeris gen. nov., sp. nov. that shows a variety of morphological characters typical for the Euglyphida but lacks silica scales‐instead, this species bears an agglutinated test. Neither its morphology nor phylogenetic placement allows its assignment to any currently described family. We erected the yet monospecific genus Phaeobola gen. nov., which with yet available data remain Euglyphida incertae sedis.

“…On the other hand, their habitats are geographically remote, and no molecular data are available for Page's strain. The extent of cryptic speciation has been getting more and more evident among the naked lobose amoebae recently (Kudryavtsev, Pawlowski, 2015;Tekle, Wood, 2018;Mesentsev, Smirnov, 2019;Kudryavtsev, Volkova, 2020;Lara et al, 2020;Mesentsev et al, 2020). For example, among the small dactylopodid amoebae that belong to the genus Cunea no sound morphological differences were found between three strains showing significant variation in their molecular sequences and ecological preferences (Kudryavtsev, Pawlowski, 2015;Kudryavtsev, Volkova, 2020).…”

“…Although morphologically (almost) indistinguishable these so-called “pseudocryptic” species do differ from each other according their ecological preferences (Singer et al, 2018) and their global distributions (Singer et al, 2019). The combination of barcoding, distributional and ecological evidence indicates that these taxa should be considered as true biological species (Lara et al, 2020). Given the difficulties with identification of some taxa based solely on their morphology, a molecular approach is required for the collection of reliable distributional assessment.…”

Environmental DNA-based diversity studies have increased in popularity with the development of high throughput sequencing technologies. This permits the potential simultaneous retrieval of vast amounts of molecular data from many different organisms and species, thus contributing to a wide range of biological disciplines. Environmental DNA protocols designed for protists often focused on the highly conserved small subunit of the ribosome gene, that does not permit species-level assignments. On the other hand, eDNA protocols aiming at species-level assignments allow a fine level ecological resolution and reproducible results. These protocols are currently applied to organisms living in marine and shallow lotic freshwater ecosystems, often in a bioindication purpose. Therefore, in this study, we present a species-level eDNA protocol, designed to explore diversity of Arcellinida (Amoebozoa: Tubulinea) testate amoebae taxa, that is based on mitochondrial cytochrome oxidase subunit I (COI). These organisms are widespread in lentic water bodies and soil ecosystems. We applied this protocol to 42 samples from peatlands, estuaries and soil environments, recovering all the infraorders in Glutinoconcha (with COI data), except for Hyalospheniformes. Our results revealed an unsuspected diversity in morphologically homogeneous groups such as Cylindrothecina, Excentrostoma or Sphaerothecina. With this protocol we expect to revolutionize the design of modern distributional Arcellinida surveys. Our approach involve a rapid and cost effective analysis of testate amoeba diversity living in contrasted ecosystems. Therefore, Arcellinida clade have the potential to be established as a model group for an array of theoretical and applied studies.
