Revision of the macropterous subgenus from east China, with the description of a new species (Carabidae, Zabrini, Amara).

Species from east China belonging to the subgenus Curtonotus were studied, resulting in the description of a new species, Amara (Curtonotus) beijingensis The type locality is Xiaolongmen Forest Park in Beijing. All the known macropterous species from eastern China are reviewed and for each species taxonomical notes, illustrations, and new provincial records are noted. An improved key for their identification is provided as well.

Taxonomic revision of the genus Fairmaire (Tenebrionidae, Eurynotina): shortfalls of anatomical nomenclature with notes on aedeagal homology.

The genus Fairmaire (Tenebrionidae, Blaptinae, Platynotini, Eurynotina) is revised. Two new species and one new synonymy are presented along with new diagnoses, descriptions, a distribution map, and key to species. The resulting species of are: , Koch (= Koch ), , Koch, and Fairmaire.

The Acidocerinae (Coleoptera, Hydrophilidae): taxonomy, classification, and catalog of species.

The cosmopolitan subfamily Acidocerinae (Coleoptera: Hydrophilidae) is one of the largest and most taxonomically challenging lineages of water scavenger beetles. Recent phylogenetic studies have substantially advanced our understanding of acidocerine relationships but also illuminated the twin challenges of poorly delineated generic concepts and a classification broadly incompatible with the phylogeny. Here, these two challenges are addressed by providing a comprehensive synthesis and taxonomic tools for the Acidocerinae, including (1) a brief history and the current state of acidocerine classification, (2) a review of acidocerine ecology and collection methods, (3) the current knowledge of larval and fossil acidocerines, (4) a morphological primer on characters of taxonomic and systematic importance within the lineage, (5) a key to the world genera of Acidocerinae, (6) diagnoses, habitus, and aedeagal images, distribution maps, and summary of knowledge for each of the 23 extant genera in the subfamily, and (7) a complete annotated taxonomic catalog including the published distributions, synonyms, and references for all described 541 acidocerine species recognized as of 1 April 2021.

Review of the Neotropical water scavenger beetle genus Short & García, 2007 (Coleoptera, Hydrophilidae, Acidocerinae): new lineages, new species, and new records.

The water scavenger beetle genus Short & García, 2007 currently contains ten species, including one known but formally undescribed taxon. Although was revised in 2017, ongoing fieldwork as well as an expanded concept of the genus has led to the recognition of numerous additional species. Here a combination of morphological and molecular data is presented to review this newly found diversity.

Notes on (Ascomycota, Leotiomycetes), with new species and combinations.

Studies of (Leotiomycetes, Helotiales, Cenangiaceae) are scarce. Here, we describe two new species based on molecular phylogenetic data and morphology. was collected at the Boston Harbor Islands National Recreation Area, Massachusetts.

New species of (Agaricales, Inocybaceae) from Pakistan revealed by morphology and multi-locus phylogenetic reconstruction.

During fungal surveys between 2012 and 2014 in pine-dominated forests of the western Himalayas in Pakistan, several collections of (Agaricales, Inocybaceae) were made. These were documented, based on morphological and molecular data. During this work, three new species came to light, which are here formally described as , and .

Studies of Neotropical tree pathogens in : a new species, , and new combinations for and .

The crinipelloid genera and (Agaricales, Marasmiaceae) are characterized by basidiomes that produce long, dextrinoid, hair-like elements on the pileus surface. Historically, most species are believed to be saprotrophic or, rarely, parasitic on plant hosts. The primary morphological diagnostic characters that separate and are pliant vs.

Taxonomic revision of the genus Fåhraeus, 1870 (Tenebrionidae, Pimeliinae, Asidini).

The taxonomic concept of the genus Fåhraeus, 1870 is tested and revised based on newly identified material. The following new species are described: , , , and Kamiński. Wilke, 1925 is considered as a junior subjective synonym of Péringuey, 1899.

A new species of (Ustilaginales) from the volcanic island of Kosrae, Caroline Islands, Micronesia.

is an unusual genus of smut fungi containing two described species that produce sori as adventitious gall-like spikelets on members of tribe (subfam. Mapanioideae, Cyperaceae). In September 200, during a botanical expedition on the volcanic island of Kosrae located in the eastern Caroline Islands and within the Federated States of Micronesia, a specimen of was collected displaying -like sori in adventitious spikelets on the host leaves.

A new species of frog-biting midge from Papua New Guinea with a key to the described Corethrellidae of the Australopapuan region (Diptera, Corethrellidae, ).

Kvifte & Bernal, is described based on one male and six female specimens collected at 2200 m a.s.l.

in North America: distribution and natural host range.

, a rust fungus pathogen of Carolina bristlemallow, (Malvaceae), is newly reported from North America, appears to be well established along the Gulf coast and is likely to have been introduced from South America. Its taxonomy, distribution and natural host range are discussed and a lectotype designated for this species. and are reported as new hosts for the rust.
