title: Hidden treasures of herbaria - even small collections contain a wealth of diversity: the powdery mildews of the North Carolina State Larry F. Grand Mycological Herbarium

description: This dataset contains the digitized treatments in Plazi based on the original journal article LaGreca, Scott, Crouch, Uma, Paul, Andrew, Thomas, Jacklyn, Thompson, Jake, Shaw, Christian, Cubeta, Marc A., Braun, Uwe, Bradshaw, Michael (2025): Hidden treasures of herbaria - even small collections contain a wealth of diversity: the powdery mildews of the North Carolina State Larry F. Grand Mycological Herbarium. IMA Fungus 16: e 156231, DOI: 10.3897/imafungus.16.156231AbstractThe occurrence of cryptic species is well documented in fungi but the extent of their diversity is not fully understood. This study assessed the fungal diversity within a part of the Larry F. Grand Mycological Herbarium (NCSLG), a small, well-maintained collection at North Carolina State University, with a focus on the powdery mildew fungi (Erysiphaceae). Erysiphaceae were selected due to their economic impact as plant pathogens and availability of extensive DNA sequence data for multiple barcode loci. Our research objectives included determining the number of phylogenetic species compared with those identified morphologically, and to identify undescribed species. We generated sequence data for 220 of the 299 powdery mildew specimens (73 % success rate) in the herbarium, which represented 60 species in 10 genera, collected from 134 host plant species. Our analyses revealed that ~ 83 % (183 / 220) of the sequenced specimens had identifications that were incorrect and / or outdated based on current genus / species concepts. Additionally, four new species are described: Erysiphe amphicarpaeicola, E. ulmi-alatae, E. quercus-virginianae, and Takamatsuella grandii. A specimen deposited at NCSLG is designated as an epitype for Phyllactinia liriodendri, and a species of Phyllactinia identified on Carpinus caroliniana, as well as multiple species infecting Quercus spp., likely represent additional undescribed species that require more data. This research highlights the critical role of herbarium collections in uncovering fungal biodiversity, and underscores the importance of preserving these valuable resources, particularly with the growing trend to discard herbaria due to financial and space constraints.

A fourth species, Ifrika pauculihirta comb.n., is transferred from Dissomphalus. The males of this genus are easily recognised among the other genera of Pristocerinae by having the following combination of characteristics: the median clypeal lobe indistinct from the lateral ones, the dorsal pronotal area very short, the hypopygium with an inner membrane and a posterior margin deeply excavated, the genitalia with the harpe strongly incurved, almost fully divided, the aedeagus with a basal cover plate, the mediodorsal fold, and the median projection ventrally curved and apodeme dorsally curved. A key to all species and some comments on the Afrotropical Bethylidae fauna are also provided.06 November 2023KEYWORDSChrysidoidea; Central African Republic; Gabon; Kenya; Pristocerinae; Ugandahttp://www.zoobank.org/ urn:lsid:zoobank.org:pub: 76C9CD41- F991-4F4E-9E4C-C16E2F62ECC3

This last new species is dedicated to John Rawlins: Neoboenasa rawlinsi sp. n. and seems to be a scarce endemic of the high altitudes in the Sierra de Neiba. On this occasion the generotype of Boenasa, Boenasa nigrirosea Walker, [1865], is fully redescribed.

By using Bayesian inference (BI) and maximum likelihood (ML) methods, six lignicolous species were identified, including four novel taxa: Plectania damingshanensis sp. nov., Plectania huapingensis sp. nov., Pseudoplectania aureonigrescens sp. nov., and Urnula auricularioides sp. nov.; and two new distribution records: Plectania lutea and Urnula ailaoshanensis. Keys to species of Plectania, Pseudoplectania, and Urnula were provided.

Observations of reproductive strategies for some dendrochirotid holothuroids (Echinodermata: Holothuroidea: Dendrochirotida). Memoirs of Museum Victoria 66: 215–220.Some recently observed dendrochirotid holothuroid reproductive strategies are reported for the first time: fissiparity by Cucuvitrum rowei O’Loughlin and O’Hara; probable intra-coelomic brood fissiparity by Staurothyone inconspicua (Bell); intra-coelomic brood-protection by a species of Parathyonidium Heding; intra-coelomic brood auto-ingestion by Neoamphicyclus materiae O’Loughlin; brood-protection in anterior interradial marsupia by Psolidiella mollis (Ludwig and Heding). Some analysis is reported of marsupial brood-protection by Antarctic dendrochirotid holothuroids: the “ Cucumaria georgiana group”; Echinopsolus acanthocola Gutt; Echinopsolus parvipes Massin; Microchoerus splendidus Gutt; Psolidiella mollis (Ludwig and Heding); Psolus charcoti Vaney. Confusion in the literature about brood-protection by the Subantarctic dendrochirotid Cladodactyla crocea (Lesson) is clarified.

Zootaxa 1892: 35-52, URL: http://hol.osu.edu/reference-full.html?id=22424AbstractThe Afrotropical ponerine ant genus Phrynoponera is revised and a worker-based key to species presented. Five species are recognised of which two (pulchella and transversa) are described as new. Two new junior synonyms of the type-species gabonensis are established (armata, heterodus) and earlier synonymy of some infraspecific taxa is confirmed. The genus is redefined, with diagnoses of all castes and sexes. New and important characters of the genus are discussed.Key words: Phrynoponera, Ponerinae, Ponerini, taxonomy

title: Notes on carabid beetles of the genera Coleolissus and Siopelus (Coleoptera: Carabidae: Harpalini), with description of four new species with unusual aedeagi from India and China

description: This dataset contains the digitized treatments in Plazi based on the original journal article Kataev, Boris M. (2022): Notes on carabid beetles of the genera Coleolissus and Siopelus (Coleoptera: Carabidae: Harpalini), with description of four new species with unusual aedeagi from India and China. Zootaxa 5168 (3): 285-305, DOI: 10.11646/zootaxa.5168.3.2AbstractNew data on the taxonomy, morphology and distribution of several species of the genera Coleolissus Bates, 1892 and Siopelus Murray, 1859 from the southern Palaearctic and Oriental regions are provided, with special attention to the structure of their male genitalia. Coleolissus perlucens (Bates, 1878), originally described as Hypolithus perlucens Bates, 1878, the type species of Coleolissus, and C. iris Andrewes, 1924 are re-described based on the holotypes and the additional material. The following four new species with unusual aedeagi are described: C. kejvali sp. n., C. deformipenis sp. n., and C. monstrosipenis sp. n. from Western India, and Siopelus (Neosiopelus) liangi sp. n. from Yunnan, China. The extremely unusual shape of the aedeagus of C. monstrosipenis sp. n. is discussed. It is supposed that the highly modified apical portion of the aedeagus in this species takes over some of the mechanical functions of the internal sac during mating. The following new synonyms are proposed: Coleolissus iris Andrewes, 1924 = Calathomimus splendens Ito, 1997, syn. n. = Coleolissus turturensis Ito, 2016, syn. n. The following taxa are recorded for the first time: Coleolissus iris from the Indian states of Punjab and Kerala, and the genus Siopelus (subgenus Neosiopelus Basilewsky, 1946) from China.
