The two names Urginea amboensis Baker and Albuca reflexa K.Krause & Dinter are formally placed in synonymy under Drimia zambesiaca (Baker) J.C.Manning & Goldblatt to accord with the current taxonomy. The recently described monotypic genus Triandra Mart.-Azorín et al. is also included in Drimia and the necessary transfer of T. pellabergensis Mart.-Azorín et al. to Drimia is effected, along with the second known locality for the species, representing a significant range extension. A total of 80 species of Drimia are now recognised in southern Africa. Updated identification keys to the species in sections Capitatae, Ledebouriopsis, Macrocentrae, Physodia and Thuranthos are provided. ","PeriodicalId":55336,"journal":{"name":"Bothalia","volume":"585 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77014661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Pseudoplectania africana (Sarcosomataceae, Pezizales), a new species from South Africa","authors":"Z. Sochorová, M. Carbone, M. Sedlářová, A. Polhorský, M. Sochor","doi":"10.38201/btha.abc.v52.i1.1","DOIUrl":"https://doi.org/10.38201/btha.abc.v52.i1.1","url":null,"abstract":"Background: An undescribed species of Pseudoplectania was found during an excursion in Mpumalanga.Objectives: To describe Pseudoplectania africana M.Carbone & Sochorová as a new species and to evaluate presence of crystals as a diagnostic character in Pseudoplectania.Methods: The description was based on standard macro- and microscopical methods. Presence of crystals was tested for in UV light. Phylogeny was inferred using sequencing of the LSU and ITS loci.Results: Pseudoplectania africana is characterised by shortly stipitate to sessile apothecia up to 18 mm broad, richly developed basal tomentum, ascospores with an eccentrically positioned, relatively small sheath, straight, sometimes bifurcate paraphyses, wavy to coiled external hairs and presence of large yellow crystals mainly in the hymenium and ectal excipulum. It was found on a decaying coniferous trunk. The species forms a distinct lineage in the clade with P. tasmanica and P. ericae. All of these three species exhibited presence of the large yellow crystals (sulphur yellow in UV light). No or only small hyaline crystals (whole mount blue in UV light) were found in P. nigrella, P. lignicola, P. episphagnum and P. melaena.Conclusion: The new species represents the first report of Pseudoplectania in South Africa and probably also in the whole of continental Africa. Crystals in hymenium and excipulum appear to be an important trait in Pseudoplectania taxonomy.","PeriodicalId":55336,"journal":{"name":"Bothalia","volume":"184 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85452559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three distinct scarabaeine dung beetle assemblages defined from ordination were largely centred on the three habitat types. Out of a total of 61 species, greater numbers were associated with grassland (38) than sand (17) and dune forest (6) although abundance was greater in both dune forest and grassland than in sand forest. Biogeographical classification indicated that >40% of the species are endemic to the east coast of southern Africa with the remainder centred in adjacent savanna. Endemic east coast species were well represented in both forest (15) and grassland (11). Savanna species were better represented in grassland (27) than forest (8). Proportions of grassland species and their abundance declined across increasing patch sizes of sand forest becoming lowest in dune forest.Conclusions: Conservation of endemic, east coast dung beetle species requires the preservation of both natural grassland and sizeable patches of forest in an undisturbed habitat mosaic. As the east coastal system is relatively small in extent with the MCE widely transformed in South Africa, the MSR is an important contributor to regional conservation of endemic species.","PeriodicalId":55336,"journal":{"name":"Bothalia","volume":"62 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88861649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
