Kondratyuk, S. Y., Karnefelt, I., Thell, A., Elix, J. A., Kim, J. A., Kondratiuk, A. S. & Hur, J.-S. 2015. Ovealmbornia reginae (Teloschistaceae, Ascomycetes), a new xanthorioid lichen from South Africa. — Herzogia 28: 465–472. A new species, Ovealmbornia reginae from South Africa, is described, illustrated and compared with related species. A combined phylogenetic data set based on ITS and 28S nrLSU and 12S mtSSU sequences of the genera in the Dufourea clade is provided, (i. e. the genera Dufourea, Jackelixia, Langeottia, Ovealmbornia and Xanthokarrooa). Corrections of GenBank data for the genus Ovealmbornia and a key to the species of the genera Ovealmbornia and Xanthokarrooa are provided.

New genus Upretia S. Y. Kondr., A. Thell and J. S. Hur is characterized by partly pruinose, lobate to subsquamulose, olivaceous grey to brown thallus, small ascospores and narrowly bacilliform conidia. It belongs to the subfamily Caloplacoideae of the Teloschistaceae and includes the ‘Caloplaca’ amarkantakana clade. The new genus is closely related to Ioplaca Poelt according to phylogeny analysis based on ITS1/ITS2 nrDNA, 28S nrLSU and 12S mtSSU sequences. The new combination Upretia amarkantakana is proposed Caloplaca amarkantakana Y. Joshi and Upreti.
