Phylogenetic analysis was performed via Bayesian inference and maximum likelihood methods complemented with Genealogical Concordance Phylogenetic Species Recognition (GCPSR) using the PHI test. The results indicated that the specimen in study belongs to the genus <em>Jaltomata sp</em>. <em>nov</em>. supported by PHI test (φ=1.0) showing no evidence of recombination. Characteristics of corolla, pedicel and calyx, stigma, anthers, fruit, and seeds, differentiated this species. Based on the results, the name <em>Jaltomata tlaxcala</em> is proposed for this new species.</span></span></span></p>2024-03-18T00:00:00+13:00Copyright (c) 2024 Phytotaxahttps://phytotaxa.mapress.com/pt/article/view/phytotaxa.641.2.2<strong><em>Lutophila gen. nov.</em>, a new diatom genus from the hottest place on Earth, Lut Desert, Iran</strong>2023-12-01T03:53:29+13:00SOMAYYEH KHEIRIsomayyeh.kh@gmail.comMARK B.

It was recorded in vegetation survey of Elephantine Island in Aswan Governorate in 2020, then it was recorded in Dakhla Oasis in the Western Desert in 2023. The species identity was confirmed by a comparative macromorphological study between the collected specimens and herbarium specimens from other countries, and live specimens cultivated in Antoniades Botanic Garden in Alexandria. The occurrence of this species in the natural habitats of Egypt represents an important disjunction of the biogeographic relevance and raises concerns. The species may cause negative impacts to native species, outcompeting species of the same functional group, or can increase fire hazards in the invaded areas. Taking into consideration that the species has already been naturalized in some countries, its further expansion in Egypt is a possibility. It is of great concern to monitor and control the spread of the species in Egypt and possibly promote an early eradication. Notes on the habitat in which the species has been recorded and its invasive status in Egypt and surrounding nations are discussed.</span></span></span></p>2024-03-18T00:00:00+13:00Copyright (c) 2024 Phytotaxahttps://phytotaxa.mapress.com/pt/article/view/phytotaxa.641.2.4<strong><em>Pseudoconiocessia xishuangbannaensis </em>gen. et <em>sp. nov.</em> in Coniocessiaceae, Xylariales from <em>Coffea liberica</em> in China</strong>2023-12-04T04:30:53+13:00LI LU6371105004@lamduan.mfu.ac.thSAMANTHA C.

Maximum likelihood and Bayesian analyses of combined ITS, LSU, and <em>RPB</em>2 genes showed that the two isolated fungal strains belonged to a distinct species in Coniocessiaceae and were well separated from closely related genera with 73% ML and 0.92 PP statistical support. Morphologically, this distinct species can be differentiated from other genera in Coniocessiaceae by aseptate hamathecium, 4–8-spored asci with a flat apical ring, and fusiform ascospores, conical at the lower end. Based on morphology and phylogenetic analyses, the two fungal strains are described as a distinct new genus <em>Pseudoconiocessia</em>, within Coniocessiaceae. <em>Pseudoconiocessia</em> is introduced here with <em>Pseudoconiocessia xishuangbannaensis</em> as the type species.</span></span></span></p>2024-03-18T00:00:00+13:00Copyright (c) 2024 Phytotaxahttps://phytotaxa.mapress.com/pt/article/view/phytotaxa.641.2.5<strong>Two new species of <em>Anthurium</em> sect. <em>Urospadix </em>(Araceae) endemic to the <em>restinga </em>vegetation of Bahia, Brazil</strong>2024-01-04T20:40:42+13:00KARENA M.
