A New Species

In May 2020, a new taxon of Euphorbia, Euphorbiaceae was collected from a dry hillside of Dongsheng District, Ordos City, Inner Mongolia. The morphological characteristics of the specimens analyzed differ from those of the known Euphorbia species from this region; therefore, we suspected this may be a new species, and we set to analyze the ITS2 sequences of some Euphorbia species. The results show that the new taxon belongs to the sect. Esula of Euphorbia subg. Esula. It is similar to Euphorbia esula (description from Flora of China) but does not belong to the same species. Concomitantly, plant morphological data and pollen morphology results show significant differences between the new taxon, E. esula and E. caesia, a finding that supports the delimitation of this new taxon, which is named Euphorbia mongoliensis in accordance with its geographical distribution.

ABSTRACT We describe and illustrate a new species of Coccoloba (Polygonaceae), named Coccoloba gigantifolia, from the Brazilian Amazon. It resembles Coccoloba mollis Casar, but differs from the latter species by its much larger leaves in the fertile branches. The species has only been recorded in the Madeira River basin, in the states of Amazonas and Rondônia, in the central and southwestern Brazilian Amazon. The description was based on herbarium material, cultivated plants, and individual trees in their natural habitat. We provide illustrations, photographs, and an identification key with morphological characteristics that distinguish the new taxon from the other two related taxa of the Coccoloba sect. Paniculatae, as well as comments on the geographic distribution and conservation status of the species.

Oreocharis brachypodus is described and illustrated as a new species from Guizhou, China. The new species is similar to Oreocharis villosa. However, the new species is readily distinguished from the latter by cymes not branched, 1–4-flowered, larger and pronounced gibbous corolla (2.2–2.5 cm long), ovary ca. 1 cm long, with 4 ribs prominent, style ca. 0.7 cm long, and thecae confluent. Comments on affinities, geographical distribution, ecology, phenology and conservation status of the new species are also provided.

Chilean Population

Studies conducted over the last few years in Andean boreal Patagonia along the border of Argentina and Chile (36°50’S–37°53’S) have shown that its reptile diversity is comprised of several endemic lizards. Increasing research has led to recognize a number of cryptic iguanian species from previously named taxa. In this area is common the only known Chilean population of the Patagonian Liolaemus rothi, considered as a polymorphic species with wide geographical distribution. In this paper, we provide evidence to support the hypothesis that such population represents a new taxon, herein described as Liolaemus hermannunezi. This new species occurs in the southeastern areas of Laguna del Laja, in the Los Barros and Río de Los Pinos basins of Antuco Volcano (1428–1521 m) in the Bio Bio Region. Liolaemus hermannunezi is closely related to L. rothi, from which is significantly differentiated by molecular variables. In addition, this new species appears to be related to L. loboi and L. sagei, from which differs in having a smaller body size, a distinctive colour pattern and an isolated geographical distribution. Liolaemus hermannunezi is known from the boreal Patagonia of Chile, whereas L. loboi, L. rothi, and L. sagei are endemic to Argentinean Patagonia. The new species is a member of the boulengeri clade, diagnosed by the presence of a patch of abruptly enlarged scales on the posterior medial surface of the thigh, a character that is more conspicuous in adult males. Finally, a phylogenetic hypothesis for 67 Liolaemini taxa based on DNA sequences is presented

Amyris jorgemeavei from the state of Oaxaca, Mexico, is described and illustrated. The new taxon is compared with A. carterae and A. madrensis, species with similar morphological characteristics. It is however easily differentiated from these two by having glabrous leaves and floral parts, a lobed nectar disc, and it is known only from southwestern Mexico. A comparative table and a distribution map of the three species are included.

During an investigation into the microfungi on Dracaena fragrans in Thailand, a saprobic taxon belonging to Glomerellaceae was collected. Based on morphological characterization and combined phylogenetic analyses of ITS, GAPDH, CHS-1, ACT and TUB2 sequence data from the sexual and asexual morphs our taxon was identified as a new species of Colletotrichum. Colletotrichum dracaenigenum sp. nov. is introduced here with a full description, colour photographs of morphological characteristics and a phylogenetic tree to show the placement of the new taxon in the gloeosporioides species complex.

A new species of Chiroderma Peters, 1860 (Chiroptera, Phyllostomidae) from the State of Piauí in Northeastern Brazil is described based on mensural analysis, morphological data and geographical distribution. It is most similar morphologically to C. doriae Thomas, 1891 but differentiated by a smaller body size and by differences in cranial traits. In comparison to other members of the genus, the new species can be distinguished by a combination of characters, including size of the body, conspicuousness of facial and median dorsal stripes, ear length, and variation in cranial and dentition traits.

A New Species

Obba thailandica sp. nov. is described and illustrated from northern Thailand based on evidence from morphological characteristics and molecular data. The species produces annual, resupinate, white and waxy fresh basidiocarps, which become bone hard when dry, and has a very thin subiculum (< 0.1 mm), tomentose tube openings, weakly dextrinoid hyphae, variably shaped cystidioles, thin-walled and subglobose to globose basidiospores (4.8–5.8 × 4–4.9 μm) mostly with a large guttule and grows on charred pine wood. The new taxon is rather similar to O. rivulosa in both morphology and ecology, but O. rivulosa has fragile tubes when dry, a thick subiculum (up to 1 mm wide), smooth tube openings, indextrinoid hyphae, rhomboidal to irregular rosettes crystals on the tramal hyphae and long basidia (16–27 × 6–9.5 µm). In the phylogeny inferred from an ITS dataset, the new species forms a distinct lineage in the Obba clade and is closely related to O. rivulosa.
