Abstract Piresia, a small genus of herbaceous bamboos, has a geographical disjunction between the Caribbean and northern/western South America and the north-eastern Atlantic Forest in Brazil. Piresia leptophylla is reported from western Amazonia (WA) and the north-eastern Atlantic Forest (NAF), but its occurrence in western Amazonia is questionable. Using an integrative approach, we combined traditional morphological analysis, anatomy and niche modelling. The results revealed few macromorphological differences between WA and NAF specimens (only plant height, leaf length, lodicule dimensions, shape and position), contrasting with consistent differences in leaf anatomy (macrohairs and cruciform silica bodies in the costal zone of the adaxial/abaxial leaf surfaces, crenate silica bodies on the abaxial leaf surface, lack of panicoid hairs on the abaxial leaf surface, bicellular microhairs and lobed papillae over the abaxial leaf surface, and sparse but elongated fusoid cells in the mesophyll of WA specimens) and in niche patterns. The anatomical/micromorphological characters suggest environmental adaptations to the Amazonian and ‘restinga’ forests, respectively. We therefore propose the segregation of the WA populations into a new species, Piresia tenella sp. nov. We provide a formal description, photographs, a line illustration, a distribution map and discussion of the conservation status for the new species.

A New Species

A new species, Eucalyptus fusiformis Boland et Kleinig, from the north coast of New South Wales is described. Its taxonomic position is in E. subgenus Symphyomyrtus series Paniculatae following the informal classification of eucalypts proposed by Pryor and Johnson (1971). E. fusiformis is characterised by its flowers, fruits and adult leaves. In the bud the staminal filaments are fully inflected while the androecium has outer staminodes and the anthers are cuboid and adnate. The fruits are narrow, often truncate fusiform, tapering into long slender pedicels. The adult leaves are dull grey, concolorous and hypoamphistomatic. The species resembles the more numerous and often co-occurring ironbark E. siderophloia which has similar adult and seedling leaves. The volatile oils of both species are very similar. The ecology, distribution, taxonomic affinities and conservation status are discussed.

A New Species

We here describe and illustrate Begonia tadungensis (B. sect. Platycentrum), a new species from southern Vietnam. The new species is most similar to B. albopunctata in having broadly ovate leaves, three free styles, 4-loculed ovary, and berry-like fruits with a beaked apex, but differs mainly in having a glabrous abaxial leaf surface (not densely red pubescent), and fruits with gray puberlous hairs (not white papillose). It is also similar to B. pendens in its broadly ovate leaves and monoecious breeding system, but differs in having 6 tepals in the pistillate flowers (not 5) and 4-loculed ovaries (not 3-loculed). Information on ecology, conservation status, and a further comparison of characters with these two similar species is also provided.

Vernonia monocephala subsp. irwinii is a member of the genus Lessingianthus and is hereby transferred to that genus with a new status and a new name, L. semirii. It differs from L. monocephalus by its subsessile to petiolate (vs. sessile) leaves, largely attenuate (vs. rounded to attenuate) leaf bases, adaxial leaf surfaces drying black (vs. greenish), tomentose to velutinous (vs. villous) abaxial leaf surface and stem indument, and number of florets per head (up to 120 vs. up to 210). Both species are native to provinces of the Cerrado Domain, but they do not occur sympatrically: L. semirii is restricted to the North-eastern floristic province (Bahia, Maranhão, Tocantins and Pará states) and northern portion of the Central-western floristic province (Mato Grosso state), whereas L. monocephalus occurs in Distrito Federal and Goiás states in the Central-western, Central and South-eastern floristic provinces. Lessingianthus semirii is hereby described and illustrated for the first time; a distribution map is provided and affinities of this species are discussed.

Abstract— Reinterpreting the morphology of two taxa proposed by Victoria C. Hollowell in the 1980s and not formally published, we describe here three new species of Eremitis, a Neotropical genus of herbaceous bamboos (Poaceae, Bambusoideae, Olyreae), which is endemic to the Brazilian Atlantic Forest. Two of them, Eremitis grandiflora and E. paucifolia, are endemic to Espírito Santo state. Eremitis victoriae occurs in southern Espírito Santo and has also been documented for southern Bahia. Eremitis grandiflora is similar to the smallest species of the genus, but can be differentiated by its decumbent culms with scale-like leaf blades and its longer gynecandrous whorls. Eremitis paucifolia is characterized by its leafy culms with a reduced number of leaves [5‐6(‐7)] compared to other species of the genus. Eremitis victoriae is distinguished from the congeneric species mainly by its abaxially glaucous leaf blades. Here, we provide an identification key to all described species of Eremitis that occur in Espírito Santo, as well as a map with their geographical distribution. All three new species are illustrated with both line drawings and photographic images, and an informal assessment of their conservation status is presented.

Eremitis Döll is a herbaceous bamboo genus (Poaceae, Bambusoideae, Olyreae) belonging to subtribe Parianinae that currently includes seven species. During fieldwork conducted throughout the geographic distribution of the genus, two new species with blue iridescent leaves, E. berbertii F. M. Ferreira & R. P. Oliveira and E. fluminensis F. M. Ferreira & R. P. Oliveira, from the Brazilian Atlantic forest, were collected and are here described and illustrated. Eremitis berbertii is endemic to the Private Reserve of Natural Heritage (Reserva Particular do Patrimônio Natural [RPPN]) Serra do Teimoso, in Bahia State, and E. fluminensis is restricted to the south of Rio de Janeiro State. In this study, micromorphological features of the leaf epidermis of the new species were compared with other species of the genus that display blue iridescence in their leaf blades. Variegated leaves are recorded for the first time in herbaceous bamboos. Comments on habitat, distribution, and conservation status of the new taxa are provided, as well as a revised identification key to all species of the genus described so far.

In this paper we describe and illustrate Caraipa pilosa, a new species from the Venezuelan Guayana endemic to the Parú massif, morphologically similar to C. aracaensis, a species endemic to Serra do Aracá in Amazonas, Brazil. These two species have similar leaf type (conspicuously coriaceous, the margins revolute and with conspicuous pubescence on the abaxial leaf surface), but in Caraipa pilosa the trichomes are longer (≤1 mm) than in C. aracaensis (≤0.1 mm) and present in young stems, upper leaf surface (especially in young leaves), inflorescence axes, sepals, ovaries, and fruits. Also, in Carapia pilosa, leaf blades are consistently larger than in C. aracaensis. Caraipa pilosa is only known from the montane forest of Cerro Parú, and its conservation status is Least Concern (LC, following the IUCN Red List categories).

Four new species of the Palaearctic crangonyctid amphipod genus Lyurella Derzhavin, 1939 (Crustacea: Amphipoda: Crangonyctidae), L. mikhailovi sp. n., L. fanagorica sp. n., L. fontinalis sp. n. and L. asheensis sp. n., are described based on an integrative approach from the subterranean habitats of the southwestern foothills of the Greater Caucasian Ridge (the north-eastern Black Sea coast). Despite the relative proximity of the habitats, the interspecific genetic divergence (by COI mtDNA gene marker) between the newly outlined Caucasian species of the genus varied from 11 to 21%, demonstrating a long-term isolation and lack of gene flow for at least 3–7Mya, starting from the Pliocene. The lowest genetic divergence between L. shepsiensis Sidorov, 2015 and L. asheensis sp. n., estimated as 4%, is also considered species-specific due to the presence of distinct morphological differences. We discuss the phylogeny, morphology, and distribution and provide a key for all known species of Lyurella. DNA barcoding data for all species, including the type species of the genus, Lyurella hyrcana Derzhavin, 1939, are presented for the first time.

A New Species

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.
