Three new species of Hechtia from the Mexican State of Oaxaca are herein proposed as new: Hechtia flexilifolia, H. huamelulaensis, and H. nivea, from the physiogeographical provinces of Mixteca Alta, Costas del Sur, and Sierras Centrales de Oaxaca respectively. All three species are described and illustrated. Iconography provided features plants in habitat and under cultivation. An assessment of their conservation status sensu IUCN criteria is presented as well. We also discuss and illustrate the three growth patterns identified at this time in the genus.

Three new Magnolia species and a new record from Guatemala are described and illustrated. Two of the new species, M. javieri and M. oscarrodrigoi, are from Alta Verapaz Department and one, M. veliziana, is from Quiché Department. Additionally, M. faustinomirandae is newly reported for the flora of Guatemala. With this contribution, the number of native Guatemalan species increases from 11 to 15 species. An updated distribution map and a key to species are provided. Guatemala, particularly the north-wet-arc in the Maya Highlands, is now an important centre of diversification and endemism for Magnolia. The conservation status of the newly proposed species was unofficially assessed using IUCN criteria.

We propose that two populations previously referred to Hechtia epigyna, from the Mexican state of Hidalgo, represent a new species. Plants from the Hidalgo populations share the inferior ovary with Hechtia epigyna, an unusual trait in the genus, but they differ in their growth pattern (central vs. lateral inflorescence), characters of the adaxial foliar surface, petal color, and fruit position during dehiscence. We also provide a clarification on the typification of Hechtia epigyna. An assessment of the conservation status of the new species, Hechtia deceptrix following IUCN criteria resulted as CR (Critically Endangered).

Angraecoid Orchids

A recent large phylogenetic tree for the angraecoid orchids has shown that the Afrotropical genus Diaphananthe is polyphyletic with a small group of four species sister to Aerangis and Eurychone. These species have diagnostic morphological features different from any other angraecoids, notably an erose to fringed surface of the stipes and a calceiform viscidium. Diaphananthe quintasii, which has been regarded as conspecific with D. rohrii, is reinstated as a valid species and lectotypified, and Diaphananthe alfredii and Rhipidoglossum magnicalcar are put in synonymy under D. quintasii. To accommodate this group of species, along with three new taxa from West and Central Africa, a new genus named Kylicanthe is here described. Four new combinations are thus proposed, and K. bueae is chosen as the type species of the new genus and neotypified. Additionally, K. arcuata, K. cornuata, and K. perezverae are described as new species. An identification key for Kylicanthe and allied genera is presented, as well as one for the seven species in the genus. Notes on ecology and distribution in addition to a preliminary assessment of conservation status following the IUCN Red List are also provided.

We describe here Begonia medeiroii, a narrow endemic species from the Atlantic Rainforest. The conservation status of this species was assessed as critically endangered according to IUCN criteria. This species resembles to B. catharinensis and B. hirtella in some characteristics, differing among other features due the presence of adventitious vegetative buds on the adaxial surface of the leaves.

Three new Brazilian species of Aulonemia, a Neotropical woody bamboo genus, are described and illustrated: Aulonemia cincta, with its distinctive corky girdles; Aulonemia prolifera, characterized, among other Brazilian congeners, by its fimbriate leaf sheaths; and Aulonemia soderstromii, with its conspicuous cluster of spreading fimbriae. These new species all propagate by amphipodial rhizomes, an unusual feature shared with the Brazilian species A. aristulata, with which they are morphologically compared. Comments about habitat, distribution, phenology, and conservation status for each species are provided, as well as photographs taken in the wild.

A new species of Mimosa is described from the Atlantic Rainforest and ecotone with the Cerrado of southeastern Brazil, in the states of Minas Gerais, Rio de Janeiro and São Paulo: M. porrecta L. Jordão, M.P. Morim & Baumgratz (Leguminosae). Related to M. sensitiva, it shares morphological affinities with this species but differs in having porrect-stellate trichomes, a new type of trichome for the genus, on the stems, and the dendritic trichomes in the fruits. The conservation status was assessed, according to IUCN criteria, as Least Concern.

The main goal of this paper is to describe three new species of the genus Monospilus Sars, 1862 (Crustacea: Cladocera). Monospilus macroerosus sp. nov. differs from other species of the genus in several peculiar morphological traits, the most striking being the presence of a saw-shaped pecten of teeth on the postabdominal claw. This species inhabits semiterrestrial habitats (wet leaf litter on hydromorphic soil from gallery forest), exhibiting adaptations related to movement and food handling in this type of habitat. Monospilus brachyspinus sp. nov. inhabits truly aquatic habitats, where lives being associated with macrophytes and submerged leaves. It may be recognized by the postabdominal claw, which is armed with proximal spinulae modified in a short spine. In Monospilus sp., the proximal spinulae are modified in a long and slender spine. So far, Monospilus sp. occurs in southern South America, while Monospilus macroerosus sp. nov. and Monospilus brachyspinus sp. nov. occur in the Cerrado biome in Brazil, in the central portion of South America. Some conclusions about the conservation status of new species also are made.
