A New Species

A remarkable new predatory species of Baetidae was collected in a relict patch of Amazonian savanna in Brazil. The feeding habit of the nymph of this new species is very rare in mayflies. Baetidae is composed of more than 900 species, but only 12 are considered to be predators; in South America, the only species recognized as a predator is Harpagobaetis gulosus Mol 1986. The objectives of this study are to describe Harpagobaetis brigada sp. nov., based on nymphs and to amend the diagnosis of the genus. The predatory habit of the nymphs of the new species was confirmed by gut-content analysis and by direct observations of behavior. Based on similar morphological adaptations, we hypothesized that Adebrotus lugoi Salles, 2010 possesses predatory habit. Harpagobaetis brigada sp. nov. can be classified as psammophilous, inhabiting a threatened stream in a relict patch of savanna in southern Amazonia. Based on these characteristics, we recommend evaluation of this new species to identify its conservation status and to contribute to the assessment of the state of conservation of the Brazilian fauna.

A New Species

Chionanthus is a genus from the plant family Oleaceae that is characterized by the presence of small calyces, 4-lobed corollas with petals arranged in pairs and held together by the filament bases, less commonly with a very short tube, two stamens in most species, and drupaceous fruits. As part of ongoing taxonomic studies of the Neotropical Oleaceae, we detected an undescribed species from Peru, that is here described and illustrated. Chionanthus chrysopetalus Cornejo ex Lombardi resembles C. implicatus and C. compactus, two species from northwestern South America, by the elliptic leaves. However, C. chrysopetalus can be separated by both taxa by the hispidulous indument, and yellow corollas, unusual features within the genus. In this study, I present a detailed description for the new taxon, notes on the phenology, geographic distribution, habitat, conservation status, and etymology.

A New Species

A new species of Piper L. (Piperaceae) from the eastern slopes of the Andes in Colombia and Peru, P. callejasii W. Trujillo & M. A. Jaram., is described and illustrated, and morphological comparisons with similar species are discussed. Piper callejasii is distinguished by its stigmas being sessile, rather than on a long style as in four similar species. Its conservation status is suggested to be Endangered.

High Diversity

Croton is one of the largest genera of Angiosperms, with a pantropical distribution and a high diversity in South America, where 500 of its species occur. Croton sect. Adenophylli, its largest section, is characterized mainly by the fruit columella with three terminal ascending and inflated appendices and is distributed across the Neotropics, with the Cerrado as one of its centers of diversity. One of the binomials in the section, Croton grandivelus, has been applied to a broadly circumscribed entity that is here treated as including three species, C. grandivelus sensu stricto, C. fulvus and C. insignis, the latter described as a new species. We present a taxonomic treatment for these three species with descriptions, photographs, an illustration for the new species, an identification key, distribution maps, and commentary on the taxonomy, geographical distribution, environmental preferences, conservation status, flowering and fruiting times, morphological relationships and notes about the leaf anatomy and micromorphology of foliar trichomes. As part of this process, we propose 23 new synonyms and 15 lectotypifications.

A new Waltheria species (Malvaceae) is described and illustrated here. Waltheria glabribracteata is known from ecotone areas in Brazil and Bolivia and can be readily distinguished from other Waltheria species by its bracts which are glabrous on the adaxial surface. This study presents a description of the new taxon, taxonomic comments, a distribution map, conservation status and an illustration.

Tecunumania stothertiae (Cucurbitaceae), a new species of herbaceous vine endemic to western Ecuador, is here described and illustrated. The discovery of Tecunumania stothertiae represents a new generic record for Ecuador and for South America. It represents a new southern extension for Tecunumania, a genus previously thought to be endemic to Mesoamerica. The conservation status of Tecunumania stothertiae is here assessed as Endangered.

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.

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

Scrophularia dianatnejadii Ranjbar & Rahchamani, a new species from Tehran Province in northern Iran, is described and illustrated. It is closely related to S. amplexicaulis Benth. and shares with it some diagnostic morphological characters such as habit, plant indument, phyllotaxy, and corolla shape and color. Both species are placed in Scrophularia L. sect. Mimulopsis Boiss. Macro- and micromorphological characters of the two are examined and compared. Pollen morphology of these species is investigated using SEM. Detailed descriptions, illustrations, distribution maps, and conservation status of both species are provided.

Silene lulakabadensis Heidari, F. Ghahrem. & Assadi is described as a new species from Zanjan Province, Iran. The new species is a dark green plant, perennial and woody at the base, that was collected on marl soil slopes at 2100 m. It is believed to be closely related to S. eriocalycina Boiss. from section Auriculatae (Boiss.) Schischk. but is a smaller plant, with much shorter internodes, and pinkish-white retuse to emarginate petals with very small or no scales. It is a very rare plant and its conservation status is assessed as Critically Endangered.
