Abstract— A new species of Phyllanthus with phylloclades endemic to the State of Bahia is described here. Phyllanthus dracaenoides can be recognized for its peculiar habit that resembles a species of Dracaena, a very unusual height of up to 7 m, the plagiotropic phylloclades spirally arranged, and its vermiform cincinni. Notes on its habitat, taxonomic affinity, conservation status, geographic distribution, illustrations, and photographs are provided.

We describe, illustrate and compare three new Brazilian species of Senegalia from the Atlantic Forest domain: Senegalia atlantica, from Rio de Janeiro State; Senegalia rafinesqueana, from the state of Paraná; and Senegalia cupuliformis, from Bahia State. These species are morphologically most similar to S. tenuifolia and S. multipinnata, S. velutina, and S. kuhlmannii, respectively. Additionally, we provide an identification key to all Senegalia species that are morphologically similar to S. atlantica, S. rafinesqueana and S. cupuliformis and occur in the Atlantic Forest domain; we also provide comments on the geographic distribution and the flowering and fruiting period of S. atlantica, S. rafinesqueana and S. cupuliformis.

Zanthoxylum unifoliolatum Groppo & Pirani (Rutaceae), a new species from northeastern Brazil is here described and illustrated. To date, this species is known from a small number of collections from the state of Sergipe and considered endangered, given its restricted geographical distribution and the rapid deforestation of the Brazilian Atlantic Rainforest. Z. unifoliolatum can be readily distinguished from other Brazilian Zanthoxylum by its unifoliolate leaves, rather than pinnate leaves present in other Brazilian species of the genus A detailed description and illustrations of this new species are provided, as well as comments on the geographic distribution, phenology, generic relationships and conservation status. Additionally, a key to the species of Zanthoxylum from Northeastern Region of Brazil is provided.

Three species of Corethrella Coquillett, 1902 from the state of Amazonas, Brazil are described as new to science based on female adult specimens. Corethrella cabocla Feijó, Belchior, Marialva & Pessoa sp. nov. possesses four large setae on the frons between the ventromedial area of ommatidia, a wide clypeus with 1–4 setae, a wing with the apex of R2 basal to the apex of M2 and with a midlength band, and with the abdomen entirely dark brown. Corethrella ielemdei Feijó, Ramires, Lima & Pessoa sp. nov. possesses an elongated coronal suture, four large setae on the frons between the ventromedial area of ommatidia, a clypeus squarish with 42–43 setae, a wing with the apex of R2 basal to the apex of M1 and with a midlength band and dark scales on the basal and subbasal areas of the anterior margin, legs with dark scales, and with the abdomen entirely dark brown. Corethrella menini Feijó, Picelli, Ríos-Velásquez & Pessoa sp. nov. possesses wings with the apex of R2 basal to the apex of M2 and a midlength band, with darker basal scales along all veins, basal band dark scales on C, Sc, R, M, and Cu and the abdomen entirely dark brown. With the addition of the new species, the numbers of frog-biting midges described in the Amazon basin, Brazil and in Neotropical region are now 31, 49 and 80 species, respectively.

Abstract: A taxonomic treatment of Dalechampia species found in the Brazilian Amazon is presented. The study was based on an analysis of herbarium material (including historical and type collections), specimens collected in the field, and literature. Twenty-three species, distributed in five sections, are recognized. Dalechampia hastata is endemic to the Brazilian Amazon. Among the species surveyed, thirteen species are considered to be Least Concern (LC), and not currently at risk of extinction. Six species (D. attenuistylus, D. brownsbergensis, D. fragrans, D. hastata, D. megacarpa and D. olympiana) are Endangered (EN), three species (D. gentryi, D. heterobractea and D. tenuiramea) are Near Threatened (NT), and D. liesneri is listed with Deficient Data (DD). If we consider the occurrence only in Brazil of three species , the taxa can be designated as Vulnerable (VU). Dalechampia micrantha and D. parvibracteata are lectotypified. The lectotype of D. cissifolia, D. juruana, and D. pernambucensis is clarified. New occurrences are reported for some countries. An identification key, descriptions, taxonomic comments, illustrations, the conservation status, phenological data, and geographic distribution maps are provided.

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.

Inga (Fabaceae, mimosoid clade) is an important genus in the Atlantic Forest of Brazil where there are 44 species, 60% of which are endemic. In this work, we describe two new species of Inga (I. teresensis and I. tripa) from the Atlantic Forest and provide identification keys to the species of sections Vulpinae and Leptinga in the biome. Illustrations and comments about the geographic distribution, conservation status, phenology, etymology, and taxonomy of the new species are also included. Inga teresensis is only known from the state of Espírito Santo and is categorized as Critically Endangered (CR). Inga tripa occurs in coastal areas of the states of Bahia, Paraíba, Pernambuco, and Sergipe and is categorized as Learn Concern (LC).

Miconia is the largest genus of Melastomataceae in Brazil with more than 280 species, of which 120 are found in the Atlantic Rainforest. We present here a taxonomic treatment for the species of Miconia that occur in Espírito Santo, with morphological descriptions, geographic distribution, comments, photos and an identification key. We found 55 species, from which six were recently described (five endemic, M. capixaba, M. kollmannii, M. michelangeliana, M. ruschiana and M. valentinensis, and one with wider distribution, M. atlantica) and six are new records for the state (Miconia molesta, M. petroniana, M. staminea, M. stenostachya, M. valtheri and M. willdenowii). One species is presented here as a new species that will be described soon by other authors.

Abstract Three new species of the Cameroonian endemic freshwater crab genus Buea  Cumberlidge, Mvogo Ndongo, Clark & Daniels, 2019 are described. The new species were collected from protected areas in the Southwest region of Cameroon, the Korup and Bakossi National Parks and the Mt. Nlonako Ecological Reserve. These species are distinguished from each other and from the type species of the genus, Buea asylos (Cumberlidge, 1993), by a combination of morphological characters (carapace, thoracic sternum, chelipeds, and male first gonopod) and by partial sequences of three mitochondrial DNA genes (COI, 12S rRNA, and 16S rRNA). A phylogenetic analysis that included representatives of all other freshwater crab genera found in Cameroon recovered each of the new species as a well-supported distinct lineage. An identification key is also provided for the four species of Buea and the conservation status of the new species is discussed.
