The semi-arid region of Bahia is rich in species of Convolvulaceae, particularly in the genera Evolvulus, Ipomoea, and Jacquemontia. Field work in this region and taxonomic revision of Evolvulus section Phyllostachyi revealed the occurrence of three new species: Evolvulus altissimus, the tallest species of the genus, is a subshrub up to two metres tall; Evolvulus delicatus is a flexible branched species with small, stiff, and narrow pointed leaves; Evolvulus harleyi is a herb with glabrous or nearly glabrous leaves and a globose inflorescence. These three species are described and illustrated. Their similarities with allied taxa are discussed. A região do semi-árido da Bahia é rica em espécies de Convolvulaceae, particularmente os gêneros Evolvulus, Ipomoea e Jacquemontia. Diversos trabalhos de campo nesta região para a revisão taxonômica de Evolvulus seção Phyllostachyi revelaram a ocorrência de três novas espécies: Evolvulus altissimus, a mais alta dentre todas as espécies do gênero, é um subarbusto de até dois metros de altura; Evolvulus delicatus é uma espécie de ramos flexíveis com folhas pequenas, estreitas, duras e pontiagudas; Evolvulus harleyi é uma erva com folhas glabras ou quase glabras e inflorescência globosa. Estas três espécies são descritas e ilustradas. As relações com espécies próximas são discutidas.

Three new species of Alepia Enderlein from the semi-arid region of Bahia State, northeastern Brazil are described: A. montana sp. nov., A. arenivaga sp. nov., and A. fervida sp. nov. Currently, eight species of Psychodidae are known from the semi-arid area (including the three species here described)—a region characterized by a long dry season (6–11 months) and low precipitation levels (300–1000 mm/year). A list of the eight species of Psychodidae from the Brazilian semi-arid region is provided.

Mandevilla (Apocynaceae) is a neotropical genus which is well represented in Brazil. A recent taxonomic revision of the Brazilian species of Mandevilla subgenus Mandevilla included eight new species, one of them from the State of Pernambuco. Nevertheless, while preparing a survey of Apocynaceae from the Brazilian semi-arid region, a new species of the subgenus was recognised. Mandevilla catimbauensis Souza-Silva, Rapini & J.F.Morales is here described and illustrated. It is a twining plant with elliptic, glabrous leaves and hypocrateriform, purple flowers, known only from the Vale do Catimbau National Park, in the State of Pernambuco.

During a survey of Mucorales in fragments of an Atlantic Upland Forest inserted in the semiarid region of Pernambuco, Brazil, a specimen of Mucor was isolated from soil samples. The specimen was characterized based on morphological, physiological and molecular data (ITS and LSU rDNA regions). The isolate produces intensely branched sporangiophores commonly with between one and several septa with mostly applanate columellae. The sporangiophores were smooth-walled and varied in shape and size, while some were subglobose. The best growth was at 25°C but there was also good growth at 30°C. Based on the evidence of the analyzed datasets a new species of Mucor is proposed. A detailed description of the new specimen of Mucor from the Brazilian semi-arid region are provided.

This publication describes a new species of mosquito of the genus Toxorhynchites Theobald, 1901, subgenus Lynchiella Lahille, 1904. The species was found during an exploratory survey of the Culicidae in the Caatinga biome, which is unique to Brazil and characterized by a semi-arid climate. Because of the specific characteristics of the biome, it has potential for endemism of species that have adapted to its restrictive conditions, particularly those imposed by severe drought. The new species, Toxorhynchites (Lynchiella) caatingensis, is a phytotelmic species that inhabits bromeliads and has an unknown biology. It belongs to a species complex that is hereafter referred to as the Violaceus Complex, which comprises three species that are found in the same type of habitat and have similar morphology: Tx. caatingensis n. sp., Tx. mariae (Bourroul, 1904) and Tx. violaceus (Wiedemann, 1820). We describe the larva, pupa, adult female and male genitalia of specimens collected as larvae from the tank bromeliad Aechmea aquilega (Salisb.) Griseb. The main distinctive characteristics of the species are the presence of three lateral tufts on the terminal abdominal segments (one pale and the others dark); a blue midline on the abdominal sterna; in the pupa, the pentagonal shape of the paddle and the length of seta 6-V. PCR reactions were carried out for the mitochondrial CO1 gene fragment, which placed the new species in the subgenus Lynchiella. No match was found with any species recorded in GenBank. The subgenus now includes 17 species.
