Abstract Dendrophthora and Phoradendron are neotropical genera of mistletoes belonging to the tribe Phoradendreae. The phylogenetic relationships between these two genera are still not entirely understood and, morphologically, Dendrophthora differs from Phoradendron solely by the presence of one, anther locule, as opposed to two in the latter. This study provides a synopsis of species of both genera for Brazil, where we revised all the names with Brazilian types or cited for the country. A total of 173 names were evaluated and the presence of 44 taxa in Brazil was confirmed: three species of Dendrophthora and 41 of Phoradendron. An identification key for the confirmed taxa is proposed and taxonomic comments are elaborated, along with an iconography, geographic distribution of the taxa, and original illustrations and photos of some species. Six new synonyms are proposed in Dendrophthora, and 12 in Phoradendron; 27 names are lectotypified.

Taxonomic studies of Mimosa subser. Polycephalae revealed a new species and indicated the need for taxonomic and nomenclatural adjustments in the group. Mimosa pseudoracemosa is described and illustrated as a new species from Goiás State in central-western Brazil. We discuss its geographic distribution, environmental preferences, phenology and conservation status and compare it with the morphologically similar M. pseudoradula and M. flavocaesia. A new status for M. pseudoradula var. detonsa and a new name are proposed (= M. detonsa), including M. pseudoradula var. anapolitana and M. pseudoradula var. crystallites as its synonyms, as well an updated circumscription for M. pseudoradula without the admission of varieties. We also present descriptions, images, maps, comments on their distributions and morphological relationships, flowering and fruiting periods, and conservation statuses. In addition to the morphological and geographic discontinuities of the aforementioned taxa, their trichome micromorphology supported the establishment of the new species, as well as the taxonomic decisions involving M. pseudoradula.

Abstract We present the taxonomic treatment of Convolvulaceae for the Meruoca Massif, located in the Northwest region of the Ceará state, where there are remnants of Tropical Pluvial Sub-deciduous Forest (Dry Forest) and Tropical Pluvial-Nebular Rainforest (Wet Forest). The present study was based on the morphological analysis of specimens collected in the field and from the collections EAC, HUEFS, HUVA, PEUFR, and SPF. We recorded 24 species distributed in four genera: Ipomoea (18 species), Jacquemontia (three species), Distimake (two species), and Camonea (one species). We report the first records of I. cearensis for Atlantic Forest and I. aristolochiifolia to the state of Ceará. The taxonomic treatment includes identification key, morphological descriptions, geographic distribution, taxonomic and ecological comments, the period of flowering and fruiting, and photos and illustrations of the diagnostic characters.

ABSTRACT A taxonomic revision and phylogenetic analysis were completed for Dasyloricaria . The genus includes three valid species: D . filamentosa and D . latiura previously included in the genus, and a new species described herein. Dasyloricaria have a restricted trans-Andean distribution, with D . filamentosa occurring at the lower and middle Magdalena, lower Cauca, and Sinu in Colombia, and lago Maracaibo basin in Colombia and Venezuela; D . latiura in the Atrato and the Tuyra basins in Colombia and Panama, respectively; and the new species in the upper and middle Magdalena basin in Colombia. New synonyms for D . filamentosa and D . latiura are proposed, and a lectotype is designated for the latter. Dasyloricaria is herein recognized as monophyletic, with D . filamentosa as the sister group of D . latiura , and the new speciesas sister to that clade. Spatuloricaria is hypothesized to be the sister group of Dasyloricaria based on synapomorphies of the neurocranium, branchial arches and external morphology features. The subtribe Rineloricariina was partially corroborated through the phylogenetic analysis. An identification key for the species of Dasyloricaria is provided.

A new Hasemania species is described from the headwaters of the rio Uberaba, rio Grande basin, State of Minas Gerais, Brazil. The new species is distinguished from its congeners by a combination of a black, vertically-elongate humeral spot, a single ossification in the position primitively occupied by infraorbitals four and five, four teeth on the inner series of premaxilla, and scales covering the anal-fin base. Hasemania crenuchoides is redescribed and its known geographic distribution is extended; it can be differentiated from other species of the genus by the combination of a black vertically-elongate humeral spot, ii,8 dorsal-fin rays, 11-14 branched anal-fin rays, the presence of separate infraorbitals four and five, and the presence of scales covering the anal-fin base. Phylogenetic relationships of H. crenuchoides and the new species within Hasemania are discussed.

The Agrilus cyanescens species-group of jewel beetles is defined to include seven species, three of which are newly described: A. dali Jendek sp. n. (China: Yunnan), A. zhongdian Jendek sp. n. (China: Yunnan) and A. arsenevi Jendek sp. n. (Russia: Primorsky Kray). Three new synonyms are proposed for A. cyanescens (Ratzeburg, 1837) (= italicus Obenberger, 1920 syn. n.; = cockerelli Fisher, 1925 syn. n.; = pooli Théry, 1936 syn. n.). Each member of the group is illustrated and an identification key to species, based on males, is provided.

The Asian species of the genus Pachysternum Motschulsky, 1863 are revised and redescribed. Three new species are de-scribed: Pachysternum kubani sp. nov. (Laos, China: Sichuan), P. rugosum sp. nov. (China: Gansu, Shaanxi) and P. san-dacanum sp. nov. (Malaysia: Sabah, Sarawak). Three new synonyms are established: Megasternum gibbulumMotschulsky, 1866 and Pachysternum sibiricum Kuwert, 1890 are junior synonyms of Pachysternum haemorrhoumMotschulsky, 1866; Pachysternum nigritum Jia, Wu & Pu, 1998 is a junior synonym of P. stevensi Orchymont, 1926.Pachysternum keralense Hebauer, 2002 is transferred to the pilocnemoides group of the genus Australocyon Hansen,1990. Megasternum japonicum Shatrovskiy, 1989 is resurrected from the synonymy with M. gibbulum and considered asa valid name. Lectotypes are designated for the following species: Pachysternum apicatum Motschulsky, 1863, P. curva-tum Orchymont, 1925, P. haemorrhoum Motschulsky, 1866, P. nigrovittatum Motschulsky, 1863, P. sibiricum Kuwert,1890, Megasternum gibbulum Motschulsky, 1866 and M. distinctum Sharp, 1873. All Pachysternum species are diag-nosed, relevant morphological characters are illustrated, and an updated identification key is provided. Pachysternum api-catum is interpreted as a polymorphic species exhibiting high geography-based variation and possibly consisting of somesibling taxa; diagnosing of these taxa requires more material and additional (ideally molecular) characters and is therefore left unresolved at the present time.

Anupdated circumscription and a taxonomic treatment of Chamaecrista sect. Absus subsect. Absus ser. Rigidulae is presented based on the results of previous phylogeny study where the series has emerged as monophyletic with exclusion of two species (C. brachyblepharis and C.ciliolata) and inclusion of two others species (C. botryoides and Ch. sincorana) in its circumscription. This revision resulted from consulting the specialized literature, analyzing of about 1400 collections from national and foreign herbaria. In this new circumscription, the series becomes the largest series of the genus with 32 species endemics to Brazil and distributed mainly in the Brazilian Central Plateau. Two new records in Brazilian states were reported, one to Bahia (Ch. feliciana) and two to Minas Gerais (Ch. benthamiana, Ch. rupestrium); an identification key of the species, morphologic descriptions, notes on taxonomy and geographic distribution of the taxa, conservation status, as well as illustrations and images of diagnostic characters are presented. In addition, the species typification remains updated with all categories indicated first with their respective barcodes.

We report the first record of Voyria caerulea from the state of Maranhão, northeastern Brazil. A fertile specimen was collected in a gallery forest during the rainy season, within the boundaries of the municipality of São Raimundo das Mangabeiras. This find contributes to the knowledge on the micoheterotrophic flora of Maranhão and expands the geographic distribution of this species in Brazil. We also present a taxonomic description, illustrations, an occurrence map of the newly found population, and an identification key for all the species of Voyria that occur in Maranhão.
