| ABSTRACT Planicapritermes Emerson, 1949 is a South American termite genus with two nominal species: Planicapritermes planiceps (Emerson, 1925) and Planicapritermes longilabrum Constantino, 1998. The soldiers of this genus are characterized by strongly asymmetrical mandibles. Planicapritermes planiceps was described from soldiers and workers, and P. longilabrum only from soldiers. Here we describe and illustrate workers of P. longilabrum based on specimens collected in Rondônia state, Brazil. We also present a comparison between workers and soldiers of P. planiceps and P. longilabrum, and describe the nest of P. planiceps. |

| All species of Macrostomus Wiedemann allied with Macrostomus pictipennis (Bezzi), are treated in the pictipennis species-group. Three currently recognized species and four new species are included, namely M. cervicicauda Smith, M. cysticercus Smith, M. manauara, sp. nov. from Brazil (Amazonas and Pará states), M. pacaraima, sp. nov. from Brazil (Roraima, Amazonas and Pará states), M. pictipennis (Bezzi), M. smithi, sp. nov. from Guyana and Brazil (Roraima State) and M. utinga, sp. nov. from Brazil (Pará State). All primary types were examined and a key to species is presented. |

| A new species of the genus Cerqueirellum Py-Daniel, 1983 (Diptera: Simuliidae) is described. The adults are similar to the species C. oyapockense (Floch & Abonnenc, 1946) and C. roraimense (Nunes de Mello, 1974), of which the females are similar, and the males present discrete differences. The main differences of this new species to others of the genus Cerqueirellum are the integument of the larva recovered from stout spines and long cephalic trichomes in the pupa. Some females were infected with Mansonella ozzardii (Manson, 1897) (Nematoda, Onchocercidae) and probably transmit mansonelliasis in the Ituxi river, state of Amazonas, Brazil. |

| ABSTRACT Identification keys are essential to properly recognize taxa, and a photographic key not only addresses that issue but can also attract the interest of the general public if designed correctly. Syrphidae is one of the largest families of Diptera, and the Brazilian Amazon holds more taxon records from this family than currently reported. The aim of the current study was to provide an updated photographic identification key, of easy use and access, to the genera of Syrphidae (Diptera) from the Brazilian Amazon region, and identify previously unrecorded taxa. Through a literature review and study of collection material from several institutions, I found 36 new taxon records for the Brazilian Amazon (15 are first records for Brazil) and provided a... |

| ABSTRACT The first record of Phyllanthus chacoensis for the Brazilian Amazon is presented, based on a specimen from Rondônia state. The species can be recognized by its cauliflorous inflorescence, staminate and pistillate flowers with 4 sepals, devoid of a floral disk, 4 stamens, 2-carpellary ovary, drupaceous, ellipsoidal fruits, with one seed per locule. The species was previously known only from the central-western and northeastern regions of the Caatinga and Pantanal domains in Brazil. We provide a list of synonyms, a detailed description, an updated geographic distribution map in Brazil, data on habitat and conservation status, illustrations of its reproductive characters, and detailed photographs. We also propose a lectotype for the species. |

| ABSTRACT Orthomene comprises four species distributed from Central to South America, of which three occur in phytogeographic domains of Brazil. In Brazil, Amazonia is the main center of diversity for the genus. This work is a taxonomic treatment of Orthomene in Brazil and involved analyzing field collections (between January 2017 and July 2018), types and botanical specimens from 32 national and foreign herbaria. The three species in the study area are Orthomene hirsuta,Orthomene prancei and Orthomene schomburgkii. The latter is the most common and widely distributed species of the genus in the country. An identification key, descriptions, illustrations, distribution data, and additional comments for each species are provided. |

| ABSTRACT Dihoplotermes, a previously monotypic genus, is now composed of two species. Dihoplotermes taurus sp. nov., a new Termitinae termite species, is illustrated and described based on morphological characters from soldiers, workers, and imago. The new species is distinguished from Dihoplotermes inusitatus Araujo by having a spine-like protuberance with blunt apex on the postmentum, the presence of a spine on the gizzard and the absence of dimorphic soldiers. Furthermore, the internal morphological characteristics of a Dihoplotermes worker are described for the first time. Both internal and external morphological characters were used to improve the characterization of the species. |

(type locality: Colombia, Amazonas, Leticia, Amacayacú); L.bulbosiforceps sp. n. (type locality: Peru, Cuzco); L. cuzcoensis sp. n. (type locality: Peru, Cuzco); L. marabaensis sp. n. (type locality: Brasil, Pará, Marabá, Serra Norte); L. pilosiforceps sp. n. (type locality: Brasil, Pará, Oriximiná, Rio Trombetas); L. pilosipenna sp. n. (type locality: Peru, Cuzco); L. squamiforceps sp. n. (type locality: Colombia, Amazonas, Leticia). The Amazon Basin is the second most rich world area for species of Lachesilla. |

| Dichaea is the largest genus of the subtribe Zygopetalinae and holds it's the highest species diversity in South America. Therefore, this study aims to describe a new species of Dichaea, which occurs in northern Brazil, Dichaea bragae Valsko, Krahl & Holanda. The new species was collected in the north of Manaus in an area of ombrophilous forest and flowered when cultivated. The epithet honors Dr. Pedro Ivo Soares Braga (in memoriam), orchidologist who conducted several studies in the Brazilian Amazon. This new species show a affinity with Dichaea tenuis C. Schweinf., however it is differentiated both vegetatively and on labellum morphology. |

| ABSTRACT Diplodon granosus was one of the first freshwater mussels to be described for South America. However, the status of the species was confusing for a long time, receiving different taxonomic treatments. In this paper, we redescribe the shell, with new data on the soft parts and information on the distribution and conservation of D. granosus, a rarely recorded species. The shell is thin, not inflated; the macrosculpture is composed only by granules that cover the whole shell, not forming bars; the microsculpture comprises short spikes. In the soft parts we highlight the few, weak and irregularly distributed lamellar connections of the outer demibranch and some features of the stomach, such as the distally enlarged minor typhlosole. There are records... |

| ABSTRACT Pintomyia (Pifanomyia) duckei Oliveira, Alencar and Freitas sp. n. from Adolpho Ducke Reserve, Manaus, Amazonas state, Brazil, is described and illustrated based on three male specimens, the holotype and two paratypes. The paratypes have abnormalities in the external genitalia, one with asymmetric bilateral anomaly (different anomalies in each of certain paired structures) and the other with unilateral anomaly (anomaly in one of the paired structures). The new species probably belongs to the Serrana Series, integrating the list of the species whose males possess gonostylus with two stout spines (one apical and other subapical), as well as a small and very thin spine on the inner surface of the basal half. |
