| Abstract: A new species of the genus Temnocephala Blanchard, 1849 from southern Brazil was found on two species of anomuran crustaceans, Aegla spinipalma Bond-Buckup & Buckup, 1994 and Aegla grisella Bond-Buckup & Buckup, 1994, the latter classified as a vulnerable species by the "Lista de Referência da Fauna Ameaçada de Extinção no Rio Grande do Sul. Decreto no 41.672, de 11 junho de 2002". The crustaceans were collected from a tributary creek of the Forqueta river, Perau de Janeiro, Arvorezinha and a tributary creek of the Fão river, Pouso Novo, Rio Grande do Sul, Brazil; both localities belong to the Sub-Basin of Forqueta River. The new species differs from seven other temnocephalans epibionts on Aegla Leach, 1820, by having the following... |

| Abstract: The current study describes a new species of Hyalella found in a natural pond at the municipality of Palmeira das Missões, located in the northwestern region of state of Rio Grande do Sul, southern Brazil. The new species differs from other species found in state of Rio Grande do Sul (Hyalella bonariensis, H. castroi, H. kaigang, H. imbya, H. georginae, H. gauchensis, H. montenegrinae and H. pampeana) in the type and number of setae on uropods, on telson and on the inner face of gnathopod 1. Besides, Hyalella palmeirensis is morphologically similar to H. curvispina, especially in the shape and number of setae of uropods. However, H. palmeirensis differs from H. curvispina in having only two simple setae on telson, the inner face of gnathopod 1... |

| Although ascidians form a conspicuous part of sessile assemblages in the Caribbean, no specialized inventories have been developed in Venezuela, except for a list of 15 species reported from Margarita Island (1984). Here we present the results of a taxonomic workshop held in the Universidad de Oriente, Boca del Rio, Margarita Island during April 20-25 of 2009, sponsored by the NaGISA-Caribbean Sea program. La Restinga National park was surveyed and we found 29 species belonging to 19 genera and 10 families. The most abundant colonial species were Clavelina oblonga, Aplidium accarense, Polyclinum constellatum, Distaplia bermudensis, Symplegma rubra, S. brakenhielmi, Botrylloides nigrum and Ecteinascidia turbinata. Among the solitary ascidians Phallusia... |

| Abstract: This work presents a floristic survey of the family Bignoniaceae in the Raso da Catarina Ecoregion, Bahia, Brazil, considered as the main family of the Brazilian forests lianas. The samples analyzed were collected from September 2012 to May 2014. The analyses were supplemented with botanical collections kept in the herbaria: ALCB, HRB, HUEFS, IPA and PEUFR. The identifications were made based mainly on specialized bibliographies, protologues, photos of type collections and consulting of the collections in the herbaria that were visited. 11 genera and 20 species of the family were recorded. Fridericia Mart. and Handroanthus Mattos were the most representative genera (5spp.), followed by Jacaranda Juss (2spp.). The other genera presented only one... |

| The endemic Neotropical long-horned caddisfly subgenus Notalina (Neonotalina) Holzenthal contains nine described species in two species groups, the brasiliana and roraima groups, from the Brazilian Southeastern and Amazonian regions, respectively. In this paper, a new species of Notalina in the brasiliana species group, from Chapada dos Veadeiros National Park, Goiás state, Brazil, is described and illustrated. The new species is easily recognized by the following character set: presence of two pairs of processes on abdominal segment X; presence of well-developed basoventral protuberances, mesally directed in ventral view; presence of triangle-shaped, acuminated mesoventral process on the inferior appendages; and phallic apparatus with flanges slightly... |

| Burseramyia braziliensis Maia & Fonseca, a new species of Cecidomyiidae (Diptera) that induces leaf galls on Swartzia langsdorffii Raddi (Fabaceae) is described and illustrated (larva, pupa, male and female) based on material from restinga areas of Bertioga, São Paulo, Brazil. Until now, Burseramyia was known from one galling species, Burseramyia burserae Möhn, 1960, restricted to El Salvador. The genus is easily recognizable by the shape of the gonostylus (equally subdivided into toothed and setose portions). The new species differs from the previously described species mainly in the number and shape of terminal papillae (larva), shape of hypropoct (male) and method of pupation. |

| Fernandesia meridionalis Rodrigues & Maia, a new genus and species of Cecidomyiidae associated with Myrciaria delicatula O. Berg (Myrtaceae) is described and illustrated (male, female, pupa, and larva) based on material from Rio Grande do Sul, Brazil. The new genus belongs to Lasiopteridi, but it cannot be placed to tribe. A key to the tribes of Lasiopteridi and one to the unplaced genera of Neotropical Lasiopteridi are given. |

| Bromeliaceae is one of the most relevant taxonomic groups of the Atlantic Forest, where the Brazilian southeastern region stands out as a center of diversity and endemism for many taxa of the family. We present a checklist of the 12 genera and 44 species of Bromeliaceae from the Pedra dos Pontões, in Mimoso do Sul municipality, Espírito Santo state, southeastern Brazil. The Bromelioideae (22 species) was the subfamily with most taxonomic diversity, followed by Tillandsioideae (18 species) and Pitcairnioideae (four species). We also report the first occurrence of four species (A. squarrosa, N. antoineanum, V. pseudoatra and V. pardalina) for the Espírito Santo state. Almost half of the taxa surveyed inhabit exclusively the vegetation associated to the rocky... |

| Abstract: Cyanobacteria and microalgae make up a very diverse group and exhibit diverse morphological, biochemical and physiological differences. The knowledge of these organisms that inhabit epicontinental waters in Brazil is extremely heterogeneous in relation to the geographic region and the taxonomic group. Taxonomically there is much more knowledge about the algae of the South and Southeast regions of the country than there is about the algae of the North and Central-West regions. Therefore, this research presents a revised and updated knowledge of the algae that occur in the National Park of the Chapada dos Guimarães (PNCG) and surrounding areas. Our area of study is located in the state of Mato Grosso, in the center-west region of Brazil. The... |

| Abstract: The acanthocephalan species Quadrigyrus torquatus Van Cleave, 1920 has been found in different hosts from South America, but recent papers have not focused on its morphology traits. Different species of Astyanax Baird & Girard, 1854 were collected with seine nets between January 2017 and October 2017 in Pintada Island, Lake Guaíba, Porto Alegre city (30º17’11’’S and 51º18’01”W), Rio Grande do Sul State, Brazil. Acanthocephalans found in cysts were processed according to the techniques for the group. Specimens of Q. torquatus were identified based mainly in the morphology of proboscis hooks and trunk spines, and by the measurements made using light microscopy. Supplemental observations on the morphology of Q. torquatus were made for the first... |

| Abstract This paper provides keys, illustrations, short descriptions, and voucher specimen citations for the ferns and lycophytes of Acre, Brazil. We recognize a total of 212 species in 66 genera and 28 families. Of these, the lycophytes are represented by 14 species, 4 genera, and 2 families, and the ferns by 8 varieties, 1 subspecies, 198 species, 62 genera, and 26 families. The total represents an increase of 22 species and two varieties compared to a checklist published in 2009. The six most species-rich genera are Adiantum (21 spp.), Asplenium (14), Selaginella (12), Trichomanes (11), Lindsaea, and Microgramma (9 each). None of the species treated here are endemic to Acre. A new combination is made for Meniscium chrysodioides Fée var. goyazense. |

| Abstract: Pithecopus rusticus is a newly described species, of which information on its natural history, vocalization and tadpole morphology are still lacking. Here, we describe the larval external morphology of P. rusticus from the type locality, in the municipality of Água Doce, state of Santa Catarina, southern Brazil, comparing it with that of other species of the genus Pithecopus and providing information on its natural history. Eggs from two spawns were collected and kept in the laboratory until hatching. The tadpoles of P. rusticus belong to the suspension-rasper guild. At Gosner stage 37, the tadpoles showed: body shape oval in dorsal view and triangular in lateral view; a tooth row formula of 2(2)/3(1); the third lower row six times shorter than... |
