Eight genera are included in the family Zoothamniidae, and at the present the data of the epibiotic species on crustaceans is not updated. Thus, the main goal of the present work is to provide the checklist of zoothamniids worldwide reported as associated to several groups of crustaceans, including some data of their geographic distribution, and also to provide the complete list of species of this peritrich group. We obtained all available data of family Zoothamniidae and checked their taxonomic status. Then we provided the complete list of species including those reported as epibionts on crustacean hosts. We obtained 156 species included in eight genera of Zoothamniidae, being 85 species recorded as symbionts on 86 species of hosts. Genus Zoothamnium contained the higher number (56) of epibiotic species on crustaceans, and genus Pseudohaplocaulus has not been reported for any crustacean. The reviewed data highlights the concentration of records in Europe, and stands out the need to amplify sampling and studies in the Southern Hemisphere. The main groups of crustaceans infested by zoothamniids are the amphipods, isopods and decapods.

Hyphodontia sensu lato, belonging to Hymenochaetales, accommodates corticioid wood-inhabiting basidiomycetous fungi with resupinate basidiocarps and diverse hymenophoral characters. Species diversity of Hyphodontia sensu lato has been extensively explored worldwide, but in previous studies the six accepted genera in Hyphodontia sensu lato, viz. Fasciodontia, Hastodontia, Hyphodontia, Kneiffiella, Lyomyces and Xylodon were not all strongly supported from a phylogenetic perspective. Moreover, the relationships among these six genera in Hyphodontia sensu lato and other lineages within Hymenochaetales are not clear. In this study, we performed comprehensive phylogenetic analyses on the basis of multiple loci. For the first time, the independence of each of the six genera receives strong phylogenetic support. The six genera are separated in four clades within Hymenochaetales: Fasciodontia, Lyomyces and Xylodon are accepted as members of a previously known family Schizoporaceae, Kneiffiella and Hyphodontia are, respectively, placed in two monotypic families, viz. a previous name Chaetoporellaceae and a newly introduced name Hyphodontiaceae, and Hastodontia is considered to be a genus with an uncertain taxonomic position at the family rank within Hymenochaetales. The three families emerged between 61.51 and 195.87 million years ago. Compared to other families in the Hymenochaetales, these ages are more or less similar to those of Coltriciaceae, Hymenochaetaceae and Oxyporaceae, but much older than those of the two families Neoantrodiellaceae and Nigrofomitaceae. In regard to species, two, one, three and 10 species are newly described from Hyphodontia, Kneiffiella, Lyomyces and Xylodon, respectively. The taxonomic status of additional 30 species names from these four genera is briefly discussed; an epitype is designated for X. australis. The resupinate habit and poroid hymenophoral configuration were evaluated as the ancestral state of basidiocarps within Hymenochaetales. The resupinate habit mainly remains, while the hymenophoral configuration mainly evolves to the grandinioid-odontioid state and also back to the poroid state at the family level. Generally, a taxonomic framework for Hymenochaetales with an emphasis on members belonging to Hyphodontia sensu lato is constructed, and trait evolution of basidiocarps within Hymenochaetales is revealed accordingly.

A New Species

Pareiorhaphis nasuta, a new neoplecostomine catfish of the family Loricariidae is described. The species was collected from headwaters of the rio Matipó, tributary of the upper rio Doce basin in State of Minas Gerais, Brazil. The new species is readily diagnosed from all remaining congeners by the longer snout and by the smaller orbital diameter. The new species is the first representative of the genus Pareiorhaphis discovered in the rio Doce basin, thus expanding its geographic distribution. A phylogenetic diagnosis for Pareiorhaphis is presented.

Eighteen Pteridophyte taxa in 15 genera are reported as new for the Territory of Amapá, Brazil. The collections area a result of a recent Projeto Flora Amazônica/Programa Flora expedition to that region, and update previous lists of taxa for Amapá.In 1975, Tryon and Conant publised a checklist of the ferns of the Brazilian Amazônia reporting 84 taxa for the Territory of Amapá. The paucity of records for Amapá reflects, at least in part, the amount of botanical exploration. The most complete list of taxa occurring in the Territory is an unpublished list of collection compiled by J. M. Pires. This compilation reports 118 taxas for the Territory of Amapá. The following list is intended to update both the Pires compilation an the Tryon and Conant checklist for the Territor. These records are the result of a Projeto Flora Amazônica/Programa Flora expedition to the region in the latter part of 1979. Species were included in this list is not reportes in the compilation of colections for Amapá, or listed as specifically occurrin in Amapá in the monographs and revisions consulted for listed as specifically occurring in Amapá in the monograohs and revisions consulted for identification (Evans, 1969; Kramer, 1957, 1978; de la Sota, 1960; Lellinger, 1972; Maxon & Morton, 1938; Scamman, 1960, Smith, 1971; Tryon, 1941, 1964).This list reports 18 taxa in 15 genera, increasing the number of taxa in Amapá from the 118 listed by Pires to 136. Most of the taxa reported here might have been predicted to occur in Amapá on the basis of their distribution records for surrounding regions.Each species is followed by a collection number. The collection number is that of D. F. Austin, C. E. Nauman, R. S. Secco, C. Rosario, and M. R. Santos except for four collections in which R. S. Secco was absent and B. V. Rabelo was present, and these are indicated after the collection number. Specimens are deposited in the herbaria of the Museu Paraense Emílio Goeldi, Belém, Brazil and the United States. The family system is essentially that used by Tyron and Conant.

AbstractThe recent increase in mammal inventories and the widespread use of pitfall traps as a major capture method in Brazil have increased the number of non-volant small mammal specimens in scientific collections, providing new information on natural history, geographical range, and taxonomic status of many marsupials and rodents. To date, however, little is known about the Brazilian species of the marsupial genus Thylamys : the number of species in the country is disputed, as are their names and geographic distribution. Thus, the aim of this study was to define the Brazilian species of the genus, delimiting their taxonomic status and distributional range. We provide qualitative and quantitative data on external and skull morphology for specimens housed in scientific collections. A study of the material available allowed us to recognize the occurrence of three species in Brazil: Thylamys karimii (Petter, 1968), T. macrurus (Olfers, 1818) and T. velutinus (Wagner, 1842). For each of these we provide redescriptions, a discussion of local and geographic variations, geographic distribution, taxonomy, age class differentiation, sexual dimorphism, and natural history.

A New Species

The Epicopeiidae is a small geometroid family distributed in the East Palaearctic and Oriental regions. It exhibits high morphological diversity in body size and wing shape, while their wing patterns involve in various complex mimicry rings. In the present study, we attempted to describe a new genus, and a new species from Vietnam, with comments on two assumed congeneric novel species from China and India. To address its phylogenetic affinity, we reconstructed the phylogeny of the family by using sequence data of COI, EF-1α, and 28S gene regions obtained from seven genera of Epicopeiidae with Pseudobiston pinratanai as the outgroup. We also compared the morphology of the new taxon to other epicopeiid genera to affirm its taxonomic status. The results suggest that the undescribed taxon deserve a new genus, namely Mimaporia gen. n. The species from Vietnam, Mimaporia hmong sp. n., is described as new to science. Under different tree building strategies, the new genus is the sister group of either Chatamla Moore, 1881 or Parabraxas Leech, 1897. The morphological evidence, which was not included in phylogenetic analyses, however, suggests its potential affinity with Burmeia Minet, 2003. This study also provides the first, although preliminary, molecular phylogeny of the family on which the revised systematics and interpretation of character evolution can be based.
