It supports countless thousands of species, as well as 30 million people. © Brent Stirton / Getty Images / WWF-UK © Brent Stirton / Getty Images The Amazon is the largest rainforest on Earth. It’s famed for its unrivalled biological diversity, with wildlife that includes jaguars, river dolphins, manatees, giant otters, capybaras, harpy eagles, anacondas and piranhas. The many unique habitats in this globally significant region conceal a wealth of hidden species, which scientists continue to discover at an incredible rate. Between 1999 and 2009, at least 1,200 new species of plants and vertebrates have been discovered in the Amazon biome (see page 6 for a map showing the extent of the region that this spans). The new species include 637 plants, 257 fish, 216 amphibians, 55 reptiles, 16 birds and 39 mammals. In addition, thousands of new invertebrate species have been uncovered. Owing to the sheer number of the latter, these are not covered in detail by this report. This report has tried to be comprehensive in its listing of new plants and vertebrates described from the Amazon biome in the last decade. But for the largest groups of life on Earth, such as invertebrates, such lists do not exist – so the number of new species presented here is no doubt an underestimate.

It is distinguished from congeners by the following characters: dark bars on the body much thinner in the anterior half of the body than in the posterior half; 9+8 branched rays in the caudal fin; males with suborbital flap; lateral line ends above base of anal fin; caudal fin hyaline and dark bars on posterior half of body more than twice as wide as interspaces. Introduction Material and methods The genus Schistura is the largest genus within The specimens were either fixed in 4 % formal- the family Nemacheilidae, containing at present dehyde and later transferred into 70 % ethanol about 190 nominal species. They are typically for storage (ZRC 51724, ZRC 51725) or fixed and found amongst stones in moderately to fast flow- stored in 96 % pure ethanol (IAPG A2546-2552, ing streams and rivers in foothill to mountainous A2455-2459, A1129-1131, A1780, CMK 21704, habitats.

    Zootaxa 1150: 19–30 (2006) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ ZOOTAXA 1150 Copyright © 2006 Magnolia Press ISSN 1175-5334 (online edition) Akysis longifilis, a new species of catfish (Teleostei: Akysidae) from Myanmar HEOK HEE NG Fish Division, Museum of Zoology, University of Michigan, 1109 Geddes Avenue, Ann Arbor, Michigan 48109- 1079, USA. E-mail: [email protected] Abstract Akysis longifilis, new species, is described from the Sittang River drainage in Myanmar. It is a member of the A. variegatus species group and can be distinguished from congeners in the group (except for A. brachybarbatus, A. fuliginatus, A. pictus, A. prashadi, A. variegatus, A. varius and A. vespa) in having a smooth (vs. serrated) posterior edge of the pectoral spine. It is distinguished from A. brachybarbatus, A. fuliginatus, A. pictus, A. prashadi, A. variegatus, A. varius and A. vespa in having a unique combination of: length of adipose-fin base 25.7–31.1% SL, body depth at anus 9.7–13.6% SL, caudal peduncle length 18.3–23.2% SL, caudal peduncle depth 5.6–7.2% SL, head width 21.1–24.7% SL, nasal barbel length 67.4–96.4% HL, maxillary barbel length 123.2–159.6% HL, vertebrae 33–35, body with light saddle-shaped spots, and caudal fin forked. Key words: Siluriformes, Sisoroidea, Sittang River, South Asia Introduction Members of the akysid catfish genus Akysis are small catfishes with tuberculate skin and a color pattern generally consisting of yellow patches or bands on a brown body. They are diagnosed by the anterior margin of the pectoral spine with a notch visible dorsally and the nasals with expansions beyond the canal-bearing region (de Pinna, 1996), and are found in fast-flowing streams and rivers in Southeast Asia [more specifically in the area bordered by the Irrawaddy River drainage to the west, the Barito River drainage to the east, the Lancanjiang (upper Mekong) drainage to the north and the Citarum River drainage to the south].

One of the most visited caves in Ecuador is Jumandi Cave (0o 52.5028’ S, 77o 47.5587’ W). Jumandi Cave is 660 meters above sea level, 4 kilometers north of the village of Archidona, and 14 km north of the town of Tena in the Napo Province (Peck 1985). The cave is a single stream passage with side corridors. For a full description of the cave and a map see Peck (1985). Temperature inside the cave is 22 °C (Peck 1985). Bats and bat guano is scarce throughout the cave. A stream takes up most of the cave floor and brings in considerable plant debris that may be the food source for the aquatic invertebrate and vertebrate community. The most distinguished inhabitant of this cave is the endemic cave-adapted catfish, Astroblepus pholeter (Collette, 1962) (Collette 1962; Haspel et al. 2012). Stewart Peck, professor and entomologist at the University of Carleton, visited Jumandi Cave in 1984 and conducted a bioinventory. He reported the presence of 22 species of invertebrates as well as the Astroblepus catfish (Peck 1985). According to Peck, 19 species of the invertebrates were troglophiles and three were trogloxenes. The only reported troglobiont was Astroblepus pholeter (Peck 1985).

    A Guide to the Parasites of African Freshwater Fishes Edited by T. Scholz, M.P.M. Vanhove, N. Smit, Z. Jayasundera & M. Gelnar Volume 18 (2018) Chapter 2.1. FISH DIVERSITY AND ECOLOGY Martin REICHARD Diversity of fshes in Africa Fishes are the most taxonomically diverse group of vertebrates and Africa shares a large portion of this diversity. This is due to its rich geological history – being a part of Gondwana, it shares taxa with the Neotropical region, whereas recent close geographical affnity to Eurasia permitted faunal exchange with European and Asian taxa. At the same time, relative isolation and the complex climatic and geological history of Africa enabled major diversifcation within the continent. The taxonomic diversity of African freshwater fshes is associated with functional and ecological diversity. While freshwater habitats form a tiny fraction of the total surface of aquatic habitats compared with the marine environment, most teleost fsh diversity occurs in fresh waters. There are over 3,200 freshwater fsh species in Africa and it is likely several hundreds of species remain undescribed (Snoeks et al. 2011). This high diversity and endemism is likely mirrored in diversity and endemism of their parasites. African fsh diversity includes an ancient group of air-breathing lungfshes (Protopterus spp.). Other taxa are capable of breathing air and tolerate poor water quality, including several clariid catfshes (e.g., Clarias spp.; Fig. 2.1.1D) and anabantids (Ctenopoma spp.). Africa is also home to several bichir species (Polypterus spp.; Fig. 2.1.1A), an ancient fsh group endemic to Africa, and bonytongue Heterotis niloticus (Cuvier, 1829) (Osteoglossidae), a basal actinopterygian fsh.

    A Review of the Systematic Biology of Fossil and Living Bony-Tongue Fishes, Osteoglossomorpha (Actinopterygii: Teleostei)

Hilton1 and Sébastien Lavoué2,3 The bony-tongue fishes, Osteoglossomorpha, have been the focus of a great deal of morphological, systematic, and evolutio- nary study, due in part to their basal position among extant teleostean fishes. This group includes the mooneyes (Hiodontidae), knifefishes (Notopteridae), the abu (Gymnarchidae), elephantfishes (Mormyridae), arawanas and pirarucu (Osteoglossidae), and the African butterfly fish (Pantodontidae). This morphologically heterogeneous group also has a long and diverse fossil record, including taxa from all continents and both freshwater and marine deposits. The phylogenetic relationships among most extant osteoglossomorph families are widely agreed upon. However, there is still much to discover about the systematic biology of these fishes, particularly with regard to the phylogenetic affinities of several fossil taxa, within Mormyridae, and the position of Pantodon. In this paper we review the state of knowledge for osteoglossomorph fishes. We first provide an overview of the diversity of Osteoglossomorpha, and then discuss studies of the phylogeny of Osteoglossomorpha from both morphological and molecular perspectives, as well as biogeographic analyses of the group. Finally, we offer our perspectives on future needs for research on the systematic biology of Osteoglossomorpha. Keywords: Biogeography, Osteoglossidae, Paleontology, Phylogeny, Taxonomy. Os peixes da Superordem Osteoglossomorpha têm sido foco de inúmeros estudos sobre a morfologia, sistemática e evo- lução, particularmente devido à sua posição basal dentre os peixes teleósteos.
