Bulletin of the British Museum (Natural History)
A new catfish from Sierra Leone Gordon Jon Howes Zoology Department, British Museum (Natural History), Cromwell Road, London SW7 5BD A collection of freshwater fishes from Sierra Leone made by Dr A. I. Payne contained three specimens of a previously undescribed dwarf catfish. At first sight these small fishes (33-5- 36 mm SL) were thought to be the juveniles of a Synodontis species, but closer examination showed many significant differences. Furthermore, dissection of two specimens revealed that they were adult females, having ripe ovaries. In overall morphology the new catfish appears closer to members of the Mochokidae sensu lato than to those of any other siluroid family, (see p. 168). The possibility that these fishes belonged to the dwarf mochokid genus Microsynodontis was dispelled when comparisons were made with species of that genus. MOCHOKIELLA gen. nov. Fishes of a small size with a shallow body (depth 25-5-27-9 of SL). Head broad (almost equal to its length) with dorsal profile sloped, snout rounded, ethmoid with narrow rostral process. Nostrils widely separated, the posterior situated midway between the anterior nostril and the orbital rim. Anterior nostril tubular. Mouth small, lower lip developed only at the corners of the mouth. Premaxillary teeth short and conical, in a broad patch. Dentary teeth like those on the premaxilla, set in a broad semi-crescentic band. Vomerine teeth absent. One pair of maxillary and two pairs of mandibular barbels. The maxillary barbel long, reaching to the tip of the cleithral process. Outer mandibular barbel extending to halfway along the cleithral process, the inner reaching to the base of the pectoral spine. -

THE OBSERVATORY at LEOBO PRIVATE RESERVE Escape to A
THE OBSERVATORY AT LEOBO PRIVATE RESERVE Escape to a new kid of island…. OVERVIEW Surrounded by the diverse Waterberg region and overlooking the Palala Valley lies Leobo Private Reserve, an 8000 hectare (20,000 acre) estate encompassing rugged rocks, bushveld savannah, natural streams and an abundance of wildlife. Teeming with plains game, birdlife and a crocodile named Stevie, there are no time constraints, no rules (except safety) and no limits. It is one of only a handful of sole-use private reserves in South Africa allowing guests full access to the entire estate and all its facilities. Complete privacy and exclusivity is what Leobo Private Reserve is all about. Leobo, which is the name for chameleon in Northern Sotho is a fitting name for this reserve. Just like this enchanting creature, guests can change their day at the drop of a hat, pretty much do whatever they want and be accommodated by the most obliging staff! This magnificent, malaria-free destination provides the setting for an exclusive private house, The Observatory, designed by award-winning architects Silvio Rech and Lesley Carstens. The three-suite retreat, originally built as the owner’s family escape, is a chic villa that caters to the well-heeled, discerning traveller in search of absolute privacy, relaxation and a whole lot of adventurous fun! A maximum of 9 people (6 adults, 3 children) can be accommodated in 2 luxury bedrooms. A triple bunk room leads to a separate guest room for a nanny; this self- contained nursery space has a separate bathroom and kitchenette. Supplementary rooms for additional guests, family or nannies are available at the lodge on the reserve which sleeps a maximum of 18 (14 adults and 4 children). -

Phylogenetic Relationships of the South American Doradoidea (Ostariophysi: Siluriformes)
Neotropical Ichthyology, 12(3): 451-564, 2014 Copyright © 2014 Sociedade Brasileira de Ictiologia DOI: 10.1590/1982-0224-20120027 Phylogenetic relationships of the South American Doradoidea (Ostariophysi: Siluriformes) José L. O. Birindelli A phylogenetic analysis based on 311 morphological characters is presented for most species of the Doradidae, all genera of the Auchenipteridae, and representatives of 16 other catfish families. The hypothesis that was derived from the six most parsimonious trees support the monophyly of the South American Doradoidea (Doradidae plus Auchenipteridae), as well as the monophyly of the clade Doradoidea plus the African Mochokidae. In addition, the clade with Sisoroidea plus Aspredinidae was considered sister to Doradoidea plus Mochokidae. Within the Auchenipteridae, the results support the monophyly of the Centromochlinae and Auchenipterinae. The latter is composed of Tocantinsia, and four monophyletic units, two small with Asterophysus and Liosomadoras, and Pseudotatia and Pseudauchenipterus, respectively, and two large ones with the remaining genera. Within the Doradidae, parsimony analysis recovered Wertheimeria as sister to Kalyptodoras, composing a clade sister to all remaining doradids, which include Franciscodoras and two monophyletic groups: Astrodoradinae (plus Acanthodoras and Agamyxis) and Doradinae (new arrangement). Wertheimerinae, new subfamily, is described for Kalyptodoras and Wertheimeria. Doradinae is corroborated as monophyletic and composed of four groups, one including Centrochir and Platydoras, the other with the large-size species of doradids (except Oxydoras), another with Orinocodoras, Rhinodoras, and Rhynchodoras, and another with Oxydoras plus all the fimbriate-barbel doradids. Based on the results, the species of Opsodoras are included in Hemidoras; and Tenellus, new genus, is described to include Nemadoras trimaculatus, N. -

Shakati Private Game Reserve in Malaria-Free Waterberg/Vaalwater -Only 2 Hours from Pretoria
Shakati Private Game Reserve in Malaria-free Waterberg/Vaalwater -only 2 hours from Pretoria Waterberg. There is so much to see and do…. Waterberg is the area of magnificent views, panoramic savannah and bush landscapes, spectacular mountains and cliffs, crystal clear streams and an unbelievable abundance of wild animals, trees and flowers. Game viewing in the Waterberg area is absolutely fantastic and recognised among the best in the country –hence the Waterberg is one of the preferred eco-tourism destination in South Africa. Furthermore Waterberg with its unspoilt nature has been designated as UNESCO “Savannah Biosphere Reserve” –the first in Southern Africa. And Waterberg is MALARIA-free… Marakele National Park Shakati Private Game Reserve is hidden away on the lush banks of the Mokolo river in the deep heart of the untamed Waterberg bushveld paradise. Near Vaalwater and only 2 hours drive from Pretoria. Time spent at Shakati Game Reserve is about getting away from city life, work, traffic and stress. It is about peace and tranquillity, clean fresh air and clear skies with the brightest stars you have probably ever seen. It is about being quiet and listen to the jackal calling at night, to the paradise flycatcher singing in the morning. It is about seeing and walking with the animals, touching the fruits of the bush willow -and wonder about nature. It is about quietly sitting at the water hole watching game and taking life easy Its time to leave the city sounds, the hustle, the bustle and find some place that speaks to you who you really are inside. -

ARMBRUSTER* Department of Biological Sciences, Auburn University 331 Funchess, Auburn University, Alabama 36849, USA Abstract.—Catfi shes are a broadly distributed order of freshwater fi shes with 3,407 cur- rently valid species. In this paper, I review the different clades of catfi shes, all catfi sh fami- lies, and provide information on some of the more interesting aspects of catfi sh biology that express the great diversity that is present in the order. I also discuss the results of the widely successful All Catfi sh Species Inventory Project. Introduction proximately 10.8% of all fi shes and 5.5% of all ver- tebrates are catfi shes.

Introduction and Background This report relates to the request by Mr L. van Niekerk, a farmer on the banks of the Apies River, to Mr B. Hohls of the Institute for Water Quality Studies. He requested that the IWQS provide assistance in determining the possible cause, or contributing factors, of a fish kill in the Apies River reported on 6th October 2000. Mr J. Daffue of the Gauteng Regional Office of DWAF was informed of the fish kill and notified of the IWQS’s intention to assist with the water quality sampling.
