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. -

Published online at www.vertebrate-zoology.de on May 15, 2009. > Abstract Osteological structures of Callopanchax are fi rst described and illustrated. Twenty-six characters derived from comparisons of osseous structures among some aplocheiloid fi shes provided evidence supporting hypotheses of relationships among three western African genera (Callopanchax, Scriptaphyosemion and Archiaphyosemion), as proposed in recent molecular analysis. The clade comprising Callopanchax, Scriptaphyosemion and Archiaphyosemion is supported by a laterally displaced antero-proximal process of the fourth ceratobranchial. The sister group relationship between Callopanchax and Scriptaphyosemion is supported by a constriction on the posterior portion of the parasphenoid, an anterior expansion of the hyomandibula, a rectangular basihyal cartilage, an anterior pointed process on the fi rst vertebra, and a long ventrally directed hemal prezygapophysis on the preural centrum 2. Monophyly of Callopanchax is supported by a convexity on the dorsal margin of the opercle, a long interarcual cartilage, and long neural prezygapophyses on the anterior caudal vertebrae. > Key words Killifi shes, Callopanchax, Africa, Osteology, Annual fi shes.

Ibim, A. T*. and Gogo, O. O. Department of Fisheries, Faculty of Agriculture, University of Port Harcourt, Email: [email protected] Abstract A thirteen week investigation was conducted to document the ornamental fish assemblage of the upper reaches of New Calabar River, Rivers State. Four sample stations along the river’s course were selected. Landed fish species were collected from local fishers. Fish composition and abundance was estimated by standard methods. Results of composition revealed forty one (41) species belonging to thirty five (35) genera, in twenty five (25) families. Family composition revealed among the twenty five (25) ornamental families, the Cichlidae was most dominant with nine (9) species from five (5) genera. Species composition revealed Malapterurus electricus (Malapterurudae) as most dominant species. Species richness was highest at Station D (3.95), slightly lower in Stations B (2.91) and C (2.60), and least in Station A (1.84). Family relative abundance revealed Cichlidae (20.16%) as the most abundant family, followed by Malapterurudae (9.91%), Alestidae (8.81%), and few others. However, several families recorded low abundance, with Mastacemblidae the least (0.04%). Species abundance also, revealed Malapterurus electricus as most abundant (9.99%), followed by Erpetocheithys calabaricus (7.78%), Brycinus longipinnis (7.35%), before Tilapia zilli (7.22%), and Aethiomastacemblus nigromarginatus the least abundant (0.02%). -

Occasional Papers of the Museum of Zoology University of Michigan
February, 2006 OCCASIONAL PAPERS OF THE MUSEUM OF ZOOLOGY UNIVERSITY OF MICHIGAN CHILOGLANIS PRODUCTUS, A NEW SPECIES OF SUCKERMOUTH CATFISH (SILURIFORMES:MOCHOKIDAE) FROM ZAMBIA By Heok Hee Ngl and Reeve M. Bailey1 ABSTRACT.- Chiloglaizis productus, new species, is described from the Lunzua River, which drains into the southern tip of Lake Tanganyika in Zambia. It is easily distinguished from congeners in having a color pattern consisting of a pale midlateral stripe on a purplish gray body and without any other distinct pale patches or bands, and by the nature of its sexual dimorphism in caudal fin shape: males have a produced caudal fin (vs. diamond shaped, forked or trilobate in males of otlicr sexually dimorphic congeners). Kcy words: Chiloglaninae, Lunzua River, Lake Tanganyika INTRODUCTION Suckermouth catfishes of the genus Chiloglanis Peters, 1868 are endemic to Africa and are easily recognized by a sucker or oral disc formed by the enlarged upper and lower lips and a naked body. A total of 45 nominal species of Chiloglanis have been recognized (Seegers, 1996). During an ichthyological survey in Zambia, the second author obtained material from the Lunzua River, tributary to the southern tip of Lake Tanganyika that is clearly different from described species. The description of this material as Chiloglanis productus, new species, forms the basis of this study. METHODS AND MATERIALS Measurements were made point-to-point using a dial caliper to the nearest 0.1 mm following the methods of Ng (2004) with the following addition: oral disc width is the widest transverse distance between the extremities of the oral disc. -

Ferraris, Jr.1, Paul Skelton2, and Richard P. Vari3 Copeia 2010, No. 4, 705–715 Species of the Doumea chappuisi Complex (Siluriformes, Amphiliidae) with the Descriptions of New Species from the Upper Sanaga River and Nyong River Basins Carl J. Ferraris, Jr.1, Paul Skelton2, and Richard P. Vari3 The Doumea chappuisi complex within the catfish family Amphiliidae is diagnosed on the form of the dorsolateral and ventrolateral processes of the vertebrae along the posterior portion of the body. Three species are recognized in the complex: Doumea chappuisi of the West African coastal river basins in Guinea, Guinea-Bissau, Cote d’Ivoire, and Liberia; D. reidi, new species, described herein from a portion of the upper Sanaga River in Nigeria; and D. stilicauda, new species, described herein from the Nyong River basin in Cameroon. Members of the complex are distinguished from each other on the basis of the overall body form, the caudal-peduncle length, the predorsal length, the head length, the degree of development of the pelvic fin in larger specimens, the anterior extent of the exposed vertebral processes along the ventral surface of the body, and details of the pigmentation pattern of the unbranched rays of the pectoral and pelvic fins. ATFISHES of the amphiliid genus Doumea range interesting specimen from the Nigerian portion of the upper across a major portion of Africa from Angola Sanaga River. While closely resembling other species of C through the Congo River basin and the Lower Doumea in most features, the vertebral ossifications of the Guinea region to Guinea-Bissau. -
Piranhea Trifoliata an Amazonian Plant with Therapeutic Action: a Review
Piranhea trifoliata an Amazonian Plant with Therapeutic Action: A Review Lucineide Teixeira Vieira1, Márcia Pinheiro Da Silva1, José Dobles Dias Dos Reis Júnior1 and Anderson Oliveira Souza1* 1Federal University of Amazonas, Institute of Health and Biotechnology, Coari/AM, Brazil. Review Article ABSTRACT The use of medicinal plants reflects the reality of a part of human history. The Brazilian population with limited access to public health programs led to the development and conservation of ethnobotanical knowledge-rich information regarding medicinal plants. However, popular wisdom lacks systematization so that it can correctly use it. Herein we present the Piranhea trifoliata (family Picrondendraceae), an Amazonian plant with a wide variety of molecules with biological effects. The antimalarial effect was the dominant description observed in the studies used for this review, followed by antifungal and antioxidant actions. This review provides a synopsis of the recent literature exploring the extracts from P. trifoliata that could efficiently prevent pathologies associated with cellular maintenance mechanisms during malaria or fungal infection and oxidative stress. Keywords: Amazonian extracts; Piranhea trifoliata; biological activity; medicinal plant. 1.
