Description of aNew N eolebias (Characiformes; Distichodontidae) from the Upper Zambezi Drainage of Zambia

چکیده
A new distichodontid fish from small streams on the fringes of the Upper Zambezi River floodplain, Zambia, is described. Individuals of the new species, Neolebias lozii n. sp., are small (maximum 18.0 mm SL) and distinguished from all other members of the genus by a series of tall, black vertical bars along the flanks, short caudal peduncle, and broadly rounded, caudal-fin lobes. Neolebias lozii appears to be most closely related to Neolebias (=Dundocharax) bidentatus (Poll, 1967) from the Chicapa River drainage (Zaire basin) of northern Angola. In addition to its unique pigmentation pattern, Neolebias lozii differs from N. bidentatus in having a taller body, a shorter blunter snout, a shorter postorbital head length, shorter predorsal and preanal lengths, broader dorsal and anal fins, and broadly rounded instead of acutely angled caudal-fin lobes. The new species is the only southern African representative of the genus known to occur outside of the Zaire River system.

The effect of seasonal variation on anthrax epidemiology in the upper Zambezi floodplain of western Zambia
Anthrax has become endemic throughout the upper Zambezi floodplain located in the Western Province of Zambia over the recent years. To date, no comprehensive study has been carried out to determine whether recurrence of anthrax outbreaks may be linked to differences in precipitation and human activities. Retrospective data for the period 1999 to 2007 showed that a total of 1,216 bovine cases of...
متن کاملDNA barcoding reveals novel insights into pterygophagy and prey selection in distichodontid fishes (Characiformes: Distichodontidae)
DNA barcoding was used to investigate dietary habits and prey selection in members of the African-endemic family Distichodontidae noteworthy for displaying highly specialized ectoparasitic fin-eating behaviors (pterygophagy). Fin fragments recovered from the stomachs of representatives of three putatively pterygophagous distichodontid genera (Phago, Eugnathichthys, and Ichthyborus) were sequenc...
متن کاملEpizootic ulcerative syndrome: exotic fish disease threatens Africa's aquatic ecosystems.
In late 2006 an unusual ulcerative condition in wild fish was reported for the first time in Africa from the Chobe and upper Zambezi Rivers in Botswana and Namibia. Concern increased with subsistence fishermen reporting large numbers of ulcerated fish in their catches. In April 2007 the condition was confirmed as an outbreak of epizootic ulcerative syndrome (EUS). The causative agent, Aphan...
متن کاملFood habits of tilapiine cichlids of the Upper Zambezi River and floodplain during the descending phase of the hydrologic cycle
Habitat use and diets of five tilapiine populations of the Upper Zambezi River Basin in Zambia, south-central Africa, were examined during the 8 month descending phase of the annual hydrological cycle. All species occurred across a range of habitats, with most individuals captured from lagoons. Tilapia rendalli, a macrophyte feeder, was the only dietary specialist. Ontogenetic diet shifts were ...
