The Congo endemic genus Congopanchax is distinguished from all other Procato-podidae by the presence of the following exclusive character states: presence of ventral cleft in the anguloarticular, absence of premaxilla posterior margin indentation , autopalatine anterior margin concave, parhypural not contacting or slightly overlapping the hypural p...

Se describen para la parte continental de Guinea Ecuatorial dos nuevas especies de Mesoaphyosemion y una nueva especie del grupo de especies ‘Aphyosemion’ herzogi. También, se presentan los resultados de los análisis de DNAmt de casi todos los fenotipos conocidos del género Mesoaphyosemion y del grupo de especies ‘Aphyosemion’ herzogi. Ambas nuevas...

Using all data sources available, we collected 2,189 nominal scientific names that have been applied to the fishes from Gabon. Data from the literature and online database indicate that 1,062 valid species of fishes live in Gabonese waters, with 288 of these strictly restricted to freshwaters, 592 strictly restricted to marine environments and 182...

Forty years after the last Plataplochilus description was published, a new species, P. eliasi, is described from streams in the upper reaches of the Bondo River tributary (Noumbi Basin) in the Mayumbe Mountains of the Republic of the Congo. The new species is distinguished from all congeners by the males’ colouration pattern, which consists of a cr...

Available ecological information, an extensive distributional range, conflicting osteological data, and a proposed early Miocene origin provide the impetus for the present study which investigates genetic structuring, biogeographic, and phylogenetic relationships within the Aplocheilichthys spilauchen lineage. Through the analysis of the mitochondr...

Two new species of the lampeye genus Hylopanchax are described from the Ivindo River basin in the Ogowe River drainage. Hylopanchax multisquamatus, new species, and Hylopanchax thysi, new species, differ from congeners by the presence of a hyaline urogenital male papilla with small black spots and a dark‐brown reticulate pattern on the flanks of bo...

A new procatopodid, assigned to the genus Poropanchax, is described from a wetland habitat located adjacent to the Inga Falls in Lower Congo. Poropanchax pepo, new species, is distinguished from all congeners by a combination of characters including a higher D/A ratio, rounded anal and dorsal fins, a humeral blotch in males, and the absence of a sh...

Three new 'Aphyosemion' species are described from the upper Louessé River in the Massif du Chaillu, Republic of the Congo, based on a combination of DNA, habitat preference, male colour pattern, and morphological data. 'Aphyosemion' cyanoflavum, new species, is a member of the 'A'. ogoense group. It differs from its congeners by a unique colour pa...

Hypsopanchax stiassnyae, new species, is described from recent collections in the Lulua River (Kasaï drainage). All Hypsopanchax species from the southern Congo drainage share a similar supra-orbital cephalic sensory system, that differs from the characteristic zigzag shaped system of the three northern species H. catenatus, H. platystemus, H. zebr...

In 2001 werd het landelijk Beschermingsplan Knoflookpad opgesteld. Wat is er sindsdien gedaan om de stand van de Knoflookpad te verbeteren en tot welke resultaten heeft dat geleid? Wat betekent dit voor de toekomst? Waar liggen de kansen voor de Knoflookpad? In een drietal artikelen komen achtereenvolgens aan bod: de historie van de Knoflookpad in...

A new deep-bodied Hylopanchax species is described from the northwestern Congo basin. Hylopanchax paucisquamatus, new species, was collected in the Odzala-Kokoua National Park in the Likouala River drainage of the Republic of Congo. It differs from its congeners, including the deep-bodied H. leki and H. ndeko, by a unique combination of morphologic...

Three new species of the lampeye genus Hylopanchax are described from the central Congo basin: H. leki, new species, H. ndeko, new species, and H. moke, new species. These differ considerably in body shape from the two previously de- scribed species, H. stictopleuron and H. silvestris, with two deep bodied and one small and slender species. A redef...

Epiplatys atratus, a new species of the E. multifasciatus group, is described from specimens collected from several tributaries of the middle Lulua River, a tributary of the Kasai River, south of Kananga (Democratic Republic of the Congo, Kasai Occidental Province). Epiplatys atratus is the south-eastern most representative of the genus. Large adul...

Aphyosemion pseudoelegans, new species, is described, based on collections that have been misidentified for decades as A. elegans by all authors. The new species superficially resembles A. elegans, but can be distinguished from the latter and all other species of the genus by a diagnostic combination of colour pattern characters, most prominently i...

A new species of the currently monotypic genus Fenerbahce is described from the eastern Congo Basin. It is distinguished from F. formosus from the western Congo Basin by several characters, of which the most prominent are: a more anterior origin of dorsal fin relative to anal fin, a deeper body, long extension on edges of the caudal fin, and a dist...

Aphyosemion teugelsi is described from specimens collected in a small creek in the upper Wamba River basin in the southwest of the Democratic Republic of the Congo not far from the Angolan border. This is∼400 km outside the known distribution area of the genus. It is distinguished from all other members of the genus Aphyosemion by the combination o...

Recently, Fenerbahce Özdikmen et al., 2006 was proposed as a replacement name for the nothobranchiid genus Adamas Huber, 1979, which was found preoccupied by Adamas Malaise, 1945 (Hymenoptera:Tenthredinidae; Özdikmen et al. 2006). Subsequently, Huber (2007) published another replacement name, Adamans Huber, 2007, for the same genus because he chall...

Fundulopanchax kamdemi, new species, is described from small swampy pools and rivulets of the Ndian and Akpa-Yafe River systems, Cameroon. F. kamdemi is distinguished from all other known Fundulopanchax species by a unique male coloration and from most congeners by a higher number of rays in dorsal and anal fins.
