Carapa wohllebenii is described as a new tree species from the Democratic Republic of Congo, Rwanda, and Burundi. Its affinities to Carapa grandiflora are discussed. It differs in a number of morphological features; the most prominent being the oblanceolate-oblong leaflets with distinctly mucronate apex and a length/width ratio of 3.2–4.7 (vs. oblong ovate leaflets with mucronulate apex and a length/width ratio of 1.9–2.7 in C. grandiflora). A molecular phylogeny of Carapa is presented that clearly indicates the distinct phylogenetic position of both species. Based on the current knowledge, the new species is given a preliminary conservation assessment of LEAST CONCERN (LC). Carapa grandiflora is here for the first time recorded from the Democratic Republic of Congo.

AbstractMost of the current knowledge about African tephritids originates from studies performed in agricultural areas, while information about their distribution in pristine or moderately disturbed environments is extremely scarce. This study aims at (i) describing levels of spatial variability of frugivorous tephritids in tropical forests and small rural villages of the Congo River basin and (ii) verifying if human-mediated activities, such as small-scale agriculture and trade, can affect their distribution patterns. Four locations were sampled along a 250 km stretch of the Congo River. At each location, pristine and disturbed habitats (i.e. tropical forests and small rural villages, respectively) were sampled, with three replicate sites in each combination of habitat and location. Sampling with modified McPhail traps baited with four different attractants yielded 819 tephritid specimens of 29 species from seven genera (Bactrocera, Carpophthoromyia, Ceratitis, Dacus, Celidodacus, Perilampsis, Trirhithrum). The three most abundant species sampled (Dacus bivittatus, D. punctatifrons, Bactrocera invadens) showed significant variations in abundance across locations and sites and accounted for 98.29% of the overall dissimilarity between habitats. Assemblages differed among locations and sites while they showed significant differences between pristine and disturbed habitats in two out of the four locations. This study shows that frugivorous tephritids in central Congo have remarkably patchy distributions with differences among locations and sites representing the main source of variability. Our data show that, in rural villages of central Democratic Republic of Congo, human activities, such as small-scale agriculture and local commerce, are not always sufficient to promote differences between the tephritid assemblages of villages and those of the surrounding tropical forests.

Cette revue de la littérature sur les poissons du bassin hydrographique de la rivière Ulindi à l’Est de la République Démocratique du Congo a été réalisée dans le but d’avoir une idée sur l’état des connaissances actuelles de son ichtyofaune en vue de définir les orientations pour leurs études ultérieures dans cette région non encore prospectée en profondeur et dont la plupart des rivières se trouvent actuellement menacées par des activités anthropiques. Cette étude présente une vue globale des rivières du Bassin de la rivière Ulindi avec une liste systématique non exhaustive d’environ 31 espèces de poissons appartenant à 17 genres, 9 Familles et 4 ordres, basée sur la méta-analyse des différentes études taxonomiques de l’ichtyofaune du Bassin de la Rivière Ulindi, réalisées depuis l’époque coloniale du Congo-Belge jusqu’en 2019. Les résultats de cette étude constituent une aide-mémoire pour les services publics en charge de la gestion de l’environnement dans la gestion de la biodiversité ichtyologique de cet écosystème à intérêt socio-économique considérable dans la région, d’une part et une liste de contrôle aux scientifiques pour des études ultérieures.Mots clés : Ichtyofaune, Ulindi, République Démocratique du Congo, revue de la littérature, liste de contrôle.   English Title: Fishes from the Ulindi river basin, East of the Democratic Republic of Congo: review of the literatureThis review of the literature on fish in the Ulindi river basin in the east of the Democratic Republic of Congo was carried out with the aim of gaining an idea of the state of current knowledge of its fish fauna in order to define guidelines for their further studies in this region not yet explored in depth and most of the rivers of which are currently threatened by anthropogenic activities. This study presents a global view of the rivers of the Ulindi river basin with a non-exhaustive systematic list of approximately 31 fish species belonging to 17 genera, 9 Families and 4 orders, based on the meta-analysis of the various taxonomic studies of the ichtyofauna of the Ulindi river basin, carried out since the colonial times of the Belgian Congo until 2019. The results of this study constitute a baseline for the public services in charge of environmental management in the management of the ichthyological biodiversity of this ecosystem with considerable socio-economic interest in the region, on the one hand and a checklist to scientists for further studies.Keywords: Ichtyofauna, Ulindi, Democratic Republic of Congo, literature review, checklist.

The amphisbaenian Monopeltis schoutedeni is reported for the first time from Gabon based on a single individual from the extreme southeastern part of the country. The species was formerly known only from the Republic of Congo and the Democratic Republic of Congo. It is the 4th amphisbaenian and the 123rd reptile species recorded from Gabon. An identification key to Gabon amphisbaenians is provided.

"The reader's interest in the substrates of Congolese democracy is deeply revived through the writing of Jean Bofane, the place where reality and fiction become one. The start of 2019 has been a historic moment for the DRC as it is the first time that a former president has peacefully handed over power. Outgoing President Joseph Kabila cedes power to Félix Tshisekedi while maintaining the mystery of his deep and future intentions. The new President, Felix Tshilombo Tshisekedi, operates literally like the character Tshilombo in the novel Mathematiques congolaises. Starting from this resemblance, we’ve created a political-literary analysis around the events that took place both in the book and reality. Keywords: literature, politics, democracy, conflict, Democratic Republic of Congo "
