Four species of Synodontella, including three new, are reported from three species of Synodontis (S. ocellifer, S. nigrita, and S. velifer) from north-western Côte d’Ivoire. Synodontella melanoptera Dossou & Euzet, 1993 was found on the gills of S. nigrita and S. velifer and was already known from the gills of S. melanopterus in Benin and the gills of S. obesus and S. rebeli in Cameroon. The new species are Synodontella speroadotevii n. sp. from S. nigrita (type-host), S. velifer and S. ocellifer, and Synodontella bagoueensis n. sp. and Synodontella akengboi n. sp., both from S. velifer (type-host for both), S. nigrita and S. ocellifer. The new species differ from the other species of Synodontella mainly in the morphology of their male copulatory organs (MCO): Synodontella speroadotevii has a two-part penis (one being a hollow tube and the other a flattened tube); Synodontella bagoueensis has a wide G-shaped penis with a sub-terminal opening; and Synodontella akengboi has a simple narrow J-shaped penis. Synodontella speroadotevii differs from Synodontella bagoueensis and Synodontella akengboi in the shape of the dorsal transverse bar, which shows no protuberance, and also in the morphology of the MCO. Synodontella bagoueensis differs from the other two species in that it has a dorsal transverse bar that is V-shaped and a G-shaped MCO. Synodontella akengboi differs from the two other species in having a J-shaped MCO and in the size of its ventral and dorsal anchors which, contrary to the other two species, are almost similar.

Three new species of Chaetophora Kirby & Spence, 1817 (Coleoptera: Byrrhidae: Syncalptinae) are described: C. morettoi sp. nov., C. milesi sp. nov. & C. smithi sp. nov. from Côte d’Ivoire, Sierra Leone and Zambia respectively. C. medleri Johnson 1978 is redescribed with additional faunistic records. Morphological features of C. russelli (Fiori, 1978) are also discussed. A diagnostic key to currently known species of Afrotropical Chaetophora is provided.

AbstractIntroductionCôte d’Ivoire is facing a second wave of the novel coronavirus disease 2019 (COVID-19). While social distancing measures (SDM) may be an option to address this wave, SDM may be devastating, especially if they have a minimal impact on the spread of COVID-19, given the other measures in place.MethodsWe conducted a cohort study involving cases that had occurred as at June 30, 2020. We used data from the Government’s situation reports. We established three study periods, which correspond to the implementation and easing of SDM, including a 10-day delay for test results: (1) the SDM (March 11 - May 24), (2) the no SDM (May 25 - June 21), and (3) the pseudo SDM (June 22 - July 10) periods. We compared the incidence rate during these periods using Poisson regression, with sex, age, and the average daily number of tests as covariates.ResultsAs at July 10, there were 12,052 cases. The incidence rate was 100% higher during period 2 compared to period 1 (incidence rate ratio = 2.05, 95% confidence interval: 1.75-2.41) and 25% lower during period 3 compared to period 2 (0.75 [0.66-0.86]).ConclusionsThe easing and subsequent reinforcement of SDM had a significant impact on the spread of COVID-19 in Côte d’Ivoire. The other mitigation measures either did not compensate for the easing of the SDM during the no SDM period or were not fully effective throughout the study periods; they should be strengthened before the SDM are reimplemented.

ABSTRACTIn the mid-1990s, Côte d'Ivoire witnessed the rise of the ideology of ivoirité, a conception of citizenship based on autochthonous origins. Ivoirité was elaborated by a group of Ivorian intellectuals in the context of the political struggle opposing Henry Konan Bedié to Alassane Ouattara in the succession to the late President Houphouët-Boigny. Through the tactical use of the rhetoric of ivoirité, Ouattara was depicted by his adversaries as a ‘Burkinabé’ trying to rule the country. Going beyond this tactical aspect, the article addresses the ideological relations linking ivoirité to the ‘project of an Ivorian liberal society’ explicitly constructed by the same intellectuals. These relations contributed to the emergence, in the Ivorian public space, of a discourse establishing self-evident, hegemonic connections between notions like autochthony, modernity and nationality, on the one hand, and biopolitical concepts like population, immigration, security and resources on the other. The article uses two complementary perspectives to frame this emergent discourse. One focuses on the historical continuity of the political-economic strategies and population policies implemented by colonial governments and post-colonial elites. The other uses Giorgio Agamben's critical enquiry into citizenship and nationality to bring to light the implication of the ivoirité intellectuals in the construction of a national bios, and thus in the singling out of a paradigmatic form of bare life.

In the border town of Niablé, smuggling is omnipresent. The operation of this activity is based on the one hand, on social cultural relationship between neigh boring populations, and on the other hand on monetary disparities between Ghana and Côte d’Ivoire. Without denying the truth fullness of such an activity, smugglers, organized in a highly hierarchical system operate according to a strict behavioral code where one’s given word and mutual confidence are the sole modus operandi. It permits them to bring goods of diverse natures (oil products, food, pharmaceuticals, second-hand clothes drinks, etc.) in Niablé. Thus, this activity seems to be a real opportunity for these smugglers, longing for the improvement of their welfare. Besides, the smuggling allows its actors to contribute to the town’s blossoming. Such a perception of smuggling gives an idea of the animation going on in this border town. In a word, though we want it or not smuggling participates in the socio-spatial change of the town even if sometimes, it stands as an obstacle to its development. Through this contribution, we are willing to show the operation of smuggling and its influence on the town of Niablé.
