WEST CENTRAL AFRICAN PEOPLES: SURVEY OF RADIOCARBON DATES OVER THE PAST 5000 YEARS

Richard Oslisly• Ilham Bentaleb• Charly Favier• Michel Fontugne• Jean François Gillet•Julie Morin-Rivat

Résumé :

Tracing human history in west central Africa suffers from a scarcity of historical data and archaeological remains. In order to provide new insight into this problem, we reviewed 733 radiocarbon dates of archaeological sites from the end of the Late Stone Age, Neolithic Stage, and Early and Late Iron Age in Cameroon, Gabon, Central African Republic, Equatorial Guinea, Republic of Congo, and the western Democratic Republic of Congo. This review provides a spatiotemporal framework of human settlement in the forest biome. Beyond the well-known initial spread of Iron Age populations through central African forests from 2500 cal BP, it depicts the geographical patterns and links with the cultural evolution of the successive phases of human expansion from 5000 to 3000 cal BP and then from 3000 to 1600 cal BP, of the hinterland depopulation from 1350 to 860 cal BP, and of recolonization up to 500 cal BP.

Seasonal and altitudinal structure of drosophilid communities on Mt Oku (Cameroon volcanic line)

Stéphane R. Prigent, Philippe Le Gall, Shay Wilfred Mbundae, Michel Veuille

Résumé :

We assessed the potential of drosophilids as indicators of the response of  tropical ecosystems to climatic factors over an annual cycle in the montane forest of Mt Oku, by collecting samples at seven sites evenly spaced from 2200 m to 2800 m asl. Only 0.1% of the 11,000 specimens collected belonged to invading species or those commensal with humans, showing the weakness of anthropogenic factors. Species abundance was highly skewed. One species, Zaprionus vittiger, made up 81% of the sample, whereas 42 of the 62 morphological species found were represented by fewer than 20 individuals. Many of the most abundant species occurred over  a  narrow  period,  in  the  dry  or  in  the  rainy  season, others  also  occurred  at  intervening  periods.  These  different  patterns  of  population dynamics,  determined  a  succession  of  species  over  the  annual  cycle.  Abundant  species departed  significantly  from  each  other  in  their  distribution  over  collection  sites.  The drosophilid  populations  from  the  central  African  montane  forests  are  highly  dependent  on climatic  factors, either  directly, or indirectly through climatic effects on the bioticenvironment of  the  insects.

A new key to the suprageneric taxa in the beetle family Cetoniidae, with annotated liste of the known genera

J. Krikken

Résumé :

A revised key to the subfamilies, tribes and subtribes of the Cetoniidae (Coleoptera, Scarabaeoidae) is presented. Comments are given on the classification implied by the key, which includes several redefinitions. All the known genera (ca.510) are listed under their tribe or subtribe, the position of several being different from that in Schenkling’s catalogues (1921, 1922). References to recent synoptic literature are given. Eighteen new subtribes are proposed, the majority in the tribe Cremastocheilini. One new tribe is proposed, the Platygeniini. Attention is drawn to various new and neglected synonymies, original spellings, and other nomenclatural matters regarding family-group and genus-group names. The position of many genera is briefly discussed. Some striking features of the biogeography of the Cetoniidae are discussed, such as the high generic endemicity for the major biogeographical regions (for the Madagascan, Afrotropical and Australassian regions ca. 90% or more).

Contribution à l’étude de la biodiversité des coleoptères tenebrionidae de la République du Bénin: premier inventaire

Gérard Robiche, Philippe Le Gall et Georg Goergen

Résumé :

Un inventaire faunistique des coléoptères Tenebrionidae a été conduit en République du Bénin Durant plusieurs années. Cette famille était restée jusqu’ici relativement peu étudiée pour la zone géographique considérée. Les récoltes effectuées dans diverses localités représentatives des zones phytogéographiques ont permis de recenser, à ce jour, 197 espèces, dont 5 nouvelles et d’apporter quelques renseignements biologiques et écologiques sur certaines d’entre-elles. Près de la moitié des espèces répertoriées sont illustrées. Les espèces Argobrachium barrei sp. n., Oncosoma girardi sp. n. et Strongylium beniniensis sp. n. sont nouvellement décrites.

A neglected trichiine beetle from Costa Rica (Coleoptera: Cetoniidae)

J. Krikken

Résumé :

Giesbertiolus linnaei spec.nov. is described after a female from Costa Rica, in order to prevent this unusual beetle, collected as long ago as 1895, from falling into oblivion. It is compared with the two known Giesbertiolus species and with other Mesoamerican Trichiini. The ignorance as to the precise relationships of the three species included is briefly discussed.

Phylogeography and population genetics of the maize stalk borer Busseola fusca (Lepidoptera, Noctuidae) in sub-Saharan Africa

Sézonlin et al

Résumé :

The population genetics and phylogeography of African phytophagous insects have received little attention. Some, such as the maize stalk borer Busseola fusca, display significant geographic differences in ecological preferences that may be congruent with patterns of molecular variation. To test this, we collected 307 individuals of this species from maize and cultivated sorghum at 52 localities in West, Central and East Africa during the growing season. For all collected individuals, we sequenced a fragment of the mitochondrial cytochrome b. We tested hypotheses concerning the history and demographic structure of this species. Phylogenetic analyses and nested clade phylogeographic analyses (NCPA) separated the populations into three mitochondrial clades, one from West Africa, and two — Kenya I and Kenya II — from East and Central Africa. The similar nucleotide divergence between clades and nucleotide diversity within clades suggest that they became isolated at about the same time in three different refuges in sub-Saharan Africa and have similar demographic histories. The results of mismatch distribution analyses were consistent with the demographic expansion of these clades. Analysis of molecular variance (AMOVA) indicated a high level of geographic differentiation at different hierarchical levels. NCPA suggested that the observed distribution of haplotypes at several hierarchical levels within the three major clades is best accounted for by restricted gene flow with isolation by distance. The domestication of sorghum and the introduction of maize in Africa had no visible effect on the geographic patterns observed in the B. fuscamitochondrial genome.
