Abacaecus n. gen. walterrossii n. sp., a notable blind species from Sierra Leone, is described. A. walterrossii n. sp. probably belongs to a separated phyletic lineage inside Abacetini sensu lato and is the first recorded blind African species of this tribe. It is also compared to Pterostillichus caecus Straneo, another African blind species of uncertain affinities, of which is given an integrative description enriched by illustration of a few characters.

Ebov Infection

Ebola virus (EBOV) infection is characterized by an excessive inflammatory response, a loss of lymphocytes and a general paralysis of the immune system, however pathophysiological mechanisms are not fully understood. In a cohort of 23 fatal and 21 survivors of ebola virus disease (EVD) cases admitted to the Emergency Ebola-Treatment-Center in Goderich (Freetown, Sierra Leone) during the 2014 to 2016 EBOV epidemic in Western Africa, we analyzed the pathway-focused gene expression profile of secreted proteins involved in the immune response and the levels of specific anti-EBOV IgM and IgG from the time of admission till discharge or death. We observed a dysregulated inflammatory response in fatal patients as compared to survivors, mainly consisting of the upregulation of inflammatory mediators, whose extent directly correlated with viremia levels. The upregulation persisted and intensified during the late phase of infection. Relevant differences were also found in humoral immunity, as an earlier and more robust EBOV antibody response was observed in survivor patients.

In various parts of Western Africa it appears to be the practice to subject to the ordeal by poison persons who come under suspicion of having committed heinous crimes. On the banks of the Gambia river the poison used for the purpose is the bark of a leguminous tree, theFillœa suaveolensof MM. Guillemin and Perottet. In the neighbourhood of Sierra Leone it is the bark ofErythrophleum guinëense, which some botanists have considered identical with the former species. On the Congo river, Captain Tuckey found that either this species, or an allied species of the same genus, was in constant use for the same purpose.

Time Of Year

Cartographical analysis of the distribution of recorded swarming populations of Locusta migratoria migratorioides (R. & F.) in western Africa for the first four years of the 1928–41 plague of this species has shown seasonal latitudinal displacements in each year with a nroth-to-northweastward movement of swarms during the monthe February-March to August-September, and a south-to-south-westward return during the priod October until the end of the year or January or Ferbruary of the following year.Changes in the position of the northern limit of distribution of swatms in western Africa from month during 1931 have indicated a probable relationship between its position and that of the Intertropical Front, in its seasonal displacement, the position of the surface front being inferred from that of the 10-mm. isohyet. From February to September 1931, following the northward displacement of the Intertropical Front and the northward penetration of south-westerly winds, a general northward displacement of swarms occurred. Similarly, following the southward advance of northerly winds, there was a southward displacement of swarms.There was an eastward movement in the main latitudinal displacement. This was particularly marked in 1929 and 1930. By September 1929, the infestation that in April had been restricted to parts of south-western Guinea and norther Sierra Leone had spread north-eastwards to cover the greater part of the Voltaic Republic and southern Mali; from December 1929 to January-February 1930, following the south-westward movement from late September to November 1929 which confined swarms to the countries bordering the Atlantic and the Gulf of Guinea. there was a spread eastwards along the coastal areas from south-eastern Ghana to southern and eastern Nigeria; and following the main northward movement of swarms which began in western AFrica in April 1930, there was, from May-June onwards, a pronounced eastward migration to the central and eastern parts of the continent. Each of these eastward movements occurred in areas where, at that particular time of year, the prevailing winds would be from the south-west.The deduced movements suggest that swarms of Locusta in western Africa move downwind, and that the principal seasonal changes in the distribution of swarms in that area occur in response to the latitudinal displacement of the Intertropical Front and its associated wind field.

The fauna of whip spiders (Amblypygi) in Western Africa is poorly known but probably diverse. Here, I describe the new speciesCharinuskakumsp. n.based on female morphology, and accompanied by DNA sequence data. The species is small and differs from other African species ofCharinusin the low number of pseudosegments on leg IV, female genital features, spination patterns of the pedipalp, and small body size. It was collected from wet tropical rainforest in Kakum National Park, Ghana and is only the fourth species ofCharinusto be recorded from the highly diverse Western African biodiversity hotspot. With a total body length of not even 6 mm it is also one of the smallest whip spiders in the world.

The Afrotropical planthopper genus Centromeriana Melichar, 1912 (Hemiptera, Fulgoromorpha, Dictyopharidae, Dictyopharinae, Orthopagini) is revised. Four species are included: C. jocosa (Gerstaecker, 1895) (the type species, with confirmed records from Cameroon, Equatorial Guinea and Gabon), C. lindbergae sp. nov. (described from Sierra Leone), C. rhinoceros sp. nov. (described from Togo) and C. simplex Melichar, 1912 (so far only known from Equatorial Guinea, Bioko island). Lectotypes are designated for C. jocosa and C. simplex and both species are redescribed including habitus photographs and detailed illustrations of the male and female genitalia which are published for the first time. A key for identification of the species of Centromeriana is provided. As far as known, the genus is endemic to the (Guineo-)Congolian region of western Africa.

A New Species

During a soil zoological expedition to São Tomé and Príncipe in 2010 by the California Academy of Sciences, millipedes of the genus Globanus were collected. Samples of G. marginescaber (Karsch, 1884) and G. integer (Karsch, 1884) were recovered in addition to those containing a new species. Globanus drewesisp. nov. is described and additional records, illustrations, and descriptive notes are given for the other two species. A key to all three species of the genus is provided, and a distribution map is presented. The monotypic genus Lobogonus Demange, 1971, which includes L. trilobatus Demange, 1971, from Sierra Leone, mainland western Africa, is revalidated and removed from synonymy under Globanus. Lobogonus is illustrated from a type specimen.

Eastern Whites in Western AfricaMy article on Zaburro was written in the expectation that it would stimulate discussion over the antiquity of maize in West Africa, and the matter has been taken up by Professor Portères (1959), on whose publication Mr. Willett has relied for certain inferences in his article in Africa for January 1962. Among the interesting points brought forward by Professor Portères (1959, vi) are the groups of African vernacular names which indicate that maize was introduced by foreigners, strangers, whitemen. A similar observation had been made more than a hundred years ago by Koelle (a. 1854, v), a missionary in Sierra Leone, who wrote: ‘…the names for onion, rice, maize, &c. show that in many countries [in Africa] these articles have been introduced by foreigners.…’ Who these foreigners were Koelle, with his long list of vernacular words for whiteman to choose from, leaves indeterminate. On the other hand, underlying Professor Portères's view that it was the Portuguese or the Dutch who brought maize to the Guynee coast, lies the assumption that the foreigners, the strangers, the whitemen indicated by these vernacular names were the Portuguese and the Dutch.
