The secretarybird, the only species of the family Sagittariidae (Falconiformes), inhabits all of sub-Saharan Africa except the rain forests. Secretarybird, its vernacular name in many languages, may be derived from the Arabic “saqr at-tair”, “falcon of the hunt”, which found its way into French during the crusades. From the same period are two drawings of a “bistarda deserti” in a codex by the Holy Roman Emperor Frederick II (1194–1250). The original sketch obviously, together with other information on birds, came from the court of Sultan al-Kâmil (1180–1238) in Cairo. Careful examination led to an interpretation as Sagittarius serpentarius. Two archaeological sources and one nineteenth century observation strengthened the idea of a former occurrence of the secretarybird in the Egyptian Nile valley. André Thevet (1502–1590), a French cleric and reliable research traveller, described and depicted in 1558 a strange bird, named “Pa” in Persian language, from what he called Madagascar. The woodcut is identified as Sagittarius serpentarius. The text reveals East Africa as the real home of this bird, associated there among others with elephants. From there raises a connection to the tales of the fabulous roc, which feeds its offspring with elephants, ending up in the vernacular name of the extinct Madagascar ostrich as elephantbird.

A revised generic synopsis of sub-Saharan Hyacinthaceae is presented, based on a molecular phylogenetic analysis of the family. Generic rank is accorded only to reciprocally monophyletic clades that can be distinguished by recognizable morphological discontinuities, thereby permitting an appropriate generic assignment of species not included in the analysis. Three subfamilies are recognized within the region. Subfamily Ornithogaloideae, characterized by flattened or angular seeds with tightly adhering testa, is considered to include the single genus Ornithogalum, which is expanded to include the genera Albuca, Dipcadi, Galtonia, Neopatersonia and Pseudogaltonia. Recognizing any of these segregates at generic level renders the genus Ornithogalum polyphyletic, while subdivision of Ornithogalum into smaller, morphologically distinguishable segregates in order to preserve the monophyly of each is not possible. Subfamily Urgineoideae, characterized by flattened or winged seeds with brittle, loosely adhering testa, comprises the two mainland African genera Bowiea and Drimia. The latter is well circumscribed by its deciduous, short-lived perianth and includes the previously recognized genera Litanthus, Rhadamanthus, Schizobasis and Tenicroa. The monotypic Madagascan Igidia is provisionally included in the subfamily as a third genus on the basis of its seeds, pending molecular confirmation of its relationships. Subfamily Hyacinthoideae resolves into three clades, distinguished as tribes Hyacintheae (strictly northern hemisphere and not treated further), Massonieae and Pseudoprospereae tribus nov. Full descriptions and a key to their identification are provided for all genera. New combinations reflecting the generic circumscriptions adopted here are made for most African and all Indian and Madagascan species.

Limited Scope

We present evidence that the traditional structure of society is an important determinant of the scope of trust today. Within Africa, individuals belonging to ethnic groups that organized society using segmentary lineages exhibit a more limited scope of trust, measured by the gap between trust in relatives and trust in non-relatives. This trust gap arises because of lower levels of trust in non-relatives and not higher levels of trust in relatives. A causal interpretation of these correlations is supported by the fact that the effects are primarily found in rural areas where these forms of organization are still prevalent.

Abstract Problem gambling among young people is now a public health challenge in sub-Saharan Africa. However, the behaviour remains understudied, particularly, among rural-dwelling young people in countries within the subregion. We aimed to estimate the 12 months prevalence of problem gambling and to describe the overall and gender differences and commonalities in personal factors and social adversities associated with problem gambling among adolescents in rural Ghana. We conducted a cross-sectional survey involving a random sample of 1101 in-school adolescents aged 10–19 years in a rural district in Eastern Ghana; we used the DSM-IV-Multiple Response-Juvenile (DSM-IV-MR-J) questionnaire to assess problem gambling during the previous 12 months. Personal lifestyle and psychosocial variables were assessed using adopted items from the 2012 WHO–Global School-based Student Health Survey. Overall, three in 10 adolescents (3 in 10 females; 4 in 10 males) in rural Ghana reported problem gambling in the previous 12 months. Female adolescents who experienced problem gambling were more likely to report family-related social adversities, while adolescent male problem gambling was associated with school-related factors and interpersonal factors outside the family context. Regardless of gender, sexual abuse victimisation was associated with three times increase in the odds of experiencing problem gambling. Relative to the prevalence of gambling among adolescents in urban contexts in other countries within sub-Saharan Africa, the estimates of problem gambling among in-school rural adolescents in Ghana are higher. Although further studies are needed to understand the nuances of the behaviour, the evidence of this study underscores the need for general and targeted health promotion, intervention and prevention efforts to mitigate the family, school, and interpersonal social adversities associated with adolescent problem gambling in rural Ghana.

Niger-Congo is the largest referential language group in Africa. The extent to which it represents a true genealogical grouping is not established, though there is a large core set of members of the family that all specialists currently accept as related. These languages spread across sub-Saharan Africa, and their most significant common feature from a comparative perspective is a distinctive type of noun class system. The largest subgroup of Niger-Congo is Benue-Congo, which includes the Bantu languages that dominate the southern part of the continent. From a typological perspective, Niger-Congo languages are quite varied, especially with respect to their degree of morphological elaboration. This is also true of Benue-Congo, with some of its languages having an isolating morphological character and others showing extensive agglutinating morphology. Future comparative work on the family would likely benefit from greater integration of the results of sociolinguistic investigations into models of its historical development.

Zoogeographical Region

The family Potamonautidae Bott, 1970, currently comprises 19 genera assigned to two subfamilies (Potamonautinae Bott, 1970, and Deckeniinae Hilgendorf, 1869) based on morphological and molecular studies (Cumberlidge 1999; Daniels et al. 2006a, 2015; Cumberlidge et al. 2008; Cumberlidge & Ng 2009). All members of this family are endemic to the Afrotropical zoogeographical region that includes most of continental Africa plus the continental islands of Madagascar, the granitic Seychelles, Socotra, and the southern Arabian Peninsula. Seven genera from sub-Saharan Africa are presently assigned to Potamonautinae (see Cumberlidge et al. 2008; Daniels et al. 2015): Erimetopus Rathbun, 1894, Liberonautes Bott, 1955, Louisea Cumberlidge, 1994, Potamonautes Bott, 1970, Potamonemus Cumberlidge & Clark, 1992, Sudanonautes Bott, 1955, and Platythelphusa A. Milne-Edwards, 1887. Twelve genera from West and East Africa, Seychelles, and Madagascar are assigned to Deckeniinae (see Cumberlidge et al. 2008; Meyer et al. 2014; Daniels et al. 2015): Deckenia Hilgendorf, 1869, Seychellum Ng, Števčić & Pretzmann, 1995, Globonautes Bott, 1959, Afrithelphusa Bott, 1969, Boreas Cumberlidge & Sternberg, 2002, Foza Reed & Cumberlidge, 2006a, Hydrothelphusa A.

Abstract A zoogeographical review summarized the current distribution of 28 morphologically determined horse fly species recently collected in three Western Africa countries. In Malaise trap collections, the family Tabanidae was represented by three subfamilies, Pangoniinae, Chrysopsinae and Tabaninae (tribes Philolichini, Chrysopsini, Tabanini and Haematopotini), and six genera: Philoliche Wiedemann, 1828 (1 species), Chrysops Meigen, 1803 (3 specis), Ancala Enderlein, 1922 (2 species), Euancala Enderlein, 1922 (1 species), Tabanus Linnaeus, 1758 (13 species) and Haematopota Meigen, 1803 (8 species). Information contained in the principal publication The Catalogue of the Diptera of the Afrotropical Region 1980 is complemented by newly published studies on horse flies in Sub-Saharan Africa.

Acaciella angustissima (Mill.) Brit. & Rose is a multipurpose deciduous thornless shrub or small tree that belongs to the family Fabaceae and subfamily Mimosoideae. This study aimed to explore A. angustissima, a leguminous shrub with medicinal, ecological and industrial potential. A mixed-method approach, which included consolidating quantitative and qualitative research, was utilized to put together the review with the main focus being on sub-Saharan Africa. However, case studies and literature from South Africa were also utilized. A. angustissima is a good source of phenolic compounds. It is used to relieve painful toothache, rheumatism, skin lesions, bloody diarrhea and mucoid diarrhea. It also displays a mild antimicrobial effect and has the ability to inhibit growth in malignant tumors. The study acknowledged Acaciella angustissima as an important agroforestry tree species that improve the quality of life of resource-poor farmers, reducing poverty and promoting sustainability of the natural resources base and economic growth

Normative Order

Customary law grows out of the social practices which a given jural community has come to accept as obligatory. It is a pervasive normative order, providing the regulatory framework for spheres of human activity as diverse as the family, the neighbourhood, the business of merchant banking, or international diplomacy. This article looks at the customary laws of sub-Saharan Africa. It deals with the preservation of the law in an oral tradition and how it has been influenced by certain social, economic, and political structures. This focus requires, in turn, that particular attention be paid to factors influencing the production of texts on customary law. Because information on the subject is limited, outdated, and somewhat subjective, readers must be made aware of how changes in the theories of jurisprudence and anthropology have affected ideas and preconceptions.
