The state São Tomé and Príncipe consists of two separated oceanic archipelagos situated in the Gulf of Guinea (West Central Africa). Except of a first survey on São Tomé in the 19th century, its Orthoptera fauna has never been studied systematically. Here a list of all tettigonioid species which have been recorded from the islands is presented together with information about the bioacoustics and biology of some species. Each archipelago harbours nine species, but only two species are found in both parts of the country. Two species and one subgenus are described as new: Adapantus (Adapantus) excavatus sp. nov., Brachyamytta bombomensis sp. nov., Neoadapantus subg. nov. The following nomenclatural changes had to be done: Corycoides greeffi (Krauss, 1890) becomes new synonym of Corycoides paradoxus (Bolivar, 1890), Xiphidion guineensis Redtenbacher, 1891, Xiphidion africanum Redtenbacher, 1891 and Conocephalus inequalis Uvarov, 1928 become new synonyms of Conocephalus iris Serville, 1838. The species list of Conocephalus, subgenus Conocephalus, is revised. Additionally the known tettigonioids of Annobón (Equatorial Guinea) are listed (4 species). 

In 2020 Cabo Verde (1557 sq. miles) and São Tomé and Príncipe (621 sq. miles) had a resident population of 556,857 and 210,240 respectively. Both archipelagos were uninhabited when they were settled by Portuguese colonists and African slaves in the second half of the 15th century. The coexistence of Europeans and Africans resulted in the emergence of Creole societies. Due to their differences in geographic position and climate, they developed unequally in economic terms. Santiago, the first of the Cabo Verde Islands to be settled, became a commercial hub for the slave trade from the Upper Guinea coast. São Tomé was also engaged in the slave trade, but in the 16th century established the first tropical plantation economy based on sugar and slave labor. In the 17th century, both archipelagos were affected by economic and demographic decline. Economic recovery did not occur before the mid-19th century. The British established a coal supply station for transatlantic steam shipping in São Vicente, while, enabled by the introduction of coffee and cocoa, the Portuguese reestablished the plantation economy in São Tomé and Príncipe. After the abolition of slavery in 1875 the workforce was composed of contract workers from Angola, Cabo Verde, and Mozambique. As a result, São Tomé and Príncipe became marked by immigration for almost a century. In contrast, pushed by famines and misery, a massive emigration from Cabo Verde began in the 19th century, a feature that has marked the archipelago’s society and identity until the early 21st century. The first anticolonial groups in exile appeared in the late 1950s. An armed liberation struggle in the islands was not possible; however, a group of Cabo Verdeans participated in the armed struggle in Portuguese Guinea. Most prominent among them was Amílcar Cabral (b. 1924–d. 1973). After independence in 1975 the two countries became socialist one-party regimes. In 1990 both archipelagos introduced multiparty democracies with semipresidential regimes. Creole communities also developed in the Gulf of Guinea islands of Bioko (779 square miles) and Annobón (6.5 sq. miles), which belonged to Portugal until 1778 when they became part of Spanish Guinea which subsequently, in 1968, gained independence as Equatorial Guinea. In the 16th century the uninhabited island of Annobón was settled by the Portuguese with African slaves. As a result, the island’s early-21st-century 5,300 inhabitants speak a Portuguese-based Creole, Fá d’Ambó. Bioko (Fernando Po), was the only Gulf of Guinea Island with a native population, the Bubi, and therefore the Portuguese never colonized this island. From 1827–1843 the British navy maintained an antislaving station called Port Clarence (modern Malabo) in Fernando Po. The British recruited workers from Freetown in Sierra Leone, which was the beginning of the development of the Fernandinos, a local Creole community that speaks an English-based Creole language known as Pichi, which is closely related to Krio in Sierra Leone. Currently, there are still about thirty Fernandino families, comprising some 350 people; however, Pichi is spoken by an estimated 150,000 people, since it also became Bioko’s lingua franca spoken by the Bubi majority.

The numbering systems used by Júlio Henriques when specimens were prepared for distribution as donations or for determination from the Herbarium COI (Coimbra, Portugal) are addressed, with particular emphasis on the collections made by Adolfo Moller and Francisco Quintas on São Tomé and Príncipe in the 19th century. The conflicting numbers and label data that are found on these collections have been the source of considerable confusion in determining what constitute duplicates, and in many cases the type status of such collections. An understanding of the administrative methodology and numbering system used by Henriques is critical in taxonomic studies on the flora of São Tomé and Príncipe and adjacent areas, as the early collections inevitably included large numbers of type specimens. Previous work done by Arthur Exell to address the issue is analysed and explained, and examples are presented.

Background: After the worldwide spread of the coronavirus pandemic, several experts predicted a health catastrophe in Africa. However, the expected earthquake ultimately did not occur and the statistics of the number COVID-19 cases and deaths for other continents (Europe, America, Asia) were far higher than those of Africa. This study focused on Central Africa tried to explain this low incidence of COVID-19. Methodology: A cross-sectional time series method was adopted and the data of COVID-19 cases and deaths for Angola, Cameroon, Chad, Central African Republic, Congo Brazzaville, Democratic Republic of Congo, Gabon, Equatorial Guinea and Sao Tome and Principe between March and November 2020 were extracted from the World Health Organization COVID-19 database. The evolution of COVID-19 cases and deaths for each country were plotted and the accuracy measures such as Mean Absolute Percentage Error, Median Absolute Deviation and Mean Squared Displacement were calculated. Association between the countries and the prevalence of cases, deaths and recovered was visualized through principal component analysis. Results: The results showed that the highest number of cases was observed in Cameroon (21,793) while Sao Tome and Principe scored the smallest one (962). However, based on the total population, the prevalence of COVID-19 cases was high in Sao Tome and Principe (0.436%) and Gabon (0.400%). The highest death percentages (≥2%) were observed in Chad (6.742%), RDC (2.708%) and Angola (2.592%) while the highest recovered percentages were in Gabon (99.10%), Equatorial Guinea (97.62%) and Cameroon (97.02%). Development of traditional medicines and modification of food behavior including consumption of plant extracts appear as the reasons for the highest recovered rates. The accuracy measurements showed that the trend curves were not correlated with the actual evolution of the pandemic, but the Spearman correlation test revealed that except Equatorial Guinea (r=0.042, p=0.817), the evolution of COVID-19 cases and deaths were strongly correlated. Conclusion: The overall prevalence and incidence of COVID-19 is low in the countries of the Central Africa sub-region despite the problems facing the health systems of these countries.

Equatorial Guinea is found in west central Africa. It has an area of 28,000 square kilometres (km) and is composed of a mainland, Río Muni, and small islands including Bioko where the current capital Malabo is located. The mainland Río Muni totals about 93 per cent of the nation’s land area and 75–80 per cent of its population. Río Muni is bordered by the Gulf of Guinea, Cameroon in the north, and Gabon in the south and east. The largest city in Equatorial Guinea, Bata, as well as the country’s future planned capital, Oyala, are found on the mainland. In 2016, the population amounted to 1.2 million. The currency used is the Central African franc (CFA). Office hours in the public sector are from 0800 to 1600 from Monday to Friday.

Friedrich Welwitsch (1806–1872) is best known for his botanical work in Angola in south-tropical Africa. However, he also was one of the first plant collectors on the islands of São Tomé and Príncipe, Gulf of Guinea, while en route to Angola in 1853, and again seven years later when returning to Lisbon, Portugal. The contributions of Welwitsch to the floristics of these two islands are discussed. Reference is also made to the other mid-19th century botanical collectors who were active in São Tomé and Príncipe. The typification of the names Ehretia scrobiculata, Hernandia beninensis, and Leea tinctoria, which are all based on Welwitsch specimens, is clarified. Two endemics of the Gulf of Guinea islands have names coined by Welwitsch. Their nomenclature is clarified, and the names are here second-step lectotypified. We show that authorship of the name Leea tinctoria should be attributed to Welwitsch, not to ‘Lindley ex Baker’.

This paper summarizes current knowledge about Central African pholcids. Central Africa is here defined as the area between 10°N and 7°S and between 6°E and 18°E, including mainly the Lower Guinean subregion of the Guineo-Congolian center of endemism. This includes all of Gabon, Equatorial Guinea, São Tomé and Príncipe, most of Cameroon and Congo Republic, and parts of the neighboring countries. An annotated list of the 14 genera and 79 species recorded from this area is given, together with distribution maps and an identification key to genera. Seven species are newly described: Anansus kamwai sp. nov., Leptopholcus gabonicus sp. nov., Ninetis faro sp. nov., Pholcus punu sp. nov., P. rawiriae sp. nov., Spermophora abibae sp. nov., and S. awalai sp. nov. Additional new records are given for 16 previously described species, including 17 new country records. Distribution and diversity patterns are compared with data on West and East Africa. While West Africa contains a similar set of genera it is significantly less diverse than Central Africa. East Africa is taxonomically more distinct. It has similar levels of diversity as Central Africa, but appears to be less undersampled.

Between the 16th and 19th centuries, great numbers of men and women in the Americas escaped slavery by joining communities of fugitives. In Brazil, these communities were called mocambos, at first, and they were later referred to as quilombos, both of which were African terms that designated camps in several small societies in Central West Africa. It remains unclear to researchers what terms fugitives used to name themselves. As far as is known, the Portuguese colonial administration was responsible for disseminating the terms mocambos and quilombos. Colonial authorities moved around the Portuguese Empire and frequently took up posts in Africa and Asia prior to their arrival in South America. The term quilombo originally designated both Portuguese military strategies in precolonial Africa and forms of resistance to slavery in Portuguese America. Therefore, by using the term, colonial authorities could be referring to two different entities: war and prisoner camps in Central Africa or communities of runaway slaves in Brazil. Apart from that fact, several military officials who served in Africa had previous experiences in military campaigns against Dutch attacks in the 17th century in Portuguese America as well as in expeditions to dismantle mocambos and capture indigenous slaves. In any case, the term quilombo emerges only in the colony’s historical documentation by the end of the 17th century. Before that time, runaway communities were most commonly referred to by the name mocambos. Found in documents of colonial administration of the Captaincy of Bahia, the earliest reference to mocambos in Portuguese America dates from 1757. By the late 16th century, records point to the existence of Quilombo dos Palmares in the Captaincy of Pernambuco. Colonial authorities did not consider it completely destroyed until the beginning of the 18th century. Other large quilombos emerged during the 18th century in mining areas of Goiás, Mato Grosso, and Minas Gerais. Throughout the 19th century, quilombo communities proliferated in various locations: they could be found close to mining areas, plantations, or smaller farms; in vacant lands on economic frontiers and backlands inhabited by indigenous peoples; and in border areas such as those between Brazil and the Guianas. They also became part of urban landscapes, especially in the last decades of the 19th century. However, these communities were smaller, the modest dimensions of which enabled their longevity. Defined by specific cultural, social, and economic lifestyles and worldviews, quilombo communities survived post-abolition and they exist up to today.

Cophixalus represents the most diverse genus of microhylid frogs. Within this group I show that two recently describedspecies are in fact synonyms of species described in the 19th Century. Proper recognition of one of these has been hinderedby the poor state of the syntypes and confused information presented in earlier literature. The second species was simplynot diagnosed against other members of the genus. I also describe five new species: one of these is known only from asingle specimen from far western New Guinea, two occupy the Papuan Peninsula in the east of that island, and two arerestricted to Woodlark Island off the southeastern tip of New Guinea. One of these new species had earlier been mis-iden-tified as C. pipilans, requiring me to herein provide a corrected comparison of features that distinguishes C. desticans fromC. pipilans. These taxonomic changes bring the number of Cophixalus species to 61, of which 42 inhabit New Guinea andimmediately adjacent islands. But much of this region remains poorly surveyed, and, undoubtedly, many additional spe-cies remain to be described. I provide the first dichotomous key for the Papuan members of this genus, which should facilitate description of additional species.

The following 4 species are new records for Australia: B. aspercera Mohrig, B. centidens Vilkamaa, Hippa & Mohrig (both from Papua New Guinea), B. gibbosa Vilkamaa, Hippa & Mohrig and Pseudolycoriella capillosa Vilkamaa, Hippa & Mohrig (both from New Caledonia). Euricrium australiensis sp. n. is the type species of the subgenus Austroeuricrium subgen. n. First detections of the species B. conjuncta (Skuse), B. exsequialis (Skuse), B. pernitida (Skuse) and B. pictipes (Skuse) were made after their description in the 19th century. One species was declared as a new synonym: B. centidens Vilkamaa, Hippa & Mohrig, 2012 = B. mutuata Mohrig, 2016 syn. n. Five species were excluded from the subgenus Peyerimhoffia. Four are newly combined in the genus Corynoptera, crassistylata group [C. sparsula (Shi & Huang) comb. n., C. brachypoda (Shi & Huang) comb. n., C. yunnana (Shi & Huang) comb. n., C. shennongjiana (Shi & Huang) comb. n.], one in Corynoptera s. str. [C. longiprojecta (Shi & Huang) comb. n.]. Corynoptera longiprojecta (Shi & Huang) is a junior synonym of Corynoptera diversicalcaria Mohrig, 2004 from Papua New Guinea.
