Five new species of Epitola s.l. (Lycaenidae: Poritiinae) are described in the genera Stempfferia Jackson, 1962 and Cephetola Libert, 1999. Stempfferia salonga sp. n. was found in the ‘Cuvette Centrale’ of the Democratic Republic of Congo and a single specimen was identified also from southern Cameroon. The similar S. buea sp. n. is known only from the unique holotype collected at the foothills of Mount Cameroon, while S. michelliberti sp. n. is distributed in lowland rainforest between southeast Ivory Coast and Guinea. The new species of Cephetola were found only in Liberia. Cephetola praecox sp. n. is known from a single upland forest locality in the Putu Range, whereas C. wologizi sp. n. was collected also in upland forest in the Wologizi Mountains.

Three New Species

Three new species of Rubiaceae from Central Africa are described and illustrated. Chassalia lutescens O.Lachenaud & D.J.Harris (widespread from Cameroon to Democratic Republic of Congo) is recognised inter alia by the T-shaped ventral furrow of the seeds and the orange-yellow discoloration of inflorescences in herbarium specimens. Psychotria nodiflora O.Lachenaud & D.J.Harris (Central African Republic, Congo-Brazzaville and Democratic Republic of Congo), belonging to Psychotria subgen. Psychotria sect. Involucratae, is unique among African species of the genus in having paired axillary inflorescences. Psychotria pteropus O.Lachenaud & D.J.Harris (Central African Republic and Democratic Republic of Congo) belongs to Psychotria subgen. Tetramerae; it is closely related to P. leptophylla Hiern but differs in its narrow corolla tube and globose to ellipsoid fruits.

A new Alestopetersius is described from the Kwilu River in the Kasai basin of the Democratic Republic of Congo. Alesto-petersius conspectus, new species, is readily distinguished from all congeners based on attributes of squamation and col-oration. It is distinguished from “Duboisialestes” tumbensis by tooth morphology and in the possession of a distinctivecaudal-fin pigmentation patterning consisting of a median black band extending to the caudal-fin margin and flanked bydense black bands in both upper and lower fin lobes. “Duboisialestes” bifasciatus, which shares similar caudal-fin pig-mentation patterning, is distinguished from A. conspectus by the absence of a broad mid-lateral band on the body, and bytooth morphology. Results from an analysis of the relationships and generic composition of the Alestidae provide supportfor the monophyly for Alestopetersius inclusive of the members of the genus Duboisialestes, which are placed into syn-onomy with the former.Une nouvelle espèce de Alestopetersius est décrite de la rivière Kwilu dans le bassin du Kasai de la RépubliqueDemocratique du Congo. Alestopetersius conspectus, nouvelle espèce, se distingue très facilement de tout ses congénèressur les attributs de la squamation et coloration. Cette espèce est distinguée de “Duboisialestes” tumbensis par la morphol-ogie des dents et par la posséssion d'un type de pigmentation de la nageoire caudale composée d’une bande noire médianes'étendant de la marge de la caudale et flanquée de denses bandes noires dans les deux lobes supérieur et inférieur de lanageoire. “Duboisialestes” bifasciatus qui partage le même type de pigmentation de la nageoire caudale, se distingue deA. conspectus par l'absence d'une large bande mi-latérale sur le corps, et par la morphologie des dents. Les résultats d'uneanalyse des relations et de la composition générique du Alestidae fournissent un soutien pour la monophylie des Alestopetersius incluant les membres du genre Duboisialestes, qui sont placés en synonymie avec le genre précèdent.

Tropical Lowland Rainforest

The genus Haumania (Marantaceae) consists of three described species of perennial climbers endemic to the tropical lowland rainforest in Central Africa. To unravel their phylogenetic relationship to each other, we used variation among DNA sequences of two nuclear ribosomal (nr) and four plastid (p) markers in five to seven accessions per species sampled across their respective distribution range. Maximum parsimony and Bayesian analyses were applied. All datasets and analyses corroborated the monophyly of the genus. Within the genus, individuals of the species H. danckelmaniana and H. leonardiana were each monophyletic. Individuals of H. liebrechtsiana, however, were paraphyletic. They clustered into two distinct geographic clades (Gabon and Democratic Republic of Congo), with the Gabonese clade being most closely related to the individuals of H. danckelmaniana. The latter might be due to introgression in areas of distributional overlap between these two species, as shown in earlier phylogeographic studies. A recent hybridisation event between H. danckelmaniana and H. liebrechtsiana is documented here in a single individual by incongruence in the nr and p dataset. Overall, the study provides support for H. leonardiana being sister to all other species of this genus. To confirm the absence of hybridisation in H. leonardiana further sampling is proposed in the respective areas of distributional overlap with its sister species.

Constitutional Factor

Constitutions around Africa have been repeatedly tested on the issue of presidential term limits. We explore the four most recent cases of African presidents facing the end of their constitutionally mandated limit, all of which developed in Central Africa. Burundi, Rwanda, the Republic of Congo, and the Democratic Republic of Congo all adopted constitutions limiting presidential tenure to two terms; yet, in 2015, when these limits were approaching, none of the sitting presidents simply stood down. Our analysis focuses on the constitutional provisions meant to protect the two-term limit, the strategies employed by each of the four presidents, and the difficulty they faced in pursuing extended tenure. We find that constitutional provisions do constrain, but not always to the expected degree. Our analysis adds a consideration of a foundational constitutional factor to the growing literature on term limits in Africa, with implications for other regions of newly developing democracies.

Angraecoid Orchids

A recent large phylogenetic tree for the angraecoid orchids has shown that the Afrotropical genus Diaphananthe is polyphyletic with a small group of four species sister to Aerangis and Eurychone. These species have diagnostic morphological features different from any other angraecoids, notably an erose to fringed surface of the stipes and a calceiform viscidium. Diaphananthe quintasii, which has been regarded as conspecific with D. rohrii, is reinstated as a valid species and lectotypified, and Diaphananthe alfredii and Rhipidoglossum magnicalcar are put in synonymy under D. quintasii. To accommodate this group of species, along with three new taxa from West and Central Africa, a new genus named Kylicanthe is here described. Four new combinations are thus proposed, and K. bueae is chosen as the type species of the new genus and neotypified. Additionally, K. arcuata, K. cornuata, and K. perezverae are described as new species. An identification key for Kylicanthe and allied genera is presented, as well as one for the seven species in the genus. Notes on ecology and distribution in addition to a preliminary assessment of conservation status following the IUCN Red List are also provided.

The afrotropical species of the subgenus Microserrullula netolitzky, 1921, of the genus Odontium LeConte, 1848 are here revised. We redescribe the three-known species, Odontium aegyptiacum (Dejean, 1831), O. icterodes (Alluaud, 1933) and O. pogonopsis (Alluaud, 1933), and describe four new species: Odontium australe n. sp. (Kenya, Mozambique, Madagascar, South africa); Odontium basilewskyi n. sp. (Democratic Republic of Congo); Odontium okavangum n. sp. (angola, namibia, Zambia); Odontium clarkei n. sp. (Ethiopia). A key for the identification of the african species of the subgenus Microserrullula is presented.
