In describing the following new species from West Africa, some words of explanation are needed as to the generic names used. In the first place, it is necessary to say that the writer follows Messrs. Dyar and Knab in considering that most of the genera into which Meigen's genus Anopheles has recently been split up are not genera in any accepted sense, and should sink under the old name Anopheles. Provisionally, however, Stethomyia, Chagasia, Calvertina and Bironella are considered as distinct; as none of these genera are African, this will not affect the present paper. Lieut.-Col. A. Alcock, of the London School of Tropical Medicine, has kindly allowed me to see the manuscript of a paper on the classification of Anopheles, which he is about to publish in the Annals and Magazine of Natural History, and I have been able to concur entirely with his views; he recognises only five sub-genera of Anopheles, the sub-genus Nyssorhynchus including all those species with flat scales on thorax and abdomen, i.e., the genera Nyssorhynchus, Cellia and Neocellia of Theobald's Monograph.

A New Species

The material of this study consists of three monogenetic trematodes which were collected in mid August, I960 from the urinary bladder of Rana (Ptychadena) oxyrhynchus caught in Kumba, the Cameroons (West Africa). Mr. F. R. N. Pester, F.I.S.T., of the Department of Parasitology, London School of Hygiene and Tropical Medicine kindly forwarded the material to the writer for identification.The specimens are all identical, belonging to a new species of the genus Polystoma Zeder, 1800 which is described herein as Polystoma Prudhoei sp. nov. in honour of Mr. S. Prudhoe of the Department of Zoology, the British Museum (Natural History) for his unfailing help and advice.

Forest Coverage

The state of knowledge on sylvan katydids (Tettigoniidae, Pseudophyllinae) of Guinean Forests of West Africa hotspot is discussed. Based on published data on their distribution, and the extent of the current forest coverage of the region it is possible that some of the West African species of the Pseudophyllinae may be threatened or even extinct. Five new species are described (Adapantus affluens sp. nov., A. angulatus sp. nov., A. pragerorurm sp. nov., Tomias gerriesmithae sp. nov., and Mormotus alonsae sp. nov.), and 4 species of West African Pseudophyllinae are redescribed.

Palpares longimaculatus nov. sp. is described from West Africa. This species resembles P. radiatus Rambur, 1842 and P. incommodus (Walker, 1853) from the same region and is very similar to P. kalahariensis Stitz, 1912 from South Africa. The characters differentiating these species are indicated. An identification key to the West African species of Palpares is provided and all the keyed species are illustrated.

A New Species

The separation of Thecacoris and Cyathogyne (Phyllanthaceae, formerly Euphorbiaceae) is discussed and it is concluded that they should remain united. A separation of the continental forest species (except Thecacoris viridis (Müll.Arg.) Leandri ex G.L.Webster) awaits molecular investigation. Thecacoris micrantha sp. nov. is described and illustrated. Thecacoris grandifolia (Pax & K.Hoffm.) Govaerts from Cameroon is neotypified. Thecacoris membranacea Pax and T. annobonae Pax & K.Hoffm. are lectotypified and placed in synonymy under T. stenopetala (Müll.Arg.) Müll.Arg. and T. trichogyne Müll.Arg., respectively. Thecacoris manniana (Müll.Arg.) Müll.Arg. is united with T. stenopetala under the latter name. A key to and a synopsis of the West African species is provided.

African Genus

The Anchonini known from Africa are reviewed. The monotypic genus Aethiopacorep is redescribed. The new West African genus Titilayo gen. nov. is described, with seven new species: four from São Tomé, T. perrinae sp. nov., T. saotomense sp. nov., T. barclayi sp. nov., and T. turneri sp. nov.; two from Ivory Coast, T. geiseri sp. nov. and T. garnerae sp. nov.; and one from Sierra Leone, T. takanoi sp. nov. Neither of these genera is known outside West Africa. A neotype is designated for Anchonus africanus Hustache 1932. A key to the two African genera, Aethiopacorep and Titilayo, as well as their corresponding species, is provided. This work provides the first records of Anchonini for mainland Africa; this group is still understudied in the region but shows signs of being very diverse on both the mainland and in the western African islands.

Material collected between 1984 and 1988 in Guinea and Mali and between 2003 and 2008 in the Ivory Coast substantially increased our knowledge of Labiobaetis Novikova & Kluge in West Africa. We identified eight different species using morphological characters. One species, L. ediaisp. nov., is new to science; it is described and illustrated, based on its nymphs. The status of L. boussoulius (Gillies, 1993) is discussed and the divergent morphology of L. elouardi (Gillies, 1993) is compared to other species of Labiobaetis. A key to the nymphs of all West African species is provided and the distribution of Labiobaetis species in the Afrotropical realm is discussed.

These keys and illustrations have been prepared in response to many requests. They concern only those species of Anopheles which have been recorded as occurring in West Africa south of the Sahara Desert as far as the equator. Much of the material has been derived from the recent Monograph by the late Dr. A. M. Evans on the Anophelines of the Ethiopian Region published by the British Museum in 1938. Personal acquaintance with the Anophelines of East and South Africa and examination of the specimens in the collection of the Department of Entomology of the London School of Hygiene and Tropical Medicine have assisted in the preparation of the keys.

Reef Fauna

Six sympatric species of the cone shell genus Lautoconus Monterosato, 1923 have been discovered on an isolated rock reef near the Gambia River Mouth, Gambia, West Africa. Of these, four were found to be new to science and, together, they represent a previously unknown Gambian endemic species radiation. These include: Lautoconus fernandi new species, L. gambiensis new species, L. rikae new species, and L. wolof new species. The poorly-known Gambian endemic cone, Lautoconus orri (Ninomiya and da Motta, 1982) was also found to be a component of the rock reef fauna, as was the wide-ranging L. guinaicus (Hwass, 1792) (Senegal to Ghana). The Gambian cluster of sibling species represents the farthest-south separate radiation of Lautoconus known from the West African coast.

Having devoted several weeks to the study of the magnificent collection of the remains of Ichthyopterygians preserved in the British Museum (Natural History), I purpose on this occasion to give a brief notice of some of the conclusions at which I have arrived, since a considerable interval will elapse before the publication of that part of the Museum “Catalogue of Fossil Eeptilia” in which my observations will be more fully recorded.

A new small West African Arthroleptis from the rainforest at the south-eastern tip of Mount Nimba, Liberia is described. The new species differs from all known congeners by the combination of a unique color pattern, a rounded canthal region and a completely smooth skin. The comparison of 592 base pairs of the mitochondrial 16S rRNA from the new species with Arthroleptis samples from all over West Africa, revealed genetic distances between 13.4–17.9%. From the morphologically similar A. aureoli the new species differed by 17.9%. Future research may reveal the necessity to establish a new genus for this peculiar new frog.
