AbstractSix new species of foliicolous lichenized fungi are described as new to science from lowland rainforest in the Congo Basin: Bapalmuia serusiauxiana Van den Broeck, Lücking & Ertz (Pilocarpaceae) characterized by (7–)15(–19)-septate ascospores of (40–)50–65(–72)×1·5–2·5 μm, Microtheliopsis ramazaniana Van den Broeck, Lücking & Ertz (Microtheliopsidaceae) characterized by 1-septate ascospores of 13–16×3–5 μm, Phylloblastiaverheyeniana Van den Broeck, Lücking & Ertz (Verrucariaceae) characterized by 3-septate ascospores of 13–15(–17)×3·0–4·5 μm, Porina duduana Van den Broeck, Lücking & Ertz (Porinaceae) characterized by 3-septate ascospores of 11·0–14·5×2·5–3·0 μm, perithecia 130–150(–170) μm diam. and a photobiont with angular-rounded and irregularly arranged cells, Porina gryseelsiana Van den Broeck, Lücking & Ertz (Porinaceae) characterized by orange-brown perithecia and 7–9(–12)-septate ascospores of 29–46×5·0–7·5 μm, Porina weghiana Van den Broeck, Lücking & Ertz (Porinaceae) characterized by the presence of disc-shaped isidia, yellow perithecia without apical appendages and (7–)9-septate ascospores of 33–50×5·0–6·5 μm. In addition, 53 species new for the Democratic Republic of the Congo are listed, including five species new for tropical Africa and six new for the Palaeotropics, thus raising the number of species known from the Democratic Republic of the Congo from 150 to 209. Keys are presented to all known species of Microtheliopsis and to species of Porina with disc-shaped isidia.

Eunotia rudis sp. nov. is described from material collected in acid rivers in an almost pristine tropical rain forest in the Congo Basin in Central Africa. The benthic diatom community was dominated by other Eunotia spp. and small naviculoid taxa. The morphological features of the new species are described and documented based on light and scanning electron microscopy investigations. Eunotia rudis sp. nov. can be distinguished from other taxa within the genus Eunotia by its typical slightly asymmetric valve shape with four dorsal undulations and the rough surface of the thick silica wall. In contrast to other Eunotia species, the number of dorsal undulations was constant in all observed populations. Differences between the new species and the related Eunotia garucisa and E. garucisa var. polydentula are discussed.

The genus Planochelas Lyle & Haddad, 2009 is endemic to the Afrotropical region. Members of the genus are very small, arboreal sac spiders. They are mainly collected by canopy fogging in tropical forest and savanna. In this study, four new species of Planochelas are described: P.brevissp. nov., P.jocqueisp. nov. (Democratic Republic of the Congo) and P.haddadisp. nov., P.neethlingisp. nov. (South Africa). An updated key to the genus is provided, and the new species are illustrated by photographs and drawings. A distribution map for the genus is provided. This paper increases the number of species in the genus to seven.

New taxa and synonymies in the group of Liptena opaca (Kirby, 1890) (Lepidoptera, Lycaenidae, Poritiinae). A lectotype of Liptena opaca (Kirby, 1890) is designated, and the status of three of its subspecies are revised: ugandana Stempffer, Bennett & May, 1974, is raised to specific rank, centralis Stempffer, Bennett & May, 1974, is synonymized with L. opaca gabunica, and sankuru Stempffer, Bennett & May, 1974, becomes a subspecies of L. albomacula Hawker-Smith, 1933. Liptena ouesso Stempffer, Bennett & May, 1974, is synonymized with L. immaculata Grünberg, 1910. Six new species are described, four from Cameroon (L. arnouxi n. sp., L. laguerrei n. sp., L. mariae n. sp. and L. perconfusa n. sp.), one from eastern Nigeria (L. brophyi n. sp.), and one species (L. restricta n. sp.) as well as a new subspecies (L. immaculata orientis n. ssp.) from north-eastern Democratic Republic of the Congo.

Here we publish a new species of forest tree of the genus Drypetes Vahl (Putranjivaceae), D. umbricola D. J. Harris & Quintanar, which has a wide distribution in Central Africa (Cameroon, Central African Republic, Democratic Republic of the Congo, Gabon, and Republic of the Congo). It is known from 70 herbarium collections and additional sterile plot vouchers. A differential diagnosis, detailed morphological description, photographs, an illustration, and information about its habitat, distribution, and conservation status are provided.

The present paper contains descriptions of four new species of the genus Tumicla Wallengren, 1863: T. elephantina sp. nov. (South Mozambique), T. mbeghai sp. nov. (NE Tanzania), T. admiranda sp. nov. (SE Democratic Republic of the Congo) and T. smithi sp. nov. (Central Zambia). The male paratype specimen of T. doa Kühne 2007 is proved to be not conspecific with the holotype female but belongs to an undescribed species described here as T. mbeghai sp. nov. rendering Tumicla doa to be known by the female holotype only. Adults, male and female genitalia of the new and related species are illustrated.
