Commiphora steynii Swanepoel and C.  gariepensis Swanepoel, here described as new species, are known only from the Kaokoveld and Gariep Centres of Endemism respectively. Illustrations of the plants and distribution maps are provided. Diagnostic characters of C.  steynii include the pale ashy grey, non-peeling bark and the lack of wart-like projections around the large lenticels. Diagnostic characters of C. gariepensis include the stamen number which varies between four and eight, and the milky-watery latex which does not squirt when branches are damaged. When without leaves or fruit, C. gariepensis can easily be confused with several other species. Comprehensive tables with diagnostic morphological features to distinguish between the new species and closely related taxa are presented.

Introduction: The knowledge of polychaetes in the subtropical region of Africa benefited from the activity of J. Day. However, 50 years after the publication of his Monograph of the Polychaeta of southern Africa, it is necessary to reconsider the identity of the Cirratulidae due to changes in the diagnostic characters and new approaches to the taxonomy of the group to corroborate the status of cosmopolitan species in this region. Objective: We hypothesize that biodiversity of multitentacular Cirratulidae polychaetes has been significantly underestimated in southern Africa. Methods: The present work analyzes material deposited in the Iziko museum, as well as recently collected specimens, using scanning electron microscope to identify them. Results: The material corresponds to two new species belonging to the genus Protocirrineris. Protocirrineris strandloperarum sp. nov. is characterized by having the tentacular filaments between the chaetigers 5 to 10-12 and the first pair of branchiae from chaetiger 7, and P. magalhaesi sp. nov. is characterized by having tentacular filaments between chaetigers 4-8 and the first pair of branchiae from chaetigers 2 or 3. Descriptions of these species, with light and scanning electron microscope images, are given. Schematic drawings of the two new species are shown comparatively with diagnostic characters. Conclusions: The use of new techniques enables discovery of new taxonomic characters and two new species of the genus. The diversity of Cirratulidae polychaetes is underestimated also in the subtropical and tropical regions of Africa.

Two new species of Myrcia s.l. from the Atlantic Forest of southeastern Brazil are here described and illustrated. Myrcia longisepala and M. rogersiana share morphological features which place them in the Gomidesia clade. The species are recorded for lowland and submontane forests in the Atlantic Forest. Myrcia longisepala is morphologically related to M. congestiflora, but differs by its smaller leaves, fewer secondary leaf veins, smaller petioles and fruits. Myrcia rogersiana is morphologically related to M. springiana, but differs by its reduced inflorescence main axis and flowers clustered at the apex of the inflorescence. Distribution maps and conservation assessments based on IUCN criteria are also given.

Two new mosquito species (Diptera: Culicidae), Culex (Melanoconion) phyllados n. sp. and Culex (Melanoconion) brachiatus n. sp. from the state of Amazonas, Brazil, are here validated and described based on morphological features of the male genitalia. Both species are morphologically more similar to both Culex coppenamensis Bonne-Wepster & Bonne and Culex alinkios Sallum & Hutchings than to any other species of the Bastagarius Subgroup of the subgenus Melanoconion. Diagnostic characters for the identification of the adult male of both species are provided.

Sisyranthus species are cryptic in both their habit and small size of their flowers making them difficult to find in the wild. The genus was last revised in Flora Capensis (1908) and since then, two new species have been described. Currently it comprises 13 recognised species endemic to southern Africa. Many of these are range-restricted and poorly known. In this contribution the genus is further expanded by describing two novel species. Full descriptions, assessment of conservation status, distribution maps and line drawings of the new taxa are presented.

In this paper we re-evaluate Cyanallagma Kennedy 1920, which currently includes 15 species, and we address another five species that share diagnostic characters with some of them but are currently placed within Leptagrion Selys 1876, Mesamphiagrion Kennedy 1920, and Telagrion Selys 1876. A new genus, Oreiallagma, is described to include five species originally placed in Acanthagrion Selys 1876, Cyanallagma, and Telagrion. These species are O. thelkterion (De Marmels 1997) (type species), O. acutum (Ris 1918), O. oreas (Ris 1918), O. prothoracicum (Kimmins 1945), and O. quadricolor (Ris 1918). The last stadium larva of O. quadricolor is described. The remaining species currently includedin Cyanallagma are allocated to two separate genera: Cyanallagma sensu stricto and Mesamphiagrion. Cyanallagma sensu stricto comprises southern South American species including the type species, Cyanallagma interruptum (Selys 1876). Mesamphiagrion Kennedy 1920 includes a cluster of species from northwestern South America that are considered congeneric with the type species Mesamphiagrion occultum (Ris 1918). Two new species from Ecuador, M. dunklei and M. ecuatoriale, are described and Argia hebdomatica Navás 1934 is found to be a junior synonym of M. ovigerum (Calvert 1909). Synonymic lists, diagnoses, illustrations, keys, and distribution maps for the three genera are provided.

The South American genus Panca Evans, 1955 and its respective species are revised. Previous to this study, the genus included solely its type species, Lerodea subpunctuli Hayward, 1934, until Panca moseri Dolibaina, Carneiro & O. Mielke, 2017 was described recently. However, as a result of a broader morphological study including closely related genera, we here propose that Panca assembles 12 species, most of which inhabit open environments such as the Cerrado biome and the natural grasslands of the Atlantic Forest biome. Eight species formerly included among other genera of Moncina are here combined with Panca: Panca satyr (Evans, 1955) comb. nov., Panca tobiasi (Mielke, 1992) comb. nov., Panca trogon (Evans, 1955) comb. nov., Panca steinhauseri (Dolibaina & A. Warren, 2015) comb. nov., Panca acroleuca (Plötz, 1884) comb. nov., and Panca mirnae (O. Mielke, Dolibaina, Carneiro & A. Warren, 2015) comb. nov. (all formerly in Artines Godman, 1901), Panca paulo (Bell, 1932) comb. nov. (formerly in Eutocus Godman, 1901), and Panca mictra (Evans, 1955) comb. nov. (formerly in Vidius Evans, 1955). Additionally, two new species are described from Brazil: Panca puri Medeiros, O. Mielke & Casagrande sp. nov. (from Pará, Pernambuco, Minas Gerais, Rio de Janeiro and Paraná) and Panca xavante Medeiros, O. Mielke & Dolibaina sp. nov. (from Mato Grosso, Goiás, Distrito Federal and Minas Gerais). A neotype for Apaustus acroleuca Plötz, 1884 is designated. Illustrations of the male and female genitalia and distribution maps are presented for all the species of Panca and an identification key is provided for both sexes.

The genus chiton Loricella is revised. It comprises nine species. Two of these species, L. neoguinensis n. sp. and L. solomonensis n. sp., are described as new. Based on the analysis of morphological features studied using a scanning electron microscope, a revised diagnosis of the genus is provided. The characters diagnostic for this that distinguish it from the related genus Squamophora are as follows: a tubular hollow inside the dorsal scales, bristles on the dorsal side of the girdle, a wide ventral mouth region, a narrow mantle fold covered with simple longitudinally ribbed scales, smooth ventral scales, pits arranged in longitudinal rows in the central area of the tegmentum, and a bicuspid head of the major lateral teeth of the radula.

This publication reviews the Labidostomis species from Southeastern Europe similar to L. longimana. Two new species, L. daccordii sp. nov. (Central Greece) and L. leonardii (Greece: Kos Island, Turkey), are described. The type specimens of L. balcanica Tomov, 1987 (Croatia), L. graeca Tomov, 1990 and L. tymphristica Tomov, 1990 (both from Greece) were studied, all three species are confirmed as valid and their diagnostic characters are described. The aedeagus sclerites are introduced as useful character to separate Labidostomis species.
