The genera Eremohaplomydas Bequaert, 1959, Haplomydas Bezzi, 1924, and Lachnocorynus Hesse, 1969 (Diptera: Mydidae: Syllegomydinae) are revised. Currently, four species are known from southern Africa, i.e., Eremohaplomydas desertorum Bequaert, 1959 from north-western Namibia, Haplomydas crassipes Bezzi, 1924 widespread in southern Africa, Lachnocorynus chobeensis Hesse, 1969 from northern Botswana, and Lachnocorynus kochi Hesse, 1969 from northern Namibia. Four new species, Eremohaplomydas gobabebensissp. nov. and Eremohaplomydas whartonisp. nov. from the central Namib desert of Namibia, Eremohaplomydas stomachorissp. nov. from the northern Namib desert in Namibia, and Lachnocorynus stenocephalussp. nov. from north-eastern Zimbabwe are described. Lachnocorynus kochi is synonymized with Lachnocorynus chobeensis. Distribution, biology, occurrence in biodiversity hotspots sensu Conservation International and seasonal imago flight activity are discussed. Descriptions/redescriptions, photographs, specimen occurrence data, and identification keys (both dichotomous and matrix-based) to species are provided and made openly accessible in data repositories to support and accelerate future studies of the included taxa. An updated identification key to the Mydidae genera of the Afrotropical Region is provided. The placement of the three genera in the subfamily taxon Syllegomydinae is discussed and several morphological features, such as an extremely reduced proboscis in some species, a unique wing venation in Eremohaplomydas gobabebensissp. nov., and the unique metathoracic coxa, are discussed.

Scrapter is a genus of colletid bees with a primary distribution centered in Southern Africa. The genus currently comprises 68 recognized species, which are divided into nine species groups, ranging from one to 29 included species. The Scrapter heterodoxus group is presently considered to be the only monotypic group, because of synonymization of Scrapter heterodoxus with Scrapter peringueyi in a previous revision of the genus. A comparative examination of these two species using both morphological assessment and molecular sequence data from the COI barcode region supported the recognition of S. peringueyi as a valid species, which we accordingly resurrect as the second species of the Scrapter heterodoxus species group. We provide high resolution images of the type specimens for both species and updated diagnoses to enable their separation from all other species of Scrapter.

The endemic, monotypic Afrotropical genus Spathioplites Fischer, 1962 is rediscovered based on new specimens collected in South Africa and Senegal. Spathioplites phreneticus Fischer, 1962 was previously known from the holotype (male) and 12 paratypes (11 males and a female) collected in Chad in 1959. As part of an ongoing long-term insect inventory survey program in Africa new specimens were recently collected in Tswalu Kalahari Game Reserve in South Africa, extending the distribution range southwards by 4900 km. An additional historical specimen from Senegal was discovered in the collections of the Natural History Museum in Paris, extending the range westwards by 4000 km. Possible reasons for the disjunct distribution exhibited by current locality records for this species are discussed. The holotype male and a paratype female, as well as one of the two newly collected South African females were imaged. These photographs, as well as genus and species re-descriptions, are provided. An identification key to the Old World genera in the doryctine tribe Spathiini s. str. is also presented. All images and interactive identification keys are available on

A new genus of Baetidae, Megalabiopsgen. nov., and a new species, M. madagasikarasp. nov., are described from Madagascar based on nymphs. The new genus is characterized by having a strongly enlarged mentum; pedicelli with many long, stout, pointed setae; a brush of dense, short setae between prostheca and mola of both mandibles; an apically pointed maxillary palp with a stout seta at the tip; and a labium with many long, simple setae ventrally on glossae. The patellotibial suture is absent on the fore tibia and present on middle and hind tibiae. The claw is strongly elongated with two rows of denticles. The imago remains unknown and the relationships with other African genera of Baetidae are tentative. Despite being easily identifiable, only two nymphs were found in two highly sampled localities in Madagascar.

Material collected in 1974 during the Austrian Hydrobiological Mission of F. Starmühlner to the Comoros and during recent years by one of the authors (NM) in the course of an ongoing freshwater monitoring program in Mayotte is the basis of this first larger study of the mayfly family Baetidae in the Comoros Archipelago (Comoros, Mayotte). We identified eight different species using morphological characters, four species on both the Comoros and Mayotte, three species on the Comoros only and one species on Mayotte only. Two species, Dabulamanzia mayottensis sp. nov. and Nigrobaetis richardi sp. nov., are new to science; they are described and illustrated based on their nymphs. The nymph of Afroptilum bicorne (Ulmer, 1909) is described for the first time and its assignment to this species is discussed. The description of the previously endemic Malagasy species Potamocloeon (Aquaediva) freitagae (Gattolliat, 2001), is complemented based on the additional material from the Comoros and re-examination of the type material. A key to the nymphs of all species of Baetidae in the Comoros and Mayotte is provided and the biogeography of the family in this region is discussed.

Little is known about the species composition of earthworms in agroecosystems in South Africa even though earthworms provide soil ecosystem services and are useful biological indicators of changes in the habitats. Given the land use and management impact biodiversity, the aim of this study was to document earthworm species that occur under cultivated land in the KwaZulu-Natal Midlands. A survey of nine farms that practise conservation agriculture was carried out between 2018 and 2020. Twelve earthworm species belonging to four introduced families: Acanthodrilidae (Dichogaster bolaui), Rhinodrilidae (Pontoscolex corenthrurus), Lumbricidae (Aporrectodea caliginosa, Aporrectodea rosea, Aporrectodea trapezoides, Lumbricus rubellus, Octolasion cyaneum, Octolasion lacteum), Megascolecidae (Amynthas aeruginosus, Amynthas corticis, Amynthas gracilis, Amynthas rodericensis) and juveniles from an indigenous family Tritogeniidae were recorded from cultivated fields. The type of crop (habitat) affected both species richness and abundance of earthworms significantly. However, post hoc results showed differences in species richness between the soya and the maize only, with greater species richness in the maize. Our results demonstrate that habitat type has a major influence on communities of earthworms in agroecosystems.

The cicada genus Tugelana Distant, 1912 is monotypic and endemic to south-eastern Africa. Material was not available for a recent molecular phylogeny of its tribe, so its precise phylogenetic placement is unestablished. Consequently, a 627 bp sequence of the cytochrome oxidase gene was obtained and its candidate relatives identified as several species of Platypleura Amyot & Audinet-Serville, 1843 using the BOLD Identification System and NCBI Genbank’s BLAST. Bayesian inference analyses indicated that the type species, the Maputaland Orangewing Cicada Tugelana butleri Distant, 1912, is closely related to the Dune Koko Orangewing Cicada Platypleura zuluensis Villet, 1989, which has a geographical distribution that is parapatric with T. butleri and which has aberrant genitalia for a member of Platypleura. This pair of species is placed fairly deep within the African clade of Platypleura. We therefore formally recognized Platypleura Amyot & Audinet-Serville, 1843 as a senior synonym of Tugelana Distant, 1912, syn. nov., and assign T. butleri Distant, 1912 to Platypleura as Platypleura butleri (Distant 1912), comb. nov. The species occurs on the wooded grasslands of the Maputaland coastal plateau east of Lebombo Mountains and south of Maputo Bay. Its Extent of Occurrence is about 6360 km2, which would qualify it as Vulnerable under the IUCN’s classification criteria for conservation status.

The African endemic hover fly Meromacroides meromacriformis (Bezzi, 1915) (Syrphidae, Eristalinae) was described more than a century ago and its monotypic status established in 1927, but subsequent collections and publications are rare. Only the male has been described and nothing is known about its biology. We re-describe the male, including geographic variation, describe the female for the first time and provide the first DNA barcodes for the species. Despite the large range and observed variations, there is insufficient evidence to describe additional taxa in the genus. Biological observations are presented, which may shed some insight into this rare and enigmatic hover fly, whose known distribution now spans the Afrotropical Region.

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.
