Species Descriptions

The genus Nolletia has never been revised. There is no key available to all the species, making identification extremely difficult and resulting in misidentifications. For only a few species there are fairly comprehensive species descriptions available. A complete revision of the genus was undertaken, a key to all the species was drawn up, full descriptions were made and distribution maps were provided. Five new species were described: N. annemarieae, N. annetjieae, N. vanhoepeniae, N. jeanettae and N. welmaniae. One southern African species (N. arenosa) is synonymized under N. chrysocomoides. The genus could be divided into two groups on the grounds of the cypsela morphology: one group has oblong epicarpic cells arranged in parallel rows, seen in surface view, while the other group has circular to elliptic epicarpic cells, seen in surface view. One species was reported to be poisonous to stock. It was previously identified as N. gariepina but is described here as one of the new species, N. vanhoepeniae.

Species Descriptions

The tribe Sisyphini sensu stricto Mulsant, 1842 comprises only three genera, the widespread Sisyphus Latreille, 1807 and Neosisyphus Müller, 1942, and the Mauritius endemic, Nesosisyphus Vinson, 1946. In southern Africa, Sisyphus and Neosisyphus are represented by five species groups in each genus. Together, they comprise a total of 33 valid species, of which six are new: Sisyphus auricomus sp. n; Sisyphus australis sp. n ; Sisyphus bicuariensis sp. n; Sisyphus inconspicuus sp. n; Sisyphus swazi sp. n; and Neosisyphus tembyi sp. n. A further Southern African species, Sisyphus crispatus Gory, 1833, is proposed as a nomen dubium. Sisyphus natalensis Balthasar, 1968 (syn. n), and Sisyphus bornemisszanus Endrödi, 1983 (pars) (syn. n) are made synonyms of Sisyphus sordidus Boheman, 1857. Lectotypes and paralectotypes are designated for Sisyphus costatus (Thunberg, 1818); Sisyphus seminulum Gerstaecker, 1871; Sisyphus nanniscus Péringuey, 1901; Sisyphus transvaalensis Péringuey 1901; Neosisyphus spinipes (Thunberg, 1818) and Neosisyphus barbarossa (Wiedemann, 1823). Diagnoses, photographs of habitus and male genitalia, lists of examined material and distribution maps are presented for all species. An identification key to the southern African sisyphine species is provided.

African Clade

Schoenus is a morphologically complex, predominately austral genus. The taxonomy of the southern African clade of Schoenus has received recent attention with the transfer of 24 southern African species into Schoenus from Tetraria and Epischoenus in 2017. A taxonomic revision in early 2018 both revised the taxonomy of the Schoenus compar—Schoenus pictus and allies group, as well as described three new species endemic to the Cape Floristic Region of South Africa. In addition, seven new species were described in early 2019 as part of a revision of the Schoenus cuspidatus group. Here, we build on this recent taxonomic work by providing descriptions for three new species (Schoenus bracteosus, Schoenus comparoides and Schoenus triticoides). We also provide a new name at species rank for a taxon previously named as a variety of Tetraria sylvatica. We present detailed species descriptions, distribution maps and an updated identification key.

Area Of Occupancy

A revision of the 45 species of the pantropical genusXylopiain Tropical Africa includes descriptions of six new species and a new section of the genus. The fruits and seeds ofXylopiashow specializations that promote vertebrate dispersal, primarily by hornbills and monkeys. Over half of the African species have an Area of Occupancy (AOO) less than 80 km2, suggesting that they are in need of protection. African species are classified into five sections. Section Neoxylopia , with four species, is centered in the Guineo-Congolian Region and includesX.globosasp. nov.Section Ancistropetala, with three species, occurs in the same region. Both of these sections are endemic to Africa. Section Xylopia, which extends to Madagascar and the American tropics, has only a single species in Africa,X.aethiopica. The three species of section Verdcourtiasect. nov.are restricted to the East African coast and Madagascar. The largest number of African species, (34) belong to section Stenoxylopia, in which the seeds lack the arils found in the other sections and instead have a fleshy sarcotesta. Section Stenoxylopia is divided into two informal groups, one centered in eastern and southern Africa (X.odoratissimagroup) and the other centered in the wetter forests of western and central Africa (X.acutifloragroup). Five new species are described in section Stenoxylopia:Xylopianiloticasp. nov.from Sudan, South Sudan, and Uganda,Xylopiacalvasp. nov.from Nigeria and Cameroon, which is allied toX.phloiodora, andXylopiamonticolasp. nov.from Nigeria and Cameroon,X.pirataesp. nov.from Ivory Coast and Ghana, andX.unguiculatasp. nov.from Gabon. The latter three species are segregates of the formerXylopiaacutifloras. l. One new combination is made at the species level,X.shirensiscomb. nov.Keys, descriptions, illustrations, distribution maps, and an index to numbered collections document diversity and assist with species identification. The nameUnonaoliverianaBaill. was found to pre-date the nameUnonalepidotaOliv., requiring the combinationMeiocarpidiumoliverianumcomb. nov.

Species Descriptions

Kanakomyrtus (Myrtaceae) is a newly described genus endemic to New Caledonia. Kanakomyrtus myrtopsidoides, the generic type, is transferred from Eugenia. Five new species are described: K. mcphersonii, K. revoluta, K. dawsoniana, K. prominens, and K. longipetiolata. The genus occurs in forests at elevations between 500–1,600 m on the relatively mesic windward side of the Grande Terre. It is distinct from other baccate genera of Myrtaceae by a combination of linear stylar lobes, densely glandular stamens and stigmas, and a short but densely hoary indumentum that is brownish when dry. The thinly membranous partitions that partially extend between the seeds of some species suggest a close relationship to Archirhodomyrtus and some species traditionally placed in Rhodomyrtus and Octamyrtus. Four of the six species have unisexual flowers, but much additional field work is needed to assess the reproductive biology of the genus. Following IUCN guidelines, four species are proposed as either Endangered or Critically Endangered, whereas the remaining species are considered Vulnerable and of Low Concern. Species descriptions, illustrations, distribution maps, and keys to species of the genus and related taxa of baccate Myrtaceae from New Caledonia are included.

A New Species

A new species of Obuloides, Obuloides crinitus sp. nov., is described based on females and males collected from the galls and twigs of Grewia occidentalis (Tiliaceae) in South Africa. Obuloides crinutus is closely related to O. namibiensis and O. rajamohani but can be distinguished by the finely granulated shields, a character that no other species of this genus has. Another notable difference is the length of prodorsal setae v2, which are longer and more strongly serrated compared to the other species of this genus which have very short and mostly smooth setae. Males of this species lack setae d1. A key to known species is provided.

The southern African species of the water beetle genus Ochthebius Leach, 1815, are reviewed. Eight new species are described, and new collection records are given for eight previously described species, based on the examination and databasing of 8,919 specimens from 253 localities/events. Male genitalia of the new species are illustrated, and high resolution habitus images of the holotypes of new species are provided. Distribution maps are given for the 18 species of Ochthebius now known from southern Africa, including Namibia, South Africa, Lesotho, Zimbabwe, the extreme southern part of Angola, and the southern part of Mozambique. New species of Ochthebius are: O. anchorus (South Africa, KwaZulu-Natal Province, Oribi Gorge); O. bicomicus (South Africa, Western Cape Province, 22 mi. N. Nelspoort); O. bupunctus (Namibia, Kaokoveld, Kunene River, Swartbooisdrift); O. endroedyi (South Africa, North West Province, Barberspan); O. granulinus (South Africa, Western Cape Province, Elandsdrift); O. involatus (South Africa, Western Cape Province, near Kommetje); O. sitiensis (Namibia, Okau Fountain, 12.5 km inland); and O. zulu (South Africa, KwaZulu-Natal Province, Nqutu).

The taxonomy and systematics of the genus Digitonthophagus Balthasar (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) is revised. A detailed study of the male genitalia combined with external morphology suggests that the variability, previously recognized, for D. gazella is hiding a species complex within the Afrotropical region and the Arabian Peninsula. The current study recognizes 16 species; 13 from the Afrotropical region and Arabian Peninsula and three from the eastern portion of the Saharo-Arabian region and the continental Indomalayan region. Species are organized into six species groups based on the results of the morphology-based phylogenetic analysis. The following 12 species are described as new: D. aksumensis Génier new species; D. biflagellatus Génier new species; D. dilatatus Génier new species; D. eucatta Génier new species; D. falciger Génier new species; D. fimator Génier new species; D. namaquensis Génier new species; D. petilus Génier new species; D. sahelicus Moretto new species; D. uks Génier new species; D. ulcerosus Génier new species; and D. viridicollis Génier new species. In order to stabilize nomenclature, lectotypes are designated for Scarabaeus bonasus Fabricius, 1775; Scarabaeus catta Fabricius, 1787, and Onthophagus gazella lusinganus d’Orbigny. A neotype is designated for Scarabaeus dorcas Olivier, 1789 whose status and synonymy need to be altered in order to clarify the status of Scarabaeus gazella auctorum, the widely introduced species with economic importance. A naming scheme is presented for the sclerites of the internal sac. External and male genitalia are illustrated and distribution maps are provided for each species.

After our taxonomic revision of Ootheca Chevrolat, 1837, and the description of Oothecoides Kortenhaus & Wagner, 2011 and Ootibia Kortenhaus & Wagner, 2012, it became clear that a further four galerucine species, closely related to the above named taxa, form a distinct monophyletic group, that constitutes a new genus, Oosagitta gen. nov. with O. anningae sp. nov., O. geescheae sp. nov., O. melanopicta sp. nov. and O. thomasi sp. nov.. Exosoma angolensis Laboissière, 1939, the type species of the new genus, and Ergana minuta Laboissière, 1937 are newly transferred to Oosagitta gen. nov. All species of Oosagitta gen. nov. are characterized by a broad body and pronotum, a more or less convex dorsum and short legs, and as such are most similar to the other above named genera. The antennae of Oosagitta gen. nov. are distinctly longer than those of Ootheca, Oothecoides and Ootibia. Genital structures of the males allow a reliable identification of the genus. (Re-)descriptions are given for all species, including semi-schematic illustrations depicting the habitus outline, shape of the basal antennomeres and the median lobe. Photographs of the name-bearing types and distribution maps are provided.
