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

AbstractThe new lichen genus Sergipea M. Cáceres, Ertz & Aptroot is described in the Roccellaceae, based on the new species Sergipea aurata M. Cáceres, Ertz & Aptroot from NE Brazil. The species was found in a remnant of Atlantic transition forest in Sergipe. It is similar in many respects to species of the genus Enterographa, but it is characterized by bright orange stromata, due to the presence of an anthraquinone, and a thallus with a somewhat byssoid hypothallus. Phylogenetically it is close to the genera Dichosporidium and Erythrodecton. The phylogenetic position of the generic type of Dichosporidium confirms the close relationship of the genus to Erythrodecton in the basal branch of the Roccellaceae. A new species of Enterographa is also described from NE Brazil. Enterographa rotundata E. L. Lima, M. Cáceres & Aptroot has solitary, round apothecia, which is unusual in this genus with mainly elongated apothecia or punctiform apothecia arranged in lines. It was found in Caatinga forest in Pernambuco.

In the course of the writing of the Flore de la Nouvelle-Calédonie treatment for Asclepiadoideae, Periplocoideae and Secamonoideae, several new species have already arisen partly due to more intensive field work and to a renewed interest in this group of plants. In December 2018, another striking and unorthodox new species was spotted and collected on the flanks of the Kopéto massif mining site. Because this new species has morphological characters from three genera (Dischidia, Gymnema and Marsdenia), further studies, especially molecular, were needed to assess its relationships. These studies show it as a member of one of the New Caledonian Marsdenia subclades. We herein propose to describe it as Marsdenia goromotoorum Gâteblé, Fleurot, Meve & Liede, the only species of Marsdenia in New Caledonia lacking both corolline and gynostegial coronas. It is a micro-endemic species with pinkish-red tubular flowers, growing on serpentines and known from only eight plants. Due to the anthropogenic fire threat, we propose to consider it as Critically Endangered.

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.

Species Descriptions

Brachycephalus is a fascinating genus of miniaturized frogs endemic to the Brazilian Atlantic Forest (Bornschein et al. 2016a). Given the many new species that have been recently discovered (20 species over the past 10 years [Frost 2017]) and their often microendemic distribution (see Bornschein et al. 2016a), there has been an increasing awareness about the need for more extensive field work to locate additional new species, to describe their geographical distributions, and to devise comprehensive efforts to ensure their conservation. In a recent correspondence in Zootaxa, Condez et al. (2017) singled out nine of those new species that have been described by our research group (Ribeiro et al. 2015; Pie & Ribeiro 2015; Bornschein et al. 2016b); two additional species (Ribeiro et al. 2017) were described after their paper was published. According to Condez et al. (2017), our species descriptions included “inadequate diagnoses, which lacked indispensable information for any further comparisons among species” (p. 395). Herein, we explore the extent to which their arguments would undermine the validity of those species.

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.

A New Species

Androlepis najarroi (Bromelioideae, Bromeliaceae), a third dioecious species identified in the subfamily, is proposed as new from the Chiapas Highlands and Veracruzan biogeographical provinces, southern Megamexico. The novelty is superficially similar to Aechmea lueddemanniana but features characteristics of Androlepis, such as unisexual flowers and apically divided filaments. Based upon available information on the species and current generic concepts, assigning this species to Androlepis might only be provisional. The present contribution includes distribution maps, iconography, an identification key to the species of Androlepis, and a preliminary evaluation of the conservation status of this new species.

To analyze the pattern of endemism of Eneopterinae crickets (Orthoptera, Grylloidea, Eneopteridae) in New Caledonia, available data sets have been completed by intensive field work and by the study of museum collections. Five new species of Agnotecous Saussure, 1878 (A. humboldti Robillard, n. sp., A. nekando Robillard, n. sp., A. minoris Robillard, n. sp., A. petchekara Desutter-Grandcolas, n. sp., A. pinsula Robillard, n. sp.) and one new subspecies (A. brachypterus pocquensis Desutter-Grandcolas, n. ssp.) are described here from Grande Terre and Île des Pins. These new data (1) enhance the richness of Agnotecous in New Caledonia, with a total of 20 known species for the genus; (2) complete the distributional data about species sympatry; (3) further document the distribution of the genus in the archipelago; and (4) confirm the acoustic properties of Agnotecous calling songs.

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.
