Abstract

The authors describe and illustrate Stigmatodon minimus, a new species with the smallest stature within the genus, and discuss its taxonomic affinities and conservation status. Furthermore, this new species is the only one, among all others with typical tubo-laciniate stigma type, to present diurnal anthesis, reddish-wine to purplish-wine bracts, and unappendaged white petals, contrasting with the morphological characteristics of other previously known species of Stigmatodon s.str. The new species is closely to S. amadoi, with which it is compared, and considered a microendemic, Vulnerable [VU: D2] species due to its restricted habitat, reduced population size, and threats from ornamental rock mining.

Abstract

During the taxonomic revision of the genus Stigmatodon, we found an unknown epilithic mat-forming species, morphologically close to S. belloi, on vertical granitic surfaces on inselbergs in southern Espírito Santo state, Brazil. We described and illustrated the new species, including a comparative analysis of characters that distinguish it from similar species. We also provide data on habitat, ecology, geographical distribution and evaluation about its threat of extinction according to the criteria of the IUCN.

Abstract

The authors describe, discuss, and illustrate Tillandsia oliveirae, a new species from the inselbergs of the Caatinga biome in the municipality of Itatim, Bahia, Brazil. The new species is similar to T. hofackeri, differing by morphological characters such as larger size of the plant, longer peduncle, more laxly arranged leaves, which are more numerous, and whitish petals. It is an endemic species with a restricted area of distribution, being considered critically endangered (CR) due to illegal extractivism, specifically for regional and international trade.

Abstract

A new species of Aloe, A. uigensis (Asphodelaceae subfam. Alooideae), is described from northwestern Angola. It is a non-proliferous, single-stemmed species that bears narrowly elongated, acuminate racemes with orange to pale reddish flowers. Aloe uigensis is compared to some long-known as well as recently described species of Aloe from Angola, but does not have close relatives with which it can be confused in the country.

 Abstract

Four species of the genus Panaspis – P. cabindae, P. wahlbergii, P. maculicollis and P. mocamedensis – are currently known from Angola. The analysis of recently collected specimens from Serra da Neve Inselberg, an isolated mountain located in northern Namibe Province, revealed unexpected taxonomic diversity in the group. Using an integrative taxonomy approach based on morphological and DNA sequence data, with both mitochondrial (16S) and nuclear (RAG-1) genes, we were able to distinguish two distinct populations, described here as two new species, Panaspis ericae sp. nov. and P. mundavambo sp. nov. Both species are assumed to be endemic to the inselberg. This reinforces our notion of southwestern Angola as a hotspot of skink diversity, and highlights the urgent need for the conservation of Serra da Neve.

 Panaspis ericae sp. nov.

Etymology: The specific epithet “ericae” is formed in the genitive singular and is feminine. It is given in honor of Erica Tavares (1997–), an Angolan biologist and conservationist. Through her work in the Angolan environmental platform “Eco Angola” (of which Erica is a co-founder), Erica has revolutionized the Angolan conservation and ecological discourse, providing opportunities for members of the Angolan civil society, students, and young researchers to learn, debate and contribute to environmental causes. We suggest “Erica’s Snake-Eyed Skink” and “Lagartixa da Manta-Morta de Erica” as the English and Portuguese common names, respectively, for this species.

 Panaspis mundavambo sp. nov.

Etymology: The specific epithet “mundavambo” refers to the Mukwando (local tribe) name for Serra da Neve Inselberg (Opunda Mundavambo), to which the species is endemic, and is applied here as a substantive in apposition. We propose the English vernacular name “Serra da Neve Snake-Eyed Skink” and the Portuguese vernacular name of “Lagartixa da Manta-Morta da Serra da Neve”.

Summary

Praxelis cleggiae (Compositae: Eupatorieae: Praxeliinae) is described and illustrated from the granite inselbergs (upon which it is most common), and on road crown chippings on old roads, in the Departamento de Santa Cruz, Bolivia; it has a disjunct distribution and is also found on the Serranía San Simón, in the San Ignacio Schist belt, Departamento de Beni. Material of this species was mostly determined as P. insignis (Malme) R.M.King & H.Rob., a Brazilian species, described from the metamorphosed sandstone of what is now the Parque Nacional da Chapada dos Guimarães in Mato Grosso State. The two species have some superficial resemblance, but differ significantly in plant size, internode length (relative to leaf length), branching, leaf shape and size, phyllaries, achenes and pappus. The total number of species of Praxelis recognised in Bolivia is now seven, and 20 species in the genus worldwide.

Praxelis cleggiae D.J.N.Hind & S.L.Edwards, sp. nov.

RECOGNITION. Praxelis cleggiae is similar to P. insignis in that both species are procumbent and spreading, commonly have a single capitulum per inflorescence (if terminal) or inflorescence branch, and possess inconspicuously bracteolate pedicels. Praxelis cleggiae is distinguished from P. insignis in possessing markedly longer internodes (c. 2 – 9 cm vs c. 0.3 – 0.8 cm), with leaves scarcely longer than internode (vs leaves c. 3 – 6+ times longer than ...

ETYMOLOGY. The species is named after Rosemary (Rosie) Clegg, formerly TIPAs Bolivia Co-ordinator, at RBG, Kew, now a post graduate student being co-supervised by the first author of this paper. Rosie first brought the issue of this species to the attention of the first author when she began assessing the species for Red Data listing, at which point a critical assessment was made of the material.

Abstract

A new species of Krenakanthus, a member of the bromelioid “Cryptanthoid complex”, is described based on plants discovered through collaborative citizen science. Krenakanthus ribeiranus and its only congener K. roseolilacinus are endemic to the “João Pinto Center of Biodiversity”, a still poorly explored region with Campos Rupestres and associated vegetation in the Rio Doce Valley, in eastern Minas Gerais state, Brazil. The unusual combination of morphological characters of K. ribeiranus, highlighted by plant delicacy and almost all leaf and flower parts covered by uniseriate, hair-like trichomes, is illustrated and discussed in comparison with K. roseolilacinus, including leaf and seed anatomy, as well as pollen morphology. This micro-endemic species is assessed as Critically Endangered, reinforcing the need for strategy to protect the biodiversity of the region. The morphology of the new species validates and strengthens the diagnostic flower characters used in the circumscription of Krenakanthus, suggesting as secondary diagnostic characters the habit, stature, and leaf conformation.

Abstract

Behuria mestrealvarensis (Melastomataceae) from the state of Espírito Santo, Brazil, is described, illustrated and compared with B. capixaba, the species most similar to it. Behuria mestrealvarensis differs from B. capixaba by the glabrous petioles and hypanthia, by the solitary flowers or these in simple or compound triads up to 7 flowers, elliptic bracteoles almost the same size of the pedicel and hypanthium, sepals with eciliate margins and ovary apex with trichomes up to 0.5 mm. It occurs in a single locality, on an isolated, ca. 800m elev. inselberg. Due to its restricted occupancy area, fragmented landscape and poor habitat quality, this species must be considered as Critically Endangered according to IUCN criteria.

Elle se distingue des autres espèces malgaches du genre par son port herbacé avec des tiges richement ramifiées et touffues, décombantes et dressées, des plantes glabres à glabrescentes et sa capsule obovoïde-acuminée. Une description détaillée de l'espèce est fournie, accompagnée d'illustrations et d'une clé d'identification des espèces malgaches du genre. La nouvelle espèce est considérée comme “En danger” selon les Catégories de la Liste rouge de l'UICN.

ABSTRACT

During a recent survey of the Serra da Neve inselberg in south-western Angola, a population of legless skinks of the genus Acontias was found. Only three species of this genus have been recorded for the country so far – A. occidentalis, A. kgalagadi and A. jappi. Using an integrative approach and combining molecular and morphological data we found that the Serra da Neve population represents a new species, closely related to species such as A. percivali and some members of the A. occidentalis species complex. In this paper, we describe this population as a new species, Acontias mukwando sp. nov. and provide brief comments on its conservation and biogeography.

RESUMO: No decorrer de um levantamento herpetológico da ilha-montanha da Serra da Neve no sudoeste de Angola, descobriu-se uma população de escincos-lança do género Acontias. Apenas três espécies deste género foram até agora registadas para Angola - A. occidentalis, A. kgalagadi and A. jappi. Adotando uma abordagem integrativa e combinando dados morfológicos e moleculares, os nossos resultados indicam que a população da Serra da Neve representa uma nova espécie, com relações próximas a outras espécies rupícolas tais como A. percivali e membros do complexo de espécies A. occidentalis. Neste artigo descrevemos esta população como uma nova espécie, Acontias mukwando sp. nov. e apresentamos breves comentários sobre a sua conservação e biogeografia.
