A remarkable new Veturius (Veturius) of the Brazilian Central Amazonas,with an inventory of the genus in Brazil (Coleoptera: Passalidae)

A new species of Veturius (Veturius) Kaup, of Brazil, Central Amazonas, lower basin of Urucu, Tefé and Coari, is described and illustrated. V. urucuensis n. sp. belongs to the “cephalotes” species group, and has an external autapomorphy for the family Passalidae: a large tuft of setae on the medioposterior area of the metasternum. The species is closely allied to V. jolyi Boucher, 2006, from the Brazil-Venezuela-Guyana border. The peculiar endemism of the new species suggests an intra-continental island vicariance into the Amazon Basin. No similar process was known in the large genus Veturius. A complete inventory of the 22 Veturius species in Brazil is given, with their distribution, and following the previously established monophyletic species groups. From Brazil, two species are newly reported, V. (Ouayana) guyanensis Boucher, 2006 (Pará) and V. (O.) dominicae Boucher, 2006 (Roraima), and one species is confirmed, V. (O.) unicornis Gravely, 1918 (Amazonas). New details are given on some other Brazilian Veturius.     

Testing the regeneration niche hypothesis with Gesneriaceae (tribe Sinningiae) in Brazil: Implications for the conservation of rare species

The germination requirements of sexually reproducing plants are regulated by environmental factors such as temperature. Those factors acting at the germination phase are part of the regeneration niche, which is fundamental in the processes that contribute to habitat suitability and geographic distribution. We tested the hypothesis that rarity is associated with regeneration niche in three species of plants in the family Gesneriaceae (tribe Sinningieae), Sinningia rupicola (Mart.) Wiehler, Paliavana sericiflora Benth and Sinningia allagophylla (Mart.) Wiehler, which vary in their distribution and habitat specificity but share a small zone of sympatry in rocky fields south of Belo Horizonte in Minas Gerais, Brazil. The regeneration niche was tested using a seed germination experiment under controlled light conditions at seven fixed temperatures (10–40°C at 5°C intervals). Each of the three species germinated differently at the various temperatures. The species with the smallest geographic range, S. rupicola, also had the most restricted germination: germination peaked at 15°C when relatively few seeds germinated (45%), and even fewer germinated at other temperatures. The regeneration niche was wider in P. sericiflora and wider still in S. allagophylla, with germination greater than 90% between 15–25°C and greater than 80% between 15–30°C, respectively. Our germination results provide qualified support for the hypothesis of correlation of the regeneration niche with geographic distribution of related plant taxa, with important conservation implications for rare and endangered species.

The genus Cyrtomium (Pteridophyta: Dryopteridaceae) in Africa and Madagascar

The fern genus Cyrtomium (Dryopteridaceae) in Africa and Madagascar is reviewed. Until now, a single Cyrtomium species ascribed to either C. caryotideum or C. micropterum (the latter often considered to be a variety of the former) was recognized for the region. This study shows that three Cyrtomium species occur in the region. One, C. falcatum, is not native to the African or Madagascan region, but has become naturalized in various parts of South Africa and Réunion. Two, formerly considered as a single taxon and confused with C. caryotideum and Indian forms thereof, are described as new – C. luctuosum from Madagascar, East, West and South Africa and C. pseudocaryotideum from South Africa. © 2011 The Linnean Society of London, Botanical Journal of the Linnean Society, 2011, 167 , 449–465.

Physiological characteristics underpinning successful cryopreservation of endemic and endangered species of Bromeliaceae from the Brazilian Atlantic Forest

The germination requirements and the basis of the optimal water content before and after cryopreservation were studied for ten endangered Brazilian species of Bromeliaceae. Constant and alternating temperature regimes were used to determine the best conditions for seed germination. The relationship between seed water content and relative humidity was evaluated using water sorption isotherms at 15 °C. Seeds were cryostored at four water contents (3, 5, 7 and 9%) and three storage periods (0, 180 and 365 days), and loss in viability and vigour were estimated. Fresh seeds of all species showed maximum germination in < 30 days at temperatures between 20 and 30 °C, indicating the absence of a physical/morphological dormancy. A sigmoidal relationship between seed water content and relative humidity was observed with no apparent differences in sorption characteristics among the species. The optimum water content for cryopreservation of most of these species was c. 7%. Ultra‐drying (3% seed water content) had a detrimental effect on seed viability and vigour. Our experiments suggested orthodox storage behaviour for all species of Bromeliaceae examined as they are able to survive desiccation and freezing. This study has shown the feasibility of ex situ conservation in seed cryobanks of endangered bromeliads from the Brazilian Atlantic Forest to support future reintroduction of these species in nature. © 2014 The Linnean Society of London, Botanical Journal of the Linnean Society, 2014, 176 , 567–576.

Taxonomic revision and phylogenetic analysis of the enigmatic scorpionfly genus Leptopanorpa MacLachlan (Mecoptera: Panorpidae)

The representatives of the enigmatic genus Leptopanorpa MacLachlan are characterized by exaggeratedly elongated male abdomens and are likely endemic to Java and Sumatra, Indonesia. Here, we present a taxonomical revision of 14 species of Leptopanorpa, including two new species: Leptopanorpa linyejiei sp. n. from West Java and Leptopanorpa majapahita sp. n. from East Java. A key to species of Leptopanorpa is provided. Leptopanorpa sieboldi MacLachlan is treated as a junior synonym of Leptopanorpa charpentieri (Burmeister), and Leptopanorpa pi decorata Lieftinck is synonymized with Leptopanorpa pi (van der Weele). Leptopanorpa peterseni Lieftinck is reported from Bali for the first time. In order to unravel the phylogeny of Leptopanorpa and other groups with elongated male abdomens, maximum parsimony and Bayesian inference analyses were performed based on 61 morphological characters and partial sequences of one nuclear gene (28S ribosomal RNA) and two mitochondrial genes (cytochrome c oxidase subunits I and II). Thirty-three species in Panorpoidea were selected as in-group taxa and two species in Choristidae as out-group taxa. The results highly support a monophyletic Leptopanorpa, which nests within a paraphyletic Neopanorpa van der Weele. Both parsimonious and Bayesian results suggest that Leptopanorpa can be divided into four subclades. We elucidated the evolutionary history of Leptopanorpa with regard to the paleogeological events of Sundaland and corroborated the multiple origins of elongated male abdomens in Panorpoidea. We also hypothesized that the ventral hook on the male abdominal sternum VI of L. linyejiei sp. n. is very likely used to control the female's abdomen during copulation.     

Revision of the genus Fascicularia Mez (Bromeliaceae)

The genus Fascicularia Mez is revised as part of a study of the Bromeliaceae for the Flora de Chile. Morphological and anatomical investigation of herbarium and living material from cultivation as well as DNA-studies (RAPDs) in cultivated material has led us to conclude that Fascicularia bicolor (Ruiz & Pav.) Mez, the only one species in the genus, comprises two subspecies which are distinguished by their leaf anatomy and morphology.     

A taxonomic revision and pollen morphology of the genus Dendrokingstonia (Annonaceae)

The genus Dendrokingstonia (Annonaceae) is taxonomically revised and palynologically studied. Three species are recognized, one of which, D. gardneri , is described as new to science. One new combination, D. acuminata , is made. The genus occurs from southern Thailand to Peninsular Malaysia and Sumatra. On the basis of macromorphology and pollen characters, it is considered to be related to Monocarpia. Both genera show a combination of macromorphological characters that is rare in the family, i.e. considerably enlarged stigmas, leaves with percurrent tertiary veins, a highly reduced number of carpels per flower and relatively large monocarps with a thick, hard wall. Scanning and transmission electron microscopy show that the pollen grains of Dendrokingstonia and Monocarpia are monosulcate monads with a columellate infratectum and a more or less bulging intine at the sulcus. © 2011 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 168 , 76–90.

Melissopalynology in an area of Atlantic Forest (northeast region,Brazil)

Apis mellifera is a bee that was introduced to Brazil and has adapted very well to the climate conditions and vast diversity of plants that exist in the country. In the northeast region of Brazil, beekeepers make use of the association between bees and plants by selling various bee products, notably honey. One way to identify species visited by bees in an area is by the pollen in its products. Based on this, 16 samples of honey were analysed, which were collected over a period of two years and obtained from an apiary in the Atlantic Forest biome in the municipality of Entre Rios (Bahia). In addition, climatic data (precipitation and temperature) of the region were obtained for the months sampled. The average temperature of the region during the collection months varied from 22 to 28 °C. The highest precipitation recorded in the region was 133.7 mm³ and the lowest was 0.3 mm³. Seventy pollen types were found. The family Fabaceae was notable, with ten pollen types, of which Mimosa pudica was the most important with a high frequency of occurrence and distribution. The Eucalyptus (Myrtaceae) pollen type also had a high frequency of occurrence and distribution. In addition, pollen types corresponding to species that supply nectar to bees were identified, which contributes to the large diversity of bee plants for Apis mellifera in the study area.
