Characterization of seven microsatellite marker loci in a genus of Malagasy lemurs (Propithecus)

The sifakas (genus Propithecus) are large, diurnal, lemurs endemic to the island of Madagascar. Throughout the island, lemur species are particularly vulnerable to extinction due to relatively small geographical ranges (Martin 2000). Thus, understanding the taxonomy of these highly endangered primates is essential for taking appropriate conservation action. For this study we collected tissue samples from 68 wild sifakas representing various Propithecus species. Genomic DNA was isolated and polymerase chain reaction (PCR) amplification was carried out. We describe seven microsatellites found to be polymorphic and useful for analysis of the population genetics of sifakas.

Tricalycoside,a New Cerebroside from Tricalysia coriacea (Rubiaceae)

A new cerebroside, named as tricalycoside ( 1 ), was isolated from the CH₂Cl₂/MeOH (1:1) extract of twigs and leaves of Tricalysia coriacea using repeated silica gel open column chromatography followed by preparative TLC and Sephadex LH‐20, together with six known compounds ( 2 – 7 ). The structure of the new compound was determined by analysis of 1D‐ and 2D‐NMR, MS data, chemical conversion, and by comparison of these data with those from the literature. Tricalycoside ( 1 ) possessed a weak antibacterial activity against Klebsiella pneumoniae (MIC = 75 μg/mL).     

Sperm morphology in the Malagasy rodents (Muroidea: Nesomyinae)

The morphology of the spermatozoon of representative species of the subfamily Nesomyinae (Muroidea: Nesomyidae), a monophyletic group of rodents endemic to Madagascar, was examined by light and electron microscopy to determine the sperm head shape and tail length across the species. Marked interspecific differences were found to occur in both the form of the sperm head and length of the tail. The species that possess a sperm head with an apical hook, which largely contains acrosomal material, generally displayed longer sperm tails, and a species with a spatulate sperm head had the shortest tail. The association between sperm head shape and tail length mirrors that previously found in Eurasian and Australasian murine rodents. Thus, the repeated association between sperm head shape and tail length across these groups of muroid rodents clearly indicates a functional relationship between these two features. A comparison of sperm morphology of the nesomyines to that of related muroid rodents on the mainland of Africa suggests that the possession of an apical hook is the ancestral condition. J.

Pollination by fungus gnats in four species of the genus Mitella (Saxifragaceae)

The first example of pollination by fungus gnats in the eudicots is reported. The genus Mitella (Saxifragales) is characteristically produces minute, inconspicuous, mostly dull-coloured flowers with linear, sometimes pinnately branched, petals. To understand the function of these characteristic flowers, we studied the pollination biology of four Mitella species with different floral traits and different sexual expression: dioecious M. acerina , gynodioecious M. furusei var. subramosa , and hermaphroditic M. stylosa var. makinoi and M. integripetala. Flower-bagging experiments showed that wind pollination did not occur in the dioecious and gynodioecious species. Two years of observations of flower visitors at six study sites in Japan revealed that the principal pollinators of all four Mitella were specific species of fungus gnats (Mycetophilidae), which landed on the flowers with their long spiny legs settling on the petals. Characteristically, numerous pollen grains were attached to the fungus gnats in specific locations on the body. Although, on average, 1.3–2.6 fungus gnats visited each inflorescence per day, the fruit set of both bisexual and female flowers exceeded 63%. These results suggest that fungus gnats are highly efficient pollinators of Mitella spp., and that Mitella flowers are morphologically adapted to pollination by fungus gnats.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 144 , 449–460.     

Revision of the genus Adorodocia Brenske 1893 (Coleoptera: Scarabaeoidea: Rutelinae: Adoretini) endemic to Madagascar

Summary. The Adoretini of the Malagasy endemic genus Adorodocia Brenske 1893 is revised. Fourteen new species and one new subspecies are described and compared with their most closely related species: A. constricta n. sp., A. cuccodoroi n. sp., A. flava n. sp., A. liliae n. sp., A. marginata n. sp., A. peyrierasi n. sp., A. pseudoconstricta n. sp., A. pseudoflava n. sp., A. pseudostrigata n. sp., A. recta n. sp., A. robusta n. sp., A. sogai n. sp., A. vadoni n. sp., A. viettei n. sp. and A. vittaticollis flavipes n. ssp. The synonymy between Adoretus strigatus Waterhouse 1878, and Pseudadorodocia aenigma Arrow 1901, is confirmed. Thus, based on the results of this study, the genus Adorodocia includes 16 species, and one of them is represented by two subspecies. Diagnostic characters to separate the species in the genus deal mostly with the shape of parameres, color of body and legs, shape of pronotum and female eighth tergite, setation of pronotum and elytra. Key to species, diagnoses and distribution for each species are provided. Endophallus and female genitalia are illustrated for the first time for this genus.     

Molecular phylogeny and biogeography of Malagasy frogs of the genus Gephyromantis

The genus Gephyromantis is a clade within the Malagasy-Comoroan family Mantellidae composed of rainforest frogs that live and breed to varying degrees independently from water. Based on DNA sequences of five mitochondrial and five nuclear genes we inferred the phylogeny of these frogs with full taxon coverage at the species level. Our preferred consensus tree from a partitioned Bayesian analysis of 5843 base pairs of 51 nominal and candidate species supports various major clades within the genus although the basal relationships among these remain unresolved. The data provide strong evidence for the monophyly of the subgenera Gephyromantis (after exclusion of Gephyromantis klemmeri), Laurentomantis, Vatomantis, and Phylacomantis. Species assigned to the subgenus Duboimantis belong to two strongly supported clades of uncertain relationships. G. klemmeri, previously in the subgenus Gephyromantis, was placed with high support sister to the Laurentomantis clade, and the Laurentomantis + G. klemmeri clade was sister to Vatomantis. A reconstruction of ancestral distribution areas indicates a diversification of several subgenera in the northern biogeographic regions of Madagascar and the dispersal out of northern Madagascar for several clades.     

Review of the genus perama (Rubiaceae)

The nomenclatural and taxonomic history of the genusPerama Aubl. (Rubiaceae) is discussed. The major trends of evolution within the genus are characterized, and the sections of the genus are delimited. A new section,Diperama Kirkb. & Steyerm., is described. The distribution of the genus is updated, and centers of species concentration are indicated. A complete synonymy is given for the genus, and the type species cited. An artificial key to the species is given ; a new combination,P. parviflora (Standl.) Kirkb. & Steyerm., is mads; and three new species are described,P. harleyi Kirkb. & Steyerm.,P. irwiniana Kirkb. & Steyerm., andP. sparsiflora Standl. ex Steyerm. & Kirkb.     

Mussaenda yunnanensis sp. nov. (Rubiaceae), a new functionally dioecious species from Yunnan,China

Mussaenda yunnanensis, a new dioecious species of Rubiaceae from Yunnan Province, China, is described and illustrated. The new species can be recognized by its slender stem, congested‐cymose inflorescences and long corolla tubes. Differences between M. yunnanensis and two morphologically similar species (M. pubescens and M. antiloga) are presented. We also provide a key to all dioecious species of Mussaenda in China. The delimitation of the new species is further supported by molecular phylogenetic analyses based on eight plastid loci.

Four new species of the genus Cheimacheramus Barnard, 1934 from Madagascar (Trichoptera: Sericostomatidae)

The genus Cheimacheramus Barnard, 1934 Barnard, K.H. (1934), ‘South African Caddis-Flies (Trichoptera)’, Transactions of the Royal Society of South Africa, 21, 291–394.[Taylor &; Francis Online] , [Google Scholar] included only three species, one from South Africa and two from Madagascar. Four new Malagasy species are described herein: Cheimacheramus akandi sp. n., Cheimacheramus barnardi sp. n. and Cheimacheramus anjojorobensis sp. n. from the Anjojorobe Forest, Cheimacheramus madecassus sp. n. from the Lakato Forest and the Marojejy National Park. Diagnostic characters of the genus and species are discussed and illustrated. In Madagascar, these discoveries confirm the localization of the genus within the eastern evergreen forests.
