Taxonomic studies of Glochidion (Phyllanthaceae) from the Indo-China Peninsula (I): G. shanense, a new species from Myanmar.

ABSTRACT: Based on morphological studies performed on live plants in the field and specimens deposited in herbaria, a new species, Glochidion shanense Gang Yao & Shixiao Luo (Phyllantheae, Phyllanthaceae), is here described and illustrated. The species is morphologically most similar to G. ellipticum Wight, but can be distinguished from the latter by having hairy branchlets, longer pedicels, uniseriate and narrowly triangular sepals of female flowers, 4-5-locular ovaries, stout and cylindric persistent style on fruits.

Taxonomic studies of Glochidion (Phyllanthaceae) from the Indo-China Peninsula (II): The identities of G.anamiticum and G.annamense.

Project description:The names Glochidionanamiticum (Kuntze) Kuntze ex Merrill and G.annamense Beille were previously reduced to synonyms of G.eriocarpum Champ. ex Benth. However, literature examination and morphological comparison suggest that G.annamense is conspecific with G.anamiticum and the species can be readily distinguished from G.eriocarpum by its styles connate into a long cylindric column and up to 3 mm long, ovaries usually 3-locular, stigma usually 3-lobed, capsules pubescent and usually 6-grooved, persistent styles 3?4 mm long. Thus, the specific status of G.anamiticum is here reinstated and G. annamense is treated as its synonym.

Taxonomic revision of the genus Glochidion (Phyllanthaceae) in Taiwan, China.

Project description:A comprehensive taxonomic revision of the genus Glochidion J.R. Forst. & G. Forst. from Taiwan in China was carried out based on the examination of herbarium specimens and filed investigations. Eight species and three varieties are recognized, including a new species endemic to Taiwan, G. lanyuense Gang Yao & S.X. Luo, which is described and illustrated. Three names, viz. G. chademenosocarpum Hayata, G. kusukusense Hayata, and G. ovalifolium F.Y. Lu & Y.S. Hsu, are reduced to the new synonyms of G. rubrum Blume, G. lanceolatum Hayata, and G. ellipticum Wight, respectively. Two names, viz. G. lanceolatum Hayata and G. suishaense Hayata, are lectotypified here. A key to the Glochidion species in Taiwan is provided.

Isolation and characterization of 11 microsatellite markers for Glochidion acuminatum (Phyllanthaceae).

Project description:UNLABELLED: PREMISE OF THE STUDY:Microsatellite markers were developed for Glochidion acuminatum (Phyllanthaceae) to investigate pollen dispersal distances and thereby to assess the effectiveness of specialized Epicephala moths as pollinators. • METHODS AND RESULTS:Using next-generation sequencing, 11 polymorphic microsatellite primer pairs were developed for G. acuminatum. The primer pairs were tested on 49 individuals from two populations in Japan. The number of alleles per locus ranged from two to 13, and the expected heterozygosity ranged from 0.12 to 0.85. Probability of identity for all loci combined was lower than 1.27 × 10(7). • CONCLUSIONS:The microsatellite markers developed in this study will be useful for evaluating the benefit of specialized Epicephala moth pollination to Glochidion plants.

A taxonomic study on semifumata species-group of Fissocantharis Pic, with description of six new species from China and Myanmar (Coleoptera, Cantharidae).

Project description:The cantharid Fissocantharis semifumata species-groupis reviewed. Fissocantharis semifumata (Fairmaire, 1889) is redescribed and illustrated. The type series of Fissocantharis fissa (Wittmer, 1997) is shown to consist of 3 species and clarified, except the holotype, the two paratypes become invalid. Fissocantharis grahami (Wittmer, 1997) is attributed to this species group. Six new species are described and illustrated, Fissocanthais yuisp. n. (CHINA: Yunnan), Fissocantharis semimetallicasp. n.

Taxonomic revision and phylogenetic position of the flying squirrel genus Biswamoyopterus (Mammalia, Rodentia, Sciuridae, Pteromyini) on the northern Indo-China peninsula.

Project description:The flying squirrel genus Biswamoyopterus (Rodentia: Sciuridae: Pteromyini) was once considered to contain three species, Biswamoyopterus biswasi from northeastern India, B. laoensis from central Laos and B. gaoligongensis from southwest China, all identified from morphological characteristics of one or two specimens. However, based on similar morphological characteristics of two samples of the genus Biswamoyopterus collected recently from northern Laos and northern Myanmar, and the small genetic distances on mitochondrial DNA and nuclear DNA between them, the results strongly support these two samples as representatives of the same species. The phylogenetic analyses strongly support Biswamoyopterus as an independent genus of Pteromyini, as a sister group to Aeromys. Biswamoyopterus biswasi is distributed in the northern Indo-China peninsula, where it is exposed to a series of threats, such as intense hunting activity, illegal trade, and rapid habitat loss; this should warrant its classification as critically endangered according to the International Union for Conservation of Nature (IUCN) Red List criteria. Here, the molecular data for genus Biswamoyopterus and two new specimen records from northern Laos and northern Myanmar are presented.

Multiple Coexisting Species and the First Known Case of a Cheater in Epicephala (Gracillariidae) Associated with a Species of Glochidion (Phyllanthaceae) in Tropical Asia.

Project description:Glochidion plants and Epicephala moths played different roles and kept the balance in the mutualism. We studied the four coexisting Epicephala species on Glochidion sphaerogynum in detail and reconstructed the phylogenic tree of 40 Gracillariidae species. The results showed that one of them (Epicephala impolliniferens) did not pollinate G. sphaerogynum, because of lacking the specialized structure of carrying pollen. These results suggested that E. impolliniferens acted as a 'cheater' in the system. The phylogenetic analyses suggested that E. impolliniferens derived from a pollinating species, and had secondarily gave up the ability to pollinate. This is a typical phenomenon of mutualism reversal. The phenomenon exhibits the co-evolutionary diversification under selection pressures.
