چکیده

Recent molecular phylogenetic studies and reevaluation of morphological characters have led to the inclusion of Glochidion within a broader delimitation of Phyllanthus. It is necessary for preparation of the Vascular Flora of the Marquesas Islands to make new combinations for the Marquesan species. We also provide the relevant combinations and listing of all of the currently accepted species of Phyllanthus on Pacific oceanic islands for a total of 69 native species in oceanic Pacific islands. Glochidion tooviianum J. Florenceis here placed into synonymy of Phyllanthus marchionicus (F. Br.) W. L. Wagner & Lorence based on new assessment of recently collected specimens from Nuku Hiva. Glochidion excorticans Fosberg var. calvum Fosberg is placed into synonomy of Phyllanthus ponapense (Hosokawa) W. L. Wagner & Lorenceand Glochidion puberulum Hosokawa and Glochidion excorticans Fosberg are placed in synonymy of Phyllanthus senyavinianus (Glassman)W. L. Wagner & Lorence based on new study of all Micronesian specimens available to us. No infraspecific taxa are recognized within Phyllanthus pacificus of the Marquesas Islands. Species already with valid names in Phyllanthus are also listed for completeness and convenience. Brief distributional comments are given for each species. We propose new names for species for which a new combination is not possible: Phyllanthus florencei W. L. Wagner & Lorence, nom. nov., Phyllanthus mariannensis W.L. Wagner & Lorence, nom. nov., Phyllanthus otobedii W. L. Wagner & Lorence, Phyllanthus raiateaensis W. L. Wagner & Lorence, Phyllanthus st-johnii W. L. Wagner & Lorence, nom. nov., and Phyllanthus vitilevuensis W.L. Wagner & Lorence, nom. nov. We provide information for four additional naturalized species within the region (Phyllanthus amarus, Phyllanthus debilis, Phyllanthus tenellus, and Phyllanthus urinaria). The name Glochidion ramiflorum widely applied to Pacific island populations is here considered to be a species further west in the Pacific with all of the oceanic species here referred to several regional species.

Non-congruent colonizations and diversification in a coevolving pollination mutualism on oceanic islands.

A challenge for coevolutionary theory is how different types of interaction influence the diversification of coevolving clades. Reciprocal specialization is characteristic of certain coevolving, mutualistic interactions, but whether this specialization seen in ecological time constrains changes in patterns of interaction over evolutionary time remains unclear. Here, we examine the co-radiation ...

Three new species of Epicephala Meyrick (Lepidoptera, Gracillariidae) associated with Phyllanthus microcarpus (Benth.) (Phyllanthaceae)

Three new species of Epicephala Meyrick, 1880 are described based on specimens reared from fruits of Phyllanthusmicrocarpus (Benth.): Epicephalamicrocarpa sp. n. and Epicephalalaeviclada sp. n. from Guangxi and Hainan, and Epicephalatertiaria sp. n. from Guangdong and Guangxi. Photographs of adults and illustrations of genital structures are provided.

Repeated colonization of remote islands by specialized mutualists.

Mutualisms are ubiquitous in nature, but constraints imposed by specialization may limit their ability to colonize novel environments synchronously. The ability of mutualisms to reassemble following disturbance is central to understanding their response to global change. Here, we demonstrate that a highly specialized pollination mutualism considered to be obligate (Phyllanthaceae: Glochidion; L...

Four new Epicephala species that feed on the seeds of Glochidionsphaerogynum (Phyllanthaceae) from Yinggeling Mountain Nature Reserves in Hainan Province of China are described: Epicephaladomina sp. n., Epicephalaimpolliniferens sp. n., Epicephalaangustisaccula sp. n. and Epicephalacamurella sp. n. The latter two species are also associated with Glochidionwrightii. Photographs of adults and gen...

Revision of the Japanese species of Epicephala Meyrick with descriptions of seven new species (Lepidoptera, Gracillariidae)

Epicephala moths are involved in obligate mutualisms with their Phyllanthaceae hosts, in which the female moths assure pollination and, in return, their progeny develop by consuming the seeds. Ecological, molecular and geographical data suggest that the genus includes several hundred species, but the majority remains to be formally described. Here we revise the Japanese species of Epicephala Me...
