Ficus sect. adenosperma

The structure, distribution and classification of the twenty species of sect Adenosperma are reviewed. The section is centred on New Guinea where nineteen species occur and F. megalophylla persists as the pachycaul relic. The section relates with sect. Sycocarpus subsect. Auriculisperma of the Solomon Islands and connects with the origin of sect. Ficus through the Philippine species F. pseudopalma and F. rivularis along the Sararanga -front of the Melanesian Foreland. The most widespread species are among the most advanced. They show the usual trend in Ficusfrom the stout pachycaul with large multibracteate fig to the leptocaul with lanceolate leaf and small fig, along with the development of cauliflory and geocarpy. There is no evidence to suggest that the species evolved through vicariism, and the two series Amphigenae and Hypogenae run almost identical courses from Celebes to New Hebrides. Two new species are described from New Guinea, F. pilulifera and F. suffruticosa.

The taxonomy and distribution of Pacific Annonaceae are reviewed in light of recent changes in generic delimitations. A new species of the genus Monoon from the Solomon Archipelago is described, Monoon salomonicum I.M.Turner & Utteridge sp. nov., together with an apparently related new species from New Guinea, Monoon pachypetalum I.M.Turner & Utteridge sp. nov. The confirmed presence of the genus in the Solomon Islands extends the generic range eastward beyond New Guinea. Two new species of Huberantha are described, Huberantha asymmetrica I.M.Turner & Utteridge sp. nov. and Huberantha whistleri I.M.Turner & Utteridge sp. nov., from the Solomon Islands and Samoa respectively. New combinations are proposed: Drepananthus novoguineensis (Baker f.) I.M.Turner & Utteridge comb. nov., Meiogyne punctulata (Baill.) I.M.Turner & Utteridge comb. nov. and Monoon merrillii (Kaneh.) I.M.Turner & Utteridge comb. nov. One neotype and four lectotypes are designated. The geographic patterns exhibited by nine native Annonaceae genera, that range in the Pacific beyond New Guinea, are discussed.


The biogeography of the subgenus is correlated with the morphological evolution of the species. From a source round the Coral Sea the subgenus has diversified into four evolutionary lines, namely sect. Pharmacosycea (America), ser. Nervosae (Indo-Pacific), ser. Vasculosae (Afro-Indo-Pacific) and ser. Austrocaledonicae (New Caledonia, Loyalty Islands, New Hebrides). The last in its isolation shows the pachycaul-leptocaul evolution. F. pseudojaca (New Guinea) is critical in this interpretation. F. smithii is removed to ser. Nervosae. F. pritchardii (Fiji) is removed to sect. Sycocarpus subsect. Papuasyce in alliance with F. microdictya , but this group may relate with ancestral Pharmacosycea . The species of ser. Austrocaledonicae are described and illustrated to show this unique evolutionary line: F. lifouensis (Loyalty Isl.) is described as new. In ser. Nervosae , in the alliance of F. pachysycia , two new species are described, F. homodroma and F. mesotes .

Tokunagahelea is proposed as a new subgenus of the genus Culicoides Latreille to embrace three species from New Guinea and the Solomon Islands. Comparative descriptions of both males and females of Culicoides mikros, sp. nov., and C. geocheloneoides, sp. nov., and a redescription of the female of C. pygmaeus Tokunaga (male unknown), are presented together with a key for differentiation. C. mikros is the designated type species of the subgenus. Systematic relationships of the new subgenus are discussed.

SummaryIn view of the discovery of several new species and subspecies of Amblypelta (Hemiptera, COREIDAE), some of which are either known to be or else threaten to become of economic importance, a revision of the whole genus has become necessary.The genus Amblypelta, as defined in the present paper and as known so far, is confined to Australia north of Sydney, the islands between Australia and New Guinea, New Guinea and, to the west, the Kai Is., Timor and Java; the Bismarck Archipelago, the Solomon Islands including Bougainville, Eennell and Bellona; the New Hebrides and New Caledonia. In the present revision of the genus, twelve species and five subspecies are included, of which all but seven species are new to science. Apart from the descriptions of the new species and subspecies, taxonomic notes on the previously known species are given as well as a key to all the species.The known distribution of each species is stated, and consideration given to the zoogeography of the genus as a whole, and of certain species-groups which can be recognised within the genus.

KIEW, R. 2015. Chionanthus (Oleaceae) in Sulawesi, Indonesia, including three new species. Reinwardtia 14(2): 287 - 295. - The genus Chionanthus (Oleaceae) in Sulawesi is revised. Nine species are described of which C. kostermansii Kiew, C. sordidus Kiew and C. sulawesicus Kiew are new species. Four species are endemic, C. celebicus Koord., C. sordidus, C. stenurus (Merr.) Kiew and C. sulawesicus. The geographic range of C. cordulatus Koord. extends to Borneo and Mollucas, while C. kostermansii also occurs in Sumbawa and Flores, and the range of C. rupicolus (Lingelsh.) Kiew extends to Sumbawa, Mollucas, New Guinea and the Bismarck Archipelago. Chionanthus polygamus (Roxb.) Kiew and C. ramiflorus Roxb. are both widespread species, the former from Sumatra to New Guinea and the latter from continental Asia to the Solomon Islands. A key to identify the species is provided. Chionanthus gigantifolius Koord. remains incompletely known.

AbstractThe Aschistodesmini from the Solomon Island are reviewed. Besides clarifying notes on the status of the type and closely related species of Aschistodesmus, descriptive notes and illustrations of the gonopods of the Solomon species of this genus, particularly of those published by Chamberlin, 1920, under the generic name of Solomonosoma, are given. Two new species, A. spatulifer and A. tridentifer are described, and a key to the species is provided. From Rennell Island Dorcadogonus modestus gen. n., sp. n. is described.

The biosystematic position of the Parallelia generic complex is reviewed and a revised generic classification of its component taxa is presented. Bastilla Swinhoe (= Xiana Nye, syn. nov., Naxia Guenée, syn. nov.) is identified as the most appropriate genus for a large number of these taxa, including the joviana-group, which is reviewed in detail, with description of two new species, B. nielseni, sp. nov. and B. binatang, sp. nov. Parallelia prouti Hulstaert, syn. nov. and P. cuneifascia Hulstaert, syn. nov. are recognised as junior synonyms of Bastilla vitiensis Butler and two newly described Tahitian taxa are transferred into the joviana-group. Larval host records are examined in relation to this new generic system and significant preference for the Euphorbiaceae is noted for several groups: Bastilla, Buzara Walker (= Caranilla Moore, syn. nov., another segregate from Parallelia) and an Australian group within Grammodes Guenée.
