The new genus Hortophora in the orb-weaving spider family Araneidae Clerck, 1757 is established to include 13 species from the Australasian-Pacific region, with ten species known from Australia (five of which new to science): Hortophora biapicata (L. Koch, 1871), comb. nov. (type species) (= Araneus biapicatifera Strand, 1907, syn. nov.; = Epeira frosti Hogg, 1896, syn. nov.); H. cucullussp. nov.; H. lodicula (Keyserling, 1887), comb. nov. (= Epeira scutigerens Hogg, 1900, syn. nov.); H. megacanthasp. nov.; H. porongurupsp. nov.; H. tatianeaesp. nov.; H. transmarina (Keyserling, 1865), comb. nov.) (also known from Papua New Guinea); H. urbana (Keyserling, 1887), comb. nov.; H. walesiana (Karsch, 1878), comb. nov. (= Epeira rhombocephalaThorell 1881, syn. nov.; = Epeira lutulenta Keyserling, 1886, syn. nov.); and H. yesabahsp. nov. The following species of Hortophoragen. nov. are recognised from the Pacific region but not revised in detail due to a lack of material, specifically mature males: Hortophora capitalis (L. Koch, 1871), comb. nov. (removed from synonymy with H. transmarinacomb. nov.) from Fiji, New Caledonia and Vanuatu; H. flavicoma (Simon, 1880), comb. nov. from New Caledonia (incl. Loyalty Islands) and H. viridis (Keyserling, 1865), comb. nov. (removed from synonymy with H. transmarinacomb. nov.) from Samoa. Epeira thyridota Thorell, 1870 is here removed from synonymy with H. transmarinacomb. nov. and transferred to Backobourkia Framenau, Dupérré, Blackledge & Vink, 2010, B. thyridota (Thorell, 1870), comb. nov.Hortophoragen. nov. includes medium-sized to large, nocturnal orb-weaving spiders typically with subtriangular to ovoid abdomen bearing humeral humps. The tibiae of the second leg in males is usually enlarged with numerous strong spines and an apico-ventral megaspur carrying a large spine in some species. Male pedipalps generally have an elongated, transverse median apophysis ending in a bifid tip in most species, a sinuous to straight embolus and a bubble-shaped terminal apophysis. The female epigyne scape is highly elongated and does not have a terminal pocket. Genital mutilation, i.e. breaking off the epigyne scape during copulation, is common in some species. Hortophoragen. nov. include the most frequently collected nocturnal orb-weaving spiders in Australia.

A taxonomic revision of Didymochlaena (Didymochlaenaceae) from Asia and the Pacific region is conducted based on morphological and molecular evidence. Seven species are recognized, of which four are described as new and a new status is raised to a species from a variety. These four new species include D. fijiensis from Fiji, D. philippensis from the Philippines, D. punctata from Indonesia, Malaysia, and Thailand, and D. solomonensis from the Solomon Islands. The new status is D. oceanica from Papua New Guinea. Six of the seven species have all been erroneously treated as D. truncatula by earlier pteridologists. A key to the species is provided and descriptions of all species are given.

The genera of microgastrine braconid wasps present in the Australasian region (defined as Australia, New Zealand, New Caledonia, New Guinea, Solomon Is, Fiji Is, Samoan Is, Cook Is, but not French Polynesia) are reviewed. An illustrated key to genera, comments on their taxonomy, and information on the distribution and host relationships of species are provided. Following examination of holotypes, the generic placement of all species recorded from the region is reassessed since a recent generic reclassification of the subfamily left most of the Australasian species incorrectly placed. Parapanteles Ashmead (N.T.), Fornicia Brullé (Qld) and Deuterixys Mason (Qld) are recorded from Australasia for the first time, while Buluka De Seager, Parenion Nixon, Snellenius Westwood and Wilkinsonellus Mason, previously known from Australasia, are recorded from mainland Australia for the first time. The genus Austrocotesia is described as new [with A. exigua, sp. nov. (Papua New Guinea) as the type species], along with the following 14 species: Austrocotesia delicata, sp. nov. (Papua New Guinea, Qld), A. paradoxa, sp. nov. (Papua New Guinea), Buluka collessi, sp. nov. (Qld), Deuterixys anica, sp. nov. (Vic., N.S. W., Qld), Fornicia commoni, sp. nov. (Qld), Glyptapanteles deliasa, sp. nov. (S.A.), Microgaster nixoni, sp. nov. (Tas., N.S.W.), Parapanteles masoni, sp. nov. (N.T.), Parenion beelaronga, sp. nov. (Qld), P. bootha, sp. nov. (Qld), Sathon albicoxa, sp. nov. (Tas., Vic., N.S.W.), S. naryciae, sp. nov. (Vic.), Wilkinsonellus amplus, sp. nov. (Qld, N.T.) and W. tomi, sp. nov. (Papua New Guinea, New Britain, Qld). Glyptapanteles guyanensis (Cameron), comb. nov. is excluded from the Australasian fauna; the name Glyptapanteles fullawayi, nom. nov. (Samoa) is proposed for Apanteles opercuiinae var. polita Fullaway; lectotypes are designated for Cotesia deliadis (Bingham), comb. nov. (Qld), C. philoeampa (Cameron), comb. nov. (N.S.W) and C. rufiventris (Bingham), comb. nov. (Qld); Glyptapanteles operculinae (Fullaway), comb. nov. (Samoa), Microgaster kuchingensis Wilkinson (Papua New Guinea) and Sathon moratus (Wilkinson), comb. nov. (Vic., S.A., W.A.) are redescribed; and 41 additional new combinations are proposed.

The scorpion-tailed orb-weaving spiders in the genus Arachnura Vinson, 1863 (Araneidae Clerck, 1757) are revised for Australia and New Zealand. Arachnura higginsii (L. Koch, 1872) only occurs in Australia and A. feredayi (L. Koch, 1872) only in New Zealand. A single female collected in south-eastern Queensland (Australia) is here tentatively identified as A. melanura Simon, 1867, but it is doubtful that this species has established in Australia. Two juveniles from northern Queensland do not conform to the diagnoses of any of the above species and are illustrated pending a more thorough revision of the genus in South-East Asia and the Pacific region. An unidentified female from Westport (New Zealand) does not conform to the diagnoses of A. feredayi and A. higginsii, but is not described due to its poor preservation status. Arachnura caudatella Roewer, 1942 (replacement name for Epeira caudata Bradley, 1876), originally described from Hall Sound (Papua New Guinea) and repeatedly catalogued for Australia, is considered a nomen dubium.

Paramedetera, gen. nov., is described on the basis of three species: P. papuensis, sp. nov., the type species from Papua New Guinea, P. sumatrensis, sp. nov., from the lowlands in West Sumatra, and P. orientalis (Hollis, 1964), comb. nov., from the highlands in West Sumatra. Paramedetera, gen. nov., is closely allied to Medetera, but is a more ancestral branch. It is phylogenetically situated between on one hand Corindia and Thrypticus and on the other hand Medetera and Dolichophorus.

KIEW, R. 2020. Towards a Flora of New Guinea: Oleaceae. Part 1. Jasminum, Ligustrum, Myxopyrum and Olea. Reinwardtia 19(1): 1‒25. ‒‒ Oleaceae in New Guinea is represented by five genera and about 32 species, namely Chionanthus (about 16 species), Jasminum (10 species), Ligustrum (3 species), Myxopyrum (2 species) and Olea (1 species). A key to genera as well as descriptions of and keys to species of Jasminum, Ligustrum, Myxopyrum and Olea are provided. Of the three Ligustrum species, L. glomeratum is widespread throughout Malesia, L. novoguineense is endemic and L. parvifolium Kiew is a new endemic species. Six species of Jasminum are endemic (J. domatiigerum, J. gilgianum, J. magnificum, J. papuasicum, J. pipolyi and J. rupestre). Jasminum turneri just reaches the northern tip of Australia; of the two species from the Pacific Islands J. simplicifolium subsp. australiense just reaches SE Papua New Guinea and J. didymum, a coastal species, reaches into Malesia as far north as E Java; J. elongatum is widespread from Asia to Australia. Neither Myxopyrum species is endemic: M. nervosum subsp. nervosum extends from Peninsular Malaysia to Indonesian New Guinea, and M. ovatum from the Philippines to the Admiralty Islands. The sole species of Olea, O. paniculata, stretches from Java to Australia and New Caledonia.

Five new species of spiny solanums (Solanum subgenus Leptostemonum Bitter; the Leptostemonum Clade) are described from the islands of the Pacific. Two of the new species are from Fiji (S. pseudopedunculatum D.McClelland, sp. nov. and S. ratale D.McClelland, sp. nov.), two from New Caledonia (S. memoayanum D.McClelland, sp. nov. and S. semisucculentum D.McClelland, sp. nov.), one from Papua New Guinea (S. labyrinthinum D.McClelland, sp. nov.) and another from Vanuatu (S. vanuatuense D.McClelland, sp. nov.). A new status and combination is provided for the rare Hawaiian endemic S. caumii (F.Br.) D.McClelland, comb. et stat. nov. and a new type designated for S. peekelii Bitter of Papua New Guinea, for which a description is also provided. All species are illustrated with digitized herbarium specimens, mapped and have been assigned a preliminary conservation status using current IUCN guidelines. Details of all specimens examined are provided in a Suppl. materials 1: file SM1.

A revised classification of the Holothyridae is presented. The family is restricted to archipelagoes from Melanesia to the Seychelles, with no known records from any continent. Evolution of holothyrid characters, phylogenetic relationships of the eight holothyrid genera and criteria for taxonomic categories in Holothyridae are discussed.Holothyrus braueri Thon, 1905, from the Seychelle Islands, is selected as the type species of a new genus, Sternothyrus. A new genus, Lindothyrus, is created for L. rubellus, sp. nov., from the western coast of New Caledonia, and L. elongatus, sp. nov., from Lord Howe Island, Australia. Indothyrus greeni, gen. et sp. nov., is described from Sri Lanka. Hammenius (Leiothyrus) Hammen, 1983 is raised to generic rank and Holothyrus nitidissimus Thorell, 1882 from the Fly River, and H. armatus Canestrini from Tamara Island (Aitape), both New Guinea, are included in this genus. The two previously known New Guinean genera, Thonius Lehtinen, 1981 and Hammenius Lehtinen, 1981, are redefined and relimited, and their type species are redescribed. Five new holothyrid taxa are described from New Guinea: Thonius mendi from the Strickland River, T. berlesei from an unknown locality, Hammenius fujuge iora from the Central district, Oro Province, H. grandjeani gressitti from Mt Bosavi, and H. insularis from the Louisiade Archipelago. Holothyrus Gervais, 1842 is restricted to two species from Mauritius only. A new genus, Haplothyrus, is created for the New Caledonian species H. expolitissimus Berlese, 1924 and for H. hyatti, sp. nov., from an unknown locality. Haplothyrus is characterised by the possession of a single female genital valve instead of four valves, as in all other genera of this suborder. The poorly described Seychellian species with no preserved material could not be revised.

AbstractThe generic classification of water striders belonging to the veliid subfamily Haloveliinae is discussed and revised and a key to the genera provided. A new genus of marine haloveliines, Haloveloides gen. n., is described. The type species of the new genus, H. papuensis (Esaki) comb. n., is redescribed and recorded from Papua New Guinea, the Bismarck Archipelago, and the Solomons. H. browni (Lansbury) comb. n. is redescribed and recorded from the same areas as the type species. Five new species are described in the genus: H. brevicornis sp. n. (the Moluccas, Sulawesi, Palawan), sundaensis sp. n. (Sunda shelf areas), danpolhemi sp. n. (Palawan), cornuta sp. n. (Luzon), and femoralis sp. n. (Palawan). The cladistic relationships and biogeography of the species are discussed.

The genus Fennerogalathea Baba, 1988 was known to contain two species: F. chacei Baba, 1988, the type species, from the Philippines, Taiwan and Indonesia and F. chirostyloides Tirmizi & Javed, 1993 from the Bay of Bengal. In the present study, three new species of the genus are described and illustrated: F. chani n. sp. from Papua New Guinea, F. cultrata n. sp. from New Caledonia and Vanuatu and F. ensifera n. sp. from Fiji. The new species are morphologically distinguishable on the basis of the shape and spination of the rostrum and the presence/absence of a small spine on the frontal margin of the carapace. The species also show clear genetic differences (COI and 16S rDNA) among them.

Abstract Nediphya gen. n. and four new species, N. lehtineni sp. n. (type species), N. hippai sp. n., N. lyleae sp. n. and N. padillai sp. n. are described from Papua New Guinea. Some somatic characters of Nediphya gen. n. such as modified eyes and a prolateral row of stiff setae on legs I and II resemble those of Diphya Nicolet, 1849, but the morphology of its copulatory organs indicates it belongs to Nanometinae, a subfamily known only from Australasia. Th e status and composition of Nanometinae are briefly discussed. Nanometa gentilis Simon 1908 (the type species of Nanometa Simon, 1908), thought to be known only from the female, was actually described from both sexes.
