New Guinea is one of the centres of diversity of Benstonea (Pandanaceae), a genus distributed from India to Fiji. Ten species were previously recognised on this island and further field observations, accompanied by the study of available herbarium material have brought new insights into species delimitations within a group of caespitose species with a solitary terminal infructescence. The taxonomical identity of Benstonea odoardoi is elucidated and is considered here as a synonym of Benstonea lauterbachii. Three new combinations and a new name—based on names of Pandanus species previously treated as synonyms of Benstonea odoardoi—are proposed for four distinct species belonging to this group of caespitose species and restricted to Indonesian New Guinea and Papua New Guinea. Finally, Pandanus bintuniensis is here considered as a synonym of Benstonea permicron.

Benstonea (Pandanaceae) was circumscribed to include 57 species formerly placed in the genus Pandanus. Field observations, accompanied by the study of available herbarium material have brought new insights for the delimitation of certain problematic species, especially in the difficult group of species characterized by an axillary infructescence on a short peduncle covered by prophylls and the abscission of the basal portion of the drupe at maturity. New combinations, based on names in Pandanus previously treated as synonyms of Benstonea stenocarpa, are proposed for three distinct species of this group from Halmahera (Indonesia) and Papua New Guinea. The identity of Benstonea celebica, endemic to Sulawesi (Indonesia), is also elucidated and an epitype is designated for this species.

On This Island

Material collected between 1999 and 2011 in Papua New Guinea and the Papua Province of Indonesia unveiled the enormous diversity ofLabiobaetison this island. Twenty-six new species were identified and delimited by integrative taxonomy using genetic distance (COI, Kimura-2-parameter) and morphology. These new species are described and illustrated based on larvae, augmenting the total number ofLabiobaetisspecies on the island of New Guinea to 32. Seven morpho-groups of species are proposed based on morphological characters and a key to all New Guinea species is provided. The generic attributes of the larvae are summarised and slightly modified based on the examinations of the new species. Results on the genetics of most species (COI) are also provided. The interspecific K2P distances are between 13% and 32%, the intraspecific distances usually between 0% and 2%. Possible reasons for the remarkable richness of this genus in New Guinea are discussed.

Australasian Region

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.

Three New Species

AbstractComposition, systematics, distribution and bionomics of the poorly known primarily Oriental genus Anchocerus Fauvel, 1905 is reviewed, with an annotated list and identification key provided for all 13 named species of the genus. The poorly known species from Papua New Guinea, A. punctus Last, 1980, A. similis Last, 1980 and A. wilhelmensis Last, 1980 are redescribed. Three new species, A. aparamerus sp.n. from Borneo, A. grandis sp.n. and A. thailandicus sp.n., both from Thailand are described. One species is transferred to Anchocerus from the genus Acylophorus Nordmann, 1837: Anchocerus tenuipes (Lea, 1929) comb. n., and also redescribed. Two species of Anchocerus are moved to Acylophorus: Acylophorus novaguinensis (Last, 1975) comb. n. and Acylophorus okasaensis (Last, 1975) comb. n. Morphological characters distinguishing the genera Anchocerus and Acylophorus are summarized. Type material was examined for all insufficiently known species.

Our research team worked with Nakanai land-holders in Papua New Guinea to perform the first survey of butterflies in the Lake Hargy caldera of West New Britain Province. Methods included modified Pollard transects quantifying sampling effort based on aerial netting and visual observations, as well as traps baited with fermenting fruit. Results were compared with surveys on the adjacent Hargy Oil Palm plantation. Our sampling yielded 312 specimens representing 73 species; of these, 50 were limited to primary rainforest, 12 to oil palm plantation and 11 species occurred at both sites. Four species are newly recorded for New Britain, including one potentially invasive species on Citrus. Singleton specimens made up the largest abundance class in the data set, representing 34% of records in primary rainforest. Sixty-two percent of the butterfly taxa recorded are regionally endemic to the Bismarck island chain or to New Britain in particular. Calculated levels of similarity between sites ranged from 0.151 to 0.262, suggesting the oil palm and rainforest habitats supported highly distinct species assemblages. Although rapid assessment data such as these are necessarily limited in scope, they can still aid in documenting the impact on biodiversity from conversion of primary tropical rainforest to oil palm monoculture.
