Frugivorous dacine fruit flies were studied in a lowland tropical rain forest in Papua New Guinea to determine their host specificity, abundance, and the number of species attacking various plant species. Plant species hosted 0–3 fruit fly species at median (1–3 quartile) densities of 1 (0–17) fruit flies per 100 fruits. Fruit flies were mostly specialized to a single plant family (83% species) and within each family to a single genus (88% species), while most of the species (66%) were able to feed on >1 congeneric plant species. Only 30 from the 53 studied plant species were colonized by fruit flies. The plant–fruit fly food web, including these 30 plant species and the total of 29 fruit fly species feeding on them, was divided into 14 compartments, each including 1–8 plant species hosting mutually disjunct assemblages of fruit flies. This structure minimizes indirect interactions among plant species via shared herbivores. The local species pool was estimated at 152±32 (±SE) fruit fly species. Forty per cent of all taxonomically described species known from Papua New Guinea were reared or trapped in our study area. Such a high proportion indicates low beta-diversity of fruit flies. Steiner traps were highly efficient in sampling the lure-responsive fruit fly species as they re-collected 84% of all species trapped in the same area 5 y before. Fruit fly monitoring by these traps is a cheap, simple and efficient method for the study of spatial and temporal changes in rain-forest communities.

The Australian Tortricini, Schoenotenini, and Chlidanotini together include 40 species in 17 genera. The Tortricini which are represented by 16 species in six genera, fall into two groups, the Phricanthes group with two genera and the Eboda group with four genera. Phricanthes Meyr. contains four Australian species, P. peistica and P. diaphorus being described as new. The other two species have a wide distribution abroad. The larvae attack plants in the family Dilleniaceae. The endemic genus Scolioplecta Meyr. includes seven widely scattered species, of which S. exochus and S. allocotus are described as new. A new species, A. diapella, from the Cape York Peninsula is referred to Amboyna Razowski, based on an Indonesian species. Anameristes, gen. nov. is a monotypic genus from north Queensland rain forest, established for Eboda cyclopleura Turn. Eboda Walk, contains one Australian species, and a series of others in the Indo- Malayan and Papuan areas. Asterolepis Razowski includes three species from Australia and New Guinea, with A. earina from Cape York and A. brandti from Papua described as new. The Schoenotenini are represented by 19 Australian species in seven genera. Two elements are distinguished. The Proselena group ranges from India to the New Hebrides and Rapa, including eastern Australia and New Zealand, while the Schoenotenes group has reached its greatest diversity in New Guinea. Proselena Meyr, has two species; Syncratus, gen. nov. has two new species, S. scepanus and S. paroecus; Tracholena, gen, nov., with type species Cnephasia sulfurosa Meyr., has three species; and Palaeotoma Meyr. is monotypic. The larvae of Proselena are leaf miners in Bursaria, those of T. sulfurosa tunnel in the bark of exotic Cupressus, while Palaeotoma has larvae boring in insect galls on Eucalyptus. Larval characters of these are discussed and compared with those of the New Zealand Prothelymna and Dipterina. The wide-ranging Diactenis Meyr., with a single new Australian species D. tryphera, may also belong to this group. Two genera of the Schoenotenes group are known from Australia. Cornuticlava Diak. includes three rain forest species in northern Queensland, including C. aritrana and C. phanera described as new. Epitrichosma Low. contains seven Australian species, one of which comes from the Darwin area, another E. hesperia, sp. nov. from south-western Australia, one from rain forest in southern Queensland and eastern New South Wales, and four including two new species E. ceramina and E. metreta from north-eastern Queensland. The last also occurs in New Guinea. The Chlidanotini contain five Australian species in four genera. Trymalitis Meyr. and Caenognosis Wals. are small but widely distributed Old World genera. The two new monotypic endemic genera Daulocnema, based on D. epicharis, sp. nov., and Leurogyia, based on L. peristictum, sp. nov., are described. The venation, genitalia, mouth-parts, and other adult structures, used to distinguish the genera, together with the larval characters of a few species, are discussed and figured. The genitalia of both sexes and the wings of the Australian species are figured and keys to the genera and species are given.

Host Trees

ABSTRACTEight species of Myzolecanium Beccari (Hemiptera: Homoptera: Coccoidea: Coccidae) are reported from ant nests in stem cavities of living lowland rain forest trees in Papua New Guinea. The coccids are confined to this microhabitat but are associated with a taxonomically broad range of ants and host trees. Attendant ants belonged to six species in three genera and two subfamilies: Anonychomyrma Donisthorpe (Dolichoderinae), Crematogaster Lund (Myrmicinae) and Podomyrma F. Smith (Myrmicinae). Host plants belonged to at least five families and included both apparently specialized (with domatia) and unspecialized species. Saplings containing the nests of Anonychomyrma scrutator (F. Smith), Anonychomyrma sp. 1 and Podomyrma laevifrons F. Smith were dissected and the structure of nest chambers and their contents recorded. Only some chambers had entrance holes, but many were interconnected by transverse passages. The coccids were in low numbers and fairly evenly distributed between ant-occupied chambers. The characteristics of the Myzolecanium-ant association, the role of the coccids as trophobionts, and the nature of the plant associations are discussed. Taxonomically, new combinations are proposed by P. J. Gullan for three species previously placed in Cryptostigma Ferris: Myzolecanium endoeucalyptus (Qin & Gullan), M. magnetinsulae (Qin & Gullan), and M. robertsi (Williams & Watson).
