Abstract
The species within the Tribe Dacini from Papua New Guinea, Indonesian Papua (West Papua, Central Papua, Papua), associated islands and Bougainville are recorded. In all, 296 species are recorded including 65 new species described herein. The new species are treated under two genera, Bactrocera Macquart (eight subgenera) and Dacus Fabricius (three subgenera). The following new species are described and illustrated: Bactrocera (Bactrocera) atriscuta, B. (B.) bisianumu, B. (B.) bogiae, B. (B.) bubiae, B. (B.) bukaensis, B. (B.) caccabata, B. (B.) centraliae, B (B.) dysoxyli, B. (B.) expandosa, B. (B.) fumica, B. (B.) gabensiae, B. (B.) kaiauiae, B. (B.) kauiae, B. (B.) keravatiae, B. (B.) kokodiae, B. (B.) kunvawaensis, B. (B.) labubulu, B. (B.) laensis, B. (B.) manusiae, B. (B.) meraiensis, B. (B.) monostriata, B. (B.) neoabdonigella, B. (B.) neoaeroginosa, B. (B.) ohuiae, B. (B.) paraendiandrae, B. (B.) paraochracea, B. (B.) pometiae, B. (B.) raunsepnaensis, B. (B.) rounaensis, B (B.) rutilana, B. (B.) saramandiae, B. (B.) sari, B. (B.) sylvania, B. (B.) tikelingiae, B. (B.) trivirgulata, B. (B.) waidoriae, B. (B.) yayamiae, Bactrocera (Bulladacus) curiosa, Bactrocera (Calodacus) insolita, Bactrocera (Hemizeugodacus) neoaglaiae, B. (H.) wilhelmiae, Bactrocera (Neozeugodacus) leblanci, Bactrocera (Semicallantra) cerberae, B. (S.) malasaitiae, Bactrocera (Tetradacus) arbuscula, B. (T.) novotnyi, B. (T.) procera, Bactrocera (Zeugodacus) aiyurae, B. (Z.) anglimpiae, B. (Z.) bainingsiae, B. (Z.) madangiae, B. (Z.) magiae, B. (Z.) mitparingii, B. (Z.) oiyaripensis, B. (Z.) parasepikae, B. (Z.) rufoscutella, B. (Z.) xanthovelata, Dacus (Callantra) nigrolobus, D. (Mellesis) alatifuscatus, Dacus (Neodacus) asteriscus, D. (N.) bimaculosus, D. (N.) curvabilis, D. (N.) kreeriae, D. (N.) lalokiae and D. (N.) neosignatifrons. Females of B. (Bactrocera) daruensis Drew, B. (Bactrocera) nigella (Drew) and B. (Bactrocera) thistletoni Drew are described and a revised description of B. (Bactrocera) torresiae Huxham & Hancock is presented. Bactrocera (Bactrocera) denigrata (Drew) is withdrawn from synonymy with B. longicornis Macquart, and a full description of B. longicornis is presented from a study of the holotype and 27 newly collected specimens. New geographical distribution, host plant and male lure records are presented for some species. The major pest species that occur in the geographical region covered by this publication are reviewed and their biosecurity risks to other regional countries discussed. The land mass of Papua New Guinea and Indonesian Papua contains a richer fauna than any other from South-east Asia to the eastern Pacific, presumably resulting from speciation in the rich rainforest ecosystem. Differences of opinion on the status of some species in the Bactrocera dorsalis complex and on the supraspecific classification within the genus Bactrocera are evident in the literature. We have acknowledged and discussed these differences and, as authors, have presented conclusions based on our own research data.
