| dc.description | Kajian taksonomi dan filogeni telah dijalankan ke atas genus Xanthopimpla Saussure 1892 (Hymenoptera: Ichneumonidae: Pimplinae) dari Sundaland. Objektif kajian adalah menjalankan pengecaman ke atas genus Xanthopimpla hingga ke peringkat spesies, membina kekunci dikotomi, menperihal spesies lama disamping menyertakan pemerihalan lengkap bagi spesies baru serta mengkaji hubungan filogenetik dalam kalangan spesies Xanthopimpla dengan menggunakan spesimen yang terdapat di Pusat Sistematik Serangga (CIS) dan spesimen yang dipinjam dari Afdeling National Museum of Natural History Netherlands (ZMAN), Swedish Museum of Natural History (NRM), British Natural History Museum London (BMNH) dan Jabatan Pertanian Malaysia (DOA). Perihalan lengkap bagi 31 spesies Xanthopimpla telah dilakukan melalui penyertaan gambar rajah foto dan ilustrasi spesies. Tambahan pula, pohon filogeni telah dihasilkan menggunakan perisian PAUP*4.0 dan kaedah analisis Parsimoni Maksimum (MP) secara heuristik dengan replikasi 100. Data matriks yang merangkumi 83 ciri-ciri morfologi menghasilkan kladogram yang kurang terurai dan tersokong. Pohon filogeni membentuk kumpulan monofiletik sesama ahli dalam 'kumpulan dalam'. konflik timbul apabila kladogram terhasil dibandingkan dengan pengklasifikasian kumpulan genus Xanthopimpla oleh Townes & Chiu (1970). Kladogram menyokong pengklasifikasian X. melanacantha melanacantha dan X. corynoceros corynoceros ke dalam kumpulan genus Rhopaloceros oleh Townes & Chiu (1970) dengan nilai butstrap sebanyak 57%. Namun begitu, kladogram juga turut menentang Townes & Chiu (1970) yang mengkategorikan X. decurtata detruncata, X. polyspila dan X. flaviceps ke dalam kumpulan Terebatrix kerana spesies-spesies ini mencapah membentuk klad yang berbeza-beza. Oleh sebab itu, kajian yang lanjut harus dijalankan untuk mendapatkan maklumat genus Xanthopimpla yang lebih banyak dari serata dunia disebabkan kepentingannya sebagai agen kawalan biologi dan demi menjamin keseimbangan alam.,The taxonomic and phylogenetic studies of genus Xanthopimpla Saussure 1892 (Hymenoptera: Ichneumonidae: Pimplinae) from Sundaland were conducted. The objectives of this study were to identify Xanthopimpla to species level, to prepare the dichotomous key, to redescribe the present species, as well as to provide the complete description of new species and to determine the phylogenetic relationship of Xanthopimpla species. Specimens available in Centre for Insects Systematic (CIS) and loan specimens from Afdeling National Museum of Natural History Netherlands (ZMAN), Swedish Museum of Natural History (NRM), British Natural History Museum London (BMNH) and Department of Agricultural Malaysia (DOA) were examined for the particular objectives. Complete description of 31 Xanthopimpla species with photos and illustrations presented. In addition, a phylogeny tree was generated using PAUP*4.0 with Maximum Parsimony (MP) heuristic search and 100 replicates. A data matrix consists of 83 morphological characters yielded a less resolved and supported cladogram. The phylogeny tree show that Xanthopimpla formed monophyletic clade within ingroups. Conflict rise when the cladogram compared with species classification by Townes & Chiu (1970). The cladogram tends to defend classification of X. melanacantha melanacantha and X. corynoceros corynoceros into group of Rhopaloceros by Townes & Chiu (1970) with the bootstrap value 57%. In contrast, the phylogenetic tree opposes classification of X. decurtata detruncata, X. polyspila, and X. flaviceps into Terebatrix group by Townes & Chiu (1970) due to species divergence. Further studies should be conducted to gain more information about genus Xanthopimpla from all over the world as they are important as a keystone species and biological control agent.,Master | |
