Abstract

A systematic study on the dragonflies deposited in three major reference collections in Sarawak, namely the UNIMAS Insect Reference Collection, Sarawak Museum and Sarawak Forestry Corporation was conducted from 1/12/2008 to 31/12/2008. A total of513 specimens comprising 58 species of Anisopterans were examined in this study. The family Libellulidae dominated other family in composition of species with 65.52% domination, followed by Aeshnidae (12.07%), Gomphidae (10.34%), Corduliidae (10.34%) and Chlorogomphidae (1.72%). The family Chlorogomphidae was represented by single species only. The family Libellulidae, represented by 329 specimens in the collection, could be assumed as the most commonly found family. Orthetrum sabina and Neurothemis fluctuans were the most common species, represented by 174 specimens (33.92%) and 65 specimens (12.67%) in the collection respectively. Most of the odonate specimens were collected from Kota Samarahan, Kuching and Matang. The best represented species was Neurothemis fluctuans which widely distributed in Sarawak. Systematics accounts and distribution maps of each species or genus examined are presented.
