Aquatic Coleoptera of the Lake Manguao Catchment, Palawan, the Philippines

Abstract

Results of an inventory of the aquatic and paraaquatic beetle fauna (Insecta: Coleoptera) of small streams in a lake catchment of northern Palawan are presented. Thirty-two sample sites and the sampling methods used are described herein. A total of 56 species taxa were recorded, with the majority of the collected material determined to species level. References and information on ecology, distribution and collection sites are given for each identified taxon. Some taxa are recorded for the first time in the Philippines, and endemic and undescribed taxa are discussed. Additional environmental data of the sampled aquatic and the surrounding terrestrial habitats are provided and discussed in comparison with data of previous surveys in the area.
