The water beetle fauna of northern Negros Island has not been comprehensively studied. In this study, aquatic Coleoptera of northern Negros have been compiled from various collections. Specimens were sampled through manual sampling and light trap. Twenty-six (26) species were recorded including 21 which are Philippine endemics. Nine genera and three known species are recorded for the first time from Negros. Notes on distribution, ecology and identification are provided. Possible new species, future potential discoveries as well as current significance in terms of conservation are discussed.

We present the results of a faunistic inventory undertaken on aquatic Polyphaga beetles as part of a workshop organised by the BIO-PHIL project in Cambodia. Three small rivers and a pond in Kampong Speu Province were sampled in July 2018. Twenty-one taxa were collected during the sampling and identifi ed to species or morphospecies level. These are described with comments on habitat, distribution and further remarks, where applicable. A checklist of the genera and species of aquatic Dryopidae, Elmidae, Hydraenidae, Hydrophilidae, Psephenidae and Spercheidae of Cambodia is presented which includes new records for the country
A Mega-Diverse Water Beetle Genus (Coleoptera: Hydraenidae: Hydraena Kugelann) Commonly Overlooked In Southeast Asia And Its Potential Use For Environmental Biomonitoring, Hendrik Freitag
Biology Faculty Publications
This study summarizes the current knowledge of the water beetle genus Hydraena Kugelann in Southeast Asia. The surprising species diversity and endemism rates in Hydraenopsis Janssens, the only subgenus present in Southeast Asia, are discussed. Data of five published Hydraena surveys from the Philippines and Singapore are used to evaluate species richness and the occurrence of species assemblages that are subject to the presence and quality of forests. Species richness was found to be generally higher in old grown forests. Some species appeared to be confined to near-natural forests. The denomination of indicator species is impeded by adequate sampling data, …
