Biology Faculty Publications

The genus Agraphydrus RÉGIMBART , 1903 (Coleoptera: Hydrophilidae) of the Republic of the Philippines is taxonomically reviewed aided by COI mtDNA barcodes. Nine new species are described, all currently regarded as endemic to the Philippines: A. abrasus sp.n., A. ampullatus sp.n., A. batak sp.n., A. brevilobatus sp.n., A. occultus sp.n., A. palawanensis sp.n., A. pelingeni sp.n., A. tenuipalpis sp.n., and A. zetteli sp.n.

COI sequences and thorough morphological examination suggest that this and further species represent a group …


Diversity Of Trichoptera Emergence And Their Longitudinal Distribution Along Streams In Central Palawan, The Philippines, Hendrik Freitag, Wolfram Mey Jun 2020

Diversity Of Trichoptera Emergence And Their Longitudinal Distribution Along Streams In Central Palawan, The Philippines, Hendrik Freitag, Wolfram Mey

Biology Faculty Publications

Trichoptera emergences were cumulatively collected from two rivers in central Palawan over 11 months by use of specially modified emergence traps. The quantitative samples were identified at species level. Fifty morphospecies, of which fifteen have been recently newly described, are recognized. The highest species diversity was found in pristine headwater streams. Leptoceridae were most speciose with eleven Oecetis spp., four Leptocerus spp., two Adicella spp., and one species each of Tagalopsyche, Triaenodes, and Triplectides. Highest abundances were observed for Ecnomus cabayugani (Ecnomidae), Dipseudopsis digitata, and Hyalopsyche winkleri (Dipseudopsidae) which contributed alone 34% of the annual emergence. A mid-stream site where …

A Mega-Diverse Water Beetle Genus (Coleoptera: Hydraenidae: Hydraena Kugelann) Commonly Overlooked In Southeast Asia And Its Potential Use For Environmental Biomonitoring, Hendrik Freitag Jan 2014

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, …
