Latest version published by ZooKeys on Aug 30, 2013 ZooKeys

Seven species of Hydraenidae, Hydrophilidae and Elmidae are recorded from temporary freshwater habitats at the Ateneo de Manila University Campus in the metropolitan area of Manila, Philippines. They were identified as Enochrus (Lumetus) fragiloides d’Orchymont, Helochares (Hydrobaticus) lepidus d’Orchymont, Helochares (Helochares) pallens (MacLeay), Stenelmis sp.1, Hydraena (Hydraenopsis) scabra d’Orchymont, Hydraena (Hydraenopsis) palawanensis Freitag & Jäch, and the recently describen Hydraena (Hydraenopsis) ateneo Freitag.

Sampling Methods

Bottom substrates were physically disturbed in a way that drifted arthropods could be collected by the use of a fine-meshed hand net. Additionally, submerged coarse particulate organic matter, mainly leaves, were manually taken off from the water and checked for benthic organisms.

Study Extent Three permanently water-filled ponds, five temporary rock pools and three temporary creeks, most of them in small forest-like patches of secondary vegetation, were sampled for aquatic insects. All of them contained at least some water for most of the time of the year except for a few months (January to May) in the dry season. The first survey was done at the beginning of the dry season in November 2012 when the water bodies were still filled with water. A replicate sampling was performed in June 2013, the second month of the wet season.
Step Description 1 The material was initially preserved in 95% ethyl alcohol. All type material designated herein and other dissected voucher specimens were glued on entomological paper and pinned. Specimens were examined with the help of an OLYMPUS SZ 61 stereo microscope. Dissected body parts were examinded in lactic acid under an OLYMPUS CX21 compound microscope.
