Keywords: Ancyronyx; Spider Water Beetles; Elmidae; distribution; record; new species; larva; Mindoro; Philippines

Project details

Project title: Survey and Evaluation of Rural Landscape Biodiversity of Roxas, Oriental Mindoro, with Identification and Scientific Description of Taxa New to Science, Identification of Priority Areas for Conservation
Personnel: Hendrik Freitag
Funding: Commission on Higher Education (Philippines), PHERNet program; Ateneo de Manila University Loyola Schools Scholarly Work Grant
Study area descriptions/descriptor: Main focus: Baroc River Catchment, San Vicente, Roxas, Oriental Mindoro, Philippines

Design description: The Baroc River Catchment Survey of the Ateneo de Manila University focuses on the Key Biodiversity Area “Hinunduang Mt.”, classified as a terrestrial and inland water area of very high biological importance and extremely high critical conservation priority, under high socioeconomic pressure, which is, however, only subjected to moderate conservation efforts and not yet formally protected. Recent project collections and previously collected specimens from Mindoro were included in the study. They are partly from other conservation and research priority areas of high and highest urgency (“Naujan Lake National Park” and “Puerto Galera.”).

Natural collections description

Parent collection identifier: several
Collection name: several
Collection identifier: see acronym
Specimen preservation method: Pinned
Curatorial unit: 350 with an uncertainty of 100 (specimens (larvae and adults))

Methods

Method step description: The material was preserved in 95% ethyl alcohol to allow genetic sequencing. Most material was retrieved during the ongoing Baroc River Catchment Survey. Material collections from the 1990s were examined at the Natural History Museum Vienna, Austria (NMW), the Senckenberg Museum für Tierkunde Dresden, Germany (SMTD), and the Zoological Museum of the University Copenhagen, Denmark (ZMUC).
Study extent description: The sampling of all study sites within the main area in focus (Baroc River Catchment, Roxas) was replicated for at least four times between 2011 and 2013, covering both, dry and rainy seasons. All other collection sites were surveyed once by different collectors, except for the Tamaraw Falls, Puerto Galera (one replicate).
Sampling description: All specimens were collected from submerged substrates by the use of a hand-net or manually gathered from coarse particulate organic matter. Letter codes in parenthesis refer to a particular sampling station and microhabitat of the Baroc River Catchment. Number codes are arbitrary.
