A tiny new species of Spider Water Beetles has been discovered on the Philippine Island of Mindoro by researchers from Ateneo de Manila University. The new species is named Ancyronyx buhid. The above image above shows the larva and adult of the newly discovered Buhid Spider Water Beetle. The assignment of the immature larvae with the adult beetles was done by DNA tests. The beetle was also photographed under a scanning electron microscope.
