FAMILY HYDROPHILIDAE
This rather large family comprises about 2400 described species. Around 400 species in 60 genera are reported from the Oriental realm ( Hansen, 1999). Adult and larval hydrophilids have very different habits; the former are phytophagous or saprophagous, while the latter are predacious. Most members of the subfamily Sphaeridiinae are strictly terrestrial (except for the aquatic genus Coelostoma ), living in decaying vegetable matter, dung, carrion, damp soil and ant or termite nests ( Hansen, 1999). Like the Dytiscidae , the aquatic hydrophilids inhabit all kinds of freshwater habitats. Most of the aquatic species are oval to globose, smooth and glabrous, often resembling Dytiscidae , from which they differ in having short and clubbed antennae and long maxillary palps. A ventral plastron, which communicates with a small subelytral air reservoir, is also present. When the beetle rises to the surface, it breaks the surface film using its specialised antennal club, allowing communication between atmosphere and plastron (Lawrence & Britton, 1991). The plastron is held by a fine, golden setation, or hydrofuge pubescence, which covers the major part of the beetle’s venter.
