They can be separated by the antennae, by the mandibular palps (if long), by lack of a notopleural suture on the prothorax, and by the possession of moveable as opposed to fixed hind coxae.

 Hydrophiloidea
Hydrophilidae is frequently divided into as many as 6 families (e.g.
Like Hydrophilidae, Sphaeritidae is known to be saprophagous in the adult stage (Nikitsky, 1976; Löbl, 1996; Newton, 2001), while Synteliidae and Histeridae have become primarily predaceous in all life stages (Mamayev, 1974; Newton, 1991).
The sister group relationship between Synteliidae and Histeridae is also supported by several morphological characters including concealment of the protrochanters (adults), sclerotization of the abdominal tergites from at least tergite 4 and back, and loss of the cardo of the larval maxilla (Ohara, 1995; Hansen, 1997; Slipinski and Mazur, 1999).

Hydrophilidae beetles are characterized by the 4 segment club on the end of their beadlike antennae.
The body is oval or elliptical, convex on the dorsal side and flat on the ventral side.
In fact, it is one of the first water scavenger beetles found in newly formed pools, such as those formed in rainbuckets or wheelbarrows.

Hydrophilidae are characterized by having relatively short antennae consisting of 7 or 9 segments and a distinct pubescent club of 3 or rarely 4 segments, preceded by a transverse, glabrous segment called the cupule (fourth figure).
The smaller, terrestrial species of Hydrophilidae (last three figures) are often misidentified as members of several other families characterized by having small, shiny, dark, round to ovate adults.
One should note the short antennae and long palps, often combined with a dull, finely pubescent undersurface (plastron).

Larval characters that define the ancestor of Polyphagaare few, but several of those characters have been modified in at least some hydrophiloids, most of these modifications are correlated with their aquatic and predatory habits.
Among the characters of interest are: a-modification of the abdominal segments eight to ten due to the development of a respiratory atrium; apparently this occurs once in the ancestor of Hydrochidae, Spercheidae and Hydrophilidae.

Dytiscids have well developed hair fringes on their tibiae and tarsi and have a streamlined shape.
They are superficially similar to the Hydrophilidae, but may be distinguished from that family by their well developed, and easily seen antennae.
Also, Dytiscidae and Hydrophilidae usually differ in profile with dytiscids tending to have a more equally convex dorsum and sternum while hydrophilids are usually much more convex dorsally than ventrally.

 Review of the aquatic Hydrophilidae (Coleoptera) of Costa Rica   (Site not responding. Last check: 2007-11-04)
Andrew Edward Z. Short, Department of Entomology, Cornell University, Department of Entomology, 2144C Comstock Hall, Ithaca, NY Representing one of the most specious groups of aquatic beetles in Central America, the Hydrophilinae (Coleoptera: Hydrophilidae) are found in virtually every aquatic habitat including ponds, streams, waterfalls, and at the base of water-collecting plants such as bromeliads.
The collection of the Instituto Nacional de Biodiversidad (INBio), containing approximately 25,000 specimens of Hydrophilidae, was examined and supplemented by collecting efforts in January and June of 2003.
While only 24 species are currently recorded as occurring in Costa Rica, more than 60 species were found, with approximately 20% being undescribed.

Unlike beetle larvae of the Elmidae family, organisms of the Hydrophilidae family are rarely found in the River because they have a short larval cycle (one to several months).
They are the larval form of adult water scavenger beetles and like the adults, the larvae feed on other insects.
They are generally found in areas where sediment has been deposited along the banks.
