Hygrobia is a genus of aquatic beetles native to Europe, North Africa, China and Australia. It is the only genus in the family Hygrobiidae, also known as the Paelobiidae. These are known commonly as squeak beetles or screech-beetles.
There are six known living species, with a highly disjunct distribution, and one extinct species, Hygrobia cretzschmari.
The body length ranges from 8.0 to 11.0 mm. Compound eyes are present, not divided into ventral and dorsal portions, strongly protruding. Labrum is short and transverse. The antennae are filiform, almost glabrous, with 11 segments.
Hygrobiidae is thought to be the sister group to a clade comprising Dytiscidae (diving beetles), Amphizoidae (trout stream beetles) and Aspidytidae (cliff beetles), based on DNA sequence data.
Regarding the relationships among the species of Hygrobia, a recent phylogenetic analysis suggested a sister group relationship between H. hermanni and a clade formed by the Australian species, with H. nigra sister to H. australasiae.
Hygrobiidae probably diverged from other Hydradephagan clades around the time of the initial breakup of Pangea. The split between today’s Palearctic and Australian clades occurred later, possibly in the middle Mesozoic, by dispersal events.
Hygrobia australasiae (Clark, 1862) - Australia
Hygrobia davidi Bedel, 1883 - Jiangxi, southeastern China
Hygrobia maculata Britton, 1981 - Australia
Hygrobia nigra (Clark, 1862) - Australia
Hygrobia wattsi Hendrich, 2001 - Australia
There has been a controversy associated with deciding which is the valid family name of squeak beetles: Hygrobiidae or Paelobiidae. Paelobiidae has priority over Hygrobiidae, but the latter name was until recently much more widely used.

Hygrobia hermanni the screech beetle is a species of beetle in family Hygrobiidae. It is found in the Palearctic (South Europe, West Europa, North Africa )
and is found in stagnant and muddy waters.It able to make a strident grating noise hence the name screech beetle.The sound is produced when the sharp edge of the 7th abdominal tergite is rubbed against a subapical median file on the elytral undersurface.Hyptis
