Resumen:
Several evolutionary trends of sphaeridiine beetles are discussed: terrestrial habits,larval developmental time, number of eggslegg case, shape of the egg cases, prey consumption,construction of pupal chambers, reduction of the legs, development of hypopharyngeallobes, symmetry of mandibles and labroclypeus, reduction of the ligula andfusion of stemmata. A discussion on the state of knowledge of the immature stages ofHydrophilidae at a generic level is presented; of the four most diverse zoogeographicareas, the Oriental, Australian and Ethiopian are the less known and the Neotropical isrelatively well known; the Palaearctic and Nearctic are the least diverse but the bestknown.
