Sternolophus rufipes is a species of water scavenger beetle found in India, Sri Lanka, China, South Korea and the Philippines. [1] [2] [3] [4] [5]
This large oval species has a body size of about 10.2 mm. Elytra with four distinct rows of systematic punctures. Antennae with nine segments. Prosternum highly tectiform and carinate medially. Metasternal keel glabrous and produced into a short spine posteriorly and passed to the first ventrite. On the base of middle and hind femora, there is a hydrofuge pubescence as well as in abdominal ventrites. Mesosternal keel has a small notch and long apical setae. Posterior margin of fifth ventrite is rounded. [6] [7]
Hydrophilidae, also known colloquially as water scavenger beetles, is a family of beetles. Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae. Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae, Helophoridae, Hydrochidae, and Spercheidae. While the majority of hydrophilids are aquatic, around a third of described species are terrestrial, mostly belonging to the subfamily Sphaeridiinae.
Hydrophiloidea, known as water scavenger beetles, is a superfamily of beetles. Until recently it included only a single family, the Hydrophilidae, but several of the subfamilies have been removed and raised to family rank. Hydrophiliidae remains by far the largest member of the group, with nearly 3,000 described species. The other families have no more than 400 species. The Histeroidea are closely related and sometimes considered part of a sensu lato Hydrophiloidea. The majority of the clade is aquatic, which is thought to be the ancestral ecology of the group, with some lineages like Sphaeridiinae becoming secondarily terrestrial. Modern representatives of the group first appeared during the Late Jurassic.
