Coelostoma (Coelostoma) vitalisi, is a species of water scavenger beetle found in China, Taiwan, Japan, India, Indonesia, Japan, Malaysia, Nepal, Singapore, Sri Lanka, Cambodia, Thailand and Vietnam. [1] [2] [3] [4] [5]
Body length is about 4.1 to 4.7 mm. Body oval, and strongly convex. Dorsum blackish whereas labrum black with yellow edges. Elytral surface densely punctate, and sutural stria reaching basal half of elytra. Mesofemora consist with sparse strong setae. Abdominal ventrite V without stout setae. In male, aedeagus has widely angulate apex, large and wide gonopore and parameres bent inwards, with a tuft of setae at the apex. [6] There is a very wide median lobe with a very large subapical gonopore in aedeagus. [7]
Hydrophilidae, also known colloquially as water scavenger beetles, is a family of chiefly aquatic 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. Some of these formerly-included groups are primarily terrestrial or semi-aquatic.
Hydrophilus is a genus of beetles in the family Hydrophilidae, the water scavenger beetles. There are 50 species in three subgenera in the genus: Hydrophilus, Dibolocelus, and Temnopterus.
Hydrophilinae is the largest subfamily of Hydrophilidae that contains 1852 species in 61 genera and 8 tribes.
Berosus is a genus of beetles in the family Hydrophilidae, the water scavenger beetles. The genus contains 273 species. It is distributed worldwide.
Tropisternus is a genus of hydrophilid beetles with 63 species in five subgenera in North and South America.
Helochares is a genus of hydrophilid beetles with over 180 species in five subgenera worldwide.
Hydrochara is a genus of hydrophilid beetles with 23 species in North America, Europe, Asia, and Africa.
Helobata is a genus of hydrophilid beetles with 11 species in North and South America.
Hydrobiusini is a tribe in the subfamily Hydrophilinae of aquatic beetles, and containing 47 species in 9 genera.
Cymbiodyta is a genus of hydrophilid beetles with 31 species. Twenty–eight of the species occur in the Americas and three species in the Palearctic.
Hydrobiomorpha is a genus of water scavenger beetles in the family Hydrophilidae. There are 56 extant described species in Hydrobiomorpha, along with several fossil species.
Lycaste is a genus of leaf beetles in the subfamily Eumolpinae. It is known from South America. Callicolaspis was formerly considered a synonym of the genus, but in 2003 Callicolaspis was restored as a separate genus.
Horelophus walkeri is a small water scavenger beetle that is endemic to New Zealand.
Epimetopidae is a family of semi-aquatic beetles found on the edges of streams and shallow freshwater ponds. These beetles are shorter than half a centimeter long and have a pronotum with a central projection forming a shelf above the head. On the underside of the abdomen only four sternites are visible. There are less than a hundred species in three genera, Epimetopus which is restricted to the New World, mostly Neotropical, Eupotemus with two Afrotropical species and Eumetopus with some Oriental species. Females carry their eggcases on the underside of the abdomen.
Coelostoma is a genus of beetles belonging to the family Hydrophilidae. The genus was first described by Brullé in 1835. The genus has cosmopolitan distribution, with 111 described species, representing one of the most diverse genera of Hydrophilidae.
Brownephilus is a genus of water scavenger beetles in the family Hydrophilidae containing two described species. Brownephilus was formerly a subgenus of Hydrobiomorpha and was elevated to genus by Andrew E.Z. Short in 2010.
Protistolophus spangleri is a species of water scavenger beetles in the family Hydrophilidae and the only species in the genus Protistolophus. Protistolophus spangleri was described as a new species and genus by Andrew E.Z. Short in 2010. The species is known only from Venezuela.
Cercyon (Paracycreon) subsolanus, is a species of water scavenger beetle found in Bhutan, China, India, Indonesia, Malaysia, Nepal, Philippines, Singapore, Sri Lanka, Thailand, and Vietnam.
Chasmogenus abnormalis, is a species of water scavenger beetle found in Cambodia, Sri Lanka, Taiwan, Thailand, Vietnam, Ryukyu Islands and Indonesia: Borneo, Java, Sulawesi, Sumatra.
Coelostoma (Holocoelostoma) stultum, is a species of water scavenger beetle widely distributed in Palearctic and Oriental realms from West Pacific towards Indian Ocean, such as China, Taiwan, Andaman Islands, Myanmar, India, Indonesia, Japan, Korea, Malaysia, Mascarene Islands, Nicobar Islands, Oman, Philippines, Saudi Arabia, South Korea, Sri Lanka, Thailand, United Arab Emirates, Oman, and Vietnam.
