Zaitzevia Nitida
''Zaitzevia'' is a genus of riffle beetles in the family Elmidae. There are about 19 described species in ''Zaitzevia''. The genus is named after the Russian entomologist Filipp Zaitsev ( ru). Taxonomy The genus ''Zaitzevia'' was originally described in 1923 by George Charles Champion, a British entomologist. Champion placed two species within the genus: ''Z. solidicornis'', which he designated as the type species, and ''Z. acutangula''. While ''Z. solidicornis'' remains the type species of the genus, ''Z. acutangula'' was later transferred to the genus '' Indosolus''. In 2001, American entomologist Harley Brown proposed dividing the genus into two subgenera in order to better represent the diversity of the genus. Subgenus ''Zaitzevia'' is represented by ''Z. solidicornis'', while the new subgenus ''Suzevia'' is represented by ''Z. posthonia.'' Species The following 21 species are recognized as belonging to the genus ''Zaitzevia'': Currently accepted * '' Zaitzevia ari ...

Elmidae
Elmidae, commonly known as riffle beetles, is a family of beetles in the superfamily Byrrhoidea described by John Curtis in 1830. Both adults and larvae are usually aquatic, living under rocks in fast-flowing shallow areas of streams, such as riffles, feeding on algae and biofilms. There are more than 150 genera and 1,500 described species in Elmidae. The oldest record of the group is '' Cretohypsilara'' from the Cenomanian aged Burmese amber Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. ....

Zaitzevia Thermae
''Zaitzevia thermae'', also called the warm springs zaitzevian riffle beetle, is a flightless, wingless small beetle found in aquatic habitats in Montana. Description The species is distinguished from other elmids by its 8–segmented antennae, its side–lying and silk like elytra, pimply abdominal sternum, and other minor genetic differences. In general, but not always, the more slender form of ''Z. thermae'' can visually differentiate it from its sister species, ''Z. parvula''. Taxonomy ''Zaitzevia thermae'' is sometimes treated as a synonym of or subspecies to '' Z. parvula''; though this appears to be because a morphology report by Hooter in 1991 went unpublished and widely unread, which concluded that ''Z. thermae'' was its own distinct species and not a subspecies of another member of the genus. Due to this and the fact that the species is appropriately listed by the US Fish and Wildlife Service, ''Z. thermae'' is generally considered its own unique species. Distrib ...
