Proteobacteria is a major phylum of gram-negative bacteria. They include a wide variety of pathogens, such as Escherichia, Salmonella, Vibrio, Helicobacter, Yersinia, Legionellales and many other notable genera. Others are free-living (non-parasitic) and include many of the bacteria responsible for nitrogen fixation.
Tiger beetles are a large group of beetles, from the Cicindelinae subfamily, known for their aggressive predatory habits and running speed. The fastest known species of tiger beetle, Cicindela hudsoni, can run at a speed of 9 km/h, or about 125 body lengths per second. As of 2005, about 2,600 species and subspecies were known, with the richest diversity in the Oriental (Indo-Malayan) region, followed by the Neotropics.
Ground beetles are a large, cosmopolitan family of beetles, Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. It is one of the ten most speciose animal families, as of 2015.
Passalidae is a family of beetles known variously as "bessbugs", "bess beetles", "betsy beetles" or "horned passalus beetles". Nearly all of the 500-odd species are tropical; species found in North America are notable for their size, ranging from 20–43 mm, for having a single "horn" on the head, and for a form of social behavior unusual among beetles.
The Trachypachidae are a family of beetles that generally resemble small ground beetles, but that are distinguished by the large coxae of their rearmost legs. There are only six known extant species in the family, with four species of Trachypachus found in northern Eurasia and northern North America, and two species of Systolosoma in Chile. They were much more diverse in the past, with many members belonging to the extinct subfamily Eodromeinae, the first fossils known of this family are of the genera Petrodromeus and Permunda from the Permian-Triassic boundary of Russia.
The Nitrosomonadales are an order of the class Betaproteobacteria in the phylum "Proteobacteria". Like all members of their class, they are Gram-negative.
The Rhodocyclales are an order of the class Betaproteobacteria in the phylum "Proteobacteria". Following a major reclassification of the class in 2017, the previously monofamilial order was split into three families:
Derodontidae is a family of beetles, in its own superfamily, Derodontoidea, sometimes known as the tooth-necked fungus beetles. Beetles of this family are small, between 2 and 6 mm in length, with spiny margins on their pronotum that give them their name. The genus, Laricobius, lacks these spines. They have two ocelli on the top of their heads.
Ulmus pseudopropinquaWang & Li, occasionally known in the United States as the Harbin spring elm, is a small deciduous tree found only in Heilongjiang, the northeasternmost province in China. The tree has not been studied comprehensively, and it has been speculated it may be a natural hybrid of Ulmus davidiana var. japonica and Ulmus macrocarpa.
Lamiinae, commonly called flat-faced longhorns, are a subfamily of the longhorn beetle family (Cerambycidae). The subfamily includes over 750 genera, rivaled in diversity within the family only by the subfamily Cerambycinae.
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.
Jacobsoniidae is a family of beetles. The larvae and adults live under bark, in plant litter, fungi, bat guano and rotten wood. It is a small family with 23 described species in three genera:
Silvanidae, "silvan flat bark beetles", is a family of beetles in the superfamily Cucujoidea, consisting of 58 described genera and about 500 described species. The family is represented on all continents except Antarctica, and is most diverse at both the generic and species levels in the Old World tropics.
Byturidae, also known as Fruitworms, is a very small family of beetles, in the suborder Polyphaga, comprising fewer than 20 species worldwide. The larvae of some species develop in fruits. Byturus unicolor affects species of Rubus and Geum.
Ischiopsopha are beetles from the subfamily Cetoniinae, tribe Schizorhinini. The genus was created by Raffaello Gestro in 1874. The type species of the genus is Cetonia bifasciata Quoy & Gaimard, 1824. These cetoniids have the tip of the scutellum visible. The genus is spread throughout the whole Australian region.
Camptodontornis is an extinct genus of enantiornithine bird which existed in what is now Chaoyang in Liaoning Province, China during the early Cretaceous period. It is known from a well-preserved skeleton including a skull found in the Jiufotang Formation of Liaoning Province. Its original generic name was "Camptodontus" ; it was named by Li Li, En-pu Gong, Li-dong Zhang, Ya-jun Yang and Lian-hai Hou in 2010. However, the name had previously been used for a genus of beetle. The type species is "Camptodontus" yangi. Demirjian (2019) coined a replacement generic name Camptodontornis. The status of C. yangi as a distinct species is disputed, with Wang et al. (2015) considering it to be a probable synonym of Longipteryx chaoyangensis.
Collagonum is a genus of beetles in the family Carabidae, containing the following species:
Fortagonum is a genus of beetles in the family Carabidae, containing the following species:
Skoeda is a genus of beetles in the family Carabidae, containing the following species:
Lymphotropha is a genus of parasitic alveolates in the phylum Apicomplexa.
