Myxophaga is the second-smallest suborder of the Coleoptera after Archostemata, consisting of roughly 65 species of small to minute beetles in four families. The members of this suborder are aquatic and semiaquatic, and feed on algae.
The Stephanidae, sometimes called crown wasps, are a family of parasitoid wasps. They are the only living members of the superfamily Stephanoidea. Stephanidae has at least 345 living species in 11 genera. The family is considered cosmopolitan in distribution, with the highest species concentrations in subtropical and moderate climate zones. Stephanidae also contain four extinct genera described from both compression fossils and inclusions in amber.
Glomerida is an order of pill-millipedes found primarily in the Northern Hemisphere. They superficially resemble pill-bugs or woodlice, and can enroll into a protective ball. They have twelve body segments, 17 to 19 pairs of legs, and males have enlarged rear legs involved in mating. The order includes about 30 genera and at least 280 species, including Glomeris marginata, the common European pill-millipede. The order contains members in Europe, South-east Asia and the Americas from California to Guatemala. Although historically considered closely related with the similar sphaerotheriidans that also enroll, some DNA evidence suggest they may be more closely related to glomeridesmidans, a poorly known order that does not enroll.
Spirostreptida is an order of long, cylindrical millipedes. There are approximately 1000 described species, making Spirostreptida the third largest order of millipedes after Polydesmida and Chordeumatida.
A woodlouse is a crustacean from the monophyletic suborder Oniscidea within the isopods. They get their name from often being found in old wood.
Nanoraphidia is an extinct genus of snakefly in the family Mesoraphidiidae containing the species Nanoraphidia electroburmica and Nanoraphidia lithographica.
Kachinus is an extinct genus of ant-like stone beetle in the family Staphylinidae containing the single species Kachinus antennatus.
The Brachypsectridae are a family of beetles commonly known as the Texas beetles. There are only two extant genera, Brachypsectra and Asiopsectra. The type species, Brachypsectra fulva, occurs in North America. Other species in the genus have a cosmopolitan distribution. Two other extant and fossil species have been described from the Dominican Republic. While formerly considered monogeneric, in 2016 Asiopsectra was described from specimens found in Iran and Tajikistan. Two extinct genera, Vetubrachypsectra and Hongipsectra, known from adults, and a larval genus, Cretopsectra are known from Cenomanian aged Burmese amber.
Plumalexius is a genus of wasps in the extinct monotypic family Plumalexiidae, containing two species: the type species Plumalexius rasnitsyni, known from the Late Cretaceous White Oaks Pit in Sayreville, New Jersey, and Plumalexius ohmkuhnlei, known from the Cretaceous Burmese amber.
Astreptolabis is an extinct genus of earwig in the Dermaptera family Pygidicranidae known from a group of Cretaceous fossils found in Myanmar. The genus contains two described species, Astreptolabis ethirosomatia and Astreptolabis laevis and is the sole member of the subfamily Astreptolabidinae.
Tytthodiplatys is an extinct genus of earwig in the family Diplatyidae known from a Cretaceous fossil found in Myanmar. The genus contains a single described species, Tytthodiplatys mecynocercus.
Platydesmida is an order of millipedes containing two families and over 60 species. Some species practice paternal care, in which males guard the eggs.
Siphonophorida is an order of millipedes containing two families and over 100 species.
Callipodida is an order of millipedes containing around 130 species, many characterized by crests or ridges.
Siphoniulus is a poorly known genus of millipede containing only two living species: S. alba from Indonesia, and S. neotropicus from Mexico and Guatemala. An additional two fossil species are known from Cretaceous amber. Siphoniulus species are the only members of the family Siphoniulidae and order Siphoniulida, making Siphoniulida the smallest millipede order. Few specimens are known, and their classification is contentious, although most recent studies place them as basal members of the Helminthomorpha.
Zigrasolabis is an extinct genus of earwig in the family Labiduridae known from Cretaceous fossils found in Myanmar. The genus contains a single described species, Zigrasolabis speciosa.
Toxolabis is an extinct genus of earwig in the dermapteran family Anisolabididae known from a Cretaceous fossil found in Burma. The genus contains a single described species, Toxolabis zigrasi.
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 Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its alleged role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected.
Paradoxosisyra is an extinct genus of lacewing in the spongefly family, Sisyridae. The genus contains a single species, Paradoxosisyra groehni and is placed into the extinct subfamily Paradoxosisyrinae. Paradoxosisyra is known from a solitary Middle Cretaceous fossil which was found in Asia.
Valeseguyidae is a family of flies, belonging to Scatopsoidea. It contains only one known extant species, Valeseguya rieki, known from a single male specimen found in Victoria, Australia, described in 1990. It was initially classifed as a member of the wood gnat family Mycetobiidae, but was later given its own family in 2006. Two fossil species are known, including another species of Valeseguya, V. disjuncta, which is known from Miocene aged Dominican amber from the Caribbean, and Cretoseguya, containing the single species C. burmitica, which is known from the mid-Cretaceous Burmese amber of Myanmar, dating to around 100 million years ago.
