Xiphiagrion is a small genus of damselflies of the family Coenagrionidae. It has only two species: Xiphiagrion cyanomelas and Xiphiagrion truncatum . [3]
Damselflies are insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller, have slimmer bodies, and most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica.
The insect family Coenagrionidae is placed in the order Odonata and the suborder Zygoptera. The Zygoptera are the damselflies, which although less known than the dragonflies, are no less common. More than 1,300 species are in this family, making it the largest damselfly family. The family Coenagrionidae has six subfamilies: Agriocnemidinae, Argiinae, Coenagrioninae, Ischnurinae, Leptobasinae, and Pseudagrioninae.
Argia is a genus of damselflies of the family Coenagrionidae and of the subfamily Argiinae. It is a diverse genus which contains about 114 species and many more to be described. It is also the largest genus in Argiinae. They are found in the Western Hemisphere. They are commonly known as dancers. Although the genus name comes from Ancient Greek: ἀργία, romanized: argia, lit. 'laziness', dancers are quite active and alert damselflies. The bluer Argia species may be confused with Enallagma species.
Somatochlora, or the striped emeralds, is a genus of dragonflies in the family Corduliidae with 44 described species found across the Northern Hemisphere.
The Platycnemididae are a family of damselflies. They are known commonly as white-legged damselflies. There are over 400 species native to the Old World. The family is divided into several subfamilies.
Muscicapa is a genus of passerine birds belonging to the Old World flycatcher family Muscicapidae, and therein to the typical flycatchers of subfamily Muscicapinae. They are widespread across Europe, Africa and Asia with most species occurring in forest and woodland habitats. Several species are migratory, moving south from Europe and northern Asia for the winter.
The purplish jay is a species of bird in the family Corvidae. It is found in northern Argentina, Bolivia, southern Brazil, Paraguay and southeastern Peru. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and heavily degraded former forest.
The opal-rumped tanager is a species of bird in the family Thraupidae. It is found in the Amazon and Atlantic Forest of South America. The population of the Atlantic Forest has a far paler chest than the other populations, and has often been considered a separate species as the silvery-breasted tanager. Today most authorities treat it as a subspecies of the opal-rumped tanager.
The blue-mantled crested flycatcher or African crested flycatcher is a species of bird in the family Monarchidae found in eastern and south-eastern Africa.
Coenagrion is a genus of damselflies in the family Coenagrionidae, commonly called the Eurasian Bluets. Species of Coenagrion are generally medium-sized, brightly coloured damselflies.
Chlorocyphidae is a family of damselflies, commonly known as jewels. These are colorful species native to the Old World tropics, where they occur along forest streams. They are most diverse in Southeast Asia.
Didaphne is a monotypic moth genus in the subfamily Arctiinae erected by Carlos Berg in 1899. Its only species, Didaphne cyanomela, was described by Neumoegen in 1894. It is found on Cuba.
Platystictidae is a family of damselflies, commonly known as shadowdamsels. They look very similar to the threadtail damselfly family (Protoneuridae). They can mostly be found throughout Asia, Central America, and South America.
Lestes sponsa, is a damselfly, with a wide Palaearctic distribution. It is known commonly as the emerald damselfly or common spreadwing. Both males and females have a metallic green colour and when resting its wings are usually half opened.
Diphlebiidae is no longer recognised as a biological family. It was the name given to a small family of damselflies, the azure damselflies, with species in two genera: Diphlebia and Philoganga. Diphlebia is found in Australia and Philoganga is found in Southeast Asia. They are large and thick-bodied damselflies. They rest with their wings spread out. The Diphlebiidae were also known as Philogangidae.
Odax is a genus of marine ray-finned fish, weed whitings from the family Odacidae which are native to the Pacific waters of New Zealand.
The herring cale is a species of ray-finned fish, a weed whiting from the family Odacidae which is endemic to Australia where it is found along the southern and south eastern coast. It inhabits the surf zone, ranging to a depth of 30 m (98 ft) in rocky areas with plentiful growth of brown algae, which it feeds on. This species grows to a length of 51 cm (20 in) SL. This species is the only known member of the genus Olisthops, but it has frequently been placed in Odax instead.
Coeliccia is a genus of damselflies in the family Platycnemididae. They are distributed in Asia from India to Japan to Indonesia. It is the largest genus in the family, with around 80 species.
Umma gumma is a species of damselfly in the family Calopterygidae. The genus name was established in 1890 and this species described in 2015 from Africa was found to belong to the genus. The species was named after the Pink Floyd album Ummagumma.
Lestoidea is a genus of damselflies in the family Lestoideidae, commonly known as bluestreaks. Its species are endemic to north-east Queensland, Australia, where they inhabit rainforest streams.
