Diplotriaenidae is a family of spirurian nematodes. Like all their relatives, they have neither a circulatory a or respiratory system. They are the only family in superfamily Diplotriaenoidea, if the Oswaldofilariidae are correctly placed with the Filarioidea and not here.

Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

Spiruria subclass of roundworms

Subclass Spiruria comprises mostly parasitic secernentean nematodes. In an alternate classification, they are treated as suborder Spirurina, with the orders listed here being ranked as infraorders.

Nematode phylum of animals with tubular digestive systems with openings at both ends

The nematodes or roundworms constitute the phylum Nematoda. They are a diverse animal phylum inhabiting a broad range of environments. Taxonomically, they are classified along with insects and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends.

Systematics

Subfamilies and genera of Diplotriaenidae are:

Subfamily Diplotriaeninae

Clupeiformes order of fishes

Clupeiformes is the order of ray-finned fish that includes the herring family, Clupeidae, and the anchovy family, Engraulidae. The group includes many of the most important forage and food fish.

Curculionidae family of insects

The Curculionidae are the family of the "true" weevils. They are one of the largest animal families, with 6,800 genera and 83,000 species described worldwide.

Apidae family of bees

Apidae is the largest family within the superfamily Apoidea, containing at least 5700 species of bees. The family includes some of the most commonly seen bees, including bumblebees and honey bees, but also includes stingless bees, carpenter bees, orchid bees, cuckoo bees, and a number of other less widely known groups. Many are valuable pollinators in natural habitats and for agricultural crops.

Eulipotyphla order of tetrapods

Eulipotyphla is an order of mammals suggested by molecular methods of phylogenetic reconstruction, and includes the laurasiatherian members of the now-invalid polyphyletic order Lipotyphla, but not the afrotherian members. Lipotyphla in turn had been derived by removing a number of groups from Insectivora, the previously used wastebasket taxon.

Colubridae Family of snakes

Colubridae is a family of snakes. With 524 genera and approximately 1,760 species, it is the largest snake family, and includes just over 51% of all known living snake species. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica.

Nymphalidae family of insects

The Nymphalidae are the largest family of butterflies with more than 6,000 species distributed throughout most of the world, belonging to the superfamily Papilionoidea. These are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings.

Leaf beetle family of insects

The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but only some of them are listed below. The precise taxonomy and systematics are likely to change with ongoing research.

Crambidae Family of insects

The Crambidae are the grass moth family of lepidopterans. They are variable in appearance, the nominal subfamily Crambinae taking up closely folded postures on grass stems where they are inconspicuous, while other subfamilies include brightly coloured and patterned insects which rest in wing-spread attitudes.

Cricetidae family of mammals

The Cricetidae are a family of rodents in the large and complex superfamily Muroidea. It includes true hamsters, voles, lemmings, and New World rats and mice. At almost 608 species, it is the second-largest family of mammals, and has members throughout the Americas, Europe and Asia.

Bostrichoidea superfamily of insects

Bostrichoidea is a superfamily of beetles. It is the type superfamily of the infraorder Bostrichiformia.

Derodontidae family of insects

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.

Asparagaceae family of plants

Asparagaceae is a family of flowering plants, placed in the order Asparagales of the monocots. Its best known member is Asparagus officinalis, garden asparagus.

Cossidae family of insects

The Cossidae, the cossid millers or carpenter millers, make up a family of mostly large miller moths. This family contains over 110 genera with almost 700 known species, and many more species await description. Carpenter millers are nocturnal Lepidoptera found worldwide, except the Southeast Asian subfamily Ratardinae, which is mostly active during the day.

Calpinae subfamily of insects

The Calpinae are a subfamily of moths in the family Erebidae. This subfamily includes many species of moths that have a pointed and barbed proboscis adapted to piercing the skins of fruit to feed on juice, and in the case of the several Calyptra species of vampire moths, to piercing the skins of mammals to feed on blood. The subfamily contains some large moths with wingspans longer than 5 cm (2 in).

Ennominae subfamily of insects

Ennominae is the largest subfamily of the geometer moth family (Geometridae) with some 9,700 described species in 1,100 genera. They are usually a fairly small moth species, though some grow to be considerably large. This subfamily has a global distribution. It includes some species that are notorious defoliating pests. The subfamily was first described by Philogène Auguste Joseph Duponchel in 1845.

Alethinophidia infraorder of reptiles

The Alethinophidia are an infraorder of snakes that includes all snakes other than blind snakes and thread snakes. Snakes have long been grouped into families within Alethinophidia based on their morphology, especially that of their teeth. More modern phylogenetic hypotheses using genetic data support the recognition of 19 extant families, although the taxonomy of alethinophidian snakes has long been debated, and ultimately the decision whether to assign a particular clade to a particular Linnaean rank is arbitrary.

Euplerinae subfamily of carnivorans

Euplerinae, more commonly known as malagasy civets, is a subfamily of carnivorans that includes four species restricted to Madagascar. Together with the subfamily Galidiinae, which also only occurs on Madagascar, it forms the family Eupleridae. Members of this subfamily, which include the fossa, falanoucs and Malagasy civet, were placed in families like Felidae and Viverridae before genetic data indicated their consanguinity with other Madagascar carnivorans. Within the subfamily, the falanouc and Malagasy civet are more closely related to each other than to the fossa.

Erebidae family of insects

The Erebidae are a family of moths in the superfamily Noctuoidea. The family is among the largest families of moths by species count and contains a wide variety of well-known macromoth groups. The family includes the underwings (Catocala); litter moths (Herminiinae); tiger, lichen, and wasp moths (Arctiinae); tussock moths (Lymantriinae), including the arctic woolly bear moth ; piercing moths ; micronoctuoid moths (Micronoctuini); snout moths (Hypeninae); and zales, though many of these common names can also refer to moths outside the Erebidae. Some of the erebid moths are called owlets.

Colubroidea superfamily of reptiles

Colubroidea is a superfamily of snakes in the clade Colubroides that include Colubridae and a few other related families. In addition to colubrids, the past Colubroidea used various other caenophidian snakes like cobras and vipers as these snakes form a clade. However these same studies also found in support of dividing the family Colubridae into several distinct, but related, families. Zaher et al. (2009) proposed to redefine Colubroidea for colubrids and related families, while naming Colubroides for the group containing vipers, cobras as well as colubroids.
