Orthorrhapha

Last updated

Orthorrhapha is a circumscriptional name which historically was used in entomology for an infraorder of Brachycera, one of the two suborders into which the order Diptera, the flies, are divided. As the group was paraphyletic, it has not been used in classifications in the last decade, and is effectively obsolete. However, many catalogs, checklists, and older works still contain the name. The taxa that used to be in the Orthorrhapha now comprise all of the infraorders in Brachycera excluding the Muscomorpha (= "Cyclorrhapha").

The recent revision of the taxonomy of the order Diptera by Pape et al. [1] revived the name Orthorrhapha.

Theodor Becker was a Danish-born German civil engineer and entomologist primarily known for studies on the taxonomy of flies.

The Nymphomyiidae are a family of tiny (2 mm) slender, delicate flies (Diptera). Larvae are found among aquatic mosses in small, rapid streams in northern regions of the world, including northeastern North America, Japan, the Himalayas, and eastern Russia. Around a dozen extant species are known, with two fossil species found in amber, extending back to the Mid Cretaceous. Under an alternative classification, they are considered the only living representatives of a separate, suborder called Archidiptera which includes several Triassic fossil members. The family has characteristics associated with the Nematocera as well as the Brachycera. The antennae are shortened as in the Brachycera and these flies are long, having a snout with vestigeal mouthparts, non-differentiated abdominal segments with large cerci. The wings are narrow and hair-fringed and have very weak venation. They are known to form cloud-like swarms in summer and the short-lived non-feeding adults have wings that fracture at the base shortly after mating.

The Brachyceran infraorder Tabanomorpha is a small group that consists primarily of two large families, the Tabanidae and Rhagionidae, and an assortment of very small affiliated families, most of which have been included within the Rhagionidae.

<span class="mw-page-title-main">Vermileonidae</span> Family of wormlion flies

The Brachyceran family Vermileonidae is a small family of uncertain affinities and unusual biology. It includes fewer than 80 described species, most of them rare and with restricted distribution, in 10 genera. Historically the vermileonids had been regarded as belonging to the family Rhagionidae, possibly in a subfamily Vermileoninae. Their biology and morphology are so markedly distinct from the main Rhagionidae sensu stricto however, that the placement as a separate family has been widely accepted.

<span class="mw-page-title-main">Muscomorpha</span> Order of flies

The Brachyceran infraorder Muscomorpha is a large and diverse group of flies, containing the bulk of the Brachycera and most of the known flies. It includes a number of the most familiar flies, such as the housefly, the fruit fly, and the blow fly. The antennae are short, usually three-segmented, with a dorsal arista. Their bodies are often highly setose, and the pattern of setae is often taxonomically important.

Dipteran morphology differs in some significant ways from the broader morphology of insects. The Diptera is a very large and diverse order of mostly small to medium-sized insects. They have prominent compound eyes on a mobile head, and one pair of functional, membraneous wings, which are attached to a complex mesothorax. The second pair of wings, on the metathorax, are reduced to halteres. The order's fundamental peculiarity is its remarkable specialization in terms of wing shape and the morpho-anatomical adaptation of the thorax – features which lend particular agility to its flying forms. The filiform, stylate or aristate antennae correlate with the Nematocera, Brachycera and Cyclorrhapha taxa respectively. It displays substantial morphological uniformity in lower taxa, especially at the level of genus or species. The configuration of integumental bristles is of fundamental importance in their taxonomy, as is wing venation. It displays a complete metamorphosis, or holometabolous development. The larvae are legless, and have head capsules with mandibulate mouthparts in the Nematocera. The larvae of "higher flies" (Brachycera) are however headless and wormlike, and display only three instars. Pupae are obtect in the Nematocera, or coarcate in Brachycera.

Rhagionemestriidae is an extinct family of brachyceran flies known from the Jurassic and Cretaceous periods. It was first named as a subfamily of the Nemestrinidae by Ussatchov (1968), and was raised to full family status by Nagatomi and Yang (1998). They are considered to be closely related to the family Acroceridae. Similar to Acroceridae, members of the family possess a large hemispherical head, with eyes covering nearly all of the area.
