bibliographic reference

For nomenclatural purposes this is the citation of the author and date of publication. A full bibliographic reference would include, in addition to the author's name and the year, the citation of the exact source of the scientific name, for example, the title of the book or journal, volume, page, etc.: Syrphus vitripennis Meigen, 1822 (Meig. Syst. Beschr. III, 308, 50).

binominal nomenclature

The generally accepted system of nomenclature, adopted by the International Congress of Zoology, by which the scientific name of an animal is designated by both a generic and a specific name: the system under which each species receives a name consisting of two words, of which the first is the generic name and the second is the specific name, e.g., Musca domestica.

biosystematics

Biosystematics is the word for the science encompassing taxonomy, systematics, biology, ecology and spatial and geographical distribution. It provides information to support many fields of (biological) research and beneficial applied programmes.

boreal

1. As in 'boreal species': A species occuring in subarctic (Northern hemisphere) and subantarctic (Southern hemisphere) zones, although Austral is the preferred term for the latter. For example: the distribution of Dolichopus maculipennis Zett. is given as "arctic-high boreal" by Ringdahl (1951) and as "a boreal moorland species" from the Soviet Union, Finland, Sweden, Norway and Denmark by Stackleberg (1933).
2. As in 'boreal' region, habitat or system: Subarctic ecosystems (Northern hemisphere).

brachypterous

With short wings, short-winged. See brachyptery

brachyptery

A condition where the size of the wing is reduced in comparison with a normally winged specimen. A distinction should be made between 'small-winged' species, that always have short, but fully functional wings, and brachypterous species, in which wing size in some or all individuals has been reduced to such an extent that flight is impossible.
Brachyptery is often found in species that have a parasitic, terrestrial or even subterranean life style or that are found in other circumstances where wings are of little uses (e.g., boreal conditions or locations without natural enemies like some oceanic islands).
Within certain species fully-winged individuals may occur next to brachypterous individuals and/or apterous header=[apterous] body=[Without wings, wingless. See aptery.<br /><img src='../../infusions//terms/images/no_image.gif' style='vertical-align:middle;' />] delay=[0] fade=[on]

individuals.

bristle

seta (synonym)

callus

Plural: calli.
Bare and shining area on the frons, in particular in some groups of orthorrhaphous Diptera, e.g., Tabanidae and (female) Therevidae.

callus

Plural: calli.
Mound-like, rounded or elongate swelling of the exoskeleton (the body surface), especially on the thorax; see: humeral callus, prealar callus, postalar callus.

calypter

The posterobasal portion of the axillary membrane, joining the hind margin of the wing to the thorax, forms two basal lobes called the calypteres (sing. calypter; squamae, squamulae). The proximal lobe, called the lower calypter

, begins as a narrow, membranous ligament arising from the furrow between the scutellum and the postnotum and ends where the more distal lobe, the upper calypter

header=[upper calypter] body=[The distal lobe of the posterobasal portion of the axillary membrane that joins the hind margin of the wing to the thorax is called the upper calypter. It begins the membrane folds over then lower calypter. It is usually larger than the lower calypter, but in some groups, e.g. Tabanidae, Acroceridae, and many Calyptratae, the lower calypter is larger than the upper one. <br /><img src='../../infusions//terms/images/no_image.gif' style='vertical-align:middle;' />] delay=[0] fade=[on]

, folds sharply over it.

calyptral fold

Fold between the lower calypter

and upper calypter

calyptral fringe

The fringe of hairs along the posterior margin of each calypter.

Calyptratae

Calyptratae is a subsection of Schizophora in the insect order Diptera, commonly referred to as the calyptrate muscoids (or simply calyptrates). It consists of those flies which possess a calypter that covers the halteres, among which are some of the most familiar of all flies, such as the house fly.
