basal

The adjective base

header=[base] body=[The part nearest to the point of attachment or the attached part of something relative to the (imaginary) center of the body. For example, the start of the wing (base of the wing), the abdomen (base of the abdomen), the tibia (base of the tibia), etc.<br />
For some structures, the use of this term can cause considerable confusion. Since the thorax will generally be considered the (imaginary) center of the body, the anterior margin (near the head) could be considered the base. Yet, in some (little used) interpretations the transition between thorax and abdomen is considered the (imaginary) center of the body, and in that case the part of the thorax that is joined with the abdomen should be considered the base. So, for the thorax it is recommended to avoid the use of this term.<br /><img src='../../infusions//terms/images/no_image.gif' style='vertical-align:middle;' />] delay=[0] fade=[on]

basicalypter

lower calypter (synonym)

basicosta

The distal one of the two plates in the axillary area of the wing along which the costa of the wing articulates. The tegula

header=[tegula] body=[The proximal one of the two plates in the axillary area of the wing located at the extreme base of the costal margin. The basicosta is the distal one.<br />

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. <img src='../../infusions//terms/images/no_image.gif' style='vertical-align:middle;' />] delay=[0] fade=[on]
