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

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]

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.

catalog

catalogue (synonym)

catalogue

An nomenclatorial index that gives a list of taxa with relevant taxonomic literature. Catalogues are prepared for particular regions (zoogeographic regions, countries), particular collections (museum collections or, more restrictive, type collections), or particular taxa (families, genera). The taxa are arranged in a convenient way (either alphabetically or systematically) and reference to the literature for each taxon is given, if necessary supplemented with reference to material in collections. Catalogues usually are prepared to provide a list of all relevant taxonomic literature and nomenclatorial issues pertaining to a taxon or the taxa in a particular collection. Example: Stone, A., et al., 1965. A Catalog of the Diptera of America Corth of Mexico, United States Department of Agriculture, Washington, D.C. Also compare with checklist

header=[checklist] body=[Usually a list of species belonging to a particular taxon (class, order, family, genus, etc.) that are found in a particlar region (zoogeographic region, country, nature reserve, etc.). The species are listed according to a convenient or systematic classification (for example, alphabetically or cladistically). Checklists provide a quick reference, for example while arranging collections, establishing the distribution of species, etc. Example: Beuk, P.L.Th, 2002. Checklist of the Diptera of the Netherlands.

cell cup

posterior cubital cell (synonym)

cercal plate

The plate formed when cerci are usually fused along the midline. This structure is recognized in a number of groups in the Empidoidea and within the group of Anthomyiidae, Fanniidae and Muscidae.

cf.

Latin, compare (with); for example, in respect of a determination: Anthomyia cf. pluvialis means that whilst the specimen compares well with pluvialis the determiner is not quite sure and suggests implicitely to compare it with a specimen with undisputed identification.

chaetotaxy

The study of the number and position of setae header=[setae] body=[seta <img src='../../infusions//terms/images/no_image.gif' style='vertical-align:middle;' />] delay=[0] fade=[on]

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

(bristles, chaetae, hairs) on the insects in systematics. The number, shape and placement of many setae is of big importance during identification and often has systematic value as well.
When using setae while identifying specimens, it is recommended always to check both sides (left and right) in case setae are broken or lost altogether on the side examined firsts. Pinned material is prone to breakage but loss also may occur in living flies, especially on legs. The presence of an 'empty' alveolus header=[alveolus] body=[The Glossary contains no matching items.

circumscriptional name

Taxon name used above family-group level (e.g., order or class) which are not ruled by the International Code of Zoological Nomenclature and which are defined by the particular set of members included, not the number of species. A little used term not just relating to the early history of taxonomy but very important for theoretical reasons.
