Plural: tibiae.

tip
apex (synonym)
tomentose
With tomentum. For example: Dasybasis elquiensis (Tabanidae): 'Tergites I to VI with broad greyish tomentose median posterior spots. Tergites III-VI with pale greyish tomentose sublateral spots.'
tomentum
Pubescence that is composed of matted hair; a covering of short, flattened, recumbent, scale-like hair which merges gradually into dust or pollen. The colour may change with the angle of view.
tomentum
pollinosity (synonym)
triserial

tsetse fly
Vernacular name for species in the genus Glossina, the single genus in the family Glossinidae. The name is pronounced /ts/e-/ts/e, teet-SEE, or set-see. Well-known vector of trypanosomiasis.

type genus
The nominal genus that is the name-bearing type of a nominal family-group taxon. (From the Glossary of the International Code of Zoological Nomenclature).
type series
The series of specimens on which the original author bases a new nominal species-group taxon. In the absence of a holotype designation, any such specimen is eligible for subsequent designation as the name-bearing type (lectotype); pending lectotype designation, all the specimens of the type series are syntypes and collectively they constitute the name-bearing type. Excluded from the type series are any specimens that the original author expressly excludes or refers to as distinct variants, or doubtfully includes in the taxon. (From the Glossary of the International Code of Zoological Nomenclature).
type species
The nominal species that is the name-bearing type of a nominal genus or subgenus. (From the Glossary of the International Code of Zoological Nomenclature).
type specimen
Practical: When a biological species is named a single specimen is designated to carry the name. It is a standard of reference and if the species is already described or two species are merged types are maintained in case of dispute. This single specimen is the holotype. Other types are recognized: lectotype is the most significant.
Official: A term used in previous editions of the Code for a holotype, lectotype or neotype, or for any syntype; also used generally for any specimen of the type series. (From the Glossary of the International Code of Zoological Nomenclature).

U
uniserial
In one row.
upper calypter
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.

V
vector
In medical entomology, a vector is an arthropod which carries disease producing organisms (bacteria, virus, filarial worms) to a vertebrate host. For example, several species of Culicidae are vectors for malaria.

venter
The side of the fly that we would indicate as 'the belly' in human terms. On practice this means the side where the mouth is positioned an where the legs are placed.
Adjective: ventral.
Opposite: dorsum.
ventral
1. Located on the venter. For legs this means that these are considered as if they were in the position as given in the illustration. So, even if a leg is pointing upwards in a specimen, one should image that the leg was positioned in a horizontal plane, perpendicular to the body axis.

2. Located in a more position towards the venter. For example, a seta can be located ventral to another seta.

Opposite: dorsal.
ventrite
The ventral surface of one of the body segments. An old term
and now considered synonym of sternite.
vertex
Quote from the Manual of Nearctic Diptera:
The median portion of the upper extremity of the head, bounded by the eyes latterally, the occiput posteriorly and the frons anteriorly, ...

Thus it becomes a rather roughly defined area you could call the posterodorsal margin of the head, in the middle of which you will find the (posterior part of) the ocellar triangle.
vitta
Plural: vittae.
A broad stripe, most often used while describing longitudinal bands on the thorax but can be used for the abdomen and head, when it mostly will be used to describe a cross-band.
E.g.: "Presutural area of scutum with irregular dark brown vittae on lateral margin -Oestrophasia (Cenosoma) sabroskyi."


W
Wikipedia
A free multilingual encyclopaedia. Many of the Diptera pages (best accessed through 'flies') are written by or with the help of authorities. The sites vary in quality but constantly improve. Some pages are technical, others are general. Often the German, Dutch or French versions are better than the English language page but the sites slowly merge as cross translation proceeds. A wiki stub is a page with very litle information awaiting addition.

128 in the New World as of 2009. Should be around 140 worldwide depending on how you split.

@Sundew: You may inadvertedly have been caught in the void of the server switch. I hope all is okay now. I am still ironing out any glitches that appear and/or are reported.

@bioimages: May have been a temporary glitch. I see the new threads with now replies correctly Replies 0.

Seems to be a bug: new posts show with 1 reply which makes it look as though it's already been answered.
