dorsocentral setae (synonym)
diagnostic character
A character that is common to (virtually) all members of a group and that in itself, or in combination with other diagnostic characters, is unique to that group. For example: empodia pulviliform; branches of R crowded on costal margin; wing often with fine longitudinal wrinkles are all diagnostic characters for the taxon Stratiomyidae. Compare with differential character.

diapause
A suspension (temporary halt) of development that can occur at the egg, larval, pupal, or adult stage, depending on the species. In some species, diapause is facultative, occuring only when induced by environmental conditions; in other species the diapause period is an obligatory part of the life cycle.

differential character
A character which separates one group from another. For example: hind tibiae with distinct long anteroventral bristles is a differential character between the hybotid (sub)genera Elaphropeza and Drapetis; present in Elaphropeza and absent in Drapetis. Compare with diagnostic character.

disticalypter
upper calypter (synonym)
dorsal
1. Located on the dorsum. 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 dorsum. For example, a seta can be located dorsal to another seta.

Opposite: ventral.
dorsocentral setae
Setae placed lateral of the median area of the mesonotum; meaning that they are placed lateral of the acrostichal setae (if these latter are present). If the mesonotum is completely covered with smaller and larger setae, then dorsocentral setae should be distinguishable by their larger size compared to the immediate surrounding setae. Dorsocentral setae may be pre-sutural (in front of the suture) or post-sutural (behind the suture).
dorsocentral setae
One or more longitudinal, paramedian rows of setae on the scutum. Sometimes the 'rows' consists of a single setae, which it then most often placed close to the posterior margin of the scutum. In several groups the number, size and position of dorsocentral setae is of diagnostic importance, for example the number of presutural and postsutural dorsocentral setae (given as a formula like 0+2 or 1+4 for the presutral and postsutural dorsocentral setae).

dorsum
The side if the fly that we would indicate as 'the back' in human terms. In practice this means the side where the wings are placed (or would have been placed if the insect is apterous).
Adjective: dorsal.
Opposite: venter.
