occiput (synonym)
Located in the direction of the apex of the abdomen when considering a position along the longitudinal axis. Even a structure near the head has a side that is directed towards apex of the abdomen. Likewise, every structure perpendicular to the longitudinal axis of the body (leg, wing) has a side that is directed towards the apex of the abdomen.
posterior cubital cell
Cell that may be present in the base of the wing and that is formed by joining of the second anterior cubital vein (CuA2) and the first anal vein (A1). If these two veins are approximated but not closing the cell (for example in Diastatidae) the cell is open. If either or both veins are missing, or if both veins run to thw wing margin, the cell is absent.
Also known as: anal cell, cell cup.
posterior notopleural setae
Large setae placed on the posterior part of the notopleuron, immediately anterior of the mesonotal suture.
Located in the plane between posterior and dorsal.
Located in the plane between posterior and ventral.
postpronotal lobe
Lateral part of the postpronotum, especially in higher Diptera well visible, less so in some groups of lower Diepra (in particular Nematocera). Usually well intergrated with the scutum and often bearing setae (postpronotal setae).
Synonyms: humerus (plural: humeri), humeral callus (plural: humeral calli)
postpronotal seta
Seta on the postpronotal lobe.
Synonym: humeral seta, humeral bristle.
Posterior of the transverse suture of the scutum
pre-alar setae (synonym)
pre-alar setae
The anterior setae of the postsutural supra-alar setae.
predictive value
The biological, faunistic and other information attached to a taxon. Some species level taxa have low predictive value since almost nothing is known about them. Others have high predictive value, for example, Musca domestica, about which millions of words have been written.
Families obviously have lower predictive value than species.

presc ac
prescutellar acrostichal setae (synonym)
prescutellar acrostichal setae
Prescutellar acrostichal setae are postsutural acrostichal setae but the term is reserved for one pair (sometimes more) of acrostichal setae that are placed just before the scutellum and that are larger than the remaining acrostichal setae.
bent forward (usually used to indicate curvature of setae)
Anteroventral sclerite of the (pro)thorax roughly situated between the attachment of the head and the anterior coxae.
Plural: pupae. The name for the third main stage in the life of an insect that undergoes complete metamorphosis, i.e., develops from the egg through larval and the pupal stages to the adult (holometabolous). All Diptera undergo complete metamorphosis and have a pupal stage. Pupae of Diptera are of two main types; obtect pupae have visible head appendages, wings and legs which lie in sheaths attached to the surface of the body (all Diptera except Cyclorrhapha). Exarate pupae (Cyclorrhapha only) have free appendages. These free appedages are not visible as the pupa lies within the last larval instar skin which is hardened (puparium). Such Diptera pupae are called coarctate.
Recommended literature: Smith, K.V.G., 1989. An introduction to the immature stages of British flies. Diptera larvae, with notes on eggs, puparia and pupae. - Handbooks for the Identification of British Insects 10(14): 1-280. As an excellent reference with keys to suborders, families, subfamilies and genera. For Cyclorrhapha the key applies equally since they have puparia (although the parts may be harder to see).
Plural: puparia. Case formed by the hardening of the last larval skin, in which the pupa is formed. The puparium may exhibit useful taxonomic characters.

To transform to a pupa.
Generally regarded as such, supposed, or reputed to be.
Usage example: 'Further analysis of the integument of this putative second instar (Fig. 3b) indicated that...'. Here the integument was generally believed to be of a second instar larva but may not have been. When a species is ' putatively identified' it means that identification is not certain and should be considered preliminary.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol
