This is a labelled version of the 1st photo in this series...intended to help readers interpret the terminology used in the literature on Cerioidini. For thoracic terms, the legend within the photo gives the "older terms" first, followed by the corresponding "MND(1)
terms" (for details see below).
Note that older papers (e.g. by Williston, Shannon, Curran, Hull, etc.) used thoracic terms like "mesopleuron, sternopleuron, pteropleuron, pleurotergite, and laterotergite" in describing diagnostic characters (e.g. the position of yellow spots). These are diagrammed and discussed in Williston(1908)
...with a better & more detailed diagram appearing on pg. 15 of Thompson(1981) [PDF here
With the 1981 publication of the the MND(1)
, a more stardardized technical terminology for Diptera was introduced and slowly began to proliferate in the literature. For example, the MND thoracic terms "anepisternum, katepisternum, anepimeron, katatergite, and anatergite" correspond to the the older thoracic terms in quotes in the preceding paragraph. See the diagram on pg. 359 of Thompson(1999), available as a PDF here
...which, BTW, is a very useful glossary(!)
for Syrphidae. (It appeared at the end of Thompson's 1999 paper on the genera of neotropical Syrphidae.)
PS: A great way to see the correspondence between the "old thoracic terms" and the more recent "MND thoracic terms" is to view, side-by-side, both Fig. 9 on pg. 15 of Thompson(1981)
and Fig. 8 on pg. 359 of Thompson(1999)
. (You could even make your own "reference card" by cutting & pasting those figures and placing them next to each other in a separate image file ;-)
Postscript 7/4/19: Long after creating this labelled diagram and posting it here, I ran into the wonderful(!) reference link here for thoracic terminology. It's focused on Tephritidae, but (aside from the chaetotaxy) the morphology is quite closely homologous to that of interest for Cerioidini here. Note the glossary there does an excellent job of cross-referencing terminology used by past authors with more current (i.e. "MND(1)-style") vocabulary.
