Especially for complex terms such as 'postero-dorsal rim of pygophore [genital chamber]'. Is there a general reference or a set of guidelines to look up?
Ashe, J.S. (1994) Evolution of aedeagal paramerres of aleocharine staphylinids (Coleoptera: Staphylinidae: Aleocharinae). The
Canadian Entomologist, 126, 475–491 . This paper contain a lot of abbreviate terminology for insect morphology, especially related to aedeagal morphology in coleopterta!
There is no agreement on such terminology. I suggest you to check several papers and books to find the mostly accepted one. Also I suggest you to add all abreviations on a drawing of a high quality photo, and then explain them in figure caption.
The above quoted author's correct name is TUXEN. And, of course, you can check the papers dealing with morphology. For your use only, you can simply use the first syllabe of the latin name of the segment, as I am doing (e.g. for the leg: Coxa, Trochanter, Femur, Tibia, Praetarsus, Tarsus = Co-Tro- Fe- Ti- Praeta- Ta). I also suggest you to read Snodgrass' s "Principles of Insect Morphology", which is the "Bible" of insect morphology and Berlese' s "Gli Insetii - loro organisatione, morfologia e sviluppo" - the first volume. You will surely find in those books the abbreviations you need. At least Berlese's book can be downloaded in .pdf format from Biodiversity Heritage Library (www.biodiversitylibrary.com) or from Archive (www.archive.com). If you can not download them, send me an e-mail on: [email protected], and I will send to you at least the Berlese's book via wetransfer.com. Hope this will be helpful. Best regards, Dani.
Not exactly abbreviations but a list of important anatomic terms is available in 1977 DuPorte's Manual of Insect Morphology. Many entomologists use this as a reference for their terms of direction and position.
For Hymenoptera, we have tried to come up with an ontology so that terms are standardised. see http://portal.hymao.org/projects/32/public/ontology/
Abbreviations should follow the particular journal style and ususally reserved for ratios etc. These are generally defined in the Materials and Methods section.
See also "A hymenopterists’ guide to the Hymenoptera Anatomy Ontology: utility, clarification, and future directions" in my list of publications.
