Hi.
I would like to know if there is a guide, manual, book etc, which talks about the definition, diversity, shape and illustration of different types of setae on mite body segments (dorsum, legs, palp etc). I feel like, adding to my confusion, there are some shapes which are called by different names but represent one structure. On the internet, I could search for all those shapes but is there resource which clearly defines and describes all acarid setae?
Thanks a zillion,
Jawwad.
Hi Jawwad,
Jenny Beard and I recommended following the terminology used in the Kew Plant Glossary by Beentje. See our paper on Ultratenuipalpus: "A review of Ultratenuipalpus (Trombidiformes: Tenuipalpidae) and related genera, with a new species from forest oak Allocasuarina torulosa (Aiton) (Casuarinaceae)".
That paper by Beentje is especially useful for flat mites, which have leaf-like setae - look especially at page 133. It's still a little ambiguous on "lanceolate" (use Lindley's form), a much-misinterpreted term, but otherwise is an excellent way to standardise terms for setae. I presume Beentje's terms have been used in botanical circles for a long time, so there's plenty of precedence for them.
If you need a copy of Beentje's plate of leaf shapes, please get in touch.
best wishes, Owen.
Dear Dr. Owen Seeman
I am grateful for your usual prompt and wonderful reply. I respect your and Dr. Jenny Beard's recommendation and will benefit from it. I already have a copy of your excellent Tenuiplapid paper. It provides a comprehensive knowledge. I may search for Beentje's work, and if I am unsuccessful, I will reach out.
Regards
Jawwad
