|Glossary of terms for Thysanoptera - (Parasitoids)|
Particular attention is given to key characters, because it is essential that they be interpreted correctly. Compare similar and different character state combinations to be sure your selection is correct. You can use additional photographs within the key when you are unsure of the character state interpretation. A double click on the character state thumbnail in the key opens the related character state photograph(s) and the mouse cursor will surround the important character state. The glossary should train and help you to interpretate key questions and character states correct.

2 or 3 pairs of setae are commonly found on the head in the region of the ocelli; pair 1 if present is in front of the fore ocellus; pair 2 arise laterally near the inner margin of the compound eyes; pair 3 varies in position but is often near the anterolateral margins of the ocellar triangle.
