Particular attention is given to key characters, because it is essential that they be interpreted correctly. You can use additional photographs within the key when you are unsure of the character state discussed in the text. A double click on the character state thumbnail opens the related character state photograph and the mouse cursor will surround the important specific character state.

ANTECOSTA: Anterior sclerite (pre- or acrotergite or pre- or acrosternite) of the antecostal ridge of a tergite or sternite.
 character state
ANTECOSTAL RIDGE: The groove that delimits the posterior base of the antecosta (= intersegmental groove).
ANTEROANGULAR: Anterolateral corner of a sclerite (Latin, anterior = before, to the front of, angular = corner)
ANTEROMARGINAL: (Latin, anterior = before, or to the front of, margo = edge) narrow part of a surface within the edge, anteromarginal setae: setae inserted on the anterior margin of a sclerite.
APODEME: (Greek, apo = away, demas = body), apodem IX = a ridge process of tergite IX that forms a part of the insect endoskeleton and provides surface for the attachment of ovipositor muscles.
BASANTRA: In the family Phlaeothripidae a pair of sclerites on each side of the anterior half of the ventral surface of the prothorax as parts of the prosternum.
CAMPANIFORM SENSILLA: Sense organ that lacks an external process and displays the form of a simple circular pore or hollow cone in the cuticular surface (typical in thrips are the presence or absence of CS of the Metanotum craniale).
