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.

OCELLAR TRIANGLE: Area on the dorsal surface (vertex) of the head of winged adults delimited by the 3 ocelli.
character state
OCELLI: Simple eyes of adult winged thrips, typically three in a triangle on the vertex, with one anterior median and two lateral ocelli.
OVIPOSITOR: Ventral paired sclerite constructions of the VII and VIII abdominal segment for laying eggs.
PARAGLOSSA: A pair of lobes distolateral on the prementum, lying outside the glossae.
PEDICEL: The narrowed base of the 1st antennal segment of the flagellum (=3rd antennal segment).
PEDICELLUS: The second segment of the antenna, with intrinsic muscles, forming the pivot between scape and 3rd antennal segment.
PLEURITE: Lateral sclerite between tergite and sternite.
PLEUROTERGITE: Dorsolateral sclerite of the two lateral sclerites, closest to the tergite.
POSTEROANGULAR: (Latin, posterior = latter) behind the midline, caudal, angular = corner, for example: posteroangular setae = setae inserted on the posterior corners of a sclerite.
