May, 1968 Stannakd: Th 249 KEY TO FAMILIES OF TEREBRANTIA (Illinois and neighboring states) Antennae nine segmented with sensoria of segments III and IV each placed longi- tudinally; fore wings broad and rounded at tips; ovipositor of female upturned Aeolothripidae Antennae six, seven, eight, or nine seg- mented with sensoria either protruding as forked or simple sense cones or as flat areas encircling apex of each of these segments; fore wings generally narrower and usually pointed at tips; ovipositor of female downturned 2 Sensoria of antennal segments III and IV each protruding as a single or forked sense cone; cocoon-breaking hooks lacking on fore tarsi Thripidae Sensoria of antennal segments III and IV encircling apex of each segment, flat, not protruding as a cone; cocoon-break- ing hooks present (Fig. 76-78) or ab- sent (Fig. 79) on fore tarsi 3 Light yellowish brown thrips; antennae each eight segmented, segments III and IV with apical sensorial areas as single, large sensoria (Fig. 64); ovipos- itor of female weakly developed Merothripidae Dark brown thrips; antennae each nine segmented, segments III and IV with circumpolar sensorial areas composed of numerous small circular sensoria (Fig. 65); ovipositor of female strongly developed Heterothripidae. AEOLOTHRIPIDAE Uzel (1895) These primitive thrips may be dis- tinguished from all others in Illinois by the combination of relatively broad wings (when present), upturned ovi- positor of the female, nine-segmented antennae, and elongate oval or longi- tudinal sensoria on antennal segments III and IV. As do those in the Hetero- thripidae, members of this family bear cocoon-breaking hooks on the fore tarsi. Only two genera occur in our state, Aeolothrips and Stomatothrips. About a half dozen more genera are found in the southern and western regions of North America, still other genera oc- cur elsewhere in the world, and even some fossil representatives are k
