|scientific name Stictothrips |
It is thought that members of this genus live on dead branches or twigs (Mound and Marullo, 1996).
The head is broad, and the cheeks have a few short, pale setae that are expanded apically. The antennae are 8 segmented. Antennal segment 3 has 1 sense cone, segment 4 has 2 sense cones and segment 8 is constricted at the base. The body has a granulate sculpture. The maxillary stylets retract deeply into the head, and in this position are about, one-fifth of the width of the head apart. A maxillary bridge is present. The major setae on the prothorax are short, expanded and pale and the epimeral sutures are weak. The mesonotum is divided longitudinally and the metanotum has several pairs of medial setae. Each fore tarsus has a tooth. The forewings are swollen near the base, have an angulate constriction (Mound and Marullo, 1996), and are hexagonally reticulated (Stannard, 1957). Wing holding setae are present and flattened. The setae on tergite 9 are short and males lack a glandular area (Mound and Marullo, 1996).
Members of this genus are present in Alberta, B. C. (Chiasson, 1986), Africa, India, and the U.S. (Mound and Marullo, 1996).
