scientific name    Parthenothrips    

Pantropical. On the leaves of indoor ornamental plants in temperate regions (Mound and Kibby, 1998).


The head is narrowed at the base, and strongly reticulate dorsally. The eyes are large and protruding, and the ocelli are in a close triangle. Antennae are 7 segmented, and segments 3 to 7 are long and slender, with a threadlike seventh segment. Antennal segments 3 and 4 with simple sense cones. The mouth cone is broadly rounded and is of moderate size. The prothorax is reticulate, the setae are broad, and the anteromarginal and anterolateral pairs are the longest. The meso and metascutum are reticulate, and the metascutum lacks a raised V-shaped region. The mesospinasternum is fused to the metasternum, and the tarsi are 1 segmented. Members of this genus are macropterous, with broad forewings that are indented after the basal third, and are mildly reticulate. The forewings lack bristle-like setae along the leading edge. Abdominal tergite 1 has a prominent median line, and most tergites have weak hexagonal reticulations on the anteromedian and lateral areas. Abdominal tergite 8 lacks a comb of setae, and males have a single round to oval glandular area on each of sternites 4 to 7 (Stannard, 1968).
