scientific name    Megalothrips    



Species in this genus are usually large and black (Stannard, 1957). The head is longer than wide, arched dorsally and is striated transversely. The eyes appear to be small compared to the head, and ocelli are present. The interocellar, postocellar and postocular setae are all well developed. The antennae are 8 segmented with segments 6 and 7 produced ventrally at the apex. Antennal segment 8 is lanceolate. The maxillary stylets are long and retract to the eyes when they are drawn into the head. The prothorax is short and the thoracic setae are well developed with the posterior pairs being the longest. The epimeral sutures are incomplete and the basantra is present. The fore tarsi may be armed with a small tooth, or the tarsi may be un-armed. The pelta has two lateral portions and a middle portion that are connected with a slender "bridge". The anterior halves of the abdominal tergites are hexagonally reticulate, while the rear portion of each tergite is transversely striated. The wing holding setae on the abdominal tergites are well developed. In males, abdominal tergite 6 has a pair of tubular lateral processes. The tube is hairy, long and bowed. The tube is longer in females and shorter in males (Stannard, 1968).
