Thaumatothrips froggatti Karny, 1922: 268

The macropterous and micropterous females of this species are strikingly different in appearance. The major setae on the head and pronotum are long and whip-like in micropterae, whereas they are shorter and capitate in macropterae. Moreover, female macropterae vary greatly in size, with small females having the head much less elongate. These variations were illustrated by Mound and Crespi (1992). This thrips has been found in the galls induced by the two different species of Iotatubothrips from eastern and western Australia. In eastern Australia, large colonies have been found in the woody galls of Iotatubothrips crozieri on Casuarina cristata at sites between Dalby and Goondiwindi in southern Queensland, also across inland New South Wales to Broken Hill. Specimens have also been seen labelled as collected by Froggatt in 1928 at Euston on the River Murray. In Western Australia, large colonies were found in the woody galls induced by Iotatubothrips kranzae on Casuarina obesa trees at the Murchison River crossing, 90km north of Geraldton.
