Comments. Aacanthocnema banksiae (Froggatt) is hereby returned to the genus Trioza . Froggatt's (1901) description and illustration of the nymph, the colour, wing shape and alignment of the body of the adult at rest closely resemble many other species of Trioza (see Trioza sp. from Myoporum insulare, Morgan 1984 , pl. 22 figs 2, 7) in which the wings are hyaline, wing apex is subangular, medial and cubital cells are characteristically shaped and the female proctiger and subgenital plate are more elongate with pointed apices. These characters differ from both Aacanthocnema and Acanthocasuarina in which the nymphs are heavily-sclerotised, alignment of body of adults at rest lie parallel to its substrate, wings appear less glassy, wing apices are rounded, medial and cubital cells are distinct, and proctiger and subgenital plate are short, rounded or proctiger has an apical hook. It is noted that wing shape and apparent lack of hind tibial spurs may have been the diagnostic characters which led to the tentative placement of the species in Aacanthocnema by Tuthill and Taylor (1955). However, close examination of the unique male slide specimen shows that the wing apex is subangular (although partly obscured by folding) and the hind tibia has 1 outer and 2 inner sclerotised spurs (athough barely visible). Based on these characters, this species is hereby returned to Trioza .
