Tlle sexual dimorphism in the nymphal stages of Tingidae was observed by means of a scanning electron microscope on the basis of 9 Japanese species. The following nlorphological differences between male and female nymplls are externally recognizable on the 8th and 9th sternites of tlle 4th (excepting Cysteochilafieberi observed only on the 5th instar nymphs) and 5th instar nymphs of each species. In the female, the hind margin of the 8th sternite is distinctly projected posteriorly forming an arched sclerite. The lateral sides of the convexity of the 9th sternite are straight and convergent posteriorly, so as to form a V-shaped sclerite. A series bfvery minute holes are arranged in a row along the median line of the 9th sternite. The 9tll sternite of the 5th instar nymph is provided witll a small bifurcate (W-shaped) projection on its postero-central margin. In the male, the hind margin of the 8th sternite is not projected posteriorly. The converged lateral sides of the convexity of the 9th sternite are outwardly curved, so that it forms a U-shaped sclerite. The 9th sternite is provided with a minute hole near the posterior end of its median line, and with three to eleven minute processes around the minLrte hole.
