Pagaronia spinosa Hori, 1994: 156 , figs. 8–14.

Taxonomic note. This leafhopper had been known from four localities in Aichi Prefecture, and it was previously reported that the fuscous marking of the fore wing is sometimes obscure ( Hori, 1994). Through our research, eleven localities in three prefectures are newly recorded, and some variations in the shape of male genitalia are recognizable. This species is unique in the structure of the male genitalia. The inner pygofer process is very long and the short ventral branch is forked near the base of the process. The shaft of the aedeagus is slender and has a very long spine-like ventral projection ( Figs. 55, 56 ). Two males collected from northeasternmost localities, Bungui Pass and Ôkawara, are slightly different from the others in the pygofer lobe and inner pygofer process; the pygofer lobe is shorter and wider; the inner process has no ventral branch and is directed dorsally ( Fig. 57 ).

Body length (mean). ď, 8.5–9.5 mm (8.8 mm); Ψ, 9.0– 9.6 mm (9.4 mm).
