Center, 39.747, 141.133 ( Quercus dentata ).

Rediagnosis. Recognized by its comparatively large size; distinctly setose pronotum and hemelytron with dark, stiff, upright setae ( Fig. 5F View FIGURE 5 ); almost straight, rather wide and nearly continuous median band of scale-like setae; bulbous right paramere ( Figs 11H View FIGURE 11 , 18N View FIGURE 18 ); rather developed apical ridge of endosoma; and uniformly distributed spinules on interramal lobe ( Fig. 19M View FIGURE 19 ).

Biology. This univoltine mirid is commonly found on a variety of deciduous trees and herbs (see above) in northern part (cold temperate climate zone) of Japan.

Discussion. A dorsal habitus image and illustrations of the male genitalia provided by Schuh (1984, figs. 177, 192–198) doubtlessly correspond to P. miyamotoi ( Figs 6A View FIGURE 6 , 9O View FIGURE 9 , 14 View FIGURE 14 P–Q); the figures were based on specimens collected by Illingworth (date not provided) from Yokohama, Japan where thermophilic evergreen broadleaf forests dominate and P. setulosus in all likelihood does not occur. Contrastingly, P. miyamotoi is a specialist of pines ( Pinus densiflora , P. koraiensis and P. thunbergii ). The Yokohama specimens are assumed to have been collected in early 20th century as the collector Illingworth visited this famous port city in June and July, 1923 ( Illingworth, 1926). These Pinus species, breeding hosts of P. miyamotoi , have traditionally been preferred in Japan and were abundantly planted also in Yokohama in early 20th century (cf. Nagasaki University Library, 2002 –2006).
