Rediagnosis. Recognized by its moderate size; dark reddish brown general coloration; almost linear antennal segment II that is weakly clavate; nearly straight metatibia; C-shaped endosoma with bifurcate median process (its shorter branch tiny, Fig. 11C ); sclerotized ring with a developed rim dorsally ( Fig. 12C ); and vestibular sclerite with a conical projection left-laterally ( Fig. 12D ).

Measurements. See Table 2.

Biology. This oak-inhabiting mirid is known to be associated mainly with deciduous Quercus species ( Kerzhner, 1988; Urayama et al., 2019) and assumed to have a univoltine life cycle. The adults were found from mid-June to late July in warm temperate climate zone.

Discussion. See discussion under P. erraticus .
