Eurystylus sauteri : Zheng & Lin, 2003: 328 (diag.) (not Kirkaldy, 1902 ). Diagnosis. Recognized by its generally dark brown, less mottled dorsum; a pair of clear, ocellate spots on pronotum; dark scutellum with whitish lateral corners (except for darkened posterior tip); each femur creamy white (pale brown in dried specimens) with apical 1/3–1/4 darkened ( Fig. 2 A); and male endosoma with PL smooth, lacking spinules or teeth and TL sharply hooked ( Fig. 5 I–J). Total length 5.1–7.8 ( ♂ )/ 6.3–8.1 ( ♀ ); maximum width 2.4–3.0 ( ♂ )/ 2.9–3.3 ( ♀ ). Most similar to E. burmanicus ; distinguished by generally darker basic coloration, somewhat thicker antennal segment II, and scutellum lacking a yellow, mesal stripe (cf. Fig. 2 A, E). Final-instar nymph ( Fig. 2 B) recognized by its uniformly pale whitish green body; clearly darkened apical parts of antennal segments II–IV; laterally darkened pronotum with a pair of ocellate spots; and 4 or 5 pairs of ocellate spots on abdominal sterna. Biology. This common univoltine mirid is associated with various inflorescences ( Table 1 ) and most probably hibernates in the egg stage. In the western part of Japan mainislands and Taiwan , it frequently co-occurs with E. sauteri . The population in warm temperate and subtropical zones may have two or more generations per year, based on collection data. Material examined.
