Key to Eurystylus  and four assumed related genera in Asia

1. Frons with a pair of fuscous, velvety spots along inner margins of eyes; antennal segment I distinctly flattened; pronotal collar thicker than base of antennal segment II; basal margin of scutellum shorter than lateral margin................ Eurystylus 

- Frons without such spot; antennal segment I cylindrical, not flattened; collar as thick as or narrower than base of antennal segment II; scutellum forming nearly equilateral triangle......................................................2

2. Antennal segment II shorter than basal width of pronotum; abdomen wider than hemelytron, with lateral margins of sterna partly visible in dorsal view................................................................. Heteropantilius 

- Antennal segment II as long as or longer than basal width of pronotum; abdomen narrower than hemelytron..............3

3. Basic coloration of body pale brown, partly tinged with red, or sometimes uniformly creamy white; labium long, reaching metacoxa................................................................................... Eocalocoris 

- Basic coloration brick-red, dark reddish brown to fuscous; pronotum and scutellum often with darker longitudinal stripes; labium short, not exceeding middle of mesocoxa.............................................................4

4. Body smaller, less than 7.0 mm (body length 8.0 mm in continental Chinese Ep. hirtipes Zheng & Liu  ); scutellum more or less tumid ( Fig. 9View FIGURE 9 A –B) or sometimes strongly inflated medially ( Fig. 9View FIGURE 9 C –E)................................ Eurystylopsis 

- Body larger, more than 8.5 mm; scutellum almost flat................................................. Miyamotoa
