Diagnosis: Bryocoropsis belongs to the Odoniella - complex and can be distinguished from other genera in this group by the following characters: coloration mostly brown, body oval (Fig. 8), ASII distinctly incrassate towards apex, with tip not swollen or only slightly swollen; ASIII–IV distinctly clavate (as in fig. 9F in Namyatova et al., in press); eyes stalked, distinctly directed laterally (as in Fig. 10H); pronotum and scutellum often with shallow tumescences (Fig. 11D); setae on pronotum very rare; long and flattened setae on hemelytron; scutellum distinctly swollen, not exceeding pronotum height, nor divided into lower and upper regions (as in Fig. 12A); spermathecal gland attached to right of midline (Fig. 18G, I).
