Herrich-Schaeffer’s (1840) record from Brasil is apparently a mistake. The record of Dymantis plana from Tanzania (Gerstaecker 1873) apparently represents a misidentification, most probably of D. relata.
Nonnaizab (1995) listed Dymantis plana from China (Inner Mongolia, Xinjiang, Qinghai), as well as from Mongolia and ‘the former Soviet Union’. The provided redescription, habitus and paramere drawing appears to us to be identical with Phaeocoris ellipticus (Herrich-Schaeffer, 1840) as illustrated by Ahmad et al. (1996, as Lodosia gonocoxa) and Gapon & Baena (2005), who figured the paramere from nearly the same aspect. The illustrations from both of the above papers fit well with the drawings by Nonnaizab (1990). Later, Nonnaizab et al. (1988) and Nonnaizab (1999) listed Dymantis elliptica (Herrich-Schaeffer) from Inner Mongolia, which is a species recently reinstated in the genus Phaeocoris (see Gapon & Baena 2005), which leaves no doubt about the record of D. plana by Nonnaizab (1995) is a misidentification of that species.
