Eotapinoma and Chronomyrmex, from Canadian Campanian amber (79-78 Ma), are the only dolichoderines known from the Cretaceous. They were originally placed in the Tapinomini and Leptomyrmecini, respectively, but are now treated as stem-group dolichoderines (Dlussky, 1999; McKellar et al., 2013; Boudinot et al., 2016; Perrichot et al., 2019).
