The monophyly of the North and South American endemic subtribe Blapstinina (Tenebrionidae: Opatrini) is tested through phylogenetic analyses using five molecular markers [nuclear ribosomal 28S (28S), cytochrome oxidase subunit II (COII), arginine kinase (ArgK), carbamoyl‐phosphate synthetase domain of rudimentary (CAD), wingless ( wg )]. Representatives of several opatrinoid subtribes were taken into consideration, including other geographically overlapping endemic genera, namely Ammodonus , Ephalus and Pseudephalus (all previously considered representatives of Ammobiina). A comparative study of morphology was performed to assess resulting phylogenetic hypotheses. Analyses support the monophyly of Blapstinina; however, they also strongly indicate that Ammodonus should be included within the subtribe. Mecysmus is nested within Blapstinus and therefore, a new synonymy, Blapstinus (= Mecysmus syn.n. ), and the following combinations are introduced: Blapstinus advena comb.n. , B. angustus comb.r. , B. laticollis comb.n. , B. parvulus comb.n. , B. tenuis comb.n. Morphological analysis showed a close affiliation between Ephalus and Pseudephalus . Based on these results, Pseudephalus is synonymized with Ephalus [ Ephalus (=  Pseudephalus syn.n. )], and the following combination is introduced: Ephalus brevicornis comb.n. Recovered topologies also strongly support transferring Ephalus stat.n. into Opatrina, making the distribution of Opatrina amphi‐Atlantic.
