Tropacarus Ewing, 1917
Tropacarus Ewing, 1917, p. 130.
Calhoplophora Berlese, 1923, p. 257.
Calhoplophora Berlese (1923) has the same type ( Hoplophora carinata C. L. Koch) as Tropacarus Ewing (1917); for this reason it must be placed in the synonymy of the last-mentioned genus. Ewing did not know Tropacarus carinatus, but founded his generic diagnosis on the descriptions of the species. Ewing and Berlese nientioned no other representatives of the genus; I added Hoplophora pulcherrima Berlese, and Phthiracarus (Trachyhoplophora) brevipilus Berlese .
