Type species: Tarus zargoides Wollaston, 1863 by monotypy. Etymology. From the generic name Tarus [ q.v .] and the Latin suffix - ulus (small, little) [masculine]. Diversity. Twenty-one species in North America (16 species, one of them Holarctic), Mexico (two species shared with North America), Eurasia (two species, one endemic to eastern Asia), and North Africa (four endemic species). Identification. Lindroth (1969a) reviewed all North American species. Since then, one Palaearctic species ( Coptodera vaporariorum ) has been found to occur naturally also in North America. Shpeley and Ball (1999: 420-421) published an emendation to Lindroth's (1969a: 1072-1073) key of Cymindis to incorporate Coptodera vaporariorum and commented on the structural differences to separate that species from Coptodera unicolor which is most similar externally. Taxonomic Note. Lorenz (2005) listed all Nearctic species in the subgenus Cymindis s.str. However, Lindroth (1969a: 1070) noted that the North American species belong to the subgenus Tarulus , to which Coptodera vaporariorum is included.
