Brachychthonius Berlese, 1910, pp. 218, 219.
Brachychochthonius Jacot, 1938b, p. 130.
Berlese (1910) designated Hypochthonius brevis Michael as the type of the genus Brachychthonius . The generic diagnosis is, however, accompanied by a figure of the type species, which unmistakably defines it as strongly and different from Hypochthonius brevis Michael ; for this reason Willmann (1928a, p. 160, fig. 11) correctly created a new specific name ( B. berlesei ) for B. brevis Berlese (non Michael). Most authors still mentioned, however, Hypochthonius brevis Michael as type of the genus; Jacot (1938b, p. 130) even created a separate genus Brachychochthonius (type: B. jugatus Jacot , 1938b), which included B. berlesei . Recently, however, some authors expressed as their opinion that properly Brachychochthonius is to be considered a synonym of Brachychthonius . In the present paper I use indeed the name Brachychthonius in this correct sense.
