This genus was at first called Luederwaldtia Mello-Leitão, 1923, but the name was already preoccupied, being a junior homonym of Luederwaldtia Schmidt, 1922 (Hemiptera). Strand (1942) proposed the valid replacement name Lacronia, which was ignored by most subsequent authors and unearthed only 60 years later (Kury, 2003a).
