Lacronia is a genus of Pachylinae (Arachnida, Opiliones, Gonyleptidae), which includes four Brazilian species. A striking diagnostic character is the trochanter IV of male with strong medial prolateral apophysis forming a pincer with the dorso-apical apophysis of coxa IV. Two of these species present neon green stripes on the mesotergum (Kury, 2003b), which is uncommon in this subfamily.

Taxonomic historyEdit

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).
