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 history[]
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).
