The species Brachylibitia ectroxantha was described by Mello-Leitão in 1941 and since then it was never again reported or studied. Its type is certainly lost and his identity was until now a mystery; it is currently considered as species inquirenda and transferred to Eulibitia in a recent revision of the genus. Herein, we designate a neotype and provide a redescription of the species based on fresh material from Belén (Boyacá, Colombia) 50km SW from the type locality, across the Chicamocha River. The species is recognizable by the blot pattern of the ladder mask of the dorsal scutum, the absence of groin warts in coxa IV and of armature in some areas of the mesotergum. Additional data about the genus is offered, and the species Cynortaambigua is herein recognized as a junior synonym of Eulibitia scalaris, involving the synonymy of the genus Sphalerocynorta Mello-Leitão, 1933., (Copyright © 2019 Académie des sciences.

Usatama gen. nov. is described to include a new species of Kimulidae from Colombia. This is the first record of the family from the country. The new genus presents a weakly armed ocularium, feeble sexual dimorphism, and unique genital structure with three parallel horseshoe-shaped girdles in pars distalis and absence of cochleariform macrosetae., (Copyright © 2019 Académie des sciences.

Discocyrtoidespinorum sp. nov. is described from the conifers forest in Paraná State, Southern Brazil. This is the second species of Discocyrtoides Mello-Leitão, 1923, the other being known from São Paulo State. It is remarkable for having greenish/yellowish spots in the dorsal scutum highly contrasting with the brown background, a feature rare in Mitobatinae, hitherto known only for Ruschia Mello-Leitão, 1940. It is the first record of this genus for Paraná State (WWF Ecoregion NT0101, Araucaria moist forests). Terminology for the male genitalia of the Mitobatinae is defined and illustrated., (Copyright © 2019 Académie des sciences. Published by Elsevier Masson SAS. All rights reserved.)

Discocyrtanus canjinjim sp. n., belonging to the family Gonyleptidae Sundevall, 1833 is described based on nineteen specimens, eleven adult males and eight adult females, collected in the Vila Bela da Santíssima Trindade, in the State of Mato Grosso, Brazil. This new species represents an endemic component for the harvestmen fauna of Chiquitano Dry Forests terrestrial eco-region, being the most occidental point of distribution of the genus, notably found in the Cerrado and the Atlantic Forest. The new species is characterized by femur IV swollen with the same length of dorsal scutum, trochanter IV with prodorsal distal apophysis as a stout hook not bifurcated, and a unique form of genitalia in the genus. This paper also includes the first identification key to the species of the genus after its revalidation., (Copyright © 2017 Académie des sciences. Published by Elsevier Masson SAS.
