Gelanor Thorell, 1969 comprises 11 Neotropical species. In this paper, two new species are described from Bra- zil: Gelanor hoga sp. nov., based on males and females from the state of Amazonas, and Gelanor cachimbo sp. nov., based on males from the state of Pará. Additionally, new records from Brazil are provided for Gelanor altithorax Keyserling, 1893, Gelanor consequus O. P.-Cambridge, 1902, Gelanor juruti Benavides & Hormiga, 2016, Gelanor latus (Keyserling, 1881), Gelanor waorani Benavides & Hormiga, 2016 and Gelanor zonatus (C.L. Koch, 1845) and a key to the Brazilian species and illustrations are provided. [ABSTRACT FROM AUTHOR]

Species of Falsocis are very distinct from members of other ciid genera and are relatively uniform morphologically. The genus has been recorded only from well preserved forests in the Neotropical region, from Costa Rica to southern Brazil. We describe Falsocis sooretama sp. nov. based on adult individuals collected at Reserva Biológica de Sooretama (Sooretama, state of Espírito Santo), a conservation unit of the Atlantic Forest biome. Falsocis sooretama sp. nov. is closely related to F. occultus Lopes-Andrade & Lawrence, but differs from it in possessing sparser stout bristles and very minute setae (~0.01 mm) on elytra, and apex of anterior male pronotal plate rounded rather than acute. The male genitalia of F. sooretama sp. nov. and F. occultus are conspicuously different: in the former the penis is enlarged at apex and the apical lobes of tegmen are not emarginated (each lobe has only a small excavation in the outer edge). Individuals of F. sooretama sp. nov. were found inside the basidiomes of an unidentified species of Hymenochaetaceae, possibly belonging to Phellinus. We also provide additional geographic records and an updated identification key to all Falsocis species. [ABSTRACT FROM AUTHOR]

Dubiaranea argenteovittata Mello-Leitão, 1943 was described from the state of Rio Grande do Sul, Brazil, based on a female. We describe and illustrate the male of the species for the first time, and provide the first records for the states of Santa Catarina and Paraná. The redescription and illustrations of the female is based on the holotype and new material from the type locality. New distributional records are also provided for the state of Rio Grande do Sul.
