Abstract

Tibelloides Mello-Leitão, 1939 currently comprises four species of Neotropical grass-dwelling spiders. Herein, we describe and illustrate Tibelloides castelo sp. nov. with few records from Brazil (Minas Gerais, Piauí, Rio de Janeiro), and Tibelloides juatuba sp. nov., with records from Brazil (Minas Gerais, Pará, Paraná, Rondônia) and Paraguay (San Pedro). These two new species differ from the previously described ones by having body and legs conspicuously longer and thinner, male pedipalp without retrolateral marginal conductor, and female genitalia with compound copulatory ducts tubular and elongated.
