A new genus of huntsman spiders from the Neotropical region (Araneae: Sparassidae: Heteropodinae)

Guadana gen. nov. is proposed to include six new species: Guadana manauara sp. nov., G. urucu sp. nov. and G. neblina sp. nov. from Brazil; G. quillu sp. nov., from Ecuador; and G. panguana sp. nov. and G. tambopata sp. nov. from Peru. The genus is distinguished from the remaining Neotropical Sparassidae by the presence of a single row of intermarginal denticles, occupying most of the cheliceral grove, a sickle-shaped dorsal tegular projection in the male palps and epigynal ledges in the female epigynum. It is placed in the subfamily Heteropodinae Thorell due to the presence of intermarginal denticles in the chelicerae, a long toothed female pedipalp claw, a ventral tibial apophysis and a ventral branch in the RTA of the male palps.
