Ortega, Diego Ribeiro Migueis, Nagahama, Roberto Hiroaki, Motta, Paulo Cesar & Bertani, Rogerio, 2013, Three new species of Fufius Simon, 1888 (Araneae, Cyrtaucheniidae) from Brazil with the redescription of Fufius funebris Vellard, 1924 and description of the female of Fufius lucasae Guadanucci & Indicatti, 2004, ZooKeys 352, pp. 93-116 : 104-107

Fufius jalapensis sp. n. Figs 37-43, 45

Diagnosis.

Male differs from those of all other species by tibia I lacking spines (Figs 39-41) and the presence of several spines (ca. 11) on the prolateral patella III. The female is unknown.

Etymology.

The specific name, jalapensis, refers to the type locality, “Jalapão”, a state park in the eastern state of Tocantins, Brazil.
