Type species. Folcloredesmus thomasi n. sp.

Diagnosis. Males of Folcloredesmus n. gen. differ from those of other Arthrosolaenomeridini genera by the combination of the following characters: paranota sub-triangular (Fig. 26B); slight dorsal lobe on leg prefemur; presence of a spiniform process in gonocoxae (Figs 26D, 32C).

Description. General characters: Coloration (specimen long preserved in 70% ethanol) ocher with the paranota tip slightly whitish. Gnathochilarium: lingual plate covered by several setae; mentum only centrally covered by setae, with smooth edges and stipes completely covered by sparse setae. Body rings: cuticle slightly rough; alignment of paranota in posterior view straight. Sternite of the fourth segment with a pair of projections, sternite of the fifth segment with two pairs of projections covered with setae and sternite of sixth body ring with two pairs of ventral projections; seventh body ring with a pair of projections and post-gonopodal sternites with two pairs of rounded ventral projections (Fig. 30D). Paranota form: sub-triangular (Fig. 26B). Legs: slight dorsal lobe, a ventroapical projection in the prefemur of the anterior legs (Fig. 31E), and presence of granules in the tibia and tarsus; thin setae on the ventral part of the podomeres in the anterior legs (Fig. 31F).

Male characters: Gonopod aperture on seventh body ring with the posterior margin excavated, concave and transverse sulci; without projections. Gonopods: gonocoxae equivalent to about half the length of the telopodite, cylindrical, with a spiniform process (Fig. 26D). Prefemoral process: elongate and thin (Fig. 26D) and with indentations in the apical portion, in ectal view (Fig. 34B). Cingulum in medial position (Fig. 26F). Solenomere also long and thin with apex slightly curved (Figs 26D–F).

Female characters: Vulvae: oval-shaped, sub-triangular in lateral view.

Distribution. State of Mato Grosso (Fig. 28).

Etymology. The genus name comes from the Portuguese word for “Folclore” (culture shared by a particular group of people, as the tales characters used as species epithet in this paper) with the combining stem “-desmus”, commonly used in generic names in Polydesmida .

Composition. One species: Folcloredesmus thomasi n. sp.
