Comparative diagnosis. Body and eyes pigmented. Labrum with 6 supralabral setae; 24 labral setae. Mandibles with 11 rows of pectinate lamellae. P. ro s i n e i i has the internal branch of the gonopod similar those observed in the species P. t a bo a, P. leopoldoi, P. ambuatinga (Iniesta & Ferreira 2013 b), P. s pe l ae a (Iniesta & Ferreira 2013 a), P. rolamossa, P. gogo (Iniesta & Ferreira 2013 c), P. chaimowiczi, P. imbirensis, P. tocaiensis (Fontanetti 1996 a) and P. microzoporus (Mauriès 1987).

Description of adults. Measurements: Length from 58 up to 68 mm; maximum midbody diameter between 3.96 to 4.48 mm; body rings ranging between 62 to 65; length of antennae ranging from 4.4 to 4.7 mm (relation to diameter ranging 1.04 to 1.11); length of legs 3.52 to 4 mm (relation to diameter ranging 0.88 to 0.89); length of tarsal claw 0.24 to 0.32 mm (relation to diameter ranging 0.06 to 0.07). Color: Visualization after fixation in 70 % alcohol. Bicolor, with the anterior region of each ring darker and posterior brownish yellow. Head (Fig. 7 a): Head glabrous and pigmented. Labrum with a row containing 24 labral setae, and above a row with 6 supralabral setae. Mandibles slightly pigmented, with 2 external teeth, 4 internal teeth and 11 rows of pectinate lamellae. Eyes with 27–30 ocelli arranged in 4 rows. Antennae pigmented and densely setose. First antennomere small, second, fourth, fifth and sixth similar, being the last larger. Third antennomere largest. Presence of basiconic sensilla in latter edge of fifth and sixth antennomere. Gnatochilarium typical of the genus. Trunk: Body pigmented. Prozone dark and metazone brownish yellow. Lateral region of each ring with transverse striae. Telson, anal shield and anal valve pigmented. First male pair of legs (Fig. 7 b): Coxae (Cx) larger; densely setose; triangle-shaped. Prefemur (Prf) with shorter oral process parallel (P) to the coxae. P with bristles arranged on base and base width equal to the distal region. Gonopod (Fig. 7 c, d): Gonopod short, stout and sclerified. Coxae reduced; glabrous and adhered to basal region of gonopod. Basal section (Bs) with width little larger than half of length; basiconic bristles arranged in rows along the entire the base of gonopod. Shoulder (Sh) evident and rounded. Distal section (Ds) as long as wide and little smaller than half of length of Bs. Solenomere (S) trianguliform; distal region squamous, bifurcated, with an acute external tip and rounded internal with a seminal spine (Sp). Internal branch (Ib) starting right below the Sh line on Bs. Ib like a shield and bristles exceeding the S. Notes on the natural history and habitat. The species is also distributed in caves in the region of Pains (Fig. 15 a), though it was never recorded in sympatry with P. robsoni. However, P. ros i n ei i is less frequent, occurring in a few caves compared to P. robsoni. Their populations also tend to be small, which clearly demonstrates that populations of P. rosineii and P. robsoni also occur outside of caves, wherein the caves do not necessarily make up their main habitats. The caves where populations of P. ro s i n e i i were observed are small and generally dry, the main organic resource being guano of Desmodus rotundus.Published as part of Iniesta, Luiz Felipe Moretti & Ferreira, Rodrigo Lopes, 2014, New species of Pseudonannolene Silvestri, 1895 from Brazilian limestone caves with comments on the potential distribution of the genus in South America (Spirostreptida: Pseudonannolenidae), pp. 361-397 in Zootaxa 3846 (3) on pages 370-371, DOI: 10.11646/zootaxa.3846.3.3, http://zenodo.org/record/25010

Males of Abiliodesmus n.gen. differ from those of other Arthrosolaenomeridini genera by the combination of the following characters: slight dorsal lobe on leg prefemur (Figs 31C–D); lateral macrosetae dispersed on the gonocoxae, in mesal view (Fig. 32F); cingulum with a basal position (Fig. 20F); and presence of a membranous lateral flap at the apex of the solenomere (Fig. 22D) (absent in Abiliodesmus mapinguari n. sp.). Description. General characters: Body length between 34.63 mm (A. defensor comb. nov.) and 69.15 mm (A. mapinguari n. sp.). Coloration (specimens long preserved in 70% ethanol) variable between species, ranging from ocher to reddish brown, paranota tip and posterior border of the metaterga slightly whitish. Gnathochilarium: lingual plate covered completely by sparsely setae; mentum only centrally covered by setae, with smooth edges and stipes covered by sparsely setae. Body alignment of paranota in posterior view curved ventrally (straight in A. cataractae comb. nov and A. defensor comb. nov.). Sternite of the fourth segment with a pair of projections, sternite of the fifth with two pairs of projections covered by setae, the posterior pair less conspicuous. Sternite of sixth body ring without ventral projections (present in A. mapinguari n. sp.); seventh with a pair of ventral projections (absent in A. cataractae comb. nov.) and post-gonopodal sternites with two pairs of acuminate ventral projections (Fig. 30F) (absent in A. cataractae comb. nov. and rounded in A. mapinguari n. sp.). Paranota form: round to slightly rectangular (Figs 20B, 23B).

Male characters: Leg pair of the third body ring with the coxae presenting the rectangular genital papilla. Gonopod aperture on seventh body ring with the posterior margin excavated and with a small projection (absent in A. mapinguari n. sp.). Gonopods: gonocoxae equivalent to about half the length of the telopodite, cylindrical, without a spiniform process. Prefemoral process: elongate and thin with a dorso-basal process (Fig. 20D). Cingulum in a basal position (Fig. 20F). Solenomere long with apex ascending and lateral membranous expansion (Fig. 21D) (absent in A. mapinguari n. sp.). Female characters: Vulvae (Figs 24E–F): oval-shaped, having different proportions in lateral view. Distribution. States of Tocantins, Goiás and São Paulo, Brazil (Fig. 25). Etymology. The genus name is taken as a noun in apposition. Name in honor of a very important person in the life of the first author, considered a great storyteller, with the combining stem “-desmus,” meaning band, commonly used in generic names in Polydesmida.

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).

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.
