( Figs. 68 A–F ; 69 A–G ; 70 A–I ; 71 A–D ; 72 )

Type material. Holotype: Male Brazil, MG: Montalvânia municipality, Fosséis Cave ( UTM 573822 W, 8417268N, 23K), 28.xi.2016, (Ferreira R.L), ( ISLA 75691 ) . Holotype condition: not dissected, stored in an individual vial in ethanol 70%. Paratypes. Same data as male holotype, except for 1♀ ( ISLA 100977 ) ; 2♂, 1♀ and 2 nymph’s ( ISLA 100978 ) .

Description. Coloration (preserved specimen): As on the P. dorensis sp. nov.

Body length. Male. 4.0– 4.5 mm (n=3). Female. 5.4–5.8 mm (n=2).

Head. Vertex ( Fig. 68A, C ): approximately 1.6 times wider (0.5) than long (0.3); apical compartment moderately large, approx. 3.0 times wider (0.3) than medially long (0.1); apical transverse carina (0.316) smaller than the subapical carina (0.360); angle formed by caudal margin, triangular, moderately concave medially. Frons ( Fig. 68B ): 1.5 times longer (1.2) than wide (0.8), and approx. 2.6 times wider medially than apically (0.3). Frontoclypeal suture, moderately bent upwards medially, straight laterally. Anteclypeus ( Fig. 68B ): median carina well developed; Postclypeus ( Fig. 68B ): median carina moderately developed. Rostrum in ventral view surpassing slightly the base of the abdomen.

Thorax. Pronotum ( Fig. 68A, C ): submedian carinae developed but slightly irregular and evanescent behind the eyes; hind margin obtusely angled. Mesonotum ( Fig. 68A ): median carina well developed, but evanescent or absent distally; lateral carinae well developed. Tegmina (Forewings) ( Fig. 68D ): length 7.2 mm; hyaline with brown spots, two curved spots in pcc, three also curved spots of increasing size between fork A1/A2 and SCP+R, the two near fork A1/A2 connected, four rounded spot in the post nodal region between RP1 and MP4, the spot in RP region larger, the transversal sloping spot weakly developed in the center of the tegmina connecting the SCP+RA fork and the posterior cubital area; rm-1 and mcu-1 occurring distally of the first MP fork; simple tubercles in all veins, slightly more visible on the A1/A2 fork; with punctual anastomosis in RP2.2+RP2.3; 12 apical cells; 7 subapical cells.

Posterior leg. Hind tibia ( Fig. 68E ): approximately 2.4 mm; with 4 spines laterally, the first at the base of the tarsomere being very small. 1 st tarsomere ( Fig. 68F ): 7 apical teeth, approx. the same size, two in the middle slightly larger. 2 nd tarsomere ( Fig. 68F ): 8 apical teeth, two external ones slightly large (one larger) and the middle ones gradually smaller; 1-2 platellae.

Male terminalia. Pygofer ( Figs. 69A–C, G ): bilaterally symmetric; in lateral view, dorsocaudal margin without process; dorsal margin large; caudal margin, straight; in ventral view, ventromedian process triangular, wider than tall. Anal tube ( Figs. 69A–C, G ; 70A–C ): tubular and distally developed, bent in 90°approx; in dorsal view weakly narrow near base and wide distally; in lateral view slightly with small convexity near to the base; distal region moderately large and asymmetric large, slightly larger on left lateral than the right lateral; in ventral view, with distal margin well concave; epiproct and paraproct short. Genital styles ( Figs. 69A–B, G ; 70D–F ): in lateral view, moderately wider apically and narrow near the base; ventral margin straight; dorsocaudal margin convex apically; dorsal margin with a moderately triangular region occurring above the bent medially. Aedeagus ( Figs. 69D–F ; 70G–I ): asymmetric tubular, with seven spines, only one movable (c). Shaft of the aedeagus with three spines; in right lateral view with two small spines, 1 st spine small (a), inserted on the apex of the aedeagal shaft towards the ventral region; 2 nd spine smaller and no movable (b), occurs near the center of the shaft; in left lateral view, 3 rd spine movable, long and curved (c), occurs in the apex of the shaft. Flagellum with four spines, all on the right margin; 4 th spine small (d), occurs at the base of the flagellum; on the apical region of the flagellum occurs three spines, 5 th and 6 th large spines occur together (e)(f); 7 th spine small (g), occurs slightly above on the apical region.

Female terminalia. Anal tube ( Figs. 71A, C ): long; in lateral with lateral margin weakly developed; in dorsal view, slightly rounded; epiproct and paraproct flattened dorsoventrally; in dorsal view, paraproct very small and rounded. Gonocoxae VIII ( Figs. 71A–B ). Ovipositor ( Figs. 71A–B ): in lateral view, sabre-shaped, curved upwards dorsally, strongly surpassing the anal tube.

Etymology. The specific epithet montalvaniensis refers to the type locality, municipality of Montalvânia (MG).

Diagnosis. Pintalia montalvaniensis sp. nov. can be distinguished from other species of the genus Pintalia by the three spines at the apex of the antennal flagellum, the middle being larger and more robust, and by exhibiting a single long and movable spine on the left side of the aedeagal shaft.

Distribution. BRA, MG; Montalvânia municipality, Fosséis cave (Type Locality).
