Description. Coloration (specimen preserved in 70% ethanol). As in P. painensis sp. nov.

Body length. Male. 3.9–4.3 mm (n=4).

Head. Vertex ( Fig. 74A, C ): approximately 2.0 times wider (0.4) than long (0.2); apical compartment, moderately large, approx. 3.0 times wider (0.3) than medially long (0.1); apical transverse carina (0.319) smaller than the subapical carina (0.354); angled formed by caudal margin well triangular, slightly concave laterally. Frons ( Fig. 74B ): 1.8 times longer (1.1) than wide (0.6), and approx. 2.0 times wider medially than apically (0.3). Frontoclypeal suture slightly concave and weakly bent upwards.Anteclypeus ( Fig. 74B ): with median carina moderately developed; Postclypeus ( Fig. 74B ): with median carina moderately developed. Rostrum in ventral view surpassing slightly the base of the abdomen.

Thorax. Pronotum ( Figs. 74A, C ): submedian carinae weakly developed, slightly evanescent and irregular behind the eyes; hind margin obtuse, sometimes obtusely angled. Mesonotum ( Fig. 74A ): median carina well developed, evanescent or sometimes absent distally; lateral carinae moderately developed. Tegmina (Forewings) ( Fig. 74D ): length 6.1 mm, hyaline with brown spots, two curved spots in pcc, two also curved spots of increasing size between fork A1/A2 and SCP+R, one inconspicuous spot in the post nodal region between RP1 and MP1.1, transversal sloping spot in the center of the tegmina connecting the SCP+RA fork and the posterior cubital area; rm-1 occurring together the first fork MP; mcu-1 occurring distally of the first MP fork; simple tubercles in all veins more visible on the A1/A2 fork; petiole in RP2.2+RP2.3 weakly developed; 12 apical cells; with 7 subapical cells, rarely 8 in one of the tegmina ( Fig. 74D ).

Posterior leg. Hind tibia ( Figs. 74E ): approximately 2.1 mm; with 4 spines laterally, the first at the base of the tibia being very small. 1 st tarsomere ( Figs. 74F ): 7 apical teeth, approx. the same size, but two in the middle slightly larger. 2 nd tarsomere ( Figs. 74F ): 8 apical teeth, the two external ones slightly large (one larger) and the middle ones gradually smaller; 3 large platellae one separated by apical teeth without platellae.

Male terminalia. Pygofer ( Figs. 74A–C, G ): bilaterally symmetric; in lateral view, dorsocaudal margin without process; caudal margin large and straight; in ventral view, ventromedian process triangular, longer than wide. Anal tube ( Figs. 74A–C, G ; 75A–C ): tubular, distally moderately short and bent at approx. 45°; in dorsal view, moderately narrow near base, and wider distally; in lateral view that wide at base as distally; distal region small and slightly asymmetric; in ventral view, distal margin slightly concave and smaller than lateral margins; epiproct and paraproct short. Genital styles ( Figs. 74A–B, G ; 75D–F ): in lateral view, weakly wider apically and narrow near the base; ventral margin straight, slightly concave above the bent medially; dorsocaudal margin convex apically; dorsal margin with a weakly expanded region occurring above the bent medially. Aedeagus ( Figs. 74E–F ; 75G–I ): asymmetric tubular, with six spines, two movables (a, d). Shaft of the aedeagus with four spines; in right lateral view occurs three spines, 1 st spine well long and curved (a), inserting on the apical region of the shaft reaching the base; 2 nd spine moderately long (b) occurs almost apically; 3 rd spine slightly smaller (c), occurs almost de middle of the shaft; in left lateral view, 4 th spine moderatelly long (d), occurs almost apically on the shaft. Flagellum with two spines, all on the right margin; 5 th spine small (e), occurs at the base of the flagellum; 6 th spine slightly larger and curved (f), occurs on the apical region of the flagellum.

Etymology. The specific epithet muiri is a tribute to British hemipterist Frederick Muir, who made major contributions to the genus Pintalia Stål, 1862 .

Diagnosis. Pintalia muiri sp. nov. can be distinguished from other species of the genus Pintalia by presenting a very long spine at the apex of the aedeagal shaft almost reaching the base, and just below it with two non-movable spines with close origins but in opposite directions. In addition, the distal region of the anal tube is moderately short and bent at approx. 45°.

Distribution. BRA, MG; Dores de Guanhães municiapllty G. Energia Cave-SPT002 ( Type Locality), and São Sebastião do Maranhão municipality.

Remarks. The holotype exhibits right tegmina with MP1bifid (MP1.1 and MP1.2) and MP3+4 trifid (MP2, MP3 + MP4) as Fig. 74D . The spine (d) was broken in many specimens, as in figure 74 - F, in a few specimens it was found complete as in figure 75 - I.
