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

Body length. Male. 4.0– 4.8 mm (n=5). Female. 5.0– 5.1 mm (n=2).

Head. Vertex ( Fig. 63A, C ): approximately 1.3 times wider (0.4) than long (0.3); apical compartment moderately large, approx. 3.0 times wider (0.3) than medially long (0.1); apical transverse carina (0.338), smaller than the subapical carina (0.372); angled formed by caudal margin, well triangular, laterally concave. Frons ( Fig. 63B ): 1.5 times longer (1.1) than wide (0.7); approx. 2.3 times wider medially than apically (0.3); in frontal view, anterior region of the frons trapezoidal, slightly elevated medially. Frontoclypeal suture, weakly bent upwards medially, straight laterally. Postclypeus ( Fig. 63B ): median carina weakly developed. Anteclypeus ( Fig. 63B ): median carina moderately developed sometimes weakly developed. Rostrum in ventral view surpassing slightly the base of the abdomen.

Thorax. Pronotum ( Figs. 63A, C ): submedian carinae developed, slightly irregular and evanescent behind the eyes; hind margin obtusely angled. Mesonotum ( Fig. 63A ): median carina weakly developed, evanescent or absent distally; lateral carinae well developed. Tegmina (Forewings) ( Fig. 63D ): length 6.6 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, inconspicuous spot in the post nodal region between RP1 and MP4, transversal spot weakly developed 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 MP fork; simple tubercles in all veins, slightly more visible on the A1/A2 fork; petiole in RP2.2+RP2.3 moderately developed; 12 apical cells; 7 subapical cells. Rostrum in ventral view surpassing slightly the base of the abdomen.

Posterior legs. Hind tibia ( Fig. 63E ): approximately 2.2 mm; with 3 spines laterally, first at the base of the tarsomere tiny. 1 st tarsomere ( Fig. 63F ): 7 apical teeth, two external lateral larger and two in the middle slightly smaller. 2 nd tarsomere ( Fig. 63F ): 8 apical teeth, the two external ones bigger (one larger) and the middle ones gradually smaller; 3 large platellae, one separated by apical teeth without platellae.

Male terminalia. Pygofer ( Figs. 64A–C, G ): bilaterally symmetric, in lateral view, dorsocaudal margin without process; caudal margin, straight; in ventral view, ventromedian process triangular, wider than tall. Anal tube ( Figs. 64A–C, G ; 65A–C ): tubular, distally developed, bent in 90°approx; in dorsal view, lateral margins slightly asymmetric, weakly narrow near base and broad distally; in lateral view, wider near the base; distal region moderately large and asymmetric; in ventral view distal margin weakly concave and slightly narrow medially; epiproct and paraproct short. Genital styles ( Figs. 64A–B, G ; 65D–F ): in lateral view, not much wider in the apical region than narrow near the base; ventral margin straight, slightly concave above the bent medially; dorsocaudal margin convex apically; dorsal margin with a moderately triangular region occurring above the bent medially. Aedeagus ( Figs. 64D–F ; 65G–I ): asymmetric tubular, with five spines, two movable (a, d) and one bifid (d). Shaft of the aedeagus with three spines; in right lateral view, 1 st spine longer and curved (a), occurs on the right apical region of the shaft; 2 nd spine smaller (b), slightly curved towards the base, occurs near the center of the shaft; in left lateral view, 3 rd spine small (c), occurs in the apical region of the aedeagal shaft towards the base. Flagellum with two spines, 4 th spine bifid and longer (d), occurs near of the base of the flagellum towards to ventral region; 5 th spine short (e), occurs on the apical region of the flagellum.

Female terminalia. Anal tube ( Figs. 66A, 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. 66A–B ). Ovipositor ( Figs. 66 A-B): in lateral view, sabre-shaped, curved upwards dorsally, strongly surpassing the anal tube.

Etymology. The specific epithet lundi honors the late Danish researcher Peter Wilhelm Lund. P. Lund had a great influence on the understanding of the Brazilian Pleistocene period from an infinity of fossils discovered in Brazilian caves, being considered the precursor of the Speleology and Paleontology sciences in Brazil.

Diagnosis. Pintalia lundi sp. nov. can be distinguished from other species of Pintalia mainly by the occurrence of a bifid spine at the base of the flagellum, facing the ventral region transversally and by the other four spines of the aedeagus.

Distribution. BRA, MG; Lagoa Santa and Itacarambi municipality, Helictites Cave (Type Locality).
