Head wider than long; maximum head width across the mandibular plates subequal to half the head width across the eyes; posterior margins of the eyes forming an angle of less than 45º with the longitudinal body axis; each mandibular plate wider than clypeus, with the outer margin convex and the inner margin concave anterior to clypeus, apex acute; antennomeres I not surpassing the mandibular plates, proportion of antennomeres: I ≅ II<III ≅ IV<V ( Fig. 31 View FIGURE 31 , A); labium attaining urosternite III ( Fig. 30 View FIGURE 30 , B), with an inconspicuous intercalary segment between labiomeres I an II ( Fig. 31 View FIGURE 31 , B); proportion of labiomeres: I<II>III>IV.

Thorax. Pronotum 2.5 times wider than long; anterior margin shallowly concave, lateral margins weakly sinuous ( Fig. 31 View FIGURE 31 , A). Lateral half of the corial posterior margin weakly concave, apical angle attaining the middle of connexival segment VI ( Fig. 30 View FIGURE 30 , A). Metasternum transversely arched.

Abdomen. Medial portion of urosternites unpunctured ( Fig. 30 View FIGURE 30 , B); trichobothria lateral to spiracles.

Male. Measurements (n=1): Total length 13.50; width of abdomen 6.00; head length 2.00; width 2.50; pronotum length 2.40; width 6.00; scutellum length 5.10; width 3.70; length of antennomeres: I 0.90, II 0.90, III 1.70, IV -, V -; labium missing.

Genitalia ( Fig. 32 View FIGURE 32 ). Pygophore. Lateral margins straight anterior to and convex at the posterolateral angles ( Fig. 32. A, E View FIGURE 32 ); dorsal wall length on midline as long as segment X; dorsal rim concave over segment X ( Fig. 32. A View FIGURE 32 ); posterolateral angles acutely rounded, dorsally excavated, and exceeding the segment X for about the latter’s length ( Fig. 32. A, B View FIGURE 32 ); ventral rim u-shaped, sinuous, with two dense tufts of setae close to the apex of posterolateral angles ( Fig. 32. E View FIGURE 32 ). Segment X with dense setae along the broad ogival posterior margin and an acute process posteriorly directed ( Fig. 32 View FIGURE 32 , A–C). Parameres laterally sinuous, dish-shaped process with a tuft of thin setae on the apical portion; head of parameres bifurcated, with external branch narrower and longer than internal ( Fig. 32 View FIGURE 32 , A, B).

Measurements (n=3): Total length 14.50 ± 0.34 (14.50–13.90); width of abdomen 6.40 ± 0.15 (6.50– 6.20); head length 1.70 ± 0.20 (1.80–1.40); width 2.60 ± 0.05 (2.70–2.60); pronotum length 2.50 ± 0.05 (2.50–2.40); width 6.10 ± 0.10 (6.20–6.00); scutellum length 5.40 ± 0.10 (5.50–5.30); width 3.80 ± 0.15 (4.00–3.70); length of antennomeres: I 0.80 ± 0.11 (1.00–0.80), II 0.80 ± 0.10 (0.90–0.70), III 1.50 ± 0.00 (1.50–1.50), IV 1.70 ± 0.05 (1.80–1.70), V (n=2) 1.85 ± 0.35 (2.10–1.60); length of labiomeres: I 0.90 ± 0.05 (1.00–0.90), Int. 0.20 ± 0.00 (0.20–0.20), II 1.50 ± 0.15 (1.60–1.30), III 1.40 ± 0.00 (1.40–1.40), IV 1.10 ± 0.05 (1.20–1.10).

Genitalia ( Fig. 33 View FIGURE 33 ). Valvifers VIII as long as wide, lateral angles slightly posteriorly projected relative to the sutural angles, posterior margins straight over the plates of segment IX ( Fig. 33 View FIGURE 33 , A, vfVIII); laterotergites VIII wider than long ( Fig. 33 View FIGURE 33 , A, laVIII); laterotergites IX with lateral margins straight, mesial margins convex, and rounded apices not surpassing the mediotergite VIII ( Fig. 33 View FIGURE 33 , A, laIX). Thickening of the vaginal intima subrectangular; ring sclerites subtriangular in ventral view, 1.5 times wider than the thickening of the vaginal intima ( Fig. 33 View FIGURE 33 , B); proximal portion of ductus receptaculi coiled and longer than vesicular area ( Fig. 33 View FIGURE 33 , B, drp); median duct of vesicular uniformly wide through its length; distal portion of ductus receptaculi dilated towards the pars intermedialis, 1.5 times longer than pars intermedialis and capsula seminalis taken together ( Fig. 33 View FIGURE 33 , B, drd); pars intermedialis twice longer than capsula seminalis, this with three digitiform projections ( Fig. 33 View FIGURE 33 , B, pi, cs).

Comments. Similar to Janeirona vianai and Janeirona stenosa Sampaio & Campos sp. nov.. Differs from J. vianai by the elongated body, labium attaining the urosternite III, labial intercalary segment, and the not twisted external branch of the head of parameres. Differs from J. stenosa Sampaio & Campos sp. nov. by the maximum head width across the mandibular plates subequal to half the head width across the eyes, antennomeres I not surpassing the mandibular plates, and inner margin of mandibular plates concave anterior to clypeus. Differs from all species in the genus by the yellowish legs.

Distribution: Brazil (Rio Grande do Sul).
