Diagnosis. Flat body (Fig. 5); labium almost attaining the posterior margin of urosternite III (Fig. 4); metasternal carina widened and evanescent posteriorly; peritremal disc not attaining the lateral third of metapleura (Fig. 9); pygophore (Figs. 10–15) with lateral margins subparallel; ventral rim with a dense tuft of setae next to posterolateral angles; paramere dish-shaped process small and shallow; apical bifurcation of paramere converging (Figs. 18–20).
Description. Body dorsoventrally flattened (Fig. 5). Punctures black, minute on head, denser on scutellum and hemelytra than on pronotum (Fig. 3). Head 1.2 times wider than long; labium almost attaining the posterior margin of urosternite III (Fig. 4). Thorax. Pronotal anterior margin deeply concave, anterolateral angles in a minute spine (Fig. 7). Scutellar apex rounded. Metasternal carina widened and evanescent posteriorly. Peritremal disc not attaining the lateral third of metapleura (Fig. 9). Abdomen. Connexiva pale brown. Urosternites darker than the dorsal body surface; spiracles dark, not contrasting with the surrounding surface (Fig. 4).
Male. Measurements (n=2): Total length 14.05 ± 0.63 (13.6–14.15); width of abdomen 8.05 ± 0.35 (7.80– 8.30); head length 2.15 ± 0.07 (2.10–2.20); width 2.65 ± 0.07 (2.60–2.70); pronotum length 3.30 ± 0.00 (3.30); width 7.40 ± 0.28 (7.20–7.60); scutellum length 5.55 ± 0.49 (5.20–5.90); width 4.50 ± 0.14 (4.40–4.60); length of antennomeres: I 0.85 ± 0.07 (0.80–0.90), II 0.85 ± 0.07 (0.80–0.90), III 1.35 ± 0.07 (1.30–1.40), IV –; V–; length of labiomeres: I 1.25 ± 0.21 (1.10–1.40), Int 0.20 ± 0.00 (0.20), II 2.15 ± 0.07 (2.10–2.20), III 1.65 ± 0.07 (1.60–1.70), IV 1.50 ± 0.00 (1.50).
Genitalia (Figs. 10–20). Pygophore. Lateral margins subparallel (Fig. 10); dorsal wall length on midline subequal to segment X length (Fig. 10); dorsal rim forming an open “v” over segment X (Figs. 10–12); posterolateral angles narrowly excavated, forming a pit (Figs. 10–12); ventral rim with a dense tuft of pale setae next to posterolateral angles, posterior to a small subtriangular projection (Figs. 12, 15); middle half of ventral rim “u”-shaped (Fig. 15). Segment X with lateral long, contrasting pale setae (Figs. 10–12). Parameres laterally compressed, dish-shaped process small and shallow; apical bifurcation of paramere converging, external branch longer than the internal (Figs. 18–20). Phallus moderately sclerotized; proximal thecal width less than three times the maximum thecal width in lateral view (Fig. 16, th); dorsal process of endosoma shorter than the rigid part of the ventral process of endosoma (Fig. 16, dpe, vpe); apical lobes of the dorsal process of endosoma small (Fig. 17), about the same size of the lobes of the ventral process of theca; ventral process of endosoma several times longer than theca, rigid at base and flexible and spiraled along its length (Fig. 16, vpe).
Female. Measurements (n=2): Total length 15.04 ± 0.70 (14.90–15.90); width of abdomen 8.20 ± 0.28 (8.00– 8.40); head length 2.20 ± 0.00 (2.20); width 2.85 ± 0.21 (2.70–3.00); pronotum length 3.60 ± 0.14 (3.50–3.70); width 7.80 ± 0.28 (7.60–8.00); scutellum length 5.75 ± 0.35 (5.50–6.00); width 4.30 ± 0.00 (4.30); length of antennomeres: I 0.95 ± 0.07 (0.90–1.00), II 0.80 ± 0.14 (0.70–0.90), III 1.30 ± 0.14 (1.20–1.40), IV 1.90 ± 0.00 (1.90); V–; length of labiomeres: I 1.35 ± 0.07 (1.30–1.40), Int 0.20 ± 0.00 (0.20), II 2.10 ± 0.00 (2.10), III 1.65 ± 0.07 (1.60–1.70), IV 1.50 ± 0.14 (1.40–1.60).
Genitalia (Figs. 21–24). Valvifers VIII wider than long, posterior margins straight, sutural margins juxtaposed (Fig. 21, vfVIII); laterotergites VIII as wide as long, posterior margin projected in spine, spiracles visible next to the posterior margin of valvifers VIII (Fig. 21, laVIII); laterotergites IX trapezoidal with acute apices, mesial margin convex (Fig. 21, laIX). Thickening of vaginal intima circular, more sclerotized on posterior margin (Fig. 24, tgvi); secondary thickenings of valvulae IX subtriangular, ring sclerites elliptical (Fig. 24, tgIX, rs); proximal portion of ductus receptaculi (Fig. 22, drp) spiraled and longer than vesicular area; distal portion of ductus receptaculi dilated towards the pars intermedialis (Figs. 22, 23, drd), three times longer than pars intermedialis and capsula seminalis taken together (Fig. 23, cs, pi); median duct of vesicular area cylindrical, as wide as the proximal portion of ductus receptaculi; pars intermedialis three times longer than capsula seminalis, this with three digitiform projections.
