(Figs. 5, 6, 9, 10, 13, 14, 17–20, 24–26, 29, 30)
Type locality: Tolé, Panama.
Alkindus atratus Distant, 1889: 309; Lethierry & Severin 1893: 14 (catalogue); McAtee & Malloch 1933: 348–349 (redescription); Becker & Grazia-Vieira 1971: 9 (distribution records); Maes 1994: 21 (catalogue).
Diagnosis. Head (Fig. 5). Ocelli almost equidistant from middle of vertex and from eyes; head posterior to ocelli about 2.2 times the diameter of ocelli.
Pronotum. Broad lateral punctate area. Callus slightly rastrate.
Hemelytra (Fig. 6). Width of subcostal area uniform at first half, narrower posteriorly. Branches of exocorial vein divergent in middle part of their course.
Abdominal venter (Figs. 9, 13). Sternite VII on average 0.6 and 1.2 times the length of segments III–VI in female and male, respectively; anterior margin of sternite VII broadly rounded in female and narrowly rounded to sub angulate in male, posterior margin rounded in both sexes. Lateral bristles present on all visible abdominal segments (including laterotergites 8 and 9 in female), these longer and thicker than the trichobothria, located laterally and in line with anterior trichobothria.
Male genitalia (Figs. 13, 14, 30). Ventral exposure of pygophore long, about 0.4 times the length of urosternite VII, more densely punctate anteriorly and laterally. Ventral rim convex at median third, slightly bilobate; with 1 + 1 acute posterior projections at lateral thirds.
Measurements (n=9). Total length 4.7 (4.5–5.0) ± 0.2; head length 0.9 (0.9–1.1) ± 0.1, width 2.0 (1.9–2.1) ± 0.1; eye width 0.2 (0.2–0.3) ± 0.0; interocular distance 1.5 (1.4–1.6) ± 0.1; anteocular length 0.4 (0.4–0.5) ± 0.0; length of antennal segments: I—0.4 (0.4–0.5) ± 0.0; II—0.2 (0.1–0.2) ± 0.0; III—0.3 ± 0.0; IV—0.4 (0.3–0.4) ± 0.0; V—0.5 (0.4–0.5) ± 0.0; pronotal length 1.4 (1.3–1.5) ± 0.1, width 3.1 (3.0–3.4) ± 0.1; scutellar length 2.9 (2.6– 3.2) ± 0.2, width 2.7 (2.5–2.8) ± 0.1; abdominal width 3.0 (2.9–3.3) ± 0.1; corium length 2.1 (2.0–2.3) ± 0.1; rostrum length 1.7 (1.7–1.8) ± 0.0.
Female genitalia (Figs. 9, 10, 29). Posterior margins of gonocoxites 8 slightly concave; anterior half of mesial margins ventrally projected; mesial margins about 1.3 times the length of abdominal sternite VII at midline and 1.3 times the length of posterior margins of gonocoxites 8.
Measurements (n=7). Total length 5.1 (4.7–5.6) ± 0.3; head length 1.0 (1.0–1.1) ± 0.1, width 2.2 (2.1–2.3) ± 0.1; eye width 0.3 ± 0.0; interocular distance 1.6 (1.6–1.8) ± 0.1; anteocular length 0.4 (0.4–0.5) ± 0.0; length of antennal segments: I - 0.5 (0.4–0.5) ± 0.1; II - 0.2 ± 0.0; III - 0.3 (0.3–0.4) ± 0.0; IV - 0.4 ± 0.0; V - 0.5 (0.5–0.6) ± 0.0; pronotal length 1.5 (1.4–1.8) ± 0.1, width 3.5 (3.3–3.7) ± 0.2; scutellar length 3.1 (2.9–3.3) ± 0.2, width 3.0 (2.8–3.3) ± 0.2; abdominal width 3.4 (3.2–3.6) ± 0.2; corium length 2.3 (2.1–2.4) ± 0.1; rostrum length 1.9 (1.8– 2.1) ± 0.1.
