Material examined (n=3). Holotype ♂: BRAZIL. Amazonas. Benjamin Constant, Rio Javary alto Amazonas , 6.IV.1942, B. Pohl leg. ( MZUSP) . Paratypes: Same data holotype : ♂ II.1952, Coll. Dirigins S. Paulo – Brazil 225, Col. MRCN 003684 ( MZUSP) ; ♀ I.1962, Dirigins leg. ( MZUSP) .

Measurements. Total length: 15.5–15.8; head length: 1.5–1.8; head width: 3.0–3.2; pronotal width: 8.9–9.8; abdominal width: 7.9–8.7; length of antennal segments. I: 0.9–0.9; II: 1.7–1.8; III: 1.2–1.4; IV: 4.0–4.5; V: 3.5–0.0; interocular distance: 1.4–1.5; scutellum length: 6.4–7.6; scutellum width: 5.0–5.6; pronotal length: 3.0–3.0.

Diagnosis. Anterolateral margin of pronotum with complete solid black stripe. Anterolateral margin with black punctures dorsally. Cicatrices with black punctures delimiting anterior sulci ( Fig. 19K View FIGURE 19 ). Scutellum with anterior margin yellow ( Fig. 19K View FIGURE 19 ). Body ventrally with dark brown stripes ( Fig. 19L View FIGURE 19 ). Male genitalia ( Fig. 12A–D View FIGURE 12 ). Pygophore dorsal rim shallowly excavated ( Fig. 12A View FIGURE 12 ). Superior process of genital cup half-moon shaped, inner angle acute, ventral margin with developed median triangular projection; touching dorsal rim; visible in dorsal view ( Fig. 12A–C View FIGURE 12 ). Paramere club-like, elongated, laterally bent, margin black; anterior lobe slightly developed and rounded; posterior lobe narrow and truncated; inner face of the stalk with tiny carina ending before bent part ( Fig. 12B–C View FIGURE 12 ). Proctiger with dorsolateral tufts of long setae separated by dorsal narrow ridge; posterior face longer than wide, basal half rugulose with a central fold, ventral margin biconvex ( Fig. 12A–D View FIGURE 12 ). Ventral rim with median excavation in “U”; expansions setose, rounded, wide, surpassing level of posterolateral angles in ventral view ( Fig. 12D View FIGURE 12 ). Female genitalia ( Fig. 12E View FIGURE 12 ). Valvifers 8 with posterior margin slightly sinuous, inner angles acuminated to rounded, reaching base of valvifers 9; an almost distal fold hides posterior margin in ventral view; inner margins dark, divergent on distal 2/3, median excavation cup like. Valvulae 9 exposed.

Comments. This species shows the lateral margins of the posterior face remarkably projected ventrally. Only H. omegoides has the proctiger projected ventrally, but in a completely different way; also other parts of the pygophore separate them ( Figs. 12A–D View FIGURE 12 , 10A–D View FIGURE 10 ). Female has the genital plates similar to H. flexuosus and several species with elliptical median excavation of the valvifers 8, but the fold adjacent to posterior margin can separate them.

Etymology. Name refers to the rugulose basal half of the posterior surface of proctiger.

Distribution ( Fig. 21A View FIGURE 21 ). BRAZIL: Amazonas.
