Measurements. Total length: 15.8–18.1; head length: 1.5–1.7; head width: 3.0–3.4; pronotal length: 2.8–3.5; pronotal width: 9.8–10.7; scutellum length: 7.4–8.3; scutellum width: 5.5–6.0; abdominal width: 8.6–9.9; length of antennal segments. I: 0.9–1.0; II: 1.7–2.5; III: 1.4–2.2; IV: 4.1–4.5; V: 4.3–4.9.

Diagnosis. Anterolateral margin of pronotum with solid black stripe along all or part of its extension; when stripe incomplete, remaining part smoky black and narrow. Anterolateral margin punctured dorsally. Cicatrices of pronotum with black punctures delimiting anterior sulci ( Fig. 19I View FIGURE 19 ). Scutellum with anterior margin yellow ( Fig. 19I View FIGURE 19 ). Body ventrally with dark brown stripes ( Fig. 19J View FIGURE 19 ). Male genitalia ( Fig. 11A–D View FIGURE 11 ). Pygophore dorsal rim excavated with a small triangular median projection ( Fig. 11A View FIGURE 11 ). Superior process of genital cup small and curved ventrally, ventral margin with digitiform expansion close to distal apex; adjacent to dorsal rim; visible in dorsal view ( Fig. 11A–C View FIGURE 11 ). Paramere golf club like, elongated, strongly bent laterally; anterior lobe rounded and short; posterior lobe tapering, curved dorsally, and concave ( Fig. 11B–C View FIGURE 11 ); stalk with high carina on inner face ending at apex of posterior lobe ( Fig. 11B–C View FIGURE 11 ). Proctiger with dorsolateral dense tufts of setae separated by narrow glabrous carina; posterior face pentagonal ( Fig. 11B–C View FIGURE 11 ). Ventral rim median excavation widely open and shallow; expansions little developed, rounded, strongly setose, just surpassing or level with posterolateral angles in ventral view ( Fig. 11D View FIGURE 11 ). Female genitalia ( Fig. 11E View FIGURE 11 ). Valvifers 8 subtrapezoidal with posterior margin almost straight; inner angle reaching half of valvifers 9; inner margins divergent in distal half and dark. Valvulae 9 exposed. Valvifers 9 strongly setose.

Comments. This species is related to H. trabeculus and H. similis by the paramere golf club like; posterior face of proctiger pentagonal; dorsal rim medially with a small convex expansion, and expansions of ventral rim with setae long and dense on apex ( Figs. 11A–D View FIGURE 11 , 14A–D View FIGURE 14 ; Nunes et al. 2020, Fig. 8A–C View FIGURE 8 ). However, in H. pentagonalis the posterior process of the paramere is curved dorsolaterally (straight in H. similis and H. trabeculus ). The superior process of genital cup is curved with a distal digitiform process on ventral margin (straight in H. trabeculus and curved but without ventral process in H. similis ). The valvifers 8 of these species are very similar, especially the mesial distal excavation V-shaped, but the outer angles of distal margin are more angulated in H. pentagonalis than in the other species.

Etymology. Name refers to the pentagonal form of the posterior face of the proctiger.
