Measurements. Total length: 14.8–16.5; head length: 1.8–2.1; head width: 3.0–3.3; pronotal length: 2.6–2.8; pronotal width: 9.2–9.9; scutellum length: 7.3–7.9; scutellum width: 5.0–5.7; abdominal width: 8.4–9.1; length of antennal segments. I: 0.9–1.0; II: 1.7–2.0; III: 1.1–1.5; IV: 4.2–4.8; V: missing.

Diagnosis. Anterolateral margin of pronotum with solid black stripe reaching all of its extension. Anterolateral margin punctured dorsally. Cicatrices of pronotum with brown to concolorous punctures delimiting anterior sulci (Fig. 20C). Body ventrally with brown stripes (Fig. 20D). Male (Fig. 14A–D). Pygophore dorsal rim slightly expanded and convex medially (Fig. 14A). Superior process of genital cup half-moon shaped; adjacent to dorsal rim; partially visible in dorsal view (Fig. 14A–C). Paramere elongated, golf club shaped, inner margin with conspicuous carina ending at rounded apex of posterior lobe (Fig. 14B–C). Proctiger with dorsolateral tufts of long setae separated by almost glabrous carina; posterior face pentagonal (Fig. 14A–D). Ventral rim median excavation widely open; expansions rounded, setose apically, surpassing level of posterolateral angles in ventral view (Fig. 14D). Female genitalia (Fig. 14E). Valvifers 8 posterior margin arched, inner angle covering more than half of valvifers 9; inner margin divergent in distal third. Valvulae 9 barely exposed.

Comments. See comments of H. pentagonalis .

Etymology. Name refers to the similarity between the dorsal rim of this species and H. cristatus sp. n. and H. pentagonalis sp. n .. These species show the dorsal margin of the pygophore slightly expanded medially.
