Measurements. Total length: 14.8–16.8; head length: 1.5–1.9; head width: 3.0–3.3; pronotal length: 2.6–3.3; pronotal width: 9.2–10.2; scutellum length: 7.2–8.0; scutellum width: 5.1–5.8; abdominal width: 8.2–9.4; length of antennal segments. I: 1.0–1.1; II: 1.2–2.1; III: 1.1–1.5; IV: 3.1–4.8; V: 6.3.

Diagnosis. Anterolateral margin of pronotum with solid black stripe along all of its extension. Anterolateral margin punctured dorsally. Cicatrices of pronotum with brown to concolorous punctures delimiting anterior sulci ( Fig. 18I ). Scutellum with anterior margin greenish yellow ( Fig. 18I ). Body ventrally with dark brown stripes ( Fig. 18J ). Male genitalia ( Fig. 5A–D ). Pygophore with dorsal rim shallowly excavated, slightly convex in the middle ( Fig. 5A ). Superior process of genital cup laminar, oblique, short, tapering to the base, and adjacent to dorsal rim; visible in dorsal view ( Fig. 5A–C ). Paramere golf club like, elongated, laterally bent; inner margin with carina ending close to the apex of the posterior lobe; posterior lobe somewhat developed and rounded distally; anterior lobe developed and rounded; outer margin black and thick ( Fig. 5B–C ). Proctiger with tufts of dense and long setae along lateral margins separated dorsally by narrow bridge; posterior face pentagonal, slightly swollen laterally ( Fig. 5B–D ). Ventral rim median excavation widely open with expansions acuminated, large, surpassing level of posterolateral angles in ventral view; expansions with a tuft of setae; bottom of median excavation with a small central concavity ( Fig. 5D ). Female genitalia ( Fig. 5E ). Valvifers 8 subrectangular, posterior margin almost straight; margins black; inner angles reaching basal third of valvifers 9; inner margins divergent from the middle of the plate. Valvulae 9 exposed.

Comments. See comments of H. clavatum , additionally H. cristatus has the posterior lobe of the paramere rounded distally ( Fig. 5B ) and H. clavatum more acuminated ( Fig. 3B ).

Etymology. Name refers to the keel-like superior process of the genital cup (crista: crest)

Distribution ( Fig. 21A ). BRAZIL: Pará, Mato Grosso, Rondônia.
