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)
