Diagnosis: This species presents scale-like projections on the anterior part of the hemelytra border, and also differs from H. colombiensis by the anterior branch of the scent gland peritreme, more curved and shorter, and by the entirely enlarged edges on the posterior branch, and by its subcostal area, only less than twice wider than the costal area in its widest part.

Description: Body: Head, pronotum, hemelytra light brown ( Fig. 30A View Figure 30 ); antennae, rostrum legs and abdomen even lighter, yellowish. Head: Pubescent; eyes fully developed, length less than half of length of the head; antenniferous process small, less than one-eighth of pedicel length; pedicel less than three times longer than scape, basi- and distiflagellomere missing; bucculae roundish, narrower posteriorly, border pubescent, few coarse punctations near junction with head, a second-row compound by three smaller punctates present, posterior border straight ( Fig. 30E View Figure 30 ); rostrum only reaching first abdominal segment ( Fig. 30B, C View Figure 30 ). Thorax: Hairs mostly anteriorly, finely punctate, except for middle of posterior lobe; paranota explanate, narrowing posteriorly, border sinuous, lightly pubescent ( Fig. 30F View Figure 30 ); scutellum large, less than one-third the maximum width of pronotum ( Fig. 30D View Figure 30 ); sternal laminae narrow, punctate. Hemelytra: Margins with scale-like projections anteriorly; clavus coarsely punctate; discoidal, subcostal areas coarsely punctate anteriorly, then fading to become only finely punctate; discoidal area about two and a half times subcostal area at its widest; subcostal area wider at middle, extending to the apex of membrane; costal area broadening posteriorly, widest at middle; membrane without inner row of punctuation. Scent gland: Anterior branch strongly inclined forward, tip curved horizontally and distant from hemelytra border, short and not swollen, sulcus barely present, fading distally; posterior branch tip curved, sulcus prominent through its entire length ( Figs 16K View Figure 16 – 30C View Figure 30 ).
