Diagnosis. The species is similar to H. albipes and H. sphacelatus in the appearance and in the structure of the genitalia, but clearly differs from them in the deep median emargination of the pygofer, paramere bearing a large tooth, hypophysis symmetrically widened in the apical part, and coarser sculpture of the uneven area of the inner surface of the paramere ( Fig. 52 ).

Description. Length of body 8.5–10 mm. Similar to H. sphacelatus , with external structures, coloration, and morphometrical characters overlapping those of the latter.

Head. Jugae not covering clypeus, as long as latter.

Pronotum with sharp lateral edging wider in anterior part. This edging never taking form of callose costa. Punctation black. Proboscis always reaching posterior margin of metathorax.

Male genitalia. Pygofer with deep pointed emargination in apical part ( Fig. 65 ). Paramere with large tooth, hypophysis symmetrically widened at apex, and with well-developed uneven area on inner surface, covered with large scales ( Fig. 52 ).

Distribution. The eastern Pyrenees in France and Spain (Aragon and Northern Catalonia). The species was collected on Verbascum .
