Diagnosis.

Brachypterous. Frons wide, anterior frontal edge straight, with middle indentation and secondary mediofrontal tubercles small (rudimentary). Central tubercle wide at the base, with a sulcus in the posterior part, apex free, reaching the anterior frons border. Medial basal mentum with punctures and setae on the posterior border. Prosternellum rhomboidal and opaque in the area between procoxae, with a deep longitudinal groove. Anterolateral part of metasternum with scarce pubescence, lateral fossa glabrous. Metasternal disc without punctures, delimited by numerous punctures medially and posteriorly. Humeri with scarce pubescence basally, epipleura glabrous.

Description.

Habitus (Fig. 9B-D ): total length 36.7-37.8 mm, hemibrachypterous, body convex shiny black.

Head (Figs 9A, D , 10A ): labrum with anterior border concave, covered by setae less dense in the middle region. Clypeus hidden under the frons, anterior angles under the mediofrontal + laterofrontal tubercles and smaller than these. Frons wide, anterior frontal edge straight, with middle indentation and secondary mediofrontal tubercles rudimentary. Mediofrontal + laterofrontal tubercles projected forward, larger than internal tubercles. Internal tubercles small, rudimentary, joined to mediofrontal + laterofrontal tubercles by an inconspicuous ridge, placed at mid distance between the mediofrontal tubercles and the central tubercle base. Posterofrontal ridges V-shaped, inconspicuous. Area between the frontal ridges 3 punctures with a median sulcus and without cephalic mamelon (sensu Jiménez-Ferbans and Reyes-Castillo 2014). Mesofrontal structure of the " Popilius marginatus " type ( Reyes-Castillo 1970), with central tubercle wide at the base, with a sulcus in the posterior part, apex free, reaching or surpassing anterior frons border. Lateroposterior tubercles large, parallel to central tubercle. Lateropostfrontal areas glabrous, shiny, and impunctate. Eyes reduced, not extending past ocular canthi (dorsal view) and with canthus covering almost 1/2 of the eye in lateral view. Canthus glabrous. Postorbital pits shallow. Postfrontal groove semicircular and complete. Hypostomal process slightly separated from mentum, glabrous and reaching the superior part of the middle zone of the mentum. Medial basal mentum protruding ventrally, with punctures and setae on posterior border. Mentum with rounded lateral fossae, shallow and pubescent laterally. Antennal club tri-lamellate. Dorsal tooth straight on dorsal view and slightly sinuous on lateral view. Internal tooth bidentate on left and right mandible. Mandibular fossa short, not reaching the base of the mobile tooth. Maxilla with lacinia bidentate at the apex. Ligula tridentate, with middle tooth longer than the lateral teeth. Middle palpomere of the labial palp 1.3 × wider and with almost the same length as the distal palpomere.

Thorax (Fig. 10B-D ): Pronotum rounded, slightly wider than the elytra, with 3-10 punctures in or around lateral fossae. Marginal groove wide, occupying ¾ of the anterior margin of the pronotum. Longitudinal sulcus conspicuous. Lateral fossae distinct. Prepimerum shiny and pubescent. Prosternellum rhomboidal and opaque in the area between procoxae, with a deep longitudinal groove. Mesosternum with erased mesosternal scars, indicated by an opaque area, impunctate and glabrous. Posterior corner of the mesepisternum and mesepimere glabrous and opaque. Anterolateral part of metasternum with scarce pubescence, lateral fossa glabrous. Metasternal disc without punctures, delimited by numerous punctures medially and posteriorly. Posterior metasternal lateral fossa narrower than epipleura.

Elytra (Fig. 9B, D ): Shiny, anterior border straight and glabrous. Humeri with scarce pubescence basally, epipleura glabrous. Striae with rounded punctures, more distinctive on lateral striae.

Abdomen (Fig. 9C ): Last sternite with marginal groove incomplete.

Legs (Fig. 9C ): profemur with ventral anterior marginal sulcus thin and complete, reaching the apical pubescence. Protibiae with dorsal sulcus complete. Mesotibiae with a small spine on the outer margin. Metatibiae unarmed.

Aedeagus (Fig. 9C, D ): Basal piece (ventral view) fully fused with parameres and with deep V-shape cleft. Median lobe globose, little sclerotized on the ventral surface, length is 1.1 × the length of the basal piece and parameres, measured at the median ventral line. Lateral projections of the parameres short and apex rounded on lateral view.

Variation: In some paratypes, the area between the frontal ridges has 0-4 punctures, and the metasternal disc with 0-10 punctures.

Etymology.

Named after Mr. Víctor Flórez Carrillo, for his dedication to entomological exploration in the Serranía del Perijá.
