Diagnosis: hemibrachypterous; anterior frontal edge with small middle indentation; area mediofrontal heavily punctuated on the anterior half, divided by a longitudinal sulcus which reaches to the base of the central tubercle, the last one with apex not free. mediofrontal+ laterofrontal tubercles same size than internal tubercles.

Description.

Habitus ( Figs. 2 c-d): total length 32.8–34.2 mm, hemibrachypterous, body convex shiny black.

Head ( Figs. 2 a-b and 3a): labrum with anterior border almost straight, with a small medial projection, evenly covered by setae. Clypeus hidden under the frons, anterior angles developed under the mediofrontal + laterofrontal tubercles and slightly smaller than these. Frons wide, anterior frontal edge with small middle indentation, without secondary mediofrontal tubercles. Mediofrontal + laterofrontal tubercles projected forward, midsize, same size than internal tubercles. Internal tubercles big, projected upwards, not joined to mediofrontal + laterofrontal tubercles by ridge, placed at mid distance between the mediofrontal tubercles and the central tubercle apex. Posterofrontal ridges “V” shaped. Area between the frontal ridges heavily punctuated on the anterior half, divided by a sulcus that extends from the anterior border to the base of the central tubercle. Cephalic mamelon (sensu Jiménez-Ferbans & Reyes-Castillo 2014) present and divided. Mesofrontal structure of the “marginatus” type ( Reyes-Castillo 1970), with central tubercle wide at the base, without a sulcus in the posterior part, apex not free. Lateroposterior tubercles slightly marked and rounded. Lateropostfrontal areas glabrous, shiny, and punctate posteriorly. Eyes reduced, with canthus covering ½ of the eye in lateral view. Canthus glabrous. Postorbital pits weak. 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, heavily punctate and pubescent. Mentum with big lateral fossae, shallow and pubescent. Antennal club trilamellate. Dorsal tooth straight on dorsal view and slightly sinuous on lateral view. Dorsal mandibular pubescence covering the base of the mobile tooth, not reaching the base of the internal tooth. Internal tooth of the left mandible bidentate, simple on the right mandible. Mandibular fossae short, not reaching the base of the mobile tooth. Maxilla with lacinia bidentate at the apex. Ligula tridentate, with middle tooth longer than lateral teeth. Middle palpomere of the labial palp 1.3 times wider and with almost the same length as the distal palpomere.

Thorax ( Figs. 2 a-b): Pronotum rounded, wider than elytra, with punctuations restricted to the lateral fossae and marginal groove. Marginal groove wide, occupying ¾ of the anterior margin of the pronotum. Longitudinal sulcus well marked. Lateral fossae marked. Prepimerum opaque and heavily pubescent. Prosternellum rhomboidal and opaque. Mesosternum without mesosternal scars, indicated only by an opaque area, impunctate and glabrous. Posterior corner of the mesepisternum and mesepimere glabrous. Anterolateral part of metasternum and lateral fossa pubescent. Metasternal disc without punctures, delimited by numerous punctures medially and posteriorly. Posterior metasternal lateral fossa of the same width as epipleura.

Elytra ( Fig. 2c ): Shiny, anterior border straight and glabrous. Humeri and Epipleura glabrous. Striae with rounded punctures, more marked on lateral striae.

Abdomen ( Fig. 2d ): Last sternite with marginal groove complete.

Legs ( Figs. 2 c-d): profemur with ventral anterior marginal sulcus thin and complete, reaching the apical pubescence. Protibiae with dorsal sulcus complete. Mesotibiae with small spines on the outer margin. Metatibiae unarmed.

Aedeagus ( Figs. 3 b-c): Basal piece (ventral view) fully fused with parameres and with deep “v”-shape cleft. Median lobe globose, little sclerotized on ventral surface, length is 1.1 times the length of the basal piece and parameres, measured at the median ventral line. Lateral projections of the parameres short and apex truncated on lateral view.

Variation: punctures on the area between the frontal ridges are surrounding the cephalic mamelón in the holotype, whereas they are only in the anterior part in the paratype. On the other hand, the middle indentation in the frons border is more marked in the paratypes than in the holotype.
