Cyrtomenus (Syllobus) marginalis ; Froeschner, 1960: 521.

Material examined: Photos from the holotype provided by Harald Bruckner.

Diagnosis: Dorsal surface of the mandibular plates, punctate; mandibular plates of the same length than clypeus; second antennal segment as long as third; 25–30 lateral submarginal setigerous punctures of the pronotum; Transverse impression marked by a band of punctures; Posterior lobe of the pronotum and disc of the scutellum densely punctate; 21–25 setigerous punctures on the costa.

Redescription. Total length: 7.07 mm

Head flattened dorsally, anterior outline broadly semicircular, surface shining, mandibular plates with prominent radiating rugae and numerous close-set, intermixed moderate and fine punctures; clypeus shorter than mandibular plates ( Fig. 18B View FIGURE 18 ); labium broken, only first segment present.

Thorax: Pronotum surface shining almost totally covered by crowded moderate and minute punctures, disc impunctate; lateral margin with submarginal row of 25 setigerous punctures; transverse impression weak. Scutellum punctured uniformly. Hemelytron surface shining, clavus with two incomplete rows of punctures; mesocorium and exocorium with several moderate punctures sparser than in scutellum; costa with 21 to 23 setigerous punctures ( Fig. 18A View FIGURE 18 ). Mesopleural evaporatorium with pseudoperitreme. Metatibia compressed ( Fig. 18D View FIGURE 18 ).

Abdomen: Sternites III to VI with irregular, postmedian row of setigerous punctures across segments ( Fig. 18D View FIGURE 18 ).

Type data: The holotype specimen is a female deposited in NHM Wien, labeled: “ Brasil ”, coll. Signoret.
