Scybalocanthon kelleri Pereira & Martínez, 1956: 114  , 116 (original description and identification key); Vulcano & Pereira 1964: 638 (catalog); Vulcano & Pereira 1967: 554 (distribution, identification key); Halffter & Martínez 1977: 67 (species list).

Canthon kelleri: Krajcik 2006: 28  (catalog); Krajcik 2012: 63 (catalog).

Diagnosis. Specimens of S. kelleri  ( Fig. 1LView FIGURE 1) are similar to some specimens of S. sexspilotus  ( Fig. 2CView FIGURE 2) in having the pronotum bicolored, with a transverse black spot; aedeagus with parameres elongate, subrectangular, not excavated ventrally ( Figs. 4L, UView FIGURE 4); and endophallus lacking bristles or microbristles close to the FLP sclerite ( Figs. 5K, UView FIGURE 5). However, they can be distinguished by head, pygidium and femora uniformly colored.

Description. Body. Oval, lateral edges rounded. Surface completely microgranulate, with small and dense punctures randomly distributed. Color. Head and elytra opaque, pronotum with metallic sheen. Most of pronotum and elytra, lateral portion of hypomera, lateral portion of abdominal ventrites, and pygidium yellow or dark brown. Other parts black. Length. 7.7–9.0 mm. Thorax. Pronotum with transverse black spot in a butterfly or bat shape. Anterior angles of pronotum acute (approximately 80°). Lateral margin regularly curved outward, not forming an angle at the middle portion. Elytra. Striae thin and shiny, weakly impressed, punctures almost inconspicuous. Eighth stria with a thin carina at the anterior portion. Aedeagus. Parameres slightly asymmetrical, with subrectangular shape, truncate apically ( Fig. 4LView FIGURE 4). Dorsal margin of parameres slightly curved inward from the basal to medial portions and slightly curved outward at the apical portion. Ventral margin of parameres substraight. SRP circular, with curved handle-shaped extension ( Fig. 5KView FIGURE 5). FLP I-shaped ( Fig. 5KView FIGURE 5). A+SA with two superposed and elongate sclerites ( Fig. 5KView FIGURE 5). AS I-shaped ( Fig. 5KView FIGURE 5).

Type material. Scybalocanthon kelleri Pereira & Martínez  , holotype ♂ ( MZSP): “Sosomoco / Ost Columb.” //  “ HOLOTYPUS ” / / “ Scybalocanthon  / kelleri  sp. n. ♂ / F. S. Pereira ” // “ Canthon  / nigriceps  / Har. / P. Pereira det. 951” // “10196”  .

Burger— 1♂ ( CEMT)GoogleMaps  . ECUADOR: NAPO, Tena , 400–500 m (0°59’21’’S, 77°48’55’’W), 15–21.ii.1986, F. Génier, feces trap— 1♂ 1♀ ( CMNC)GoogleMaps  .

Distribution. Known from Colombia and Ecuador ( Fig. 6AView FIGURE 6). Endemism areas: Brazilian sub-region: Pacific dominion: Sabana and Magdalena provinces; Boreal Brazilian dominion: Napo province (see Morrone 2014; fig. 12).

Remarks. “Sosomoco” is apparently an incorrect citation for quebrada Susumuco in the eastern portion of the Meta department in Colombia ( Maldonado-Ocampo et al. 2005; Salazar 2008).
