Description. Body. Head dark green with weak sheen or opaque, pronotum in copper tone, with black or greenish spots, elytra reddish-brown, with an opaque sheen (Figs 72, 99). Ventral surface black with a greenish sheen. Length 11 to 13 mm. Head. Dorsal surface with dense foveiform punctures, not confluent, separated at center of dorsal interocular surface by approximately twice their diameter. Punctures of variable size; largest around the eyes, smallest closer to antero-lateral portion, near the clypeus. Anterior margin of each puncture not defined (as in Fig. 60). Margin between clypeal teeth and genae curved outward approximately at halfway of its length. Thorax. Surface of pronotum with small punctures, apparently simple and uniformly distributed. Punctures located on anterior angles with a typical foveiform shape. Pronotum with a narrow greenish band extending the entire edge. Posterior edge with band "I"-shaped (Fig. 99); this band can extend up to the disc of pronotum. Margin of pronotum (close to lateral angles) straight and emarginated, without depression. Elytra. Lateral margins evenly curved outward, with narrow dark spot, more visible on anterior portion. Striae faintly visible at a small magnification (Fig. 72). Interstrial surface with small, dispersed foveiform punctures amid small bright ocellate punctures, randomly distributed. First interstria brighter than rest of elytra. Basal carina of seventh interstria short, length about twice the width of the seventh interestria (Fig. 72). Length of apical carina of seventh interstria approximately 2.5 times that of apical carina of sixth interstria. Abdomen. Punctures large and conspicuous, concentrated anterolaterally on each sternite, reduced to a narrow belt along midline of abdomen (as in Fig. 73). Pygidium with dense foveiform punctures, transverse, elliptical and almost confluent at base. Apex of pygidium acuminate (as in Fig. 73). Legs. Protibia not abruptly widened (Fig. 99). Middle protibial tooth equidistant between apical and basal teeth. Protibial spur acuminate at apex. Apical third of metatibia only slightly curved inward (as in Fig. 68), with five clearly visible longitudinal carinae. Inner margin of metatibia with a longitudinal row of small tubercles. Anterior edge of profemur completely emarginate, with abundant setae in two-thirds of its length. Foveiform punctures of profemur with transverse elliptical shape. Metatarsus approximately two-thirds as long as metatibia. Secondary sexual characters. Male abdomen more longitudinally flattened than that of female. Males may possess a small tubercle medially between first and second ventrites. Apical margin of pygidium longer in male. Protibial spur more acuminate in female.

Autuori (1 ♀ DZUP).
Sampling methods. baited pitfall trap with injured diplopods [6 specimens].
Habitat. Bolivia and Brazil (Goiás and Mato Grosso) (Fig. 90), from available data this species inhabits Cerrado and Chaco. Six individuals were collected in "Chiquitano Cerrado".
Diagnosis and remarks (within the cupreicolle complex): basal carina of seventh interstria short, length about twice the width of the seventh interestria (Fig. 72); elytra reddish-brown or dark brown, with an opaque sheen (Fig. 99). The following aedeagus characters are also diagnostic: parameres shorter than phallobase, slightly rounded at apex, in lateral view forming an angle of approximately 45° with phallobase (Fig. 5). Lamella copulatrix (LC): left lobe “J”-shaped (Fig. 33); right lobe baton-shaped (Fig. 33). Fronto-lateral peripheral sclerite (FLP) as in Fig. 50. Center of genital segment with a well-sclerotized portion and "T"-shaped (Fig. 25).
The coloration of pronotum can vary between dark brown and copper. The color of elytra can also vary from reddish-brown to dark brown. Most specimens do not present a round spot on disc of pronotum. When this spot is present, elytra are never dark brown.
Based on examination of the types, we can find no significant difference between Hyboma cupreicolle Blanchard 1841 and Canthon cupricolle Lucas 1859, we therefore confirm that C. cupricolle Lucas is a junior synonym of Deltochilum cupreicolle (Blanchard 1841).
