Medium-sized, dorsally ferruginous to red with relatively uniform black punctuations, venter dark red to black, punctation mostly concolorous with surrounding surfaces ( Figs 4–6 ).

Head ( Figs 19–21 ) dark yellow to red. Apex of mandibular plates rounded, subequal to or slightly surpassing clypeus, moderately elevated, clypeus and lateral margins of head darker than the remainder of head. Antennae dark red to black, first segment not usually lighter than remaining segments. Rostrum with segments light yellow to red, distal half or more of IV darker.

Pronotum with 2+2 longitudinal darker stripes, these sometimes faded or unclear, anterolateral margins darker, straight to slightly concave. Scutellum uniformly dark yellow to red, punctation darker, lacking stripes or macules. Pleura mostly dark yellow or red or fully darker, lighter along inner and lateral margins, and pleural surfaces in the vicinity of the coxae and sterna. Legs. Dark yellow to light red on coxae, trochanters, and half or more of femora, remaining segments darker red to black.

Connexiva dark red, densely and concolorously punctate. Abdominal venter dark yellow to red laterally and lighter yellow to red mesially sometimes with darker stripes along the intersegmental sutures and pseudosutures; sternite VII in males and females slightly more than twice as long as VI medially ( Fig. 5 ).

Male genitalia. Pygophore ( Figs 34–36 , 51–53 ). Ventral rim narrowly concave in the middle ( Fig. 34 ), rectilinear in posterior view ( Fig. 36 ). Head of parameres slightly curved, apex acute ( Fig. 47 ). Phallus ( Figs 51–53 , 57–59 ). Conjunctival processes I surpassing conjunctival processes II and III, membranous, branched, ventral branch elongate, dorsal branch apically bilobed. Conjunctival processes II sclerotized, sickle-shaped, narrowly rounded to acute at apex, subequal in width as conjunctival processes III. Conjunctival processes III sclerotized, curved basally, relatively straight on apical 2/3, almost as long as conjunctival processes II. Distal part of aedeagus rectilinear, converging to broadly rounded apex, with margins rounded.

Female genitalia ( Figs 70 , 74, 75 , 78 ). Laterotergites IX subtrapezoidal, relatively broad, anterior margin markedly angled; valvifers VIII relatively narrow, posterior margin shallowly concave ( Fig. 70 ). Spermatheca.Apical receptacle reniform, slightly longer than the intermediate part ( Figs 74 , 78 ).

Male measures (mm) (N=4). Total length 6.80–8.00; head: length 1.75–1.90, width 2.15–2.40; length of anteocular region 1.00–1.75; pronotum: length 1.90–2.10, width 4.05– 4.50; scutellum: length 3.95–4.60, width 3.70–4.20; length of sternite VI 0.05; length of sternite VII 1.10–1.20.

Female measures (mm) (N=8). Total length 6.35–9.00; head: length 1.80–2.00, width 2.40–2.70; length of anteocular region 1.00–1.20; pronotum: length 2.00–2.40, width 4.60– 4.90; scutellum: length 4.60–5.50, width 4.10–4.60; length of sternite VI 0.50; length of sternite VII 1.10–1.25.

Type material. We could not find the type of Coptochilus ferrugineus , but the description (darker color, no mention of impunctate macules on pronotum) and the type locality leave little doubt of the identity of this species.

Distribution. Brazil and Argentina ( Fig. 80 ).

Comments. EGER et al. (2015) also cited Bolivia and Ecuador in the distribution of C. ferrugineus , but these records refer to C. castaneus . Coptochilus ferrugineus is restricted to the Atlantic Rainforest [Paraná Dominion sensu MORRONE (2013)].
