Description. Adult. Colouration. Dark brown to black. Genal processes slightly lighter. Eyes dark reddish grey, ocelli yellowish. Antennal segments 1 brown, 2 light brown, 3–9 dirty whitish with brown apex and 10 dark brown to black. Head and thorax laterally lighter. Metanotum straw-coloured. Metatibia and metatarsus dirty whitish. Forewing ( Fig. 40 View FIGURES 39–50 ) coriaceous, almost opaque; ground colour dirty greyish to ochreous with dark brown or black base and patch distal to bifurcation of vein R+M+Cu, most of the remainder beset with dark, often confluent dots, particularly towards the apical wing margin; cell cu 2, apart from base, conspicuously lacking dark colour with a narrow transverse white band at base, otherwise mostly ochreous; basal part conspicuously different from remainder of wing. Hindwing greyish, with brown veins; semitransparent.Abdominal sclerites dark brown to black, intersegmental membranes yellowish to reddish. Younger specimens lighter with less expanded dark elements.

Structure. Head inclined in a 45° angle from longitudinal body axis. Vertex trapezoidal, 0.6 times as long as wide. Genal processes ( Fig. 44 View FIGURES 39–50 ) 0.8 times as long as vertex along midline, relatively broad, anteriorly shallowly incised, forming a narrower and longer submedian and a broader and shorter lateral tubercle, respectively. Antenna 1.4–1.6 times as long as head width; relative length of segment 10 and terminal setae as 1.0:0.7:0.5. Rostrum short, only tip visible in profile, 0.4–0.5 times as long as head width. Pro- and mesotibiae thickened and slightly flattened; protibia 1.3 times as long as profemur ( Fig. 48 View FIGURES 39–50 ); metatibia 0.9–1.3 times as long as head width, with 5–6 relatively evenly spaced sclerotised apical spurs. Forewing ( Fig. 40 View FIGURES 39–50 ) oval, 3.0–3.8 times as long as head width, 1.9 times as long as wide; pterostigma relatively short, ending at the level of Rs midlength; cell cu 1 0.6–0.9 times higher than wide; surface spinules forming cellular pattern covering the entire wing. Hindwing with costal setae more or less evenly spaced, not arranged in groups; short vein M+Cu developed. Male and female terminalia as in Figs 52, 56 View FIGURES 51–60 , 63 and 64 View FIGURES 61–70 . Male proctiger 0.4 times as long as head width. Paramere broadest near base, with subparallel margins in basal two thirds, narrowing to blunt apex in apical third. Female proctiger 1.0 times as long as head width; circumanal ring 0.3–0.4 times as long as proctiger; female subgenital plate 0.7 times as long as proctiger.

Measurements (in mm) (2 ♂, 2 ♀). Head width ♂ 0.56–0.66, ♀ 0.58–0.62; antenna length ♂ 0.88–0.90, ♀ 0.88–0.96; forewing length ♂ 1.82–2.00, ♀ 2.16–2.34; male proctiger length 0.24–0.26; paramere length 0.22; length of distal segment of aedeagus 0.24; female proctiger length 0.60.

Fifth instar immature. Colouration. Pale, sclerites light brown. Antennal apex brown, tip of rostrum black.

Structure. Body 1.4 times as long as wide. Antenna 0.9 times as long as forewing pad. Lateral margin of forewing pad relatively straight, giving the wing pad a parallel-sided look. Hindwing pad with one marginal sectasetae. Caudal plate 2.0 times as wide as long; with 4+4 marginal sectasetae, lacking a pair of submedian dorsal sectasetae.

Measurements (in mm) (1 immature). Body length 1.60, antenna length 0.56; forewing pad length 0.62; caudal plate width 0.80.

Etymology. Noun in apposition. This species is dedicated to the Guaraní, indigenous South American people who used to populate large areas in Paraguay, the Misiones Province of Argentina, southern Brazil and parts of Uruguay and Bolivia.

Distribution. Brazil (MG).

Host plant, biology and habitat. Copaifera langsdorffii Desf. —The immatures develop in leaf rolls which they induce.—Atlantic forest, cerrado vegetation, gallery forest.

Comments. Colophorina guarani differs from the Old World Colophorina species in the strongly inflated pro- and mesotibiae and the broadly rounded forewing. From the New World species, it differs as indicated in the key, i.e. in details of the forewing pattern and the shape of the genal processes; also, the paramere in C. guarani is wider in apical third than in the other species.
