Coptochilus lentiginosus BERG, 1879:26 (description, type locality Misiones, Argentina); LETHIERRY & SEVERIN, 1893:33 (catalog); SCHOUTEDEN, 1904:46 (distribution); KIRKALDY 1909:283 (catalog); COSCARÓN & FROESCHNER, 2000:30–31 (type data); COSCARÓN et al., 2015:94, Figs 73K, 73N (type data, illustrations); EGER et al., 2015:761 (distribution); COSCARÓN & RIDER, 2017:327 (distribution Argentina).

Medium-sized, light brown to dark yellow with irregular dark macules distributed primarily on pronotum and scutellum, black punctation relatively uniformly distributed on dorsum and laterally on the ventral surface ( Figs 7–9 ).

Head ( Figs 22–24 ) light brown to dark yellow with dark punctations, posterior and lateral margins of head and sometimes clypeus darker than the remaining surface of head. Mandibular plates acute to broadly rounded, surpassing but not converging in front of clypeus, apices moderately elevated ( Fig. 22 ). Antenniferous tubercles and antennal segment I pale, segments II–V uniformly dark. Rostrum with segments light yellow, distal half or more of segment IV dark.

Pronotum yellowish with irregular circular black macules, punctation uniformly distributed, dark.Anterolateral margins straight to slightly concave or convex. Scutellum yellow with irregular circular black spots and uniformly distributed dark punctation. Pleura light to dark yellow or fully darker; middle of pleural segments and punctation usually darker; sterna yellow, punctation mostly darker than surrounding surfaces. Legs light yellow except for half or more of tibiae and tarsi dark.

Connexiva yellow with dense, darker punctation. Abdominal venter ranging from light yellow with almost concolorous punctation laterally to dark yellow with much darker areas along intersegmental sutures, and around spiracles; punctures in these areas, if present, usually darker brown. Sternite VII in females more than twice as long as sternite VI medially ( Fig. 8 ); sternite VII in males about twice as long as sternite VI medially (1.92–2.18).

Male genitalia. Pygophore ( Figs 37–39 ). Ventral rim uniformly concave ( Fig. 37 ), slightly sinuous in posterior view ( Fig. 39 ). Head of parameres slightly curved, apex acute ( Fig. 48 ). Phallus ( Figs 60–62 ). Conjunctival processes I surpassing conjunctival processes II and III, membranous, branched, ventral branch elongate, dorsal branch apically bilobed. Conjunctival processes II sclerotized, sickle-shaped, apices acute, subequal in width as conjunctival processes III; conjunctival processes III sclerotized, almost straight, and narrowly rounded apically almost as long as conjunctival processes II. Distal part of aedeagus dilated, somewhat bilobed with margins rounded.

Female genitalia ( Figs 71 , 79 ). Laterotergites IX subtrapezoidal, broad, anterior margin markedly angled; valvifers VIII broad mesially posterior margin strongly concave ( Fig. 71 ). Spermatheca with apical receptacle subrectangular, 1.5 time longer than the intermediate part ( Fig. 79 ).

Female measures (mm)(N=10). total length 7.50– 8.90; head: length 1.75–2.00, width 2.30–2.60; length of anteocular region 1.05–1.15; pronotum: length 2.00–2.55, width 4.10–4.95; scutellum: length 4.70–5.70, width 4.30– 4.70, length of sternite VI 0.45–0.55; length of sternite VII 1.15–1.30.

Distribution. French Guiana, Brazil, Paraguay, and Argentina ( Fig. 80 ).

Comments. Collected on Cecropia sp. ( Urticaceae ). Some specimens can be fully, or partially castaneous in the ventral or dorsal view. COSCARÓN et al. (2015) provided dorsal and lateral illustrations of the type specimen. However, figure 73L (p. 93) appears to be a lateral view of Tetyra poecila Berg and figure 73N (p. 93) more closely resembles C. lentiginosus .
