Diagnosis. Genal process, in dorsal view, subconical; with subacute or narrowly rounded apex; GL/VL 0.4. Paramere, in lateral view, irregularly lamellar; anterior margin almost straight before apex; posterior margin strongly concave along apical half, weakly convex in basal half; apex truncate, strongly directed posteriorly; in dorsal view, with wavy sclerotised ridge and blunt posterior tooth, the former in lower level than the latter. Aedeagus complex tripartite; in lateral view, lateral lobule elongate, suboval; ventral process with apical expansion considerably smaller than dorsal lobe.

Description. Colouration. Body with white striped-pattern; variation: vertex with stripes along lateral and posterior margins sometimes absent; older specimens with markings with dark outline. Head and thorax dark yellow to yellowish-brown; genal process lighter than head. Eye grey to dark red; ocelli colourless to orange. Antenna light to dark yellow, segments 1–2 concolorous with head. Clypeus light yellow to concolorous with head; rostrum light yellow to dark yellow. Thorax with margins of sclerites darker. Forewing colourless, sometimes yellowish around veins M 1+2, Cu 1a and Cu 1b; veins very light yellow to very light brown; pterostigma concolorous or slightly lighter than veins. Hindwing colourless. Legs light to dark yellow with tarsi light brown, hindleg sometimes lighter than fore- and midlegs. Abdomen light straw-coloured to light brown; intersegmental membranes light straw-coloured; spiracular sclerites concolorous with tergites. Male terminalia irregularly yellowish. Female terminalia irregularly yellow, proctiger darker than subgenital plate, usually darker around anus.

Structure. Body length ♁ 2.4–2.6 mm (2.53± 0.08 mm), ♀ 2.4 mm (3 ♁, 1 ♀). Genal process ( Fig. 139 View FIGURES 133–147 ) sub-conical, evenly or irregularly narrowing towards subacute or narrowly rounded apex, 0.4 times as long as vertex along midline. Antenna 2.6 times as long as head width; longest terminal seta about as long or slightly shorter than segment 10. Apical labium segment 0.2 times longer than head width and 0.7 times longer than median segment. Forewing ( Fig. 169 View FIGURES 163–172 ) 2.7 times as long as head width, 2.2–2.3 times as long as wide, obovoid, narrowly or broadly rounded apically; vein M+Cu 1 0.4 times as long as Cu 1; ratio a/b 1.6–1.8; ratio c/d 0.7–0.9; ratio e/f 0.7–1.0. Surface spinules moderately spaced when present, forming rhomboids ( Fig. 39 View FIGURES 38–43 ); sometimes covering apical half of cells r 1 and r 2, absent or much reduced around radular areas of cells m 1, m 2 and cu 1, covering m 2 basally, and most of cell cu 2; leaving spinule-free spaces along veins ( Fig. 42 View FIGURES 38–43 ). Radular spinules sometimes present in r 2 but inconspicuous. Metatibia 0.7 times as long as head width.

Terminalia. Male. Proctiger, in lateral view, 0.4 times as long as head width; with long, strongly tapered, strongly down-curved posterior lobe. Paramere, in lateral view ( Figs 211 View FIGURES 211–219 ‾213) 0.9–1.0 times as long as proctiger; irregu-larly lamellar; anterior margin almost straight before apex; posterior margin strongly concave along apical half, weakly convex in basal half; apex truncate, strongly directed posteriorly; inner surface ( Fig. 212 View FIGURES 211–219 ) covered with long setae, longer basally and along posterior margin, with row of thick setae along apical anterior margin, several thick setae below sclerotised ridge and on apical posterior margin; in dorsal view ( Fig. 289 View FIGURES 283–312 ), with wavy sclerotised ridge and blunt posterior tooth, the former in lower level than the latter. Aedeagus ( Fig. 213 View FIGURES 211–219 ) complex tripartite; in lateral view, dorsal lobe with prominent median lobule; lateral lobule smaller than median lobule, elongate, suboval; membranous pouch rather broad; ventral process strongly upturned, with apical expansion weak, considerably smaller than dorsal lobe, bearing short, conical tubercle.—Female ( Fig. 319 View FIGURES 319–324 ). Proctiger, in lateral view, 1.0 times as long as head width; dorsal outline moderately concave distal to circumanal ring, apical extension sinuous, apex moderately upturned, smoothly obliquely truncate; circumanal ring 0.3 times as long as proctiger. Subgenital plate, in lateral view, 0.5 times as long as proctiger; apex well-developed; basal half of ventral outline strongly expanded, apical half almost straight or slightly sinuous; covered with medium long setae in median third, ventrally throughout and in apical third, long setae at apex, and group of long setae on dorsum subapically, with seta-free patch subapically; in ventral view ( Fig. 349 View FIGURES 343–362 ), lateral margins evenly, strongly narrowing at half towards narrow, subtruncate apex.

Measurements (in mm) (2 ♁, 1 ♀). HW ♁ 0.69–0.71 (0.70±0.01); AL ♁ 1.80–1.86 (1.83±0.04); LAB2 ♁ 0.18–0.20 (0.19±0.01); LAB3 ♁ 0.12–0.13 (0.13±0.01); FL ♁ 1.89–1.94 (1.91±0.04); TL ♁ 0.48–0.50 (0.49±0.02); MP ♁ 0.26–0.28 (0.27±0.01); PL ♁ 0.26; DL ♁ 0.34–0.35 (0.35±0.01); FP 0.56.

Distribution. Brazil (Bahia) ( White & Hodkinson 1980, as Acizzia ceplaciensis ). New state record for Brazil: Minas Gerais, Rio de Janeiro.

Host-plant. Adults were collected on Machaerium aculeatum Raddi and M. hirtum (Vell.) Stellfeld (Leguminosae, Papilionoideae , Aeschynomeneae) which are likely hosts.
